[0050] Please refer to Figure 1 ,Figure 1 The flowchart of a method for automatic bill verification according to an embodiment of the present application. Specifically, refer to Figure 1 As shown, the method for automatic bill verification at least includes steps S110 - S140:

[0051] Step S110, obtaining the documents to be verified;

[0052] Generally, a verification module is built into the ERP system to perform the verification operation. After the user logs in to the ERP system and starts the verification module, at this time, the system reads the documents to be verified in the database storing the documents to be verified for verification processing. In an example, a preset number of the first batch of documents to be verified can be read from the database, and after verifying the first batch of documents to be verified, the next batch of documents to be verified is taken out for verification; when all the documents to be verified in the database do not exceed the preset number, all of them are taken out at one time for verifying all the bills.

[0053] Step S120, classifying the documents to be verified to obtain one or more classifications to be verified;

[0054] Please refer to Figure 2 , Figure 2 The flowchart of classifying the documents to be verified according to an embodiment of the present application. As Figure 2 shown, classifying the documents to be verified to obtain one or more classifications to be verified includes:

[0055] S210, selecting the first verification dimension;

[0056] As an example, the first verification dimension includes at least one of the following: trading partner, trading time;

[0057] S220, classifying the documents to be verified based on the first verification dimension to obtain one or more classifications to be verified.

[0058] As an example, classifying the documents to be verified based on the first verification dimension, that is, classifying the documents to be verified according to the trading partner and trading time. For example, the documents to be verified with the same trading partner can be classified into one category, or the documents to be verified corresponding to a certain time period can be classified into one category, or the documents to be verified with the same trading partner and all within a certain time period can be classified into one category.

[0059] In an embodiment, classifying the documents to be verified to obtain one or more classifications to be verified includes:

[0060] Calculating the similarity between any two of the documents to be verified to obtain a plurality of similarity values; clustering the plurality of similarity values to obtain one or more classifications to be verified.

[0061] As an example, obtain the key fields in the documents to be written off, and calculate the cosine similarity between two documents to be written off based on the key fields. Then randomly select multiple cosine similarities as centroids, and determine the distances between multiple cosine similarities and the centroids based on the distance function. Based on the distances, allocate each cosine similarity to the cluster corresponding to the centroid with the closest distance. Re-determine the centroids of each cluster until the preset iteration condition is reached, and output the reference clustering result. Take the documents to be written off corresponding to the similarities belonging to the same cluster as a write-off classification.

[0062] As an example, randomly select multiple cosine similarities from multiple cosine similarities as the initial centroids. Here, the centroid is the center point of the cluster, representing the position of a cluster. Calculate the distances between each cosine similarity and all centroids based on the distance function to allocate each cosine similarity to the cluster corresponding to the centroid with the closest distance. After all cosine similarities are allocated to a certain cluster, re-calculate the centroid of each cluster. Here, the new centroid is usually the average value of all data points in the cluster. Repeat this process (i.e., calculate distances, allocate data points, re-determine centroids) until the preset iteration condition is reached, such as the position of the centroid no longer changes significantly, the maximum number of iterations is reached, etc. When the iteration stops, output the reference clustering result.

[0063] Step S130, obtain the associated invoices and bank statement information of each document to be written off in each write-off classification;

[0064] Please refer to Figure 3 , Figure 3 which is the flowchart of obtaining the associated invoices and bank statement information of each document to be written off in each write-off classification according to an embodiment of the present application. As Figure 3 shown, obtaining the associated invoices and bank statement information of each document to be written off in each write-off classification includes:

[0065] Step S310, identify the document to be written off to obtain the document information;

[0066] As an example, by reading the row fields of the document to be written off, the information in the document can be obtained. The document information includes: name of the trading partner, taxpayer identification number, document number, status, invoice number, invoice code, invoice date, disbursement date, etc.

[0067] Step S320, based on the document information, traverse the pre-established association relationship list to determine the associated invoices and bank statement information corresponding to the document information; among them, the association relationship list pre-stores the first association relationship between the bank statement information and the document information, and the second association relationship between the associated invoice and the document information.

[0068] It should be noted that the association relationship list is established in advance, which represents the association relationship between the document and the invoice, as well as the association relationship between the bank statement information and the trading partner.

[0069] Based on the trading partner name or document number in the document information and the association relationship list, the bank statement information of the corresponding trading partner can be determined;

[0070] Based on the document number or trading partner name in the document information and the association relationship list, the associated invoice of the corresponding document can be determined.

[0071] In another embodiment, the pre-established association relationship list can be traversed based on the document information to determine the associated invoice of the corresponding document information; among them, the association relationship between the associated invoice and the document information. Then, according to the name of the trading partner in the document information, the bank statement associated with the trading partner is called from the database to obtain the bank statement information.

[0072] Step S140, calculate the amount to be written off according to the associated invoice;

[0073] After obtaining the associated invoice, the amount recorded on the invoice, that is, the amount to be written off, can be obtained by identifying the associated invoice.

[0074] Step S150, perform a bill write-off operation according to the amount to be written off and the bank statement information.

[0075] In an embodiment of the present application, before performing the bill write-off operation, the write-off method further includes:

[0076] Judge whether the document to be written off meets the write-off conditions, and perform the write-off operation when the document to be written off meets the write-off conditions; among them, the write-off conditions include at least one of the following:

[0077] The amount to be written off is greater than 0, and the trading partner corresponding to the bank statement information is the same as the trading partner in the document to be written off.

[0078] In an embodiment, the write-off method further includes:

[0079] Set a write-off priority for the document to be written off, and when performing the bill write-off, write off the documents to be written off in sequence based on the write-off priority.

[0080] As an example, setting a write-off priority for the document to be written off includes: determining a second write-off dimension, and configuring a corresponding weight coefficient for the second write-off dimension; determining the write-off priority according to the second write-off dimension and the weight coefficient.

[0081] The second write-off dimension can be set as the transaction object and the amount, and corresponding dimension values are assigned to different transaction objects in advance, and the dimension values of more important counterparties are higher. The weight coefficient of the transaction object is 0.5, and the weight coefficient of the amount is 1. The amount of the bill to be written off A is 10,000 yuan, its dimension value is 1, and the dimension value corresponding to the transaction object is 1, then the corresponding write-off priority score is 1*1 + 1*0.5 = 1.5. The amount of the bill to be written off B is 5,000 yuan, and the dimension value corresponding to the transaction object is 1.5, then the corresponding write-off priority score is 0.5*1 + 1.5*0.5 = 1.25. Therefore, the write-off priority score of the bill to be written off A is higher, and its write-off priority is also higher. Therefore, when writing off the bills, the bill to be written off B is written off first, and then the bill to be written off B is written off. In other embodiments, other second write-off dimensions can be determined according to the actual situation, such as the payment method, etc.

[0082] In one embodiment, the obtaining of the bill to be written off includes an accounts payable bill and an accounts receivable bill.

[0083] When the bill to be written off is an accounts payable bill, obtain the accounts payable bill to be written off; classify the accounts payable bill to be written off to obtain one or more classifications of the accounts payable bill to be written off; obtain the associated invoice and bank statement information of each accounts payable bill to be written off in each classification of the accounts payable bill to be written off; calculate the amount to be written off according to the associated invoice; perform a bill write-off operation according to the amount to be written off and the bank statement information.

[0084] When the bill to be written off is an accounts receivable bill, obtain the accounts receivable bill to be written off; classify the accounts receivable bill to be written off to obtain one or more classifications of the accounts receivable bill to be written off; obtain the associated invoice and bank statement information of each accounts receivable bill to be written off in each classification of the accounts receivable bill to be written off; calculate the amount to be written off according to the associated invoice; perform a bill write-off operation according to the amount to be written off and the bank statement information.

[0085] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
