[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0056] Embodiment 1
[0057] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a bill collection control method provided by an embodiment of the present invention. Figure 1 As shown, this embodiment includes steps 101 to 104, and each step is specifically as follows:
[0058] Step 101: Get the ticket uploaded by the user.
[0059] In this embodiment, the user sends all the documents required for reimbursement (including electronic invoices, paper invoice images, online car-hailing itinerary sheets, payment receipts, payment slips, etc.) in batches to a designated collection account via email or corporate communication tools (such as WeChat for Enterprise, DingTalk, etc.), so that the entity executing the present invention obtains the documents uploaded by the user.
[0060] In a specific embodiment, the system identifies the user's identity and performs authentication by collecting the account number, and after confirmation, pulls all attachments to the system cache area.
[0061] Step 102: extract information from the bill, and generate bill information based on the extracted bill content.
[0062] In this embodiment, extracting information from the bill and obtaining bill information based on the extracted bill content includes:
[0063] Extract information from several bills through OCR recognition technology to obtain the bill content corresponding to each bill; the bill content includes: file format, bill title, bill number, time, amount, payee and payee;
[0064] The content of each bill is judged, and bill information is obtained based on the judgment result of the content of each bill; wherein the bill information includes: bill type and bill content;
[0065] If the bill title of the bill content contains invoice, the bill type corresponding to the current bill content is invoice;
[0066] If the ticket title of the ticket content contains itinerary or online ride-hailing, the ticket type corresponding to the current ticket content is set to online ride-hailing itinerary;
[0067] If the bill title of the bill content contains transfer or successful payment, the bill type corresponding to the current bill content will be set as payment voucher.
[0068] In a specific embodiment, referring to Table 1, the existing OCR technology is used to extract basic information in the attachment, and the attachment materials of the current session are classified.
[0069] Table 1
[0070]
[0071] In this embodiment, identifying the bill type corresponding to the current bill content as an invoice includes:
[0072] Determine the file format of the bill content whose bill type is invoice;
[0073] If the file format is PDF or OFD, the bill type corresponding to the current bill content is an electronic invoice, and the type of the electronic invoice is identified based on the bill number and bill title; the types of electronic invoices include: value-added tax electronic invoices and fully digitalized electronic invoices;
[0074] If the file format is image, the bill type corresponding to the current bill content is paper invoice.
[0075] Step 103: Perform relationship matching on the bills based on the bill information, associate the successfully matched bills, and obtain an associated bill combination.
[0076] In this embodiment, the process of matching bills based on bill information, associating successfully matched bills, and obtaining an associated bill combination includes:
[0077] Determine the bill type, payee, time and amount in each bill information, and generate a related bill combination based on the related bills;
[0078] If the ticket types in the two ticket information are payment receipt and online car-hailing itinerary, the payee is the same, the time is the same, and the amount is the same, then the tickets corresponding to the two ticket information are successfully matched, and the tickets corresponding to the two ticket information are associated together;
[0079] If the bill types in the two bill information are payment vouchers and electronic invoices, the payees are the same, the amounts are the same, and the time of the electronic invoice is later than the payment voucher, then the bills corresponding to the two bill information are matched successfully, and the bills corresponding to the two bill information are associated together;
[0080] Otherwise, the association between the two bills fails.
[0081] In a specific embodiment, the basic information in the attachment is extracted based on OCR technology to automatically identify and match the correspondence between the online car-hailing itinerary and the electronic invoice, and between the electronic invoice and the payment voucher / payment flow. Taking the matching process of electronic invoices and payment vouchers as an example, the user uploads multiple electronic invoice originals and screenshots of payment vouchers to the system, without the need to upload one invoice for each payment voucher separately. The system uses OCR technology to identify the issuer, amount, and issue time of the electronic invoice and the payee, amount, and payment date of the payment voucher, and establishes an association relationship between the electronic invoice and the payment voucher based on the following three conditions: the amount is consistent, the issue date is later than the payment date, and the issuer and the payee are consistent.
[0082] Step 104: After receiving the user's reimbursement demand, according to the generation time of the reimbursement demand, the associated bill combination corresponding to the generation time is retrieved to obtain the target reimbursement bill.
[0083] It should be noted that after the receipt collection is completed and the identification is successful, the user will be notified of the processing results and the number of attachments through email, corporate communication tools, etc. After the identification is successful, the user will be notified of the processing results and the number of attachments through email, corporate communication tools, etc.
[0084] In this embodiment, after obtaining the target reimbursement bill, the method further includes:
[0085] In response to the user's selection of the target reimbursement bill, the user's bill filling is completed so that the user can be reimbursed based on the filled target reimbursement bill.
[0086] It is understandable that when users reimburse expenses, after filling in the date of expense occurrence, the system will automatically retrieve and display the invoices uploaded to the system. According to the invoices with the invoice date or payment date 3 days before and after the date of the expense occurrence, users can select the invoices to be reimbursed for reimbursement. When an electronic invoice with a matching payment voucher is selected, the payment voucher with an established association will be automatically brought out for the user, without the need for the user to identify the payment voucher and manually upload the payment voucher. When the user initiates expense reimbursement and chooses to add a voucher, based on the reimbursed expense type and the tax classification, date, amount and other fields identified by the invoice, the pop-up window of the successfully matched invoice information will be displayed to the user to add the corresponding invoice, without the need for the user to manually upload and match the invoice one by one. For example, when users reimburse travel expenses, matching the uploaded online car-hailing electronic invoice and online car-hailing itinerary with the approved business trip OA itinerary associated with the user will help reduce the workload of users in manually matching electronic invoices, online car-hailing itineraries, and reimbursement processes and reduce financial risks.
