Technical field

The present application relates to the field of financial technology, and in particular, to a blank processing method for blank invoice processing, a computer readable storage medium, a server, and a device.

Background technique

At present, the flow of blank invoices is: purchase blank invoices from the tax bureau → tax filing tray → core board → billing terminal. After the blank invoice is distributed to the invoicing terminal, if the paper invoice corresponding to the blank invoice is damaged or the like, the user who needs the invoicing terminal actively applies for the blanking of the damaged blank invoice. In this process of invalidation, the enterprise's invoice management system needs to call the invalidation interface of the special tax control server (such as the tax control server of Baiwang) (the tax control invalidation interface), which is provided by the browser plug-in. Javascript interface to achieve.

However, in the process of invalidating the blank invoice, the invoice management system often calls the browser to respond slowly or even jam when calling the tax control invalidation interface. When the browser is stuck, the user closes the browser, the client computer is powered off, etc. As a result, the local invoice management system cannot obtain the return result of the tax control invalidation interface in time and accurately, so it is difficult to determine whether the result of the blank blank invoice is successful or not, which leads to the inventory of the blank invoice stored in the invoice management system and the tax control system. Inconsistent issues.

technical problem

The embodiment of the invention provides a blank invoice processing method, a storage medium and a server, which are used in the inventory and tax control system of the blank invoice which is easily stored in the invoice management system when the return result of the tax control invalid interface is not known. Inconsistent issues.

Technical solution

After determining the target invoicing terminal that needs to invalidate the blank invoice, determining whether the blank invoice available on the target invoicing terminal meets the default invalidation rule of the tax control system;

If the blank invoice available on the target invoicing terminal meets the default invalidation rule of the tax control system, the target invoice number segment to be invalidated is determined in the blank invoice available on the target invoicing terminal;

Invoking the tax control invalidation interface provided by the tax control system in the blank invoice in the target invoice number segment until all the blank invoices in the target invoice number segment are invalidated, and each time the tax control is invoked When the interface is invalidated, it is determined whether the return result of the tax control invalid interface is received;

If the return result of the tax control invalidation interface is not received, the invoice information table on the tax control system is queried to determine whether the current blank invoice is invalid. The current blank invoice refers to the tax control invalidation interface. a blank invoice to be voided, the invoice information table records information on the success or failure of each blank invoice on the tax control system;

If the current blank invoice is invalidated, the information that the current blank invoice has been invalidated is updated to the blank invoice inventory of the invoice management system, and the next blank invoice of the current blank invoice is started, and the execution is performed in turn. The blank invoice in the target invoice number segment invokes the step of the tax control invalidation interface provided by the tax control system;

If the current blank invoice is not invalidated, starting from the current blank invoice, returning to the step of invoking the tax control invalidation interface provided by the tax control system for the blank invoice in the target invoice number segment.

Embodiments of the invention

Referring to FIG. 1 , an embodiment of a method for processing a blank invoice in an embodiment of the present application includes:

After determining the target invoicing terminal that needs to invalidate the blank invoice, determining whether the blank invoice available on the target invoicing terminal meets the default invalidation rule of the tax control system, and if yes, executing step 103; if not, executing step 102 ;

In this embodiment, the user may log in to the invoice management system first. When logging in, the user needs to verify the user's account number, password, and the like. If the verification is passed, the user is successfully logged into the invoice management system. At this point, the invoice management system can automatically load which invoicing terminals are under the user's administrative authority. After loading, the user can select one invoicing terminal as the target invoicing terminal as needed.

After the target billing terminal is determined, the invoice management system needs to determine whether the blank invoice available on the target invoicing terminal meets the default invalidation rule of the tax control system. At present, the tax control system strictly limits the invalidation of blank invoices, and the limitation is achieved by prescribing the invalidation rules. For example, the above-mentioned default invalidation rule may include: a blank blank invoice must be under the target invoicing terminal, that is, one invoicing terminal cannot invalidate a blank invoice on another invoicing terminal; the blank blank invoice must be the target invoicing The first available blank invoice for the terminal; and so on. Since the invoicing terminal needs to invoice in strict accordance with the invoice order, the “first available blank invoice” referred to here refers to the blank invoice with the current invoicing order. For example, there are blank invoices from 1 to 100 on the invoicing terminal. When invoicing, you need to invoice in strict accordance with the order of 1~100, that is, first open the invoice No. 1, then open the invoice No. 2, and so on. Therefore, when the blank invoices No. 1~100 are not invoiced, the blank invoice No. 1 is the first available blank invoice for the invoicing terminal; when the blank invoice No. 1~10 has been invoiced, the blank invoice No. 11 is The first available blank invoice for the invoicing terminal.

Therefore, further, as shown in FIG. 2, the foregoing step 101 may specifically include:

201. Query the first blank invoice currently available on the target invoicing terminal recorded on the tax control system, and record it as the first invoice;

202. Query the invoice number segment of all blank invoices on the target invoicing terminal recorded on the tax control system, and record it as the first segment;

203. Query the invoice number segment where the first invoice is located in the invoice management system, and record it as the second segment;

204. Determine whether the first segment includes the second segment, and the first blank invoice in the second segment is the same as the first invoice, and if yes, perform step 205, if no Go to step 206;

205. Determine that a blank invoice available on the target invoicing terminal meets a preset invalidation rule of the tax control system;

206. Determine that the blank invoice available on the target invoicing terminal does not meet the preset invalidation rule of the tax control system.

For the above step 201, the invoice management system may invoke the “Query Current Unbilled Number” interface of the tax control system to query the first blank invoice currently available to the target invoicing terminal, and specifically query the invoice code of the blank invoice and/or Information such as the invoice number. Record this blank invoice as the first invoice C.

For the above step 202, the invoice management system may invoke the "purchase information inquiry" interface of the tax control system to query the invoice number segment of all the blank invoices on the target invoicing terminal, and record the invoice number segment of the inquiry as the first segment. B.

For the above step 203, it can be understood that in the invoice management system, all available blank invoices and the invoice number segments in which the blank invoices are located can be recorded in the invoice database. Therefore, the invoice number segment in which the first invoice is located in the invoice management system can be queried, that is, the second segment A. The second paragraph can be understood as a collection of blank invoices, recorded as the set A[A1, An].

For step 204, it is determined whether B contains A and A1 is the same as C. Among them, "B contains A" means that the blank invoice number segment A where C is located is included in all the blank invoice number segments of the billing terminal, and "A1 and C are the same" means that the current first unissued (available) The invoice C is in the first position of the A section. This condition is due to the mandatory provisions of the tax control system. When the tax control system is called to invalidate the blank invoice, only the blank unfilled blank invoice is allowed to be invalidated. For example, the invoicing terminal has a blank invoice of 1-100, where 1 is the first unfilled blank invoice, and the invoicing terminal can only start from 1 when invoicing, after 1 invoicing is completed (blue ticket or red ticket), Blank invoice 2 is used for the next invoicing, and so on. At this time, it is assumed that the paper invoice corresponding to the blank invoice 50 is damaged, for example, if it is bitten by the insect, the blank invoice (electronic invoice) of No. 50 needs to be invalidated in the invoicing terminal, but since only the blank invoice 2 is currently used, this If the interface of the tax control system is called to invalidate the blank invoice 50, it will not be allowed, and a failure or error message will be returned. Therefore, the invoicing terminal can only wait for the blank invoice of No. 2-49 to be used, and it is the turn of the current unopened blank invoice to be 50, in order to successfully call the interface of the tax control system to invalidate the blank invoice 50.

It can be seen that when the determination result in step 204 is YES, it indicates that the blank invoice available on the target invoicing terminal satisfies the preset invalidation rule of the tax control system, and step 205 is performed; otherwise, when the determination result in step 204 is no. When it is indicated that the blank invoice available on the target invoicing terminal does not satisfy the default invalidation rule of the tax control system, step 206 is performed.

102. Issue a prompt regarding not meeting the rule of default invalidation;

It can be understood that when the blank invoice available on the target invoicing terminal does not satisfy the preset invalidation rule of the tax control system, the invoice management system can prompt the user to invoice the invoice number segment of the target invoicing terminal and the blank invoice number of the tax control system. The segments do not match and cannot be invalidated.

103. Determine a target invoice number segment to be invalidated in a blank invoice available on the target invoicing terminal;

Specifically, after determining that the blank invoice available on the target invoicing terminal satisfies the default invalidation rule of the tax control system, the invoice management system may require the user to input the number m of blank invoices to be voided, where m≤n. After the user inputs m and clicks the "OK Obsolete" button, the invoice management system can determine the blank invoice set [A1, Am] on the target invoicing terminal as the above-mentioned target invoice number segment to be voided.

104. Invoke the tax control invalidation interface provided by the tax control system to the blank invoice in the target invoice number segment, until all the blank invoices in the target invoice number segment are invalidated;

105, each time the tax control invalidation interface is invoked, it is determined whether the return result of the tax control invalidation interface is received, and if so, the normal flow step is performed, and if not, step 106 is performed;

For the above steps 104 and 105, it should be noted that when the tax control invalidation interface is used to invalidate the blank invoice, at present, only one blank invoice can be invalidated for each call. That is to say, for 1~m blank invoices, only the tax control invalidation interface can be called one by one to be invalidated, and the previous blank invoice can be invalidated before the next blank invoice can be invalidated. In particular, in order to improve the security of the invalidated invoice operation, in this embodiment, when the tax control invalidation interface is first called, the user is required to input or confirm the tax control key. Wherein, the above-mentioned tax control key is a security component pre-allocated to the user for tax control operation, and the tax control key may be specifically a hardware module similar to an electronic cipher, and the hardware module is required when calling the tax control invalidation interface. The legal verification of the tax control invalidation interface can be made after legal verification. In addition, if the tax control invalidation interface is required to input the tax control key each time, the operation process becomes very cumbersome and inefficient, so in this embodiment, the tax is continuously called for the blank invoice in the target invoice number segment. When the control is used as the waste interface, in general, the user only needs to input the tax control key once. If a tax control invalidation interface is invoked, the return result of the tax control invalidation interface cannot be received, or the return result is received but the return result is invalid, the continuous call of the tax control invalidation interface can be interrupted. After the continuous call is interrupted, if you want to continue to call the tax control invalid interface for the blank invoice that has not been invalidated, you need to enter or confirm the tax control key again. In this regard, the embodiment is not specifically limited.

Understandably, in general, the success rate of calling the tax control invalidation interface is higher. Therefore, when the tax control invalidation interface is continuously called for the blank invoice in the target invoice number segment, all blank invoices can often be called through consecutive interfaces. Successfully invalidated. However, in order to avoid the situation mentioned in the background art, in this embodiment, each time the tax control invalidation interface is invoked, the invoice management system determines whether the return result of the tax control invalidation interface is received, and if a return result is received, Follow the normal process steps; otherwise, if no return results are received, then step 106 is performed.

Further, as shown in FIG. 3, the foregoing steps 104 and 105 may specifically include:

301, invoking a blank invoice in the target invoice number segment that is not invalidated, calling the tax control invalidation interface provided by the tax control system;

302, it is determined whether the return result of the tax control invalidation interface is received, if yes, step 303 is performed, and if not, step 106 is performed;

303, determining whether the received result is invalid or invalid, if the result of the return is invalid, starting from the current blank invoice, returning to step 301, if the result of the return is invalid, proceed to step 304;

304. Update the information that the current blank invoice has been invalidated to the blank invoice inventory of the invoice management system;

305, determining whether all the blank invoices in the target invoice number segment are invalidated, if not, returning to step 301, and if so, executing step 306;

306. End the invalidation operation of the target invoice number segment.

For the above step 301, the above-mentioned "first unfilled blank invoice" refers to the blank invoice currently invalidated in the target invoice number segment. For example, if the target invoice number segment is A1~Am, the above-mentioned “first unfilled blank invoice” refers to the blank invoice A1 when the tax invoice is invalidated. When the blank invoice A1 is invalidated, it is followed by blank. Invoice A2 becomes the “first unfilled blank invoice”; and so on, assuming that k(k<m) blank invoice has been invalidated in A1~Am, the blank invoice A(k+1) becomes the “ The first unfilled blank invoice."

For the above step 302, if the invoice management system receives the return result of the tax control invalidation interface, step 303 is executed to further determine whether the returned result is invalid or invalid.

For step 303, if the returned result is invalid, the current blank invoice is not completed. Among them, the current blank invoice refers to the blank invoice to be invalidated when the tax control invalidation interface is called. In order to ensure that the current blank invoice is voided, you can call the tax control obsolete interface again. In general, more than two tax control invalidation interfaces are called for the same blank invoice, and the success rate can be as high as 99.99%. Therefore, it is basically ensured that the current blank invoice is completed. On the other hand, if the returned result is invalid, then step 304 can be performed to update the blank invoice inventory on the invoice management system.

For step 304, when a blank invoice is invalidated, it indicates that the blank invoice is no longer available, so it needs to be deleted from the blank invoice inventory of the invoice management system, or in the blank invoice inventory of the invoice management system. Blank invoices are marked as obsolete.

For step 305, after each blank invoice is successfully invalidated, it is determined whether all blank invoices in the target invoice number segment are invalidated. If not, proceed to step 301 to invalidate the remaining blank invoices that are not invalidated. Otherwise, the end of the invalidation process, the blank processing method for blank invoice provided by the embodiment is completed.

106, by querying the invoice information table on the tax control system to determine whether the current blank invoice is invalid, if yes, proceed to step 107, and if not, proceed to step 108;

The current blank invoice refers to a blank invoice to be invalidated when the tax control invalidation interface is invoked, and the invoice information table records information about the success or failure of each blank invoice on the tax control system.

It can be understood that although the invoice management system may not receive the return result of the tax control invalidation interface due to various accident reasons, for the tax control system, the invoice information table records the success or failure of each blank invoice. Therefore, the invoice management system can query the invoice information table to know whether the current blank invoice is invalid. If the invalidation is successful, step 107 is performed; otherwise, if it is not invalid, step 108 is performed.

107, the current blank invoice has been invalidated information updated to the blank invoice inventory of the invoice management system, and from the next blank invoice of the current blank invoice, return to step 104;

If the current blank invoice is invalidated, the information that the current blank invoice has been invalidated may be updated to the blank invoice inventory of the invoice management system, that is, it is deleted from the blank invoice inventory of the invoice management system. Then, the invalidation operation is continued from the next blank invoice of the current blank invoice.

108. Starting from the current blank invoice, return to step 104.

If the current blank invoice is not invalidated, the tax control invalidation interface needs to be called again for the current blank invoice to ensure that the current blank invoice is invalidated. Therefore, the invalidation operation can be continued from the current blank invoice.

In this embodiment, the invoice information table can be inquired to know whether the current blank invoice is invalid, and then the corresponding processing is performed, which can ensure that the blank invoice of the target invoice number segment can be invalidated, and the blank of the invoice management system is ensured. The invoice inventory is consistent with that in the tax control system.

For ease of understanding, referring to FIG. 4, a blank processing method for blank invoices of the present application will be described in more detail below by another embodiment:

401. After determining the target invoicing terminal that needs to invalidate the blank invoice, determine whether the blank invoice available on the target invoicing terminal meets the default invalidation rule of the tax control system, and if yes, execute step 403, if no, execute step 402. ;

402. Issue a prompt regarding not meeting the preset invalidation rule;

403. Determine a target invoice number segment to be invalidated in a blank invoice available on the target invoicing terminal;

404. Modify, in the invoice management system, the preset flag information corresponding to the first blank invoice in the target invoice number segment to be abnormal;

405. Insert, into the invoice database of the invoice management system, the invoice related information that the first unfilled blank invoice is invalidated this time;

406. Call the tax control invalidation interface provided by the tax control system for the first blank invoice that is not invalidated;

407, it is determined whether the return result of the tax control invalidation interface is received, if yes, step 410 is performed, and if not, step 408 is performed;

408. Determine whether the current blank invoice is invalid by querying the invoice information table on the tax control system. If yes, execute step 409. If no, proceed from the current blank invoice to return to step 404.

409, the information that the current blank invoice has been invalidated to the blank invoice inventory of the invoice management system, and starting from the next blank invoice of the current blank invoice, returning to step 404;

Step 410, determining whether the received result is invalid or invalid, if the result of the return is invalid, then steps 411 and 412 are performed, if the result of the return is invalid, step 413 is performed;

411. Delete, from the invoice database, invoice related information that the current blank invoice is invalidated this time;

412, feedback information about the failure of the current blank invoice to the designated administrator, and starting from the current blank invoice, return to step 404;

413. Update the information that the current blank invoice has been invalidated to the blank invoice inventory of the invoice management system;

414. Modify the preset flag information corresponding to the current blank invoice to be normal;

415, determining whether all the blank invoices in the target invoice number segment are invalidated, if not, returning to step 404, and if so, executing step 416;

416. End the invalidation operation of the target invoice number segment.

In this embodiment, the contents of the foregoing steps 401 to 403, 406 to 410, 413, 415, and 416 are similar to those described in the previous embodiment, and details are not described herein again.

For the above steps 404 and 414, in order to facilitate the administrator of the invoice management system to maintain the system and check related abnormal errors, the embodiment may also add a relevant identifier in the process of performing the invalidation operation on the blank invoice. It can be understood that, by setting the identification information of the current blank invoice, and calling the tax control to invalidate the interface, the identification information is set to "abnormal", for example, set to 0, after the tax control is invalidated, if the tax control is If the result of the invalid interface is a failure, the current blank invoice always has an abnormal condition in the invalidation operation, so the relevant information can be fed back to the designated administrator to remind the designated administrator to perform related maintenance. When the administrator is designated for maintenance processing, the designated administrator can quickly locate the blank invoice location where the exception occurs by using the preset flag information of the blank invoice, thereby helping the designated administrator to check and handle the abnormal situation. When the return result of the tax control invalidation interface is successful, the preset flag information is modified to be normal, for example, set to "1", and the blank blank invoice which is normally invalidated can be distinguished from the blank invoice which is invalid.

For the above steps 405 and 411, the invoice management system may further insert the invoice related information of the first unfilled blank invoice into the invoice database of the invoice management system. If the return result of the tax control invalidation interface is received and the return result is invalidation, the invoice related information of the current blank invoice is invalidated from the invoice database. It can be understood that the above-mentioned invoice related information refers to basic information and/or detailed information related to the current blank invoice. The basic information may include the applicant of the invoice, the application department, the application date, the purchaser, the purchase date, the warehousing personnel, the warehousing time and the like; the detailed information may include the invoice type of the invoice, the invoice denomination, the invoice score, the invoice code, and the like. . Two different forms can be used in the invoice database to store the basic information and detailed information. If the return result of this tax control invalidation interface is invalid, it is not necessary to delete the invalid invoice related information, which will help the manager to query the invoice related information of each blank invoice that has been invalidated through these two forms, and Check it against the blank invoice inventory to verify that the data in the blank invoice inventory is accurate. If the return result of the tax control invalidation interface is invalidation, the invalidation cannot be considered to be valid, and thus the invoice related information of the current invalidation needs to be deleted from the invoice database.

For the above step 412, if the return result received after the tax control invalidation interface is invoked is invalid, the information about the invalidation of the current blank invoice may be fed back to the designated administrator, and the current blank invoice is started. Go back to step 404.

It should be understood that the size of the sequence of the steps in the above embodiments does not mean that the order of execution is performed. The order of execution of each process should be determined by its function and internal logic, and should not be construed as limiting the implementation process of the embodiments of the present application.

In addition, in the present application, in order to further ensure that the blank invoice inventory stored by the invoice management system is consistent with the tax control system, the blank invoice inventory stored in the invoice management system and the tax control system may be periodically (e.g., executed once an hour). The blank invoice inventory is synchronized, which is based on the blank invoice inventory in the tax control system. During the synchronous update process, the invoice management system can also find invoice data with deviations between the two blank invoices, and report the inconsistent invoice data to the designated administrator for subsequent maintenance and processing.

The above mainly describes a blank blank invoice processing method, and a blank blank invoice processing device will be described in detail below.
