Description

Technical Field

[0001] The present invention relates to the field of logistics technology, and in particular to a method, device, equipment and storage medium for managing invoicing information of express delivery outlets. Background Art

[0002] In the process of digital transformation in the logistics industry, invoicing information management has long faced multi-dimensional technical bottlenecks and business risks. Under the traditional model, the invoicing qualification review of express delivery outlets relies on manual verification of paper materials, which has problems such as high information entry error rate (typical error rate exceeds 15%) and serious cross-departmental data silos. Although some companies have introduced electronic systems, most solutions only implement format verification of basic fields and lack dynamic compliance verification mechanisms for core data such as taxpayer identification numbers and bank accounts, resulting in frequent financial loopholes such as false invoicing and duplicate invoicing (industry statistics show that such risk events account for 8.3%).

[0003] In terms of risk control, existing technologies generally adopt a static quota allocation model, which sets the upper limit of invoicing based on a single indicator such as registered capital or historical transaction volume. This model cannot adapt to the dynamic business scenarios unique to the logistics industry. For example, it does not consider the risk of bill fraud caused by stolen equipment at outlets (accounting for 23% of security incidents), nor does it include real-time credit fluctuations (such as overdue repayments and waybill disputes) in the evaluation system. Research shows that the bad debt rate of logistics companies using traditional static models is 1.8-2.5 percentage points higher than that of dynamic models.

[0004] In terms of technical architecture, early systems mostly used unstructured databases to store invoicing information, resulting in poor data relevance and difficulty in auditing and tracing. For example, when it is necessary to verify an abnormal invoice, it is necessary to manually retrieve log data scattered in the financial system, logistics management platform, and equipment monitoring terminal, which takes an average of more than 4 hours. In addition, although the existing blockchain evidence storage solution can achieve data immutability, it is not deeply coupled with the business rule engine and cannot automatically trigger quota recalculation or risk warning.

[0005] Therefore, the existing technology still needs to be improved and developed. Summary of the invention

[0033] The embodiments of the present invention provide a method, device, equipment and storage medium for managing the invoicing information of express delivery outlets. This method is used to manage the invoicing information of express delivery outlets and calculate their final invoicing limits. The method includes: When receiving the invoicing information submitted by the outlet, preprocess the invoicing information to obtain preprocessed invoicing information, which includes the enterprise name, taxpayer identification number, bank account, registered address and contact information; Verify the authenticity and accuracy of the preprocessed invoicing information and generate a verification certificate with a timestamp; Based on the verification certificate, screen out the outlets whose preprocessed invoicing information passes the verification, and combine the historical logistics data and real-time credit scores of the outlets to calculate the basic invoicing limit of the outlets; Obtain the equipment security level and basic risk premium of the outlet, and combine the basic invoicing limit, the equipment security level and the basic risk premium to calculate the final invoicing limit of the outlet; Save the final invoicing limit of the outlet and the corresponding preprocessed invoicing information in a relational database.

[0034] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments described here can be implemented in an order different from that shown or described here. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or equipment that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0035] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to Figure 1 , the first embodiment of a method for managing the invoicing information of express delivery outlets in the embodiments of the present invention includes:

[0036] S101. When receiving the invoicing information submitted by the outlet, preprocess the invoicing information to obtain preprocessed invoicing information, which includes the enterprise name, taxpayer identification number, bank account, registered address and contact information.

[0037] It can be understood that the execution subject of the present invention can be a device for managing the invoicing information of express delivery outlets, or a terminal or a server. Specifically, it is not limited here. The embodiments of the present invention are described by taking the server as the execution subject as an example.

[0038] In this embodiment, multiple data source interfaces are pre-configured, such as HTTP interfaces, message queue interfaces, etc., and requests from network points are listened to in real time through these multiple data source interfaces.

[0039] In this embodiment, the Kafka message queue can be used to process high-concurrency requests (supporting a peak value ≥ 5000 TPS), and the message format is in the JSON Schema standard.

[0040] In this embodiment, the invoicing information is pre-processed, including data cleaning, data conversion, format verification, etc. For example, a regular expression engine is used for format verification (such as the 18-bit verification rule for the unified social credit code).

[0041] S102. Verify the pre-processed invoicing information and generate a verification certificate with a timestamp.

[0042] In this embodiment, the pre-processed invoicing information is verified to ensure the authenticity and accuracy of the information. At the same time, a verification certificate with a timestamp is generated. The addition of the timestamp makes the verification record traceable. Once a problem occurs, the time of information verification can be accurately queried. The verification link effectively guarantees the quality of the invoicing information, prevents false or incorrect information from entering the subsequent process, and reduces the operational risk of the enterprise.

[0043] S103. Based on the verification certificate, filter out the network points that have passed the verification of the pre-processed invoicing information, and combine the historical logistics data and real-time credit scores of the network points to calculate the basic invoicing limit of the network points.

[0044] In this embodiment, the basic invoicing limit is only calculated for the network points that have passed the verification of the pre-processed invoicing information. The historical logistics data of the network points reflects the business volume and stability of the network points, and the real-time credit score reflects the current credit status of the network points. By combining these two factors to calculate the basic invoicing limit, the determination of the limit is more scientific and reasonable, which can not only encourage network points with large business volume and good credit, but also be dynamically adjusted according to the actual situation.

[0045] S104. Obtain the equipment security level and basic risk premium of the network point, and combine the basic invoicing limit, equipment security level and basic risk premium to calculate the final invoicing limit of the network point.

[0046] In this embodiment, the equipment security level and basic risk premium consider the security risk factors in the operation of the network point, so that the final invoicing limit can more comprehensively reflect the actual situation of the network point. Network points with a high equipment security level and a low risk premium will obtain a higher invoicing limit, and vice versa, thus effectively controlling the risk of the enterprise.

[0047] S105. Save the preprocessed invoicing information that has passed verification and the final invoicable amount of the network point in a relational database.

[0048] In this embodiment, the relational database has advantages such as being structured and having strong data consistency, which is convenient for data storage, query, and management. After writing to the database, the enterprise can retrieve and analyze these data at any time, providing strong data support for financial management, business decision-making, etc.

[0049] The invoicing information management method provided in this embodiment is for express delivery network points. After receiving the invoicing information submitted by the network point, it performs preprocessing, regularizes it into a standard format including enterprise name, taxpayer identification number, bank account, registered address, and contact information, greatly unifying the information form, reducing errors and process delays caused by format differences, and improving the efficiency and accuracy of subsequent data processing. Then, it verifies the preprocessed invoicing information and generates a verification certificate with a timestamp. The timestamp makes the verification record traceable, effectively ensuring the information quality, preventing false or incorrect information from entering the subsequent process, and reducing the enterprise operation risk. After that, it filters out qualified information based on the verification certificate, calculates the basic invoicable amount by combining the historical logistics data and real-time credit score of the network point, making the amount determination more scientific and reasonable, and being able to adjust dynamically according to the actual business volume and credit of the network point. Then, by obtaining the equipment safety level and basic risk premium of the network point and combining them with the basic invoicable amount, the final invoicable amount is obtained, comprehensively considering the operation safety risk of the network point and being able to reasonably control the enterprise risk. Finally, save the invoicing information that has passed verification and the final invoicable amount in a relational database, which is convenient for data storage, query, and management, and provides strong data support for the enterprise's financial management and business decision-making.

[0050] Please refer to Figure 2 , the second embodiment of the invoicing information management method for express delivery network points in the embodiments of the present invention includes:

[0051] S201. Pre-configure multiple data source interfaces and listen to the requests of the network point in real time through the multiple data source interfaces.

[0052] In this embodiment,

[0053] S202. When receiving the invoicing information submitted by the network point, perform an integrity check on the invoicing information.

[0054] In this embodiment, performing an integrity check on the invoicing information includes mandatory field verification, that is, verifying that 5 core fields such as enterprise name and taxpayer identification number are not empty. Performing an integrity check on the invoicing information also includes preliminary format screening. For example, the length of the taxpayer identification number must be 18 digits (including the check digit).

[0055] S203. Perform data cleaning and format conversion on the invoicing information that has passed the inspection to obtain preprocessed invoicing information, which includes the enterprise name, taxpayer identification number, bank account, registered address, and contact information.

[0056] In this embodiment, a dynamic cleaning strategy is implemented for data cleaning of the invoicing information that has passed the inspection, which specifically includes: for the "Enterprise Name" field, removing illegal characters (such as "★") and standardizing the ownership expression ("Limited Company" and "Limited Liability Company" are standardized). For the "Registered Address" field, parse it to the sixth-level administrative division (province-city-district-street-community-house number) based on the Gaode Map API and complete the missing levels. For the "Contact Information" field, automatically identify and convert the international format (+86 10-12345678 → +861012345678).

[0057] In this embodiment, format conversion of the invoicing information that has passed the inspection includes time format normalization. For example, identify variants such as "2025 / 3 / 14" and "14-Mar-2025" and unify them into the ISO 8601 format.

[0058] In this embodiment, multiple data source interfaces are pre-configured, and these interfaces are used to listen to the requests of the outlets in real time, broadening the information collection channels and being able to comprehensively cover the invoicing information of outlets from different sources; when receiving the invoicing information submitted by the outlets, immediately perform an integrity check on it. The integrity check can quickly identify whether there is a situation where key content is missing in the information. Only the information that passes the integrity check can enter the subsequent process, effectively preventing processing interruptions or errors caused by incomplete information and improving the stability and reliability of the entire data processing process; perform data cleaning and format conversion on the invoicing information that has passed the inspection to obtain preprocessed invoicing information. Data cleaning can remove noise data, duplicate data, and error data in the information, ensuring the accuracy and purity of the data. Format conversion unifies the invoicing information from different sources and different formats into a standard format, facilitating subsequent storage, query, and analysis, so that the data can enter the subsequent process in a regular and usable state, improving the efficiency and quality of data processing.

[0059] Please refer to Figure 3 , the third embodiment of a method for managing invoicing information of express delivery outlets in the embodiments of the present invention includes:

[0060] S301. Through the blockchain interface, compare the taxpayer identification number in the preprocessed invoicing information with the tax registration information stored on the blockchain to generate a first verification result.

[0061] In this embodiment, the taxpayer identification number is extracted from the preprocessed invoicing information and compared one by one with the corresponding tax registration information on the blockchain. If the two are exactly the same, the first verification result is generated as "passed"; if there are differences, the first verification result is generated as "not passed", and the specific difference content is recorded in detail.

[0062] S302. Load the preset account verification contract, input the bank account information in the preprocessed invoicing information into the preset account verification contract, and generate the second verification code result.

[0063] In this embodiment, the bank account information in the preprocessed invoicing information is input into the loaded account verification contract. The contract verifies the account information according to preset rules, such as whether the account length, digital format, bank code of the opening bank, etc. meet the standards. If the account information meets all the rules, the second verification result is generated as "passed"; otherwise, the result of "not passed" is generated, and the specific rule items that do not conform are pointed out.

[0064] S303. Verify the authenticity and accuracy of the enterprise name and registered address in the preprocessed invoicing information, generate the third verification result, and generate a verification certificate with a timestamp according to the first verification result, the second verification result, and the third verification result.

[0065] In this embodiment, by querying the authoritative enterprise information database (such as the interface of the National Enterprise Credit Information Publicity System), the enterprise name in the preprocessed invoicing information is compared with the registered enterprise name in the database to check whether they are the same, and at the same time, check whether there are abnormal situations such as the enterprise name has been cancelled or revoked, and generate the verification result of the enterprise name part.

[0066] Then, use the address resolution tool and the map API to resolve and locate the registered address, judge whether the address actually exists and whether the format is standard, and also compare and verify it with the address filed in the industrial and commercial registration to generate the verification result of the registered address part. Integrate these two parts of the results to generate the third verification result. Finally, integrate the first verification result, the second verification result, and the third verification result, and at the same time obtain the current accurate time as the timestamp, and generate a verification certificate with a timestamp in a specific format (such as JSON format). This verification certificate includes all verification information and results, which is convenient for subsequent reference and use.

[0067] In this embodiment, the taxpayer identification number is compared by means of blockchain technology. By leveraging the immutable characteristic of blockchain, the authenticity of tax registration information is ensured, greatly enhancing the credibility of taxpayer identification number verification. The bank account information is verified through a preset contract, and the accuracy of the account information is judged according to rigorous contract rules, ensuring the security foundation of fund transactions. Moreover, the enterprise name, registered address, and contact information are verified from multiple dimensions, comprehensively improving the overall authenticity of the information. In addition, a verification certificate with a timestamp is generated to accurately record the information verification time, providing an accurate time basis for subsequent auditing, querying, etc. Once a problem occurs, the verification link can be quickly located based on the timestamp, improving the problem-solving efficiency.

[0068] Please refer to Figure 4 , the fourth embodiment of a method for managing invoicing information of express delivery outlets in the embodiments of the present invention includes:

[0069] S401. Analyze the verification certificate and screen out the outlets whose preprocessing invoicing information has passed the verification according to the analysis result.

[0070] In this embodiment, the verification certificate is disassembled and analyzed. The verification certificate is usually stored in a specific format (such as JSON format), which contains information such as verification results and relevant outlet identifiers. Through parsing, the verification status field of each outlet is extracted to determine whether its preprocessing invoicing information has passed the verification. Traverse all the parsed verification certificates, and screen out the outlets with the verification status of "passed" to form a list of verified outlets. This list serves as the target outlet set for calculating the basic invoicing limit subsequently, ensuring that the calculation is based on the outlets with true and valid invoicing information.

[0071] S402. Obtain the logistics data and real-time credit scores of the screened outlets.

[0072] In this embodiment, connect to the logistics data storage system within the enterprise, such as a database or a data warehouse. According to the screened outlet identifiers, query the corresponding historical logistics data in the storage system. This data may include detailed logistics business information such as the shipment volume, transportation mileage, types and quantities of goods of the outlet over a period of time (such as the past year).

[0073] In this embodiment, interface with the enterprise's credit assessment system or an external credit service agency, and query and obtain the real-time credit score according to the outlet identifier. The real-time credit score may be dynamically generated based on various factors such as the recent transaction records, repayment status, and complaint handling of the outlet, reflecting the current credit status of the outlet.

[0074] S403. Combine the historical logistics data and real-time credit scores of the outlets, and perform weighted calculation using a preset invoicing limit calculation function to obtain the basic invoicing limit of the outlets.

[0075] In this embodiment, based on historical logistics data, factors such as the fluctuation of the business volume of outlets and business stability are analyzed to determine the logistics coefficient. For example, for an outlet with stable business volume and higher than the average level, the logistics coefficient can be set in a higher range (such as 1.1 - 1.2); for an outlet with large business volume fluctuations or lower than the average level, the logistics coefficient is set in a lower range (such as 0.8 - 0.9). At the same time, according to the real-time credit score, the credit coefficient of the outlet is determined. For an outlet with a high credit score, the credit coefficient is close to 1.1; for an outlet with a low credit score, the credit coefficient is close to 0.9.

[0076] For each selected outlet, a preset basic invoiceable amount calculation function is used for calculation. The preset invoiceable amount calculation function is:

[0077] The basic invoiceable amount of the outlet = initial amount * logistics coefficient * credit coefficient.

[0078] Assume that the initial amount is set at 100,000. For an outlet with a logistics coefficient of 1.0 and a credit coefficient of 1.05, substituting the determined logistics coefficient and credit coefficient into the basic invoiceable amount calculation function, the basic invoiceable amount A of the outlet = 100,000 × 1.0 × 1.05 = 105,000.

[0079] In this embodiment, outlets are screened according to verification vouchers to ensure the authenticity and accuracy of the outlet invoice information on which the subsequent calculation of the basic invoiceable amount is based, avoid deviation in amount calculation caused by false or incorrect information, and lay a solid foundation for the enterprise's financial risk control. Moreover, by combining historical logistics data and real-time credit scores to calculate the amount, historical logistics data reflects the business volume and stability of the outlet, and the real-time credit score reflects the current credit level. The two combined can comprehensively and dynamically evaluate the operation ability of the outlet, make the basic invoiceable amount conform to the actual operation status of the outlet, encourage outlets with good business and high credit, and at the same time reasonably limit the amount for outlets with poor operation, so as to achieve the optimal allocation of resources.

[0080] Please refer to Figure 5 , the fifth embodiment of a method for managing invoice information of express delivery outlets in the embodiments of the present invention includes:

[0081] S501. Obtain the equipment safety level and basic risk premium of the outlet, and determine the basic invoiceable amount coefficient of the outlet based on the equipment safety level.

[0082] In this embodiment, a special equipment safety assessment system is established in advance to regularly inspect and evaluate various equipment of the outlet (such as transport vehicles, warehousing equipment, invoicing terminals, etc.). The evaluation indicators can include the service life of the equipment, maintenance records, failure frequency, etc. According to the evaluation results, the equipment safety level of the outlet is divided into multiple levels, such as high, medium, and low.

[0083] Meanwhile, a correspondence table between different device security levels and basic invoiceable amount coefficients is preset. For example, for a network point with a device security level of "high", the basic invoiceable amount coefficient is set to 1.2; for "medium", it is set to 1.0; and for "low", it is set to 0.8. According to the obtained device security level of the network point, its basic invoiceable amount coefficient α is determined from the correspondence table.

[0084] In this embodiment, referring to the industry general standards and the enterprise's own risk assessment model, and combining the past business risk situations of the network points (such as the goods loss rate, customer complaint rate, etc.), a basic risk premium value is determined for each network point in advance.

[0085] S502. Obtain the central bank credit blacklist data and the industry risk event library. According to the central bank credit blacklist data and the industry risk event library, determine the number of blacklist matches of the network point, and calculate the dynamic risk premium of the network point based on the number of blacklist matches and the basic risk premium.

[0086] In this embodiment, connect to the central bank credit system to obtain the central bank credit blacklist data; meanwhile, establish and maintain the industry risk event library, collect and sort out various risk events occurring in the industry and the network point information involved, compare the relevant information of the network point (such as the enterprise name, taxpayer identification number, etc.) with the records in the central bank credit blacklist data and the industry risk event library, and count the number of blacklist matches of the network point in the two data sources.

[0087] According to the preset dynamic risk premium calculation function, calculate the dynamic risk premium by combining the number of blacklist matches and the basic risk premium. For example, the dynamic risk premium = basic risk premium * (number of blacklist matches + 1) × adjustment coefficient, and the adjustment coefficient can be set according to the actual situation, such as 0.1.

[0088] If the basic risk premium of a certain network point is 5%, the number of blacklist matches is 2 times, and the adjustment coefficient is 0.1, then its dynamic risk premium β = 5% * (2 + 1) * 0.1 = 1.5%.

[0089] S503. Calculate the final invoiceable amount of the network point according to the basic invoiceable amount, basic invoiceable amount coefficient and dynamic risk premium of the network point.

[0090] In this embodiment, define the final invoiceable amount of the network point as L, then the final invoiceable amount L of the network point is expressed as:

[0091]

[0092] In the formula, A represents the basic invoiceable amount of the network point, α represents the basic invoiceable amount coefficient of the network point, β represents the dynamic risk premium of the network point, and β max represents the risk premium upper limit (such as βmax = 0.8β), L min represents the minimum invoicing amount (such as 0 or the lower limit stipulated by the industry).

[0093] In this embodiment, the basic invoicing amount coefficient is determined based on the equipment safety level. Outlets with different safety levels correspond to different coefficients, enabling the final invoicing amount to be differentially set according to the actual situation of the outlets. Outlets with a high equipment safety level can obtain more favorable amount calculation coefficients, motivating outlets to improve the equipment safety level. At the same time, it also makes the amount allocation more fair and reasonable. The dynamic risk premium is calculated based on the number of blacklist matches and the basic risk premium, which can reflect the risk changes faced by the outlets in real time. With the changes in the external credit environment and the situation of the outlets themselves, the dynamic risk premium will also be adjusted accordingly, thereby affecting the final invoicing amount and realizing the dynamic management of the amount, which helps the enterprise prevent risks in a timely manner and ensure financial security.

[0094] Please refer to Figure 6 , the sixth embodiment of a method for managing invoicing information of express delivery outlets in the embodiments of the present invention includes:

[0095] S601. Extract the timestamp when the preprocessed invoicing information is verified to be passed based on the verification certificate.

[0096] In this embodiment, since the verification certificate contains rich information, including the timestamp field when the preprocessed invoicing information is verified to be passed. Use the built-in parsing tool to accurately extract this timestamp information from the verification certificate. For example, if the verification certificate is stored in JSON format, obtain the specific value of the timestamp by accessing the corresponding timestamp key-value pair, such as "2025-03-14T10:30:00Z".

[0097] S602. Call the geocoding API to convert the registered address in the preprocessed invoicing information into longitude and latitude coordinates.

[0098] In this embodiment, extract the registered address field from the preprocessed invoicing information and pass it as a parameter to the geocoding API. After receiving the request, the API parses and geolocates the registered address and returns the corresponding longitude and latitude coordinates. For example, when inputting "No. XX Road, XX District, Beijing", the API returns "Longitude: 116.481488, Latitude: 39.990464".

[0099] S603. Construct an indexing mechanism that combines the timestamp and longitude and latitude coordinates, associate the constructed index with the preprocessed invoicing information and the final invoicing amount of the outlet to obtain a mapping relationship table, and store the mapping relationship table in a relational database.

[0100] In this embodiment, combine the extracted timestamp and longitude and latitude coordinates to form a unique index.

[0101] For example, the timestamp "2025-03-14T10:30:00Z" and the longitude and latitude coordinates "Longitude: 116.481488, Latitude: 39.990464" are combined into an index form such as "20250314103000_116.481488_39.990464".

[0102] In this embodiment, the constructed index is associated with the preprocessed invoicing information (including company name, taxpayer identification number, bank account, registered address, and contact information) and the final available invoicing amount of the network point to construct a mapping relation table. Each row record in the table contains the index, complete preprocessed invoicing information, and the corresponding final available invoicing amount, forming a structured data set.

[0103] In this embodiment, a database operation tool or a connection library in a programming language, such as the pymysql library of Python, is used to connect to a relational database (such as MySQL). According to the database table structure design, an insert statement is written to write the data in the mapping relation table into the corresponding table in the database row by row.

[0104] In this embodiment, an index is constructed and a mapping relation table is formed, closely associating the timestamp, longitude and latitude coordinates with the preprocessed invoicing information and the final available invoicing amount. This structured data storage method makes operations such as data query, update, and statistics in the relational database more efficient, reduces data redundancy, and improves the performance of the database and data management efficiency.
