[0040] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.
[0041] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.
[0042] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.
[0043] like Figure 1 As shown, the first aspect of this application provides a method for reviewing the transaction background based on invoices, including:
[0044] Step 100: Enter the invoice and identify the invoice information, and verify the authenticity of the invoice based on the tax system.
[0045] Step 200: Link the invoice data with the transaction information and verify the transaction amount of the transaction information with the amount of the linked invoice.
[0046] In step 100, the invoice is first entered, and key information such as invoice number, date, amount, seller, and buyer is extracted. This information is used in subsequent processing. Next, using the tax system interface, the extracted information is compared with records in the tax database to verify the authenticity of the invoice. If the invoice is determined to be genuine and valid, the process continues to the next step; otherwise, if the invoice is invalid or has anomalies, it will be marked and relevant personnel will be notified for further verification.
[0047] It significantly improves the efficiency and accuracy of invoice processing, reducing errors and time consumption caused by manual operations. Automated identification and authenticity verification not only speeds up invoice review but also ensures the authenticity and legality of every invoice, thereby providing enterprises with reliable data support and reducing financial and compliance risks caused by fake invoices.
[0048] Step 200 involves entering the verified invoice data into the invoice pool and associating it with specific transaction information. This process includes verifying the consistency between invoice information and business invoices, checking the consistency between buyer / seller information and business payment / receipt information, and assessing the legality of the trade background and the invoices themselves. Furthermore, the system automatically compares the transaction amount with the associated invoice amount to ensure they match.
[0049] This step enables refined management of invoices and specific business transactions, improving the quality of business review. By verifying the consistency between transaction amounts and invoice limits, it effectively prevents the same invoice from being used multiple times or misused, enhancing financial management and risk control capabilities. This not only helps improve internal management efficiency but also ensures that all transactions comply with relevant regulations, protecting the company's legitimate rights and interests.
[0050] According to the invoice-based transaction background review method provided in the first aspect of this application, invoices are first entered and their information is identified. The authenticity of each invoice is then verified using the tax system, ensuring its validity and providing a reliable data foundation for subsequent transaction background reviews. Next, the verified invoice data is linked to specific transaction information, and the consistency between the transaction amount and the invoice amount is verified to ensure the transaction complies with regulations and is legal and compliant. This automated process efficiently and accurately verifies invoice authenticity and matches transaction information, significantly improving review efficiency, reducing errors and time consumption caused by manual operations, strengthening control over the authenticity and legality of trade backgrounds, effectively reducing financial and compliance risks, and providing strong support for enterprises.
[0051] In some embodiments of this application, invoices are entered and invoice information is identified, and the authenticity of the invoices is verified based on the tax system, specifically as follows:
[0052] Invoices are identified using electronic images and OCR recognition. The identified information includes invoice number, date, amount, seller, and buyer.
[0053] Based on the results returned by the tax system, if the invoice is determined to be genuine and valid, then the invoice passes the authenticity verification.
[0054] Based on the results returned by the tax system, if an invoice is deemed invalid, it fails the authenticity verification and is marked as invalid. Specifically, firstly, an image of the invoice is acquired using electronic imaging technology, and key information, including the invoice number, date, amount, seller, and buyer, is extracted using OCR (Optical Character Recognition) technology. This information forms the basis for subsequent verification and processing. Next, the extracted information is sent to the tax system for authenticity verification. The tax system judges the authenticity and validity of the invoice based on records in its database. If the invoice is confirmed to be authentic and valid, the process continues; if the invoice is determined to be invalid or has abnormalities, the system marks the invoice, indicating that further manual verification is required.
[0055] This method, based on electronic imaging and OCR technology combined with tax system verification, significantly improves the speed and accuracy of invoice processing, reduces errors that may occur during manual data entry and inspection, and enhances work efficiency. Secondly, by automating the authenticity verification of invoices, the authenticity and legality of each invoice are ensured, effectively preventing financial risks and compliance issues caused by counterfeit invoices. This method not only provides enterprises with reliable data support but also enhances their financial management and risk control capabilities, enabling them to focus more on the development of their core business.
[0056] In some embodiments of this application, invoice data is linked to transaction information, and the transaction amount of the transaction information and the amount of the linked invoice are verified. Specifically:
[0057] After the invoices have been verified for authenticity, they are entered into the invoice pool. The consistency of information between the invoices in the invoice pool and the business invoices is then verified.
[0058] Verify the consistency between the buyer / seller information and the payee / payer information on the business invoices;
[0059] Verify the legality of the background of business transaction information and the legality of invoices.
[0060] Specifically, in this process, invoices that have passed authenticity verification are first entered into a central database called an "invoice pool." This database stores and manages all verified authentic invoice information. Then, the system automatically performs an information consistency check to ensure that the invoice information in the invoice pool completely matches the invoice information related to the business transaction. This includes, but is not limited to, checking the consistency of key fields such as invoice number, date, and amount. Furthermore, the system further verifies whether the buyer and seller information on the business invoices matches the payee and payee information in the actual business transaction. This is to ensure the authenticity of the transaction background and avoid discrepancies between invoices and actual transactions.
[0061] By linking invoice data with specific transaction information and conducting comprehensive information consistency verification, risks arising from invoice misuse or abuse can be effectively prevented, ensuring that every transaction is based on genuine invoice information, thereby enhancing transaction security and legality. Secondly, by verifying the consistency between the buyer and seller information on business invoices and the actual payee and payee information, and by reviewing the legality of the business transaction background, potential fraudulent trade activities can be effectively identified and prevented, reducing the financial and compliance risks faced by enterprises. This method not only improves the efficiency and accuracy of financial processing but also provides enterprises with a more transparent and reliable financial management environment.
[0062] In some embodiments of this application, invoice data is linked to transaction information, and the transaction amount of the transaction information and the amount of the linked invoice are verified. The method further includes:
[0063] Automatically compare the transaction amount in the transaction information with the amount of the associated invoice;
[0064] The transaction passes verification when the transaction amount is less than or equal to the total amount on the invoice.
[0065] Specifically, during this process, the system automatically compares the transaction amount in the transaction information with the corresponding invoice amount to ensure consistency. In detail, the system compares and analyzes the amount of each transaction with the total amount recorded on the corresponding invoice. If the transaction amount is less than or equal to the total amount on the invoice, it indicates that the transaction is reasonable within the invoice's limit and thus passes verification. Conversely, if the transaction amount exceeds the total amount on the invoice, the transaction will be considered abnormal and requires further investigation and processing.
[0066] This method provides an automated and efficient way to ensure consistency between transaction amounts and invoice limits, avoiding errors and omissions that may occur with manual verification, thus significantly improving work efficiency and accuracy. Secondly, by strictly controlling transaction amounts to not exceed the total invoice limit, it effectively prevents overpayment or other forms of fund misuse, reducing the financial risks faced by the company. Furthermore, this method helps strengthen the company's internal control mechanisms, ensuring that all transactions comply with company policies and legal regulations, improving compliance and the transparency of financial management. Ultimately, this not only helps improve operational efficiency but also enhances trust in external partners, promoting healthier and more sustainable business relationships.
[0067] In some embodiments of this application, invoice data is linked to transaction information, and the transaction amount of the transaction information and the amount of the linked invoice are verified. The method further includes:
[0068] Based on the same invoice, it is stipulated that it cannot be used in multiple different types of transactions;
[0069] For the same customer under the same business type, the invoice limit can be set to allow application to multiple transactions.
[0070] Specifically, in this process, the system not only automatically compares the transaction amount in the transaction information with the associated invoice limit, but also strictly controls the scope of invoice usage. First, the system stipulates that the same invoice cannot be used for multiple different types of transactions. This means that each invoice can only correspond to one specific type of transaction, preventing invoice misuse or abuse for unrelated transactions and ensuring the specificity and legality of invoice usage. Second, for the same customer under the same business type, the system allows the invoice to be used for multiple transactions within the available invoice limit. This approach ensures both flexibility in invoice usage and, by restricting use within the same business type and customer, ensures effective management and reasonable allocation of invoice limits.
[0071] By restricting the application of a single invoice to only a single type of transaction, the reuse or misuse of invoices across different types can be effectively avoided, thereby reducing financial and legal risks. Secondly, allowing flexible application of invoice limits under the same business type and the same customer improves capital utilization efficiency while ensuring the authenticity and legality of the transaction background. Furthermore, this approach helps companies better track and manage invoice usage, strengthens internal control mechanisms, and enhances the transparency and reliability of financial management, ultimately supporting more robust and sustainable development. This refined management approach not only improves operational efficiency but also strengthens trust in external partners, fostering a healthier business cooperation environment.
[0072] In some embodiments of this application, transaction business information includes bill business, credit business and settlement business.
[0073] Specifically, bill transactions involve various forms of bill operations, such as the issuance, acceptance, and discounting of bills of exchange, promissory notes, and checks. By linking invoice data with bill transaction information and verifying the transaction amount against the invoice amount, it can be ensured that each bill is backed by a genuine and valid trade background, preventing the risks associated with counterfeit bills.
[0074] Credit business includes financial services such as loan disbursement and credit line approval. In this context, invoices, as crucial evidence proving the authenticity of trade backgrounds, are essential for credit risk control due to the veracity and legality of their information. A systematic invoice review process can effectively assess a borrower's repayment ability and creditworthiness, reducing the risk of credit default.
[0075] Settlement transactions encompass the transfer and clearing of funds, such as bank transfers and cross-border payments. Linking invoice data with settlement transaction information ensures that every fund flow is supported by a genuine trade background, helping to prevent money laundering and other financial crimes, and safeguarding the safe and stable operation of the financial system.
[0076] By strictly managing and verifying invoice information in bill trading, credit trading, and settlement trading, not only is the security and compliance of various financial transactions improved, but enterprises are also provided with powerful financial risk management tools.
[0077] In some embodiments of this application, the method further includes:
[0078] When some transactions lack invoice information, these transactions are automatically marked, and records of invoices to be supplemented are generated.
[0079] After completing the invoice supplementation, the transaction amount of the relevant transactions and the amount of the supplemented invoices are re-verified.
[0080] Specifically, when the system detects that certain transactions lack necessary invoice information, it automatically marks these transactions and generates a record of invoices to be supplemented. This automated marking mechanism can promptly identify and alert relevant personnel to potentially problematic or incomplete transactions, ensuring that every transaction has corresponding invoice support, thereby improving the integrity and reliability of the overall data. Furthermore, generating a record of invoices to be supplemented also provides a clear task list for subsequent invoice supplementation work, facilitating management and tracking.
[0081] After the invoices are entered, the system re-verifies the transaction amount against the amount of the entered invoices. This step is crucial because it ensures that all transactions undergo rigorous review and verification, even if invoice information is missing in the initial stage. This re-verification confirms that the entered invoices meet the actual needs of the transaction, guarantees consistency between the transaction amount and the invoice amount, and prevents any potential errors or violations. This method not only improves the accuracy and efficiency of transaction review but also strengthens the company's internal control mechanisms and reduces the risks caused by incomplete or erroneous information.
[0082] By automatically marking transactions with missing invoice information and generating records to be supplemented, and then re-verifying them after supplementation, comprehensive and accurate management of transaction backgrounds is achieved. This helps businesses promptly identify and resolve potential problems, ensuring that every transaction is based on genuine and valid invoice information, improving the transparency and compliance of financial processing, and also enhancing the company's risk control capabilities.
