Description

Technical Field

[0001] The patent application of this invention belongs to the technical field of invoice verification and settlement, and specifically relates to a cloud network hall ticket intelligent verification method and system. Background Art

[0002] As the requirements for power grid development continue to increase, the total amount of power grid project construction and material procurement has increased year by year. Since 2020, the power grid has entered a stage of rapid development. At the same time, the integration of the two networks has been deepened, and contract business and process document information have increased year by year. Simple manual supervision and management can no longer meet the current business status and cannot meet the work requirements of lean management of contract settlement business. Under the current situation, the advantages of mobile Internet technology in contract settlement management business with frequent supplier docking are gradually reflected.

[0003] Mobile Internet refers to the integration of mobile communication terminals and the Internet. It is the use of mobile phones, PDAs (Personal Digital Assistants) or other wireless terminal devices to access the Internet anytime and anywhere to obtain information and use various network services while on the move (such as in subways, buses, etc.) through high-speed mobile networks. The vast majority of market consulting agencies and experts believe that mobile Internet is the new field with the most innovative vitality and market potential in the next decade. At present, mobile Internet is gradually penetrating into all areas of people's lives and work. In recent years, it has achieved a leapfrog development from 3G to 4G to 5G.

[0004] Compared with PC (Personal Computer), mobile terminals are small, light and can be carried around, so mobile commerce is easy to operate. Users transmit data through mobile communication networks and use mobile information terminals to participate in various business activities. Mobile commerce is a turning point in mobile Internet. As mobile Internet develops and matures, corporate users will increasingly use mobile Internet to conduct business activities.

[0005] At present, in the process of supplier invoice review, there are problems such as long supplier delivery process, many invoice errors and rework, many invoice verification items by the business department, and cumbersome invoice review operations. At present, the supplier review business needs to be notified by the business department by phone to deliver the invoice. After the supplier issues the invoice, he / she travels offline to a specific location and selects the corresponding contract order to deliver the invoice. The business personnel check the authenticity of the invoice and the invoice face information offline to complete the invoice review. If there is an error in a certain information of the invoice, the supplier will re-invoice and re-deliver the invoice.

[0093] The specific implementation methods of the patent application of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0094] Embodiment 1:

[0095] The present invention patent application provides a cloud network hall ticket intelligent verification method such as Figure 1 As shown, including:

[0096] Step 1: Based on the invoices uploaded by the supplier in the Cloud Network Hall Ticket Intelligent Verification APP (Application), the invoice image processing OCR recognition technology and information splicing and verification technology are used to extract the invoice file information;

[0097] Step 2: According to the invoice verification information of the invoice in the invoice resource pool of the tax platform, the authenticity of the invoice document information of the invoice is compared to obtain the authenticity comparison result;

[0098] Step 3: When the authenticity comparison result shows that the invoice is authentic, the invoice amount and tax data in the invoice file information are verified with the contract amount and tax data of the corresponding contract using the invoice intelligent verification technology to complete the invoice verification;

[0099] The invoices include single-page invoices and multi-page invoices.

[0100] The present invention aims to build a cloud network hall ticket intelligent verification APP application that can replace complex manual business operations and perform invoice notification, invoice recognition, invoice face information comparison, and invoice verification functions. The ticket intelligent verification APP of the supplier service cloud network hall system completes the digital, intelligent, and mobile contract professional intelligent APP application through basic information confirmation, order comparison, OCR recognition, invoice file parsing, invoice verification, amount verification, remarks column comparison verification, business-approved tax deviation verification and other technologies; in one implementation method, based on the invoice uploaded by the supplier in the cloud network hall ticket intelligent verification APP in step 1, the invoice image processing OCR (Optical Character Recognition) recognition technology and information splicing and verification technology are used. Before extracting the invoice file information, it also includes:

[0101] Using IoT technology, purchase order information that can be invoiced is integrated based on contract information and delivery information;

[0102] For example, the Cloud Network Hall Ticket Intelligent Verification APP of the Supplier Service Cloud Network Hall system can configure system parameters, issuer, issuer object information and other functions. It can bring out the supplier taxpayer identification number that comes with the system based on the supplier login information. The supplier can maintain the taxpayer identification number information of the invoicing object based on the invoice object information. The above information can be used as a basis for verifying the authenticity of the invoice; the integration of purchase order information is realized through the Internet of Things technology, and the confirmation of the invoicing information of batch purchase orders is realized.

[0103] Pushing the invoicable purchase order information to the supplier according to the supplier's login information;

[0104] For example, the invoicable orders can be displayed in the cloud network hall ticket intelligent verification APP of the supplier service cloud network hall system, and suppliers are urged to invoice the invoicable purchase order information;

[0105] When a supplier logs into the Cloud Network Hall Ticket Intelligent Verification APP of the Supplier Service Cloud Network Hall system, his / her identity is verified by mobile phone number, ISC (Integrated System Controller, Intel server management software) account and password. The APP pushes the corresponding invoicable order information of the supplier, including information such as delivered materials, quantity, and settleable amount.

[0106] The purchase order information includes one or more of the following: delivered materials, the quantity of delivered materials and the settleable amount.

[0107] In one implementation, the above step 1 uses invoice image processing OCR recognition technology and information splicing and checking technology to extract invoice file information based on the invoice uploaded by the supplier in the cloud network hall ticket intelligent verification APP, including:

[0108] Receive the invoice corresponding to the purchase order that can be invoiced uploaded by the supplier based on the cloud network hall ticket intelligent verification APP;

[0109] For example, the supplier uses the order information noted in the invoice remarks column of the Cloud Network Hall Ticket Intelligent Verification APP to select the invoice corresponding to the order for invoice identification and upload the invoice information.

[0110] When the invoice is a single-page invoice, invoice image processing OCR recognition technology is used to extract the invoice document information of the single-page invoice;

[0111] When the invoice is a multi-page invoice, the invoice file information of the multi-page invoice is extracted by using invoice image processing OCR recognition technology combined with information overlap verification technology;

[0112] Among them, the single-page invoice is a paper invoice or an all-electric invoice; the multi-page invoice is a paper invoice or an all-electric invoice; the flexible application of the invoice image processing OCR recognition technology of the present invention replaces the manual invoice information recognition business, and more effectively promotes the development of contract settlement business, especially in invoice recognition and electronic ticket recognition. It has broad application prospects; the present invention receives the upload of paper invoices and all-electric invoices (fully digitized electronic invoices) images through the cloud network hall ticket intelligent verification APP, performs OCR analysis and processing on the graphic files, obtains text and layout information at specific locations, and uses auxiliary information to improve the recognition accuracy, and the invoice information is linked to the corresponding purchase order to avoid the occurrence of errors in the correspondence between the invoice and the purchase order.

[0113] In one implementation, when the invoice is a single-page invoice, invoice image processing OCR recognition technology is used to extract the invoice file information of the single-page invoice, including:

[0114] Obtaining the layout information of the single-page invoice, and locating a specific position of the single-page invoice; the specific position includes the invoice header position, the line item position, and the remarks column position;

[0115] For example, invoice image processing OCR recognition technology comes from conventional visual recognition technology. Different from conventional paper character and PDF file character recognition technology, invoice image processing OCR recognition technology needs to recognize invoice pictures and images, recognize paper invoice pictures, all-electronic invoice file pictures and other invoice files in different formats, and recognize and extract invoice file information.

[0116] The Cloud Network Hall Ticket Intelligent Verification APP first receives the uploaded invoice image, analyzes and processes the graphic file, distinguishes between paper invoices and fully electronic invoices in different layout formats, and obtains specific location information such as the invoice header position, line item position, and remarks column.

[0117] Using the preset format settings, the specific location is positioned and analyzed to obtain the invoice header information, line item information and remarks column information;

[0118] For example, after obtaining the relevant location information, use flexible format settings to reposition and analyze the specific location information, obtain the seller's company code, invoice code, and invoice number information at the invoice header, obtain the invoice item amount, tax-free invoice amount, tax-inclusive total amount, and invoice tax amount at the line item position, and obtain the purchase order number, buyer's company name, and legal contract number information at the remarks column position.

[0119] The invoice header information, line item information and remarks column information are judged by using the fixed format judgment conditions required by the business. When the invoice header information, line item information and remarks column information meet the business requirements, the layout information, invoice header information, line item information and remarks column information are taken as the invoice file information of the single-page invoice and extracted;

[0120] For example, the fixed format judgment conditions required by the business are applied to make an initial judgment on the invoice header information, line item information and remarks column information to verify whether the invoice meets the business requirements and improve the OCR recognition accuracy.

[0121] Among them, the layout information includes at least one or more of the following: invoice tax number and supplier information; the invoice header information includes at least one or more of the following: seller's company code, invoice code and invoice number information; the line item information includes one or more of the following: invoice item amount, invoice amount excluding tax, total amount including tax and invoice tax amount; the notes column information includes one or more of the following: purchase order number, purchaser's company name and legal contract number information.

[0122] In one implementation, the information overlap verification technology includes: paging information overlap technology and amount superposition technology; when the invoice is a multi-page invoice, the invoice image processing OCR recognition technology is used in combination with the information overlap verification technology to extract the invoice file information of the multi-page invoice, including:

[0123] Using invoice image processing OCR recognition technology to identify the layout information of each page of the multiple pages of invoices;

[0124] For example, information extraction from multi-page invoices is a technically difficult problem. For single-page invoices, the page invoice information can be directly extracted through OCR recognition technology. For multi-page invoices, since the invoice header information, line item information, amount, and remarks column are scattered, they need to be extracted and summarized in pages. Specifically, the layout information of each page of the multi-page invoice must be identified first.

[0125] The paging information splicing technology is used to extract the invoice header information of the first page invoice, the line item information of the paging invoice, and the remarks column information and total amount information of the last page invoice of the multi-page invoice; the line item information of the paging invoice includes: itemized amount information;

[0126] For example, extract the header information from the first page invoice, extract the line item information from each page invoice, and extract the remarks column and total amount information from the last page invoice;

[0127] The amount superposition technology is used to check the item amount information and the total amount information. When the amount is checked to be correct, the layout information, invoice header information, line item information, remarks column information and total amount information are used as the invoice file information of the multi-page invoice for extraction. The present invention realizes the integrity and accuracy of information extraction of multi-page invoices through paging information splicing technology and amount superposition technology.

[0128] In one implementation, after extracting the invoice document information based on the invoice uploaded by the supplier by using the invoice image processing OCR recognition technology and information splicing verification technology, the authenticity of the invoice document information of the invoice is compared according to the invoice verification information of the invoice in the invoice resource pool of the tax platform, and before obtaining the authenticity comparison result, it also includes:

[0129] Using invoice file parsing technology, the format file of the all-electronic invoice is parsed to obtain the key information of the parsed invoice;

[0130] For example, when the all-electric invoice is recognized by OCR and the invoice information is submitted, the supplier is required to submit the all-electric invoice OFD (Open Fixed-layout Document) format file or XML (EXtensible Markup Language) format file as the basis for the all-electric invoice settlement; in actual business operations, due to the supplier's negligence, there is often a problem that the invoice recognized by OCR does not match the uploaded invoice file; here, the invoice file parsing technology is introduced to parse the content of the all-electric invoice OFD and XML format files online to extract key invoice number, order number in the remarks column, total amount and other information.

[0131] Check the key information with the corresponding information in the invoice file information, and when the information is inconsistent, return the corresponding invoice until the key information is consistent;

[0132] For example, the invoice number, order number in the remarks column, total amount and other information extracted by OCR during invoice image recognition are checked, and invoices with inconsistent verification are returned to ensure the consistency of the contract, OCR-recognized invoice and benchmark invoice file.

[0133] Among them, the format file includes one or more of the following: OFD format file and XML format file; the invoice key information includes one or more of the following: invoice number, order number in the remarks column and total amount information; the present invention performs content parsing on the OFD and XML format files of the fully electric invoice (fully digitalized electronic invoice), extracts key invoice number, order number in the remarks column, total amount and other information, and verifies the consistency of the contract, OCR-recognized invoice, and benchmark invoice file.

[0134] In one implementation, the invoice verification information includes the tax system invoice tax number, the tax system supplier information, and the tax system invoice number information; the authenticity of the invoice document information of the invoice is compared according to the invoice verification information of the invoice in the invoice resource pool of the tax platform in step 2 to obtain the authenticity comparison result, including:

[0135] Obtain the tax system invoice tax number, tax system supplier information, and tax system invoice number information of the invoice from the pre-integrated tax platform invoice resource pool;

[0136] For example, when a supplier submits an invoice offline, the authenticity of the invoice needs to be verified by a business person. The verification method is to log in to the tax system platform for verification. The ticket intelligent verification APP of the supplier service cloud network system of the present invention is integrated with the tax platform invoice resource pool, and the authenticity is automatically compared after OCR recognition of the invoice, and the tax system invoice tax number, supplier, and invoice number information are obtained in real time.

[0137] The tax system invoice tax number, the tax system supplier information, and the tax system invoice number information of the invoice are compared with the invoice tax number, the supplier information, and the invoice number information extracted from the invoice file information of the invoice to obtain an authenticity comparison result;

[0138] For example, the tax system invoice tax number, supplier, invoice number information is compared with the invoice tax number, supplier, invoice number information recognized by OCR to automatically determine the uniqueness and authenticity of the invoice and ensure that the invoice is authentic and verifiable.

[0139] When the authenticity comparison result shows that the invoice is false, the invoice will be returned until the authenticity comparison result shows that the invoice is true; the ticket intelligent verification APP of the supplier service cloud network system of the present invention integrates the invoice resource pool, obtains the invoice information of the tax system in advance, and automatically compares the authenticity after OCR recognition of the invoice, and automatically determines the uniqueness and authenticity of the invoice through information such as image, tax number, supplier, amount, invoice number, etc.

[0140] In the above step 3, when the authenticity comparison result shows that the invoice is authentic, the invoice intelligent verification technology is used to verify the invoice amount and tax amount data in the invoice file information and the contract amount and tax amount data of the corresponding contract to complete the invoice verification, including:

[0141] When the authenticity comparison result shows that the invoice is authentic, the total contract amount, the contract amount excluding tax, and the contract tax amount of the contract corresponding to the invoice are obtained;

[0142] For example, the invoice verification business is used to confirm the comparison relationship between the invoice and the contract, to ensure the accuracy of the invoice amount and the invoiced object. In the invoice settlement business of the State Grid Corporation's suppliers, the invoice verification posting is based on the receipt of goods. There may be a single purchase order with one or multiple receipts, and the consistency between the invoice amount and the purchase order receipt amount must be accurately checked.

[0143] The intelligent ticket verification APP of the supplier service cloud network system integrates contract information, delivery information, and settleable purchase order information through the Internet of Things technology. When suppliers identify and upload invoices through the intelligent ticket verification APP, they first select the purchase order to accurately confirm the invoice to be submitted, and at the same time obtain the total contract amount, tax-free contract amount, and contract tax amount of the contract corresponding to the invoice.

[0144] Verify the total amount of the invoice including tax with the total contract amount of the contract, the invoice amount excluding tax with the contract amount excluding tax of the contract, and the invoice tax amount of the invoice with the contract tax amount of the contract;

[0145] When the total contract amount is consistent with the total tax-inclusive amount, and the verification results of the invoice amount excluding tax and the contract amount excluding tax, and the invoice tax amount and the contract tax amount do not exceed the preset automatic deviation verification range, the invoice verification is completed;

[0146] For example, during the OCR recognition and review stage of invoices, an automatic deviation verification interval within the business approved range is added to realize intelligent review of invoices (the review data is displayed on the interface); according to the requirements of the contract management department for invoice review, among the three data items of invoice amount excluding tax, invoice tax amount, and total amount including tax, the total amount including tax must be consistent with the total contract amount, and the invoice amount excluding tax and the contract amount excluding tax, as well as the invoice tax amount and the contract tax amount, should be able to deviate within the range of 0-0.05 yuan. The Yunwangting Ticket Intelligent Review APP realizes range deviation review according to the above requirements.

[0147] Otherwise, the verification and error reporting will be carried out until the total contract amount is consistent with the total tax-inclusive amount, and the verification results of the invoice amount excluding tax and the contract amount excluding tax, and the invoice tax amount and the contract tax amount do not exceed the preset automatic deviation verification range, and the verification is completed;

[0148] For example, the verification and error reminder of the Yunwangting Ticket Intelligent Verification APP mainly provides error reminders for invoice verification problems, invoice amount problems, basic information errors, etc. Based on the intelligent verification function of the APP, the system automatically confirms one or more invoicing error information and provides error prompts (error information is displayed on the interface).

[0149] The Cloud Network Hall Ticket Intelligent Verification APP can also store information. The Supplier Service Cloud Network Hall system stores the correctly verified invoice information, invoice images, and file information as materials for the next step of invoice verification.

[0150] Wherein, the automatic deviation verification interval is 0-0.5.

[0151] In one implementation, when the authenticity comparison result shows that the invoice is authentic, the invoice amount and tax amount data in the invoice file information are verified with the contract amount and tax amount data of the corresponding contract using the invoice intelligent verification technology. After the invoice verification is completed, it also includes:

[0152] Based on the cloud network hall ticket intelligent verification APP, the verified invoice will be completed, the invoice verification and posting will be carried out to realize the settlement of the invoice.

[0153] For example, the expansion is integrated with the invoice verification and certification functions. When the invoice is verified to be correct, the ticket intelligent verification APP of the supplier service cloud network system can push the invoice information and order information to the invoice verification posting in real time, realize the automatic execution of invoice verification and certification, connect the invoice verification with the subsequent invoice settlement business, and further improve the efficiency of the invoice settlement business.

[0154] Through the cloud network hall ticket intelligent verification APP of the present invention, the supplier invoice verification is completed and the accuracy of invoice settlement is improved. By applying the supplier service cloud network hall system ticket intelligent verification APP, the invoice verification business can be pre-placed, and problems in the invoice settlement business can be discovered and handled in advance. The application of system intelligent verification greatly improves the accuracy of invoice settlement operations, which can effectively improve the invoice settlement efficiency by more than 80%, and the accuracy rate can reach 99.99%; reduce operating costs, apply the supplier service cloud network hall system ticket intelligent verification APP, reduce supplier travel costs, greatly reduce the manpower and physical consumption costs of business personnel, and at the same time improve the level of contract settlement business, reduce consumption, and the comprehensive operating cost can be reduced by 70%; mobile Internet operations are simple and convenient, and the supplier service cloud network hall system ticket intelligent verification APP can be applied, so that suppliers can use their free and fragmented time anytime and anywhere to conduct For invoice review and invoice information submission, business management personnel can conveniently classify and archive invoices to make full preparations for invoice verification and posting, reducing the overall settlement time from 59 days to 31 days; intelligent review management improves application experience and service level. The application of the Supplier Service Cloud Network System Ticket Intelligent Review APP can improve the accuracy of invoice verification and posting business, shorten supplier contract payment time, significantly reduce the cost of suppliers and business management departments, optimize the supplier business environment, and improve the settlement business experience and satisfaction of business management departments; invoice settlement data visualization and subsequent data full-process traceability. The application of the Supplier Service Cloud Network System Ticket Intelligent Review APP can realize the full-process online visual query of invoice review submission, invoice verification, and payment progress, forming a traceable information chain for the entire process, and the efficiency of information tracing can reach 100%.

[0155] The purpose of the present invention is mainly to solve the problems of long supplier invoice delivery process, many invoice errors and rework, many invoice verification items for business departments, and cumbersome invoice review operations, which are not conducive to the optimization of the business environment of State Grid Corporation. In the previous supplier review business, the business department needs to notify the supplier by phone to deliver the invoice. After the supplier issues the invoice, he travels offline to a specific location (the delivery location designated by each unit of State Grid Corporation) and selects the corresponding contract order to deliver the invoice. The business personnel check the authenticity of the invoice and the invoice face information offline to complete the invoice review. If there is an error in a certain information of the invoice, the supplier will re-invoice and re-deliver the invoice. The round-trip travel and manual invoice inspection will consume a lot of manpower and material resources, which is easy to cause the settlement business to be delayed, which is not conducive to the optimization of the business environment of State Grid Corporation.

[0156] The application of the cloud intelligent verification APP of the supplier service system of the present invention puts the invoice verification business in advance, and the supplier can receive the invoice information notification online as soon as the contract order is received; the application of the mobile Internet APP enables the supplier to complete the invoice identification, verification, and file upload online, and handle the wrong invoice in time. The invoice file upload function of the APP enables the business department to obtain the full-electric invoice information online, and the supplier who issues the full-electric invoice will no longer need to go to the site to deliver the invoice; the APP's intelligent invoice amount, remarks column, and invoice object verification function ensures the accuracy and authenticity of the invoice, and the business department will no longer need to manually verify the invoice face information.
