There have been systems in the past that create estimates for building renovation work (see, for example, Patent Document 1).

JP 2019-016217 A

However, with conventional technology, when a user selects a product for renovation, the details of the work to be done to install the product and the contractor are linked, and when the details of the work are selected, the product and the contractor are linked, and the work is not what the user wants. In other words, conventional technology, including the above-mentioned Patent Document 1, is unable to meet the needs of users.

The present invention was made in light of this situation, and aims to allow users to freely select the products, work content, and contractor for their renovation work.

In order to achieve the above object, an information processing system according to one aspect of the present invention comprises:
A construction content determination means for determining construction content of a building by a user's operation;
A product determination means for determining a product required for the construction work by an operation of the user;
a candidate contractor determination means for determining, by the user's operation, one or more candidate contractors from among one or more contractors capable of undertaking at least a part of the construction work for the determined construction content and the determined product;
Equipped with.

The information processing method and program of one aspect of the present invention are information processing methods and programs corresponding to the information processing device of one aspect of the present invention described above.

According to the present invention, when carrying out renovation work, the user can freely select the product to be renovated, the work content, and the contractor, and proceed with the renovation work.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an example of the configuration of an embodiment of an information processing system according to the present invention.

This service publishes a website (such as remodeling.com) related to renovation work that can be accessed by users who wish to renovate their buildings, and supports a series of tasks from estimating the renovation work to receiving and ordering the work based on the details of the renovation work selected by the user on the website (at least one of the following: product, work content, and contractor).
An information processing system applied to this service is configured, for example, as shown in FIG. 1, by connecting a server 1, user terminals 2-1 to 2-n (n is an arbitrary integer value), and contractor terminals 3-1 to 3-m (m is an arbitrary integer value independent of n) to a network N such as the Internet.

Server 1 is managed by the provider of this service. Server 1 registers one or more contractors who undertake building renovation work as at least members (affiliated stores), and also discloses a website related to building renovation work. Then, the server determines the details of the building renovation work (at least one of the following: product, work content, and contractor) through user selection on the website, and supports a series of tasks from estimating the renovation work based on the determined details to placing an order and receiving an order, and managing the subsequent construction status.

The user terminal 2 is an information processing device that accepts operations by a user who wishes to carry out renovation work, and is, for example, a personal computer, a tablet, a smartphone, or the like.
A user accesses the website from a user terminal 2, determines the contents of the renovation work by selecting the products to be renovated, the contents of the work, and a contractor, and can perform not only an estimate for the renovation work but also the work of receiving and ordering the work on the website.

In the following, when there is no need to distinguish between the n users, the user terminals 2-1 to 2-n will be collectively referred to as "user terminals 2." Furthermore, when there is no need to distinguish between the m builders, the builder terminals 3-1 to 3-m will be collectively referred to as "builder terminals 3."

In other words, the user terminal 2, in cooperation with the server 1, can execute a series of processes, such as the following, to support a series of tasks related to building renovation work, from selecting details of the renovation work (at least one of the product, work content, and contractor) to making an estimate, receiving an order, and placing an order.
Here, the method of "collaboration" is not particularly limited. For example, the user terminal 2 can adopt a first method as the "collaboration" method in which the user terminal 2 appropriately communicates with the server 1 and has the server 1 execute main processing. Also, for example, the user terminal 2 can adopt a second method as the "collaboration" method in which the user terminal 2 downloads and installs a dedicated application program (hereinafter simply referred to as an "app") from the server 1 or a device not shown under its management in advance, and executes the processing with the app. Alternatively, a method that appropriately combines the first and second methods can be adopted as the "collaboration" method.
However, for the sake of convenience, in the following example, the first method will be described as being adopted as the "collaboration" method. That is, in the following example, the subject of processing is the "server 1" for illustrative purposes only, and it goes without saying that the subject may be the "user terminal 2" as appropriate when implementing the invention.

In other words, in this example, the server 1 executes a process to support a series of tasks for building renovation work, from selecting the product, work content, and contractor, to making an estimate for the determined renovation work content, and accepting and ordering the order, while communicating appropriately with the user terminal 2 and the contractor terminal 3.

In addition, when a contract is made between a user and a contractor, the information processing system also includes, for example, an electronic signature system as a predetermined authentication authority connected to the network N.
The electronic signature system communicates with a server 1 via a network N. The electronic signature system performs electronic authentication in response to a request from the server 1.
The electronic signature system authenticates the signatures of both the user and the contractor. By registering a signature in the electronic signature system in advance, the signature is automatically authenticated when transacting with another person. At least the contractor must register his/her signature in the electronic signature system in advance.

Here, in this example, the administrator (the provider of this service) who manages server 1 does not undertake the renovation work himself, but rather the user places an order for the work with a contractor, and the contractor receives the order for the work, i.e., undertakes it.
However, this is merely an example, and the administrator may also act as an intermediary between the builder and the user in at least some of the work related to the renovation work.

In summary, the server 1 determines the construction work content for the building through the user's operation. The server 1 determines the products (commercial materials) required for the construction work through the user's operation. The server 1 also determines, through the user's operation, one or more candidate contractors from among one or more contractors who can undertake at least a portion of the construction work for the determined construction work content and products (separate ordering of the construction content and products is also possible), and can proceed with a series of renovation work such as estimates, orders, and orders that meet the user's needs with the contractor, construction content, and products determined through the user's operation.

This can provide the following effects.
In other words, when using the conventional system, when a user selected a product for renovation work, the work content and contractor of the product were linked and the work price was determined as a single option, so the user was unable to select the work content or contractor they wanted.
As a result, the renovation work did not turn out as desired, and users were forced to compromise on the lower priorities of the product, work content, and contractor.
In contrast, by using the information processing system of this embodiment, the user can freely select the products (commercial materials) to be remodeled, the work content, and the contractor to be carried out, and can proceed with the remodeling work.

In this way, in this example, server 1 executes the main processing (executes processing according to the first method described above), so the following explanation focuses on server 1 in the information processing system of Figure 1.

Figure 2 is a block diagram showing an example of the hardware configuration of a server in the information processing system shown in Figure 1.

The server 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input/output interface 15, an output unit 16, an input unit 17, a memory unit 18, a communication unit 19, and a drive 20.

The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 to the RAM 13 .
The RAM 13 also stores data and the like necessary for the CPU 11 to execute various processes.

The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input/output interface 15 is also connected to this bus 14. An output unit 16, an input unit 17, a memory unit 18, a communication unit 19, and a drive 20 are connected to the input/output interface 15.

The output unit 16 is configured with a display such as a liquid crystal display, a speaker, and the like, and outputs various information as images and sounds.
The input unit 17 is configured with, for example, a keyboard, and outputs various information.
The storage unit 18 is configured with a dynamic random access memory (DRAM) or the like, and stores various data.
The communication unit 19 communicates with other devices (such as the user terminal 2 and the contractor terminal 3 in FIG. 1) via a network N including the Internet.

Removable media 30, such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately loaded into the drive 20. Programs read from the removable media 30 by the drive 20 are installed in the storage unit 18 as necessary.
Further, the removable medium 30 can store various data stored in the storage unit 18 in the same manner as the storage unit 18 .

Although not shown, the user terminal 2 and the contractor terminal 3 in FIG. 1 can also have a configuration basically similar to the hardware configuration shown in FIG. 2. Therefore, a description of the hardware configuration of the user terminal 2 and the contractor terminal 3 will be omitted.

The various hardware and software components of the server 1 in FIG. 2 cooperate to execute processes that support a series of tasks related to building renovation work, from product (material) selection to estimates, orders, and receipt of orders.
An example of the functional configuration of the server 1 for executing such processing will be described below.

FIG. 3 is a functional block diagram illustrating an example of a functional configuration of the server in FIG.
As shown in FIG. 3, the storage unit 18 of the server 1 stores a database 121 (hereinafter referred to as "DB 121").
DB121 stores information on contractors who are registered as members (member number, contractor name, address, contact information, etc.).
DB121 stores information on the products handled on this website (product name, product number, product type (category), manufacturer, shape, catalog information such as accessories and options, standard price, dealer, etc.) corresponding to the JAN code. Standard price refers to the price agreed upon in advance with the installer.
DB121 also stores information exchanged between the user and the contractor via chat (such as information on price negotiations and additional work), as well as bidding information submitted by contractors at the user's request (such as the bid amount for construction work specified by the user).
DB121 stores the construction details for installing the product on a building (construction method (preparation, installation, removal, disposal, etc.), construction costs (construction price)) and information on contractors who can carry out this construction details (membership number, etc.).
In other words, DB 121 stores standard prices of labor charges handled on the website (unit prices of labor charges agreed upon in advance between the provider of this service and the contractor).
DB121 stores the product selected by the user, the work content, the estimate information for the renovation work estimated by the contractor (PDF file of the estimate), order information for the renovation work, order information for the renovation work that was ordered, and contract information and its terms and conditions between the user and the contractor.
The DB 121 stores schedule information related to construction (such as a schedule including product arrival date, start date, removal date, installation date, and expected completion date of construction). The DB 121 also stores information indicating the actual progress against the schedule.

As shown in FIG. 3, in the CPU 11 of the server 1, the site management unit 50 functions when a website is published.

The site management unit 50 controls the interactions between the user and the installer and the overall processing on the website.
For example, the site management unit 50 appropriately processes information exchanged between the user and the contractor, and then controls the transmission of the information from one side to the other.
For example, the site management unit 50 can hierarchically manage accounts for accessing the information processing system (restricting access according to the account's authority) and set and manage the need for access restriction for each specified unit at each hierarchy.
The site management unit 50 can also execute controls to provide various types of support when a user checks the details of an estimate or an order, for example. Checking the details of an estimate or an order includes checking the schedule, the progress of the order, and process management. Although not shown in the figure, a functional block that executes such controls is assumed to exist as a function of the site management unit 50.

The site management unit 50 includes a construction content determination unit 61, a product determination unit 62, a potential contractor determination unit 63, an estimate issuance unit 64, a notification unit 65, a communication control unit 66, an order control unit 67, a progress management unit 68, and a contractor information registration unit 69.

The construction content determination unit 61 determines the construction content of the building construction work in response to a user operation.
Specifically, the construction content determination unit 61 determines the construction content of the building construction by allowing the user to select a desired product from a group of products displayed by product type (category) on the home screen of the website, or by searching using a search box, and selecting the construction cost item (construction content) of the selected product.

The product determination unit 62 determines the products required for the construction work in response to a user operation.
Specifically, the product determination unit 62 reads from DB 121 information on the products narrowed down by the user's selection operation from the pull-down menu displayed on the refined search screen 210 (see FIG. 6), which is accessed from the home screen 200 (see FIG. 5), displays (presents) the information on the product selection screen 220, and determines the product selected by the user from that screen 220 as the product required for the construction work.

The candidate contractor determination unit 63, through user operation, determines one or more candidate contractors from among one or more contractors who are capable of undertaking at least a portion of the construction work for the determined construction content and product (separate orders are also possible).
The candidate contractor determination unit 63 presents one or more contractors capable of undertaking the construction work to the user terminal 2, and selects one or more candidate contractors selected by user operation from among the presented one or more contractors.
In addition, the candidate contractor determination unit 63 determines, through user operation, one or more candidate contractors from among one or more contractors who have responded via the contractor terminal 3 to the notification from the notification unit 65 that they are available to undertake the construction work.
Specifically, the candidate contractor determination unit 63 selects one or more contractors who can undertake at least a part of the work for the determined (including user selection) work content and product (separate ordering of the work content and product is also possible) based on the respective contractor information of the multiple contractors stored in DB 121, and determines one or more candidate contractors from the selected one or more contractors through user operation. The user operation here includes an operation to leave the selection to automatic selection, an operation to specify a contractor, etc.
The candidate contractor determination unit 63 determines, through user operation, one or more candidate contractors from among one or more contractors who have responded via the contractor terminal 3 in response to the notification from the notification unit 65 that they are available to undertake the construction work.

The estimate issuing unit 64 issues an estimate for the construction work for the determined construction content and product.
In addition, the estimate issuing unit 64 issues estimates submitted by each of the one or more candidate builders determined by the candidate contractor determining unit 63 .
Specifically, the estimate issuing unit 64 refers to DB121 to create estimate data for the renovation work to be carried out using the confirmed products (data including information on the recipient and issuer of the estimate, the names of the products and work details and their respective prices, the total amount, and tax), converts it into an estimate in PDF format, sends it to the user terminal 2, and displays (presents) it on the screen of the user terminal 2.

The notification unit 65 notifies (inquires) the contractor terminals 3 of multiple contractors as to whether or not they are able to undertake at least a portion of the work for the determined construction content and products (separate ordering of the construction content and products is also possible).
Specifically, if the user selects to have the product manufactured by contractor A and the construction by contractor B, the notification unit 65 inquires of contractor A whether it is possible to order only the product, and inquires of contractor B whether it is possible to order only the construction of the product.

The communication control unit 66 controls communication between the user terminal 2 and a specified contractor terminal 3 in order to enable communication between the user terminal 2 and a specified one of the one or more determined contractor candidates.
Specifically, the communication control unit 66 controls communication between the user terminal 2 and the contractor terminal 3 of a specified contractor, in order to enable communication between the user terminal 2 and a contractor selected by the user from one or more selected candidate contractors, or a contractor determined by the system to be suitable for the user's construction work.

The order control unit 67 performs order processing to undertake construction work based on a construction request from a user who has received a quotation.

Specifically, for example, if the quotation indicates that the product will be prepared by a home improvement store and therefore no order will be placed, but only the construction work will be ordered, the order placement and receipt control unit 67 will process the order for only the construction work based on the user's request for construction work in the quotation, and will place an order for only the construction work to the contractor who will undertake the work.
That is, the order/receive control unit 67 executes control over order processing for a contractor selected by user operation from one or more contractor candidates determined by the contractor candidate determination unit 63, and also executes control over order processing at the contractor.
In addition, in the estimate, if the work content corresponding to one product is divided into separate items, A, removal of the old kitchen, and B, installation of a new kitchen, and each item is estimated by a different contractor, the order placement control unit 67 places orders with different contractors for the work content A and B. In other words, there may be cases where orders are placed with multiple contractors.

Furthermore, as part of the control relating to order processing, the order placement and receipt control unit 67 controls processing relating to electronic contracts concluded between the user and the supplier.
Specifically, the order placement and receipt control unit 67 executes control to make an electronic contract for construction work between the user and the contractor (constructor).
When making an electronic contract, the order placement and receipt control unit 67 executes control to have the signatures of the user and the contractor (constructor) authenticated by an external authentication organization (not shown), such as an electronic signature system.

The progress management unit 68 presents to the user terminal 2 progress information indicating the progress of the construction work at the contractor.
Specifically, after the contract is made, the progress management unit 68 generates a schedule (see FIG. 13) that describes the arrival date of the actual product (commercial material) and the start date of the construction, etc., based on the contract information in the DB 121, and shares it with the user and the contractor by displaying it on the user's and the contractor's personal pages. This allows the user and the contractor to view the progress of the renovation work after the contract is made.

The contractor information registration unit 69 registers contractor information (contractor information) indicating at least one of the products that can be handled and the details of construction work, through the operation of each of a plurality of contractors.
Specifically, the contractor information registration unit 69 registers contractor information (contractor information) in DB121 indicating at least one of the products that the company can handle and the construction details, based on operations (such as registering various information) performed by a contractor who accesses his or her personal page on the website from the contractor terminal 3.
By providing the contractor information registration unit 69 in this way, the system (contractor candidate determination unit 63) automatically selects contractors who can undertake the work for the determined work content and product. In other words, by registering the products and work content that a contractor can handle in advance, the system picks up contractors who can undertake the work from among the many registered contractors, and the user can select a contractor from among the picked contractors who can perform the work.

The operation of the server having the above-described functional configuration will be described below with reference to FIGS.
In the embodiment, the server 1 discloses a website (such as reform.com) to registered users and contractors (affiliated stores) on a network N such as the Internet.
The website provides a My Page for each user and contractor, and each can use the website by logging in to their My Page.
The following describes operations mainly performed by the user, but contractors can also operate the system from their own My Page as parties undertaking construction work.
When a user requests a renovation project, the user accesses the website and logs in, whereby a home screen 200 (see FIG. 5) is displayed on the user terminal 2 as the user's personal page.
On the home screen 200, the user selects the desired work content, product, and contractor, thereby determining the content of the building renovation work.

Hereinafter, the operation of the server will be specifically described with reference to the flowchart of FIG.
FIG. 4 is a flow chart showing the operation of the server of FIG. 2 and FIG.
Figures 5 to 15 are diagrams showing examples of screens that transition through user or contractor operations on a website, and Figure 5 is a diagram showing an example of a home screen among the various screens displayed on the display unit of the user terminal of Figure 1.
When the user selects the construction content of the building construction from the home screen 200 of FIG. 5, in step S101 of FIG. 4, the construction content determination unit 61 determines the construction content of the building construction by the user's operation.
Specifically, the home screen 200 in FIG. 5 has tabs such as "HOME,""What is Reform.com?", "How to get a quote,""Reviews," and "Frequently asked questions," as well as a product search box, a product number search box, a category selection field, and a selection box for product photo icons for each product category.

In each selection box on the home screen 200 in FIG. 5, for example, names such as "Package Product", "Kitchen", ..., "Exterior", ... are displayed, and a pressing operation is performed when the user selects the construction content. In other words, the messages "Package Product", "Kitchen", ..., "Exterior", ... indicate the construction content.

When the user clicks on a selection box such as "Kitchen" on the home screen 200, the construction content determination unit 61 in FIG. 3 determines the "Kitchen" selection box clicked by the user as the construction content.

Although the home screen 200 shown in FIG. 5 has been used to explain the user's My Page, the same screen is also displayed on the contractor's My Page.
On the contractor's My Page, the contractor selects the corresponding product group, work group, and corresponding manufacturer, etc. The contractor can automatically approve a specific product group if the user specifies it. In addition, if the user requests in the form of an auction, automatic bidding can also be set. The contractor can set an original amount as the work price for the corresponding product group and work group. The standard price prepared by the website can also be used as the work price.

In this way, when the user clicks on the selection box and the construction content is determined in step S101 of FIG. 4, in step S102, the product determination unit 62 determines the products required for the construction work based on the user's operation.

Specifically, the screen displayed on the display unit of the user terminal 2 is transitioned by the product determination unit 62 from the home screen 200 shown in FIG. 5 to a refined search screen 210 shown in FIG.
FIG. 6 is a diagram showing a refinement search screen among various screens displayed on the display unit of the user terminal of FIG.
6 displays one or more pull-down menus for narrowing down kitchenware (products). The pull-down menus include, for example, manufacturer, series, kitchen layout, frontage/depth, cabinet type, dishwasher, door grade, etc. This is just one example, and other narrowing down forms may be used.

When the user makes a selection from the pull-down menu on this screen 210 and operates the “Next” button, the product decision unit 62 in FIG. 3 reads out information about the products narrowed down by the conditions in the pull-down menu from DB 121, and displays information about the products that meet the user's requirements on the product selection screen 220 shown in the next FIG. 7.
FIG. 7 is a diagram showing an example of a product selection screen among various screens displayed on the display unit of the user terminal of FIG.

That is, the product determination unit 62 in Fig. 3 presents one or more product candidates necessary for the remodeling work of the determined construction content by displaying the screen 220 shown in Fig. 7 on the user terminal 2. In this example, one product is narrowed down.
A sorting pull-down menu is located at the top right corner of this screen 220, and by selecting from the pull-down menu, the search results can be further sorted, for example, by lowest price or highest rating. Note that the sorting pull-down menu is only an example, and a keyword may be directly input, such as by price, and the menu may be located in a place other than the top right corner.

Screen 220 in FIG. 7 displays a selection box (one selection box in the example in FIG. 7) showing candidates for products (materials) required for the remodeling work with the determined work content. The user selects the product (material) required for the remodeling work from the candidates shown here. In other words, the "Select" button of the selection box displaying the selected product (material) is pressed.

In this case, the screen displayed on the display unit of the user terminal 2 transitions, for example, from screen 220 shown in FIG. 7 to a product pop-up screen 230 shown in FIG.
FIG. 8 is a diagram showing an example of a product pop-up screen among various screens displayed on the display unit of the user terminal of FIG.

Screen 230 in FIG. 8 displays an image of the product (commercial material) selected on screen 220 in FIG. 7 installed, with details of each part of the product in the image shown in a speech bubble. On the right side of the screen, the list price, selling price, and details of the product (commercial material) can be viewed, as well as an area for displaying explanations and help, and a catalog of the product's contents, such as a flat image and dimensions of the product.

In renovation work, one product (commercial material) may be composed of multiple smaller products (parts, etc.), and customization such as changing the smaller products is often possible.
In this embodiment, assuming such a case, the screen 230 in Fig. 8 is displayed. In this screen 230, information required for customization and explanations of the minor products are displayed in balloons for each minor product, so the user can refer to the balloons as appropriate to select customization. Therefore, it is very convenient to customize the layout of new products (commercial materials) while imagining the situation of remodeling the existing space of the home.
In other words, the product determination unit 62 in Figure 3 can present one or more candidate products required for the renovation work of the determined construction content, for example, by displaying not only the screen 220 in Figure 7 but also the screen 230 in Figure 8 on the user terminal 2.

On screen 220 in FIG. 7, a product (merchandise) is selected based on the user's operation on the user terminal 2, and a small product (parts, etc.) is customized. When the "Next" button in the lower right of the bottom of screen 220 is then clicked, the product determination unit 62 determines the product specifications, and displays a construction cost and additional items screen 240 on the display unit of the user terminal 2 in the form of a pop-up on screen 220, as shown in FIG. 9.

FIG. 9 is a diagram showing an example of a construction cost/additional items screen among various screens displayed on the display unit of the user terminal of FIG.
The construction cost/additional items screen 240 in FIG. 9 displays the labor costs (construction costs) and additional items columns for the products (commercial materials) selected as necessary for the remodeling construction.
In other words, the product determination unit 62 in Figure 3 can present one or more candidate products required for the renovation work of the determined construction content, for example, by displaying not only the screens of Figures 7 and 8 but also the screen 240 of Figure 9 on the user terminal 2.

While viewing screen 240 of FIG. 9, the user can add the details of the remodeling work by selecting the construction cost items for the remodeling work and one or more products (commercial materials) required for the work.
Then, when the contents of the construction cost items displayed on screen 240 are to be confirmed, the user performs a specified operation (operating the "OK" button on screen 240) to confirm the contents of the construction cost items displayed on screen 240.
By clicking on the name of each construction cost item, a help function will display a pop-up explaining the construction details.

Once the contents of the construction cost item are confirmed, the product determination unit 62 then determines one or more products (goods) that are the subject of the construction of the construction cost item confirmed by a specified operation by the user as one or more products (goods) necessary for the renovation work.

Next, in step S103 of FIG. 4, the candidate contractor determination unit 63 determines, through user operation, one or more candidate contractors from among one or more contractors who can undertake at least part of the construction work for the determined construction content and product.

Specifically, the candidate contractor determination unit 63 selects from among multiple contractors one or more contractors who can undertake at least a portion of the construction work and products selected by the user's operation or the system (separate orders for the construction work and products are also possible) based on the contractor information of each of the multiple contractors stored in DB121, and determines one or more candidate contractors from among the one or more selected contractors through the user's operation.

In addition, when the user further selects one or more candidate builders from the one or more selected builders, a remodeling company search screen 250 (see FIG. 10) linked from the homepage of the website may be displayed, for example, to acquire information on the builders.

FIG. 10 is a diagram showing an example of a renovation company search screen among various screens displayed on the display unit of the user terminal of FIG.
10, the user can obtain information on remodeling companies near the construction site by selecting, for example, prefectures, cities, towns, villages, etc. as "company search conditions" and checking the location/area of the remodeling. From the obtained information, the user can select a contractor who can handle the work on the construction site registered on this website and request an estimate.
In addition, this remodeling company search screen 250 displays reviews of remodeling companies and their construction records, so the user may select a contractor by checking the reviews, construction records, and sales prices.

In addition, on this remodeling company search screen 250, a builder designated by the user or a builder who has made a bid can increase or decrease the sales items, add or subtract the price for the sales price (price set by the builder). After that, the builder can check the user's desired construction date and select the construction date that the builder desires.
If the user does not find the desired contractor even after entering the "company search conditions", the user can submit an order for the quotation on the website and have the website administrator request the affiliated store.
In addition, if parts or additional work are required to renovate the estimate selected and created by the user, the contractor can propose a separate estimate.
In this case, the contractor can increase or decrease the sales items or add items based on the user's quotation on his/her My Page and present them to the user, and can also increase or decrease the price. After that, the construction date, etc. can be adjusted again.

The remodeling company search screen 250 of FIG. 10 can be used for an auction.
Specifically, an auction for a certain renovation project is held on the renovation company search screen 250, and a list of contractors who have submitted bids is displayed on the user's My Page. On the user's My Page, the progress of bidding on the estimated items can be confirmed. Specifically, on the My Page, the number of contractors who have submitted bids can be confirmed, and the estimated items for which bids have been submitted can be confirmed.
This allows the user to select a desired builder from one or more builders who have submitted bids and decide whether or not to make a request.
When making a bid, the builder may bid at a standard price (uniform unit price) or at the builder's own selling price. In this case, the user may present a desired price in advance.
With regard to products, the builder may bid on all of the products or on only a desired portion of the products.

In step S104 of FIG. 4, the notification unit 65 notifies (inquires) the contractor terminals 3 of the multiple contractors as to whether or not they are able to undertake at least a portion of the work for the determined work content and product (separate orders for the work content and product are also possible).

The candidate contractor determination unit 63 determines, through user operation, one or more candidate contractors from among one or more contractors who have responded to the notification from the notification unit 65 via the contractor terminal 3 that they are available to undertake the work.

When the work content, product, and contractor candidates are determined by the selection operations on the above-mentioned screens 200 to 240, an estimate screen 260 (see FIG. 11) reflecting the contents of the selection operations is displayed on the user terminal 2.
FIG. 11 is a diagram showing an example of an estimate screen among various screens displayed on the display unit of the user terminal of FIG.
Screen 260 shown in FIG. 11 includes a section for displaying quotation items, a section for the customer's signature, a section for entering special notes, a section for displaying customer information, a section for displaying home information, a section for inputting a reservation calendar, a section for displaying a quotation summary, and various buttons (such as buttons for "Add discount items,""Quotation,""Approve," and "Order").

The estimate item display field displays estimate information for the product and construction details reflecting the construction costs and additional items selected by the user on screen 240 of Figure 9, as well as a check field in which the contractor can check whether or not they have confirmed the product (product and construction details).
The unit price displayed in the quotation item display column is merely the standard price (a standard price agreed upon between the website and the affiliated store (contractor)), and the actual transaction amount may be the unit price registered by each contractor on the website, or it may be negotiable without registration.
By checking that the check box is checked, the user can ascertain whether the builder has confirmed the request details.
The customer information display field displays user information read from the member information in DB 121. The unit price displayed in the quotation item display field is the standard price set on the website that has already been agreed upon with the contractor.
In the reservation calendar, the user can input the desired date from the start date to the completion date. If there are multiple items, the desired date can be input for each item.

In screen 260 of FIG. 11, the system can automatically create an estimate using a combination of recommended builders.
The recommendations can be set according to the user's preferences (priority setting). For example, high ratings can be given priority, low prices can be given priority, or construction schedules can be given priority, and the estimate will be created based on the priority setting.

In the screen 260 of Fig. 11, separate orders can be made for each item, and an item can be selected to request an estimate from a contractor. The user can also check the response to the request for estimate for each item from the contractor. In addition, the user can customize items for which there are multiple responses.
For example, if a quote request for "Kitchen Product A" receives 700,000 yen from Builder B and 750,000 yen from Builder C, the user can customize either answer. Items for which there is no answer yet can also be checked by displaying "Unanswered" or the like.
You can also request quotes from one contractor at a time, or let the website choose the quotes for you.

In addition, for screen 260 in FIG. 11, the original quotation screen and the quotation screen with all the responses from the contractors can be opened side by side, and the estimated amount and other information on each quotation screen can be compared. Also, multiple quotation screens with responses from different contractors can be compared side by side.

Furthermore, you can request quotes for the same item from multiple contractors.
For example, a request can be made for estimates for the work separately from multiple contractors who can perform the work suited to one product (meeting the user's conditions), and an order can be placed separately from the product to the contractor with the best estimate from among the responses.

When the user clicks the “Quotation” button on screen 260 in FIG. 11 , in step S105 in FIG. 4 , the quotation issuing unit 64 issues a quotation including the product price, labor costs, etc. for one or more products determined by the product determination unit 62, and sends it to the user's My Page or the user terminal 2.
This allows the user terminal 2 to display the quotation on the display unit, print the quotation on paper, or transmit the quotation data to another terminal.

Here, the estimate issuing unit 64 can issue an estimate for the construction work based on the cost information previously agreed upon between the potential contractor for the construction work and the construction content and products decided for the construction work.
As a result, as described above, the user will be able to freely select the products (commercial materials) to be renovated, the work content, and the contractor to be carried out, and then proceed with the renovation work.
Before issuing an estimate, an estimate confirmation screen may be presented on the user terminal 2, which includes an area for the user to input an electronic signature and a “Confirm estimate” button for the user to confirm that the product (material) is necessary for the renovation work.

After the estimate is issued, the user confirms the contents of the estimate presented on the user terminal 2 and operates the ``Accept Order'' button on screen 260 in Figure 11 (screen 260 in Figure 11 shows the contractor's screen, but the user's estimate screen has an ``Order'' button), and in step S107, the order placement and receipt control unit 67 determines that the contents of the estimate have been accepted, confirms the products, work details, and contractor on the estimate, and places an order for the renovation work with the contractor.
The order control unit 67 has an order processing function, and performs order processing to undertake construction work based on a construction request from a user who has received an estimate.

The order placement and receipt control unit 67 executes control to make an electronic contract for construction work between a user who has received an estimate and the user, based on the request for construction work from the user.
Specifically, when the designated contractor confirms the contents of the terms and conditions of his/her company regarding the contents finally agreed upon by the user and the contractor and then presses the "Accept Order" button on screen 260 in Fig. 11, the order placement and receipt control unit 67 sends an electronic signature request email to the user and the contractor. If multiple contractors are included as order recipients, electronic signature request emails are sent to all of the contractors.
It is also possible to have the contractor be the main contracting party by using the "Accept Order" button on screen 260 in Fig. 11 as the user's consent button. The contractor can also press the "Accept Order" button to send an electronic signature request email, and the order can be confirmed when the user consents.
The electronic signature request email includes a link to the electronic signature system (electronic signature URL), and by clicking on the link in the email, the electronic contract is controlled by the electronic signature system. The electronic signature system authenticates the signatures of both the user and the contractor.

Here, the electronic signature and contract procedures will be described.
In the case of this embodiment, a mechanism is introduced in which an electronic signature request email with an electronic signature URL attached is sent to a user, and the user accesses the electronic signature URL to issue an electronic signature.
A typical electronic contract system requires creating a PDF of the contract and uploading it together with customer information to an electronic contract authentication system, but this is not necessary in this embodiment.

After accessing the electronic signature URL, the user may press, for example, a button to confirm the signature. The electronic signature system then determines that the contract contents have been approved, applies the selected electronic signature to the order form with terms and conditions, stores the order form in the electronic signature system's storage device, and displays a screen on the user terminal 2 indicating that the electronic contract procedure has been completed.
The user will also receive a separate email from the electronic signature system informing him or her that the electronic signature has been completed.
In addition, when the user approves the order contents by completing the electronic contract procedure, the electronic signature system transmits to the server 1 a URL indicating the storage location of the electronically signed order form with the terms and conditions.

After the user electronically signs, the order placement and receipt control unit 67 on the server 1 accesses the URL received from the electronic signature system and generates a PDF-format order confirmation from the electronically signed order form. At this time, the contractor's electronic signature is automatically entered into the order confirmation.

The construction price and product price of the products registered in DB121 have been agreed upon in advance by the company, so one of the features of this information processing system is that the electronic signature from the company, which is normally required, is automatically applied.
This eliminates the need for the user to request an electronic signature from the company. Electronic signatures can also be omitted when canceling or replacing contracts, which are common in renovation work.

After generating the order acknowledgment, the order placement and receipt control unit 67 issues an instruction to request that the builder's electronic signature be added to the order acknowledgment. Upon receiving this instruction, the order placement and receipt control unit 67 sends the order acknowledgment in PDF format to the electronic signature system and requests an electronic signature.

The electronic signature system, which receives a request for an electronic signature from server 1, processes the contractor's electronic signature on the order acknowledgment, stores the electronically signed order acknowledgment within the system, and sends a URL indicating where the order acknowledgment is stored to the requester. The electronic signature system also sends the user an email notifying the completion of the contract once both the user and the contractor have signed electronically.

In the server 1, the order control unit 67 accesses the URL received from the electronic signature system and receives the electronically signed order confirmation.
In this manner, the server 1 receives the PDF file of the electronically signed order confirmation and the PDF file of the electronically signed order form with terms and conditions from the electronic signature system.

The server 1 receives the two files and displays a selection dialog box on the top of the screen.
The selection dialog box is provided with buttons for prompting the user to select one of the options, such as Print, Email, Complete, etc., and the order control unit 67 performs a process in response to pressing of any of the buttons.

When the email button is pressed, the order placement and receipt control unit 67 sends the received PDF file of the electronically signed order confirmation and the PDF file of the electronically signed order form with terms and conditions by email to the registered destination terminal (user terminal 2) and displays them on the screen of that terminal.
When the print button is pressed, the order control unit 67 can print the document on paper using the printer set as the default.
When the completion button is pressed, the order control unit 67 ends the order processing process.

Here, the communication function will be described.
After issuing the quotation in step S105 of FIG. 4, by clicking on the “Inquire” button (not shown) displayed on screen 260 of FIG. 11, the communication control unit 66 will display chat screen 270 (see FIG. 12), allowing the user to exchange information with the contractor.

FIG. 12 is a diagram showing an example of a chat screen among various screens displayed on the display unit of the user terminal of FIG.
In the chat screen 270 shown in Fig. 12, the user and the contractor designated by the user can communicate on the website. Specifically, it is possible to send on-site photos to coordinate construction dates and contract terms. In addition, contact information can be easily shared between the user and the contractor based on customer information and company information.

While communicating via chat screen 270, it is also possible to negotiate discounts and additions or changes to construction costs that may be required based on the on-site situation.
Specifically, on the chat screen 270, a process (discount process) can be performed to discount the estimated amount by negotiating a discount on the estimate based on the estimate on the website during the chat regarding the work content or product.
The method of discount processing is not particularly limited, and may be a method of removing a decimal point from the amount, a method of discounting a certain percentage, or the like.

In this example, if it is determined that an order can be accepted, the order control unit 67 notifies the user terminal 2 or the user's personal page on the website of this fact, and executes various processes related to the order from the user for the renovation work.

For renovation work after the contract is signed, the progress management unit 68 can share information with the user and the contractor regarding the construction schedule based on the construction content determined by the construction content determination unit 61, the product determined by the product determination unit 62, and the contractor selected by the user from the candidate contractors determined by the candidate contractor determination unit 63.
That is, as described above, when multiple products (which may be multiple goods or multiple parts of one goods) are determined by the product determination unit 62, there may be products (building materials) that can be constructed at the same time, products that should be constructed, products that cannot be constructed, etc. In such a case, the progress management unit 68 can schedule an efficient construction schedule and payment date (the date of payment from the contractor's perspective) according to the relationships between these products (installation order, etc.).

The construction progress management of the remodeling work is managed by the progress management unit 68 using a progress management screen 280 (see Figure 13), and is displayed on the display units of the user terminal 2 and the contractor terminal 3.
FIG. 13 is a diagram showing an example of a progress management screen among various screens displayed on the display units of the user terminal and the contractor terminal 3 in FIG.
The progress management screen 280 shown in FIG. 13 has a calendar (date, day of the week, six-day calendar, etc.) arranged on the horizontal axis, and items for each process name arranged on the vertical axis, and a schedule corresponding to the calendar dates is appropriately displayed in the form of a Gantt chart, allowing the user to see not only the schedule for the renovation work, but also good and bad days to start work at a glance.
In the above description, the schedule on the progress management screen 280 is merely a proposal, and can be changed as appropriate by the builder performing a predetermined operation (such as a schedule change operation) on the builder terminal 3 .

Here, the function of the contractor's My Page on the website will be described with reference to Figs.
FIG. 14 is a diagram showing a basic information registration screen of the contractor's MyPage.
FIG. 15 is a diagram showing a case list screen of the contractor's My Page.
When the contractor's staff clicks on a "Register basic information" button (not shown) located on the contractor's My Page on the website, a basic information registration screen 290 shown in FIG. 14 is displayed.
The basic information registration screen 290 in Figure 14 has information input fields for registering and editing the name of the renovation company, contact information (telephone number, fax number, email address, URL of the company's website, etc.), and company overview information (overview, after-sales support, insurance, qualifications, etc., regular holidays, etc.).
In this basic information registration screen 290, the contractor can register and edit basic information about the contractor, the contractor's selling points, construction examples, and the like.

When the person in charge of the contractor clicks on a "display project" button (not shown) arranged on the contractor's personal page on the website, a project list screen 300 shown in FIG. 15 is displayed.
The case list screen 300 in FIG. 15 has a search area and a request case display area.
The search area includes a free word search input field for searching for information for which a user has requested a quote, as well as pull-down menus for selecting the person in charge, status, prefecture, and accuracy, and a field for specifying the date of the quote request.
In the request display area, the results of the search or information on new requests for quotation from users are displayed in the order of the request date.
On this case list screen 300, the contractor can search for cases for which estimates have been requested, cases for which bids can be made, and cases for which contracts have already been signed, using various conditions including free words, and display and check the list. In addition, the construction schedule can be shared and changed with users for each case. Order items can be confirmed for each case, and orders can be placed with the contractor (including payment management). In addition, a person in charge, such as a sales representative or a construction representative, can be set for each case.
In this manner, the case list screen 300 can manage cases that arise irregularly at various times.

As described above, according to the information processing system of this embodiment, the construction content of the building construction, the products required for the construction, and one or more candidate contractors are each determined by the user's operation, so that when carrying out renovation work, the user can freely select the products, construction content, and contractor to be targeted for the renovation work.
This information processing system allows users to select the product, work content, and contractor, and can consistently manage the entire process from issuing estimates to ordering, receiving orders, signing contracts, and creating documents at each stage, to managing the progress of the work thereafter, thereby providing users with a total renovation work service on the website.
When moving from estimate to contract, it is necessary to prepare contract documents in a different format from the estimate, and to coordinate construction dates between contractors before deciding on a construction schedule.

When carrying out the actual renovation work after receiving an order, time is spent on preparing documents and communication between contractors is often delayed, which can lead to construction delays. However, by introducing the information processing system of this embodiment, these steps can be eliminated, making it possible to streamline the work of the contractor who undertakes the renovation work.
In addition, this website can display payment information from the user on the user's personal page, automatically issue and show to the user invoices for the user's bank transfers, and also enable the user to pay for the renovation work by electronic payment using their credit card.

In summary, the website (reform.com) of this embodiment can provide the following effects.
(1) The website is a matching site between users and contractors, and in principle, we have no involvement in the content.
(2) Members can check the projects of all registered contractors and check the progress of projects for which they have been nominated for estimates, projects for which they have bid in an auction-style estimate, projects for which they have signed contracts, etc.
(3) If requested by the user, the user can designate a company to which the user wishes to place an order for the product (material) selected by the user.
(4) It is possible to respond to inquiries from both users and contractors.
(5) By disclosing the matching site to member users, the number of affiliated stores (constructors) and users can be increased.
In terms of the business plan, revenue sources will include the initial fees for corporate membership, monthly maintenance fees, etc., as well as XX% of the contract amount or estimated amount, and YY yen for each project, and expenses will include labor costs, development costs, advertising costs, etc. for operating the website.
The website of this embodiment has been described as functioning as a matching site between contractors and users, but it is also possible for the website to act as an intermediary site by taking the lead in entering into contracts and placing orders with contractors.

Also, for example, although not shown, functions provided in the user terminal 2 etc. can be transferred to the user's (customer's) terminal. This allows the user (customer) to request or order renovations directly (using a web app, not a web-downloaded application (so-called native app)) rather than being limited to the form of an app that is downloaded and used.

A second embodiment of the server will be described below with reference to FIGS.
First, the site notification function of the server's construction management function will be described with reference to Figs.
FIG. 16 is a diagram showing an example of a top screen among various screens displayed on the display units of the user terminal and the contractor terminal 3 in FIG.
FIG. 17 is a diagram showing a material registration screen displayed by pressing the "on-site notice" field on the top screen of FIG.
FIG. 18 is a diagram showing a registered material screen for confirming the material registered on the material registration screen of FIG.
FIG. 19 is a diagram showing a document screen displayed by pressing the "Site Photo" button on the top screen of FIG.
FIG. 20 is a diagram showing a shared chat screen displayed by pressing the "on-site comments" button on the top screen of FIG.

The server 1 of the second embodiment is provided with a construction management section (not shown) that realizes a construction management function.
The construction management section displays a top screen 310 shown in Fig. 16. The top screen 310 has a basic information section, a customer information section, and a site notice section.

The basic information section displays information such as the site name, site status, site disclosure, contract date, scheduled start date for construction, and weather forecast area.

In the customer information section, information about the client is entered for each item, such as the client's name, site address, map, email address, telephone number, fax number, mobile phone number, photo of the site exterior, and client requests.

The on-site announcements section will display announcements from others in real time.

The left end of the menu bar for each of these columns has an "Edit" button, and by pressing the button you can edit the settings for that column.

A construction management menu 311 is arranged on the left side of the top screen 310. The construction management menu 311 has a plurality of buttons arranged therein.
The multiple buttons include, for example, a "Site information" button, a "Site comments" button, a "Site documents" button, a "Site photos" button, a "Site schedule" button, an "Internal message board" button, a "Home record" button, a "Q&A" button, a "To-do list" button, and a "Summary" button.
By operating any one of these buttons, a process according to the corresponding function is executed.
By pressing the "on-site comment" button, processing is performed using the shared chat function, and the shared chat screen 350 in FIG. 20 is displayed.
By pressing the "Site Document" button, processing is performed using the site document viewing function, and a site document viewing screen (not shown) is displayed.
By pressing the "Site Photo" button, processing is performed using the site photo viewing function, and a site photo viewing screen (not shown) is displayed.
By pressing the "site schedule" button, processing is executed by the progress management unit 68, and the progress management screen 280 on which the schedule of FIG. 13 is arranged is displayed.
By pressing the "Q&A" button, processing is performed using the Q&A function, and a Q&A screen 360 in FIG. 21 is displayed.
By pressing the "ToDo List" button, processing is performed using the to-do list management function, and a to-do list display screen 370 in FIG. 22 is displayed.
By pressing the "tally" button, processing is performed using the tally function, and a tally screen 380 in FIG. 23 is displayed.

Here, a method for registering "site materials" will be described.
When the "Site Documents" button in the construction management menu 311 is pressed, a site document viewing screen (not shown) is displayed, and when the registration button on that viewing screen is pressed, a document registration screen 320 as shown in FIG. 17 is displayed.
The document registration screen 320 includes a pull-down menu for selecting the type of file to be registered, radio buttons for specifying users who can view or download the file, a file selection box, an "Edit" button for editing, etc. This screen 320 also allows the user to register documents and edit settings.
By setting users on this screen 320, only people within the range specified by the uploader can view the photos, materials, and comments.

Specifically, after a file to be registered as a material is designated on screen 320, an "Edit" button is pressed, and a registration result screen 330 as shown in FIG. 18 is displayed.
Screen 330 has basic information such as the file name, registration date, updater, update date, file description, etc., as well as fields for people who have viewed and people who have not viewed, allowing the number of people who have viewed and people who have not viewed each file to be confirmed. In addition, by pressing each number section, details of people who have viewed and people who have not viewed are displayed, allowing the uploader to check the viewing status of the uploaded file by the viewing target unit.

When registering a site photo, the "site photo" button in the construction management menu 311 is pressed, and a photo registration screen 340 as shown in FIG. 19 is displayed.
On screen 340, thumbnails of the uploaded photographs are displayed for each construction stage, for example, before construction, during construction, after construction, etc.
In this screen 340, it is possible to upload photographs with attributes of the construction stage, such as before construction, during construction, and after construction.
The construction photo can be edited on this screen 340. The edited photo can be saved under a different name from the original photo and used as an instruction photo.

Next, the shared chat function will be described.
By pressing the "Site Comments" button in the construction management menu 311 on the top screen 310, processing is executed using the shared chat function, and the shared chat screen 350 in FIG. 20 is displayed.
The shared chat screen 350 provides a screen for carrying out shared chat for each group.
On this shared chat screen 350, a plurality of people who have been registered in advance as a shared group, such as contractors (general contractors, plumbers, remodelers, etc.) and owners, can exchange chat messages.

Thus, with this shared chat function, in addition to typical two-party chat, it is possible to have multiple parties, such as between a user and a construction company, or between a contractor and a construction company, post on-site photos, and even exchange documents such as schedules, and this information can be kept as a record.
As a result, it is possible to disseminate information about important matters regarding construction work at the site. In addition, while normal chat functions require individual communication between the customer and the supplier, with shared chat communication all suppliers can see the message exchange, enabling true information sharing.

Next, the Q&A function will be described.
FIG. 21 is a diagram showing a Q&A screen displayed by pressing the "Q&A" button on the top screen of FIG.
By pressing the "Q&A" button in the construction management menu 311 on the top screen 310, processing is executed using the Q&A function, and the Q&A screen 360 in FIG. 21 is displayed.
On the Q&A screen 360, the Q&A function can automatically respond to questions about estimates, contracts, construction methods, past complaint cases, etc., using AI that has been trained using big data or teacher data accumulated in the past. It can also answer questions from customers and construction companies.
The Q&A function answers questions by quoting images such as photos, if necessary. The Q&A function includes an AI function. For example, the AI function identifies defects in the image of the house uploaded to the Q&A screen 360 and answers how to deal with the defects.
The Q&A function allows users to answer questions in a manner that sounds just like an experienced salesperson or carpenter would.

Next, the function of the ToDo list will be described.
FIG. 22 is a diagram showing a ToDo list screen displayed by pressing the "ToDo list" button on the top screen of FIG.
By pressing the "ToDo List" button in the construction management menu 311 on the top screen 310, processing is executed using the to-do list management function, and the to-do list display screen 370 in FIG. 22 is displayed.
The to-do list display screen 370 displays a to-do list.
The to-do list display screen 370 can implement a workflow in which a contractor checks off the to-do list and the client approves the contents checked by the contractor.
The to-do list changes depending on the contents of the renovation work. A to-do list exists for each type of work as a checklist for each type of work. For example, if one contract includes wallpapering, toilet work, and floor work, a checklist exists for each type of work.
The to-do list management function allows the customer to grasp the actual progress (status) of construction work, rather than just the construction schedule.
In addition, new to-do items can be created by checking a checkbox that is separate from the workflow determined by both the contractor and the customer. The to-do list management function is equipped with AI functionality, and can automatically generate to-do items in conjunction with chat content and construction information.

Next, the tallying function will be described.
FIG. 23 is a diagram showing a tally screen displayed by pressing the "tally" button on the top screen of FIG.
By pressing the "tally" button in the construction management menu 311 on the top screen 310, processing is performed using the tally function, and the tally screen 380 in FIG. 23 is displayed.
This example of a tally screen 380 is an example in which the contents of responses collected from the data stored in the DB 121 are searched for.
The tally screen 380 has columns for response type, response date, desired construction budget, desired construction location, reason for construction, type of lost order, date of lost order, reason for lost order, and remarks, and the tallying conditions can be narrowed down by inputting information into each column.
By filtering and aggregating information based on aggregation conditions, the data output will show trends regarding construction companies, such as a certain construction company's tendency to be late in reporting or starting construction late.
Furthermore, by using the compiled results, it is possible to predict how many construction projects will be delayed if a construction company carries out, for example, 100 construction projects.

The aggregation function compiles information (including statistics up to the point of contract) on each and all construction companies' response media, number of visitors, number of estimates, number of contracts, order amount, gross profit, reasons for construction, reasons for losing contracts, construction budget, order trends, and how they compare with the market through all interactions between construction companies and between construction companies and clients via server 1, accumulates the information in DB121, and outputs the compiled results.
For example, the speed of response to customers of each construction company or all construction companies, whether the scheduled start and end dates of construction are being kept, whether photos are properly uploaded, whether the to-do list is properly updated, customer feedback, etc. can be collected (including construction statistics) and fed back to the construction companies, and customers can also check the construction quality of the construction companies. In addition, the collected data can be automatically sent and searched at a specified time every month.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and modifications and improvements that can achieve the object of the present invention are included in the present invention.

In the above embodiment, the contractor is described as the person who undertakes the renovation work, but it is sufficient if the contractor is a company that can undertake at least one of the works, such as the installation of a product or the dismantling or disposal of an existing product.

In the above embodiment, in the example of screen 240 in FIG. 9, all of the construction costs and additional items are filled in, and all construction details are written to be selected (specified) by the user, but the example of screen 240 is only one example, and the user does not need to specify all construction details and products for the renovation work.

4 is merely an example, and other flowcharts may be used. For example, the estimate issuing step S105 may be replaced by the candidate vendor determination step S103.
In this case, for example, the service provider and the builder decide in advance the price to be presented in the estimate for each construction content unit or each product unit.

In the above embodiment, several examples were given of separate orders for the product, work content, and contractor. However, when making an estimate, the user can enter the product and work content in detail in one or more items, inquire of the contractor as to whether or not they will undertake the work, and obtain approval from the contractor, making it possible to place a wide range of separate orders.

For example, in the above embodiment, the information processing system performed processing to support a series of tasks from estimating to receiving and placing an order for building renovation work, but the processing is not limited to renovations.

For example, the system configuration shown in FIG. 1 and the hardware configuration of server 1 shown in FIG. 2 are merely examples for achieving the object of the present invention and are not particularly limited.

Furthermore, the functional block diagrams and databases shown in each of the above-mentioned Figures 3 are merely examples and are not particularly limited. In other words, it is sufficient that the information processing system is provided with a function that can execute the above-mentioned series of processes as a whole, and the functional blocks and databases used to realize this function are not particularly limited to the above-mentioned examples.

Furthermore, the locations of the functional blocks and databases are not limited to the example shown in FIG. 3 and may be arbitrary.
3, all the functional blocks and databases are provided in the server 1, but this is merely an example. For example, as described above, the functional blocks and databases may be executed by an application installed in the user terminal 2, or at least some of the functional blocks and databases provided in the server 1 may be provided in the user terminal 2.
Furthermore, each functional block and database may be configured as a single piece of hardware, a single piece of software, or a combination of both.

For example, the functional blocks and databases shown in FIG. 3 above are merely examples, and other functional blocks not shown may be provided in the information processing system.

When the processing of each functional block is executed by software, the program constituting the software is installed into a computer or the like from a network or a recording medium.
The computer may be a computer built into dedicated hardware, or may be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

Recording media containing such programs are not only configured as removable media that are distributed separately from the device body in order to provide each user with the program, but also configured as recording media etc. that are provided to each user in a state where they are pre-installed in the device body.

In this specification, the steps of describing a program to be recorded on a recording medium include not only processes that are performed in chronological order, but also processes that are not necessarily performed in chronological order but are executed in parallel or individually.

In addition, in this specification, the term "system" refers to an overall device that is composed of multiple devices, multiple means, etc.
