Description

Self-service intelligent input verification invoice processing system and method

technical field

The present invention relates to an invoice intelligent processing system, in particular to a self-service intelligent input and verification invoice processing system and method.

Background technique

Invoice verification on the current ERP system mostly relies on manual inspection, manual entry of invoice data, manual creation of invoice vouchers, and one-by-one posting. The invoice scanning and recognition technology is almost only used in the invoice data acquisition or authentication stage, or only the invoice data is generated into an interface file for other business systems to call. Since the invoice scanning and identification technology is not seamlessly integrated with the enterprise ERP system, it is more dependent on the buyer's personnel to complete the invoice processing work, and the overall efficiency, automation level and invoice processing capacity are still low.

Although the VAT invoice scanning and recognition technology of Hanvon Corporation is mentioned in the prior art, it has not realized the seamless integration and real-time exchange of data between the invoice scanning and recognition technology and the ERP business system; It can only be entered and automatically checked, and the seamless connection of business processes has not been realized.

Although there is a public invoice scanning system in the prior art, the public system still stays at the stage of OCR scanning and identification of invoices, and finally generates an interface file for the invoice data, which is shared and called by other systems of the company. The fully integrated content has no effective integration with the business system, no SAP invoice verification, no SAP image document storage management, and no functions such as printing of handover documents and report query.

Chinese patent (application number: 01107625.9, patent name: value-added tax invoice billing, authentication and query method and its information management system), which describes the value-added tax invoice billing and authentication, which is the business of the supplier; did not realize the supplier's The receipt of invoices, the verification of invoices and the subsequent financial processing process have not solved the problem of the relationship between orders and invoices, nor have they solved the problem of low efficiency caused by face-to-face communication between suppliers and customers.

Contents of the invention

The purpose of the present invention is to solve the above problems and provide a self-service intelligent input verification invoice processing system and method, which has the advantages of improving invoice processing efficiency and verification accuracy, reducing enterprise costs, and avoiding the advantages of suppliers waiting in line for settlement.

In order to achieve the above object, the present invention adopts the following technical solutions:

A self-service intelligent input verification invoice processing system, mainly comprising: several invoice scanning verification terminals, a database server, a backup server, and an SAP system; Both are two-way communication; the invoice scanning verification terminal includes a special scanner for invoices and a PC terminal equipped with an invoice scanning verification system client; the SAP system includes a centralized SAP invoice verification terminal, a SAP invoice verification processing platform, and an ERP DMS management system.

The method applied in the above-mentioned self-service intelligent input verification invoice processing system is divided into the following steps:

Step 1: At the beginning, the SAP invoice centralized verification terminal judges whether the invoice business is a special business; if it is a special business, go to step 5; if it is not a special business, go to step 2;

Step 2: The supplier logs in to the invoice scanning verification terminal;

Step 3: After the supplier selects the purchase contract to be settled, scan the invoice with a special invoice scanner;

Step 4: When the supplier submits the invoice data, the invoice scanning verification terminal will automatically verify the invoice data in the background, check whether the invoice and the purchase contract information are consistent, and return to step 4 if they are inconsistent; if they are consistent, save the invoice data to the local database server, and submit it to the ERP DMS management system, and then enter step six;

Step 5: Manually input invoice information for special business;

Step 6: The supplier submits the uploaded invoice to the invoice inspector, and the invoice inspector reviews the invoice data through the SAP invoice centralized inspection terminal; if the review result is correct, enter step 7, and end if it is not correct;

Step 7: The invoice inspector confirms the invoice data, and prints out the invoice receipt confirmation form to the supplier;

Step 8: The settlement accountant checks the invoice data; if the check result is correct, go to step 9; if not, go back to step 6;

Step 9: The SAP invoice verification processing platform prefabricates invoice vouchers in batches, and after verification, post to generate accounts payable, and end.

The concrete steps of described step three are:

(3-1): The supplier opens the special scanner for invoices, puts in a single invoice and covers the scanner cover as required;

(3-2): Scan and identify the invoice;

(3-3): If the order has multiple invoices, repeat step 3 to complete the scanning and identification of all invoices of the order;

(3-4): Use the invoice scanning verification terminal PC terminal equipped with the invoice scanning verification system to upload invoice data;

The concrete steps of described step 4 are:

(4-1): The invoice information is automatically verified. The system automatically verifies the invoice data in the background according to the order, ERP business data and the invoice verification rules customized by the system; if the verification rules are met, the system will prompt that the upload is successful. After the intelligent entry and automatic verification of the invoice of the order is completed, the system continues to process other orders that need to be settled this time; if the verification rule is not met, the upload will fail, and the system will also give a corresponding error message to explain the problem with the invoice. Enter (4 -2);

(4-2): The supplier checks the invoice one by one according to the above prompts to check the relevant information. If the invoice is correct, it is an identification problem of the invoice. Correct and save the invoice data according to the face information, and then enter (4-1); if the invoice is found If there is an error, and if the reason is as follows: the invoice is issued incorrectly, the correspondence between the invoice and the order is incorrect, or the number of invoices is wrong and the entry has not been completed, then you need to prepare the correct invoice corresponding to the order, delete the scanned incorrect invoice, and then go to step 3 ;

(4-3): The supplier completes all the orders that need to be settled this time, exits the system and retrieves the invoice, and ends.

The invoice scanning inspection terminal in step 4 provides a special invoice scanner to the supplier to complete the intelligent entry of invoice data by itself, for the user to scan to obtain the invoice data and send the scanned and identified picture to the ERPDMS management platform. In the SAP system The supplier and procurement contract information will be returned to the invoice scanning verification terminal;

Real-time interactive invoice data and verification status information between the invoice scanning verification terminal of step 4 and the centralized SAP invoice verification terminal of step 6;

The SAP centralized verification and verification terminal in the step 6 is used to verify the validity of the invoice, and approve whether it meets the matching of the three orders;

The SAP centralized verification terminal in step 6 sends the approved invoice data to the SAP invoice verification processing platform.

The SAP invoice verification processing platform in step 9 includes a batch prefabricated posting platform and an invoice formal posting platform, which are mainly used for automatic prefabrication of invoice vouchers and formal invoice posting;

The invoice scanning verification terminal in steps 3 and 4 provides functions including user identification, display and query of the list of contracts to be settled, invoice scanning and data acquisition, invoice data correction, and automatic verification of invoice information. The solution adopted by the system is to download the interface program through SAP and regularly synchronize the data required for inspection from the SAP system to the local database server to form the supplier information and contract information of the local database. The input and verification of invoices will be based on the data stored in the local database server. It continuously receives access requests from multiple client terminals, scans and verifies the invoice data through the invoice verification terminal, and completes the scanning identification and automatic verification of invoice data on the supplier side. Trial. The data required for self-service verification include: supplier data, contract data and buyer data. Due to the large amount of data, in consideration of reducing the load on the SAP system, the synchronization scheme for the above data is to transfer the updated data from the SAP system to the local database server regularly every day.

The contract data is used to limit the scope that the supplier can currently process the procurement contract, and to check whether the invoice data submitted by the supplier is qualified. The scope is the procurement contract that has been delivered and has not been invoiced every day. The transmitted data includes: purchase order number , purchase order amount, purchase order tax amount, settled amount (tax amount included in invoice posting), purchase contract batch settlement identifier, arrival date, factory name, supplier number, whether the contract allows settlement identifier, etc.;

The supplier data is used to verify whether the tax number is correct when the supplier logs in. As a correspondence table between the supplier number and the tax number, check whether the tax number in the invoice corresponds to the supplier number in the purchase order; the scope is the supplier For newly added or changed suppliers, the transmitted data includes: supplier number, supplier name, taxpayer identification number, supplier address and phone number, and after the supplier data is deleted or frozen in the SAP system, the data status will also be passed to Invoice scanning and identification system;

The buyer data is used to verify whether the buyer information of the invoice is correct, and the transmitted data includes: the code of the buyer, the name of the buyer, the taxpayer identification number, and the address and phone number.

The user identification means that the supplier enters the taxpayer identification number through the keyboard. When the tax number is entered correctly, the login verification is passed and the next step is entered. Otherwise, it will prompt that the tax number has been entered incorrectly and needs to be re-entered;

The display query of the list of contracts to be settled refers to that after the supplier logs in, he will be able to directly browse the list of procurement contracts that meet the settlement conditions of the unit, and display the name of the factory, storage time, amount of the contract without tax, and the total amount of the contract for each contract. Amount and other information, the supplier selects the contract that needs to be settled this time to scan the invoice, and conveniently realize the association between the invoice data and the order;

The invoice scanning and data acquisition refer to the invoice information identification function provided by the supplier through the invoice special scanner, scanning the invoice information and pictures to the PC terminal, and the PC terminal converts the unstructured information on the invoice into structured data, and the system Record the invoice scanning data and image information, and save to the local database server;

The invoice data correction refers to whether the supplier manually checks whether the seven-element data identified by scanning is correct. If all the invoice information corresponding to the order is correctly identified, upload it; otherwise, the supplier can correct the information before uploading. At this time The system will make an eye-catching mark on the modified information to prompt the invoice review personnel to confirm the revised information twice to ensure the accuracy of the invoice; the seven elements of data are 1 invoice code, 2 invoice number, 3 invoice date, 4 Amount, 5 tax amount, 6 taxpayer identification number of purchase unit, 7 taxpayer identification number of sales unit;

The automatic verification of the invoice information means that when the supplier confirms the upload, the system will check the uploaded information according to the formulated invoice data verification rules, mainly including the following aspects: whether the tax number of the buyer and seller is correct, whether the invoice date is correct, whether the invoice Whether the tax-included amount is consistent with the order tax-included amount, and whether the difference between the invoice excluding tax amount and the order excluding tax amount is within the tolerance. For the data passed the automatic verification, the system will transfer the invoice data from the local database server to the SAP system in real time, including the seven-element data scanned by the invoice, the seven-element data revised by the user, whether to modify the logo, the date of submission, and the address of the invoice picture; The failed data is stored in the local database server, which can be modified by the supplier and submitted for verification again.

The SAP centralized invoice verification terminal in step 6 provides comprehensive and up-to-date business data for the invoice verification personnel to confirm the invoice through the integrated invoice business information interface. Approve the invoice. The centralized SAP invoice verification terminal can provide inspection results of invoice information to help inspectors complete approval actions.

The SAP invoice centralized verification terminal obtains the structured data imported from the local database server in real time, displays the invoice data and corresponding procurement contract information, and automatically verifies the invoice data and displays the verification results, which are displayed in colors and warning signs Data with problems can help inspectors perform inspection and confirmation operations.

The automatic verification content of the SAP invoice centralized verification terminal in step 6 includes: whether the supplier has modified the scanned data when operating the invoice scan; whether the purchase contract data has changed on the same day; whether the purchase contract is settled in batches; Whether the amount excluding tax in the contract is consistent with the amount received; whether the difference between the amount received and not invoiced and the amount excluding tax in the invoice is within the tolerance; whether the amount including tax in the procurement contract is consistent with the total amount of the invoice.

For invoices that have been approved, the system allows rejection and reprocessing, but if the invoice has been prefabricated, this operation cannot be performed. The intelligent invoice processing system will record information such as inspection results, account numbers of inspectors, and inspection time. After the inspector completes the inspection and confirmation, the SAP system will transfer the invoice verification status of the order to the local database in real time to update the invoice verification status, and the supplier can query the invoice verification in real time through the invoice scanning verification terminal Results and other historical contract data such as the payment status of the contract.

The invoice receipt confirmation form in Step 7 lists all the invoices submitted by the supplier this time corresponding to the procurement contract. After receiving the invoices, the invoice inspector signs on the confirmation form and submits it to the supplier as an invoice handover certificate. The content includes supplier name, purchase contract number, invoice number, inspector and inspection date.

The invoice batch prefabrication and posting platform in the invoice verification processing platform in the above step 9 is enhanced and developed in the existing ERP system, which provides batch and automatic invoice voucher generation and posting functions, and can customize various types of business. Poor handling. The invoice batch prefabrication and posting program obtains the invoice data that has been verified and approved in real time from the invoice verification system, realizes the prefabrication of batch invoice vouchers, and records the invoice prefabrication voucher number for users to check the invoice content and perform invoice verification and posting, so that the main accounting processing The job is no longer entering data, but examining it.

The ERP DMS management system in step 4 is developed and implemented in the existing SAP DMS (Document Management System) system, as a storage and filing system for invoice image documents, and the association between invoice image documents and procurement contracts is established. The main process includes: the scanner scans the invoice to obtain the invoice image file; saves the invoice image file in the local database server; the ERP system regularly obtains the invoice image file from the invoice scanning system; uploads the invoice image file to the ERP DMS management system.

The invoice scanning verification terminal, the SAP invoice centralized verification terminal, and the SAP invoice verification processing platform all provide convenient invoice query functions. After users (including suppliers) log in, they can query invoice data and their current processing status in real time . The system provides multiple query conditions to facilitate the query of invoices. The query conditions provided include: purchase document number, invoice code, invoice number, invoice date, supplier tax ID, inspection date, inspection status, prefabricated voucher number, prefabricated voucher date, invoice tax declaration date, etc.

The special business in Step 5 refers to the invoice business where the buyer is not the company or the seller is not the supplier of the procurement contract but needs to complete the accounting process. Since the invoice cannot be entered through the invoice scanning system, it needs to be checked at the centralized invoice verification terminal The invoice data is manually entered and approved by the invoice reviewer.

The SAP system can also automatically match and verify the scanned invoice data in the system and the tax declaration data of the invoice, retrieve any invoice with inconsistent seven-element data between the two systems, and provide it to the management personnel for corresponding inspection and verification. Subsequent processing to meet the requirements of accounting and tax compliance.

Beneficial effects of the present invention:

Compared with the current scheme, the innovation of the scheme of the present invention is mainly reflected in the intelligent entry and automatic inspection of invoices, and the integration of invoice business rules by seamlessly integrating invoice scanning and identification with the ERP business system and exchanging data in real time In the process of invoice scanning and submission, a one-time verification is performed according to the general verification rules and business rules of the invoice and the result is fed back to the supplier, so that the supplier can complete the intelligent entry and automatic verification of the invoice by itself; the face information is verified by computer Saving labor can improve efficiency and accuracy; while some existing systems mainly stay at the OCR scanning recognition function of invoices, and then perform initial verification of invoices, and generate interface files from invoice data for shared calls by other systems of the company. It does not reflect the content of organic integration with the ERP system, and whether the invoice is accurate or not needs further verification.

After logging into the system, the supplier can see the list of contracts to be settled, choose to enter the order and then process the invoice under the order, and solve the relationship between the order and the invoice simply and effectively.

The scheme of the present invention also realizes the collaborative management of the invoice business, through which two or more different subjects or roles are coordinated to complete the invoice processing business in a coordinated manner, effectively integrate and standardize the whole process of invoice processing, and solve information islands and asymmetry, Realize the seamless connection of business processes and better manage the invoice business. The effect is reflected in:

Detailed ways

A self-service intelligent input and verification invoice processing system provides suppliers with several invoice intelligent processing terminals in a centralized invoice processing center to perform intelligent input and automatic verification of invoices. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

The processing status of invoices is divided into three categories: unfinished orders, pending approval orders, and completed orders

The unfinished orders: All orders that are allowed to be verified and settled will be listed on this interface. Under this status, it is divided into unsubmitted orders, unprocessed orders, and orders that have not passed the inspection. Unsubmitted orders refer to orders that have been scanned for invoices (including orders that have deleted or modified invoices), but have not been successfully uploaded (or not uploaded). Open orders are orders that have never been invoiced. The order that failed the verification refers to the order that was successfully uploaded but was rejected by the counter invoice reviewer for other reasons. You can upload or delete existing invoices, scan new invoices and upload them again.

The said order pending inspection: has been successfully uploaded, but has not been processed (passed or rejected) by the invoice inspector at the counter

Order.

The completed order: an order that has been uploaded successfully and has been processed by the invoice reviewer at the counter. Invoices for orders in the "Completed Order" status can still be returned if they affect the deduction or have other problems.

Step 7: The supplier checks the invoice one by one to check the relevant information according to the above prompts. If the invoice is correct, it is an identification problem of the invoice. Correct and save the invoice data according to the face information, and then go to step 6; if the invoice is found to be wrong, it may be The reasons are as follows: the invoice was issued incorrectly, the correspondence between the invoice and the order was wrong, or the number of invoices was incorrect and the input has not been completed. At this time, it is necessary to prepare the correct invoice corresponding to the order, delete the wrong invoice that has been scanned, and then go to step 3;

Step 8: Continue to process other orders that need to be settled this time;

Step 9: The supplier completes all the orders that need to be settled this time, exits the system and retrieves the invoice, and ends.

As shown in Figure 4, the working steps of the invoice processing method are divided into the following steps:

Step 1: At the beginning, the SAP invoice centralized verification terminal judges whether the invoice business is a special business; if it is a special business, go to step 5; if it is not a special business, go to step 2;

Step 2: The supplier logs into the invoice scanning verification system;

Step 3: After the supplier selects the purchase contract to be settled, scan the invoice with a special invoice scanner;

Step 4: When the supplier submits the invoice data, the invoice scanning verification terminal will automatically verify the invoice data in the background, check whether the invoice and the purchase contract information are consistent, and return to step 4 if they are inconsistent; if they are consistent, save the invoice data to the local database server, and submit it to the ERP DMS management system, and then enter step six;

Step 5: Manually input invoice information for special business;

Step 6: The supplier submits the uploaded invoice to the invoice inspector, and the invoice inspector reviews the invoice data through the SAP invoice centralized inspection terminal; if the review result is correct, enter step 7, and end if it is not correct;

Step 7: The invoice inspector confirms the invoice data, and prints out the invoice receipt confirmation form to the supplier;
