As shown in fig. 1, an embodiment of the present invention provides an automatic true-check and repeat-check method for an invoice, which may include the following steps:
step 101: for each invoice that has been submitted to a tax bureau for invoice reimbursement, storing values for at least two invoice information items for each invoice in an enterprise-internal database, wherein the at least two invoice information items comprise an invoice code and an invoice number;

step 105: and when the first invoice needs to be subjected to a duplicate checking process, inquiring whether the value of at least two invoice information items of a target invoice is stored in the internal enterprise database according to the first value and the second value, wherein the value of an invoice code of the target invoice is the same as the first value, and the value of an invoice number of the target invoice is the same as the second value, if so, executing a duplicate checking failure process to ensure that the first invoice cannot be reported to the tax bureau for invoice reimbursement.
The embodiment of the invention provides a method for automatically verifying truth and repeating weight of an invoice, which comprises the following steps: storing the values of a plurality of invoice information items of each invoice that have been reported to a tax bureau for invoice reimbursement; identifying an externally uploaded invoice to obtain the value of an invoice code and an invoice number of the invoice; when the invoice needs to be verified, the two values are sent to a tax bureau to send out an invoice verification request, and corresponding verification passing notification sent when the tax bureau passes the verification is received, otherwise, verification failure processing is executed according to the fact that the corresponding verification sent by the tax bureau does not pass the notification so that the corresponding verification can not be reported to the tax bureau for invoice reimbursement; and when the invoice needs to be checked for duplication, whether the values of a plurality of invoice information items of the invoice are stored or not is inquired according to the two values, the values of the invoice code and the invoice number are respectively the same as the two values, and if so, duplication checking failure processing is executed so that the invoice cannot be reported to a tax bureau for invoice reimbursement. According to the embodiment of the invention, the problem invoice can be prevented from being reported to a tax bureau through true check and repeat check of the invoice.
Considering that the combination of the invoice code and the invoice number can be used for distinguishing different invoices, and in the invoice identification, the identification accuracy of numbers and letters is superior to that of characters, so that the invoice verification and the invoice duplication verification can be realized based on the invoice code and the invoice number without combining other invoice information items of the invoice, such as invoice invoicing date, tax sum and the like.
In the embodiment of the invention, when the invoice needs to be verified, the invoice platform can be combined with an external tax bureau system to verify the authenticity of the invoice, and false invoices which fail to pass the verification cannot be used for invoice reimbursement.
For example, the invoice verification process can be implemented by an invoice verification service of a tax bureau. Specifically, the invoice platform of the enterprise can send the value of the identified invoice code and the value of the invoice number to the tax bureau in a data flow mode. If the invoice is true, in the invoicing stage, the tax bureau invoices the invoice and records the corresponding invoicing record, for example, the value of each invoice information item of each invoiced invoice can be recorded. Thus, the tax bureau can search whether the invoice issuing record of the corresponding invoice is available according to the received value of the invoice code and the received value of the invoice number, if so, the invoice is considered to be true, otherwise, the invoice is false. After the tax bureau checks the invoice, the corresponding checking result can be fed back to the corresponding invoice platform.
In the embodiment of the invention, when the invoice does not pass the verification, the invoice platform can execute the verification failure treatment, for example, false invoices can be respectively or intensively displayed so as to be convenient for a manager to check and treat. For example, after the administrator checks the false invoice reminder, the administrator can manually confirm whether the false invoice is correctly determined again, and if the false invoice is correctly determined, the false invoice can be rejected.
In the embodiment of the invention, when the invoice needs to be checked for duplication, the invoice platform can be combined with an internal database of an enterprise to check the repeatability of the invoice, and the duplicate invoices which fail to pass the check cannot be used for invoice reimbursement. In detail, in the step 105, if the determination result is negative, it may be determined that the first invoice is not a duplicate invoice.
In the embodiment of the present invention, each invoice that has been used for invoice reimbursement may be stored in the internal database of the enterprise, and in general, the invoice may be stored by storing a value of an invoice information item of the invoice, and at least a value of an invoice code and a value of an invoice number of each invoice need to be stored. Therefore, when the invoice is verified to be duplicated, whether the corresponding invoice is duplicated or not can be determined by inquiring each invoice stored in the internal database of the enterprise according to the value of the identified invoice code and the value of the invoice number, and the duplicate verification failure processing can be executed when the duplicate verification is failed. For example, duplicate invoices may be displayed separately or collectively for convenient viewing and processing by an administrator. For example, after the administrator checks the prompt of the duplicate invoice, the administrator can manually confirm whether the judgment of the duplicate invoice is correct again, and if the judgment is correct, the duplicate invoice can be rejected.
In the embodiment of the invention, the invoice database usually comprises more invoices, so the value of the invoice code and the value of the invoice number can be used as the index field, and the repeated invoice can be quickly checked by the technical means of establishing the index, thereby realizing the efficient checking of the repeated invoices.
The embodiment of the invention performs the verification and the duplication checking on the invoice, so that only the invoice passing the verification and the duplication checking can be used for invoice reimbursement. Thus, invoices which fail to pass the verification can be free from the verification, or invoices which fail to pass the verification can be free from the verification.
In summary, in the embodiment of the present invention, when the user uploads the invoice in the reimbursement process, the invoice platform may collect the invoice code and the invoice number of the invoice, and check the authenticity of the invoice uploaded by the user through the connected tax bureau system, and refuse to receive the invoice for the invoice that fails to be checked. And the collected invoice codes and invoice numbers can be used as comparison fields to search whether the same invoices exist in the invoice database, and if the same invoices exist in the invoice database, the invoice is rejected.
In one embodiment of the present invention, the method may further comprise: receiving and storing the value of at least one other invoice information item of the first invoice sent by the tax bureau when the first invoice passes the verification of the tax bureau; and performing statistical analysis on the invoice big data according to the stored invoice codes and invoice numbers of the invoices and the values of other invoice information items.
For example, the invoice platform may implement the definition of different types of tax risk indicators through a configuration mode based on a plurality of data sources such as accounting documents, subject balances, financial statements, invoices, tax payment statements, and the like, for example, the indicator types may be divided into a numerical indicator, a comparison indicator, and a screening indicator.
The output result of the numerical index is the sum or the ratio, and different risk levels can be defined by the system according to the deviation degree of the threshold value by setting the threshold value.
For the comparison index, data generated by a plurality of data sources can be compared, and when the comparison logic is not met, the system can automatically judge as a risk.
For the screening indexes, screening conditions can be set according to keywords and the like for vouchers, invoices and the like, and if conditions are set, the system automatically judges that risks exist.
As mentioned above, after invoicing by the tax bureau, the value of each invoice information item of each invoiced invoice can be recorded. Because each invoice platform identifies the value of the invoice code and the value of the invoice number for realizing invoice verification, the values of other recorded invoice information items can be provided for the corresponding invoice platform when the invoice verification passes. Considering that the invoices used for the invoice big data statistical analysis processing are all real invoices, the invoice platform only needs to identify the value of an invoice code and the value of an invoice number, and the tax bureau returns the values of other invoice information items when the invoice passes the verification. The operation not only can simplify the invoice identification process of the invoice platform, but also can ensure the accuracy of the value of the used invoice information item.
In the practical application of invoice reimbursement, after a user submits an electronic invoice to request for reimbursement of the invoice, the invoice is easy to be forgotten to be deleted, and the same invoice is stored in multiple places, so that the possibility that the invoice submitted by the user is a duplicate invoice is high. Based on the above, in order to reduce the data processing amount of the invoice truth verification, the invoice submitted by the user can be verified a priori.
Based on this, in an embodiment of the present invention, when the first invoice needs to be verified and reprocessed, the method includes: upon receipt of the first invoice;
the method may further comprise: when the values of at least two invoice information items of the target invoice are not stored in the internal enterprise database, storing the first value and the second value into the internal enterprise database; when the values of at least two invoice information items of the target invoice stored in the internal database of the enterprise are inquired, determining that the first invoice does not need to be subjected to true verification processing;
when the first invoice needs to be subjected to verification processing, the method comprises the following steps: when the first invoice check passes.
In the embodiment of the invention, for the invoices submitted by the user, the invoice platform executes invoice verification and reiteration processing according to the invoices stored in the internal database of the enterprise, and then invokes a corresponding verification interface of the tax bureau system to execute invoice verification processing after the invoice verification and reiteration pass. When the invoice is failed to be verified, the corresponding invoice does not need to be verified, so that the calling of a tax office interface can be correspondingly reduced, the corresponding data processing amount of an invoice platform and a tax office system is reduced, and the implementation mode is particularly suitable for application scenes that a user can easily submit repeated invoices.
Of course, because embodiments of the present invention are a priori true posterior heavy, invoices stored in the enterprise internal database are not duplicate invoices, but are still likely to be false invoices. The invoice platform checks the truth of the invoice after the invoice passes the duplicate check, if the truth check fails, the corresponding invoice can be marked as a false invoice or stored in a specific folder, so that the invoice used for invoice reimbursement and the unrepeated but false invoice are respectively stored.
In one embodiment of the present invention, to illustrate one possible implementation of invoice identification, the first invoice includes: the paper invoice corresponds to an equal-proportion image or an electronic invoice;
the method further comprises the following steps: determining two diagonal point coordinates of the first identification area;
wherein the first identification area is rectangular;
the first identification area comprises an area where the value of the invoice code is located in the invoice, and the first identification area does not comprise areas where the values of other invoice information items are located in the invoice;
in the two diagonal coordinates, the abscissa value of one diagonal coordinate is aX, the ordinate value is bY, the abscissa value of the other diagonal coordinate is cX, and the ordinate value is dY;
the method comprises the following steps that X is the transverse length of any preset rectangular frame of an invoice, Y is the longitudinal length of the preset rectangular frame of the invoice, a, b, c and d are preset constants corresponding to the preset rectangular frame, and coordinates of any diagonal point of the preset rectangular frame of the invoice are original coordinates;
the identifying the first invoice to obtain the first value comprises:
identifying a first transverse length and a first longitudinal length of the preset rectangular box of the first invoice;
determining two first diagonal point coordinates of the first identification area of the first invoice according to the first transverse length and the first longitudinal length;
determining the first identification area of the first invoice according to a preset origin coordinate and the two first diagonal point coordinates;
identifying a value within the first identification area of the first invoice using a pre-installed text recognition tool, and determining the identified value as the first value.
In the embodiment of the invention, the invoice handed over by the user can be an electronic invoice, and also can be an equal-proportion image corresponding to a paper invoice, such as a scanned part, a photo and the like of the invoice.
Typically, the zoom level may be different for different invoices. According to the embodiment of the invention, by setting the identification range of the invoice information item, the invoice information can be accurately identified for each invoice with different zoom levels, and the invoice does not need to be adjusted in zoom level.
Referring to fig. 2, fig. 2 is a schematic diagram of an invoice, which may generally include invoice information items and values thereof, such as an invoice code, an invoice number, an invoice date, a check code, a machine number, a name of a purchaser, a taxpayer identification number of the purchaser, an address and a telephone of the purchaser, a billing line and an account number of the purchaser, a name of a seller, a taxpayer identification number of the seller, an address and a telephone of the seller, and a billing line and an account number of the seller. These invoice information items and their values are typically fixed in the region of the invoice.
Based on this, to recognize the value of the invoice code, two diagonal point coordinates of the above-described first recognition area may be set, such as (aX, bY) and (cX, dY) shown in fig. 2, respectively. For the invoice shown in fig. 2, its corresponding first identification area may be as shown by the dashed box shown in fig. 2. a. The values of b, c and d are related to the selection of the preset rectangular frame and the origin coordinate, when the selection of the preset rectangular frame and the origin coordinate (0,0) is changed, the values of a, b, c and d are correspondingly changed, so that a first identification area determined by the two pairs of corner coordinates always corresponds to the value of the invoice code, namely when the system identifies the first identification area, the identified value is the value of the invoice code under the condition of ensuring the identification accuracy.
As shown in fig. 2, the invoice includes a plurality of rectangular frames, and the preset rectangular frame may be any one of the plurality of rectangular frames. For example, the preset rectangular frame may be a maximum rectangular frame included in the invoice, and the origin coordinate may be a vertex at a lower left corner of the maximum rectangular frame.
In the embodiment of the invention, under the condition that the preset rectangular frame and the origin coordinates are determined, a, b, c and d can be correspondingly set according to the position relationship between the preset rectangular frame and the origin coordinates and the region of the invoice code value in the invoice. Therefore, for any invoice with a zoom level, the first identification area can be accurately determined according to the transverse length and the longitudinal length of the preset rectangular frame of the invoice at the current zoom level, so that the value in the first identification area is identified and used as the value of the invoice code of the invoice.
In summary, the embodiment of the invention can effectively identify the value of the invoice code of the invoice. Based on the same implementation principle, the values of other invoice information items of the invoice, such as the value of the invoice number, can also be identified.
In one embodiment of the invention, the method further comprises:
a1: executing A2 when receiving an invoice issuing request sent by any external service system, wherein the invoice issuing request carries a first service detail of a first service transaction, and the current issuing state of the first service transaction is non-issuing;
a2: determining corresponding first invoice detail according to each invoice information item required by the preset invoice issuing and in combination with the first service detail;
a3: sending the first invoice detail to the tax bureau through a tax control server of the enterprise, so that the tax bureau makes a corresponding invoice according to the first invoice detail and receives a second invoice which is returned by the tax bureau and corresponds to the first invoice detail;
a4: providing the second invoice to a consumer of the first business transaction;
a5: sending a notification that the first service transaction invoicing is successful to the service system so that the service system records the invoicing state of the first service transaction as invoiced;
a6: and when the business money of the first business transaction is confirmed to be posted, carrying out verification and cancellation processing on the second invoice according to a preset invoice verification and cancellation flow specified by the business type of the first business transaction.
In detail, the invoicing scene can be invoicing according to a receipt, invoicing according to income and invoicing in advance.
Wherein for invoicing according to a receipt:
the client makes out an invoice after making a payment, which may be an receivable, such as payment of a common meter of a civil user, firstly checks the meter to confirm income, then pays the money and makes an invoice according to the payment record of the client; it is also possible to charge a prepaid fee, such as a magnetic card meter, to bill for the amount charged, and to transfer the income at the end of the month.
Wherein, for invoicing according to income:
invoicing is carried out after the income is confirmed, for example, a general meter of a large industrial and commercial company can bill a customer when the income is confirmed by meter reading, and the customer receives money after a certain accounting period; other goods sold on the market can be billed for confirming income, and the return is managed through the account age of the receivable account.
Wherein for advance invoicing:
if the income confirmation condition is not met, the client requires to pay after making out the invoice; or the sale of integrally connected gas appliances, there is also an advance invoicing.
Based on this, in one embodiment of the present invention, the service type of the first service transaction includes: any one of invoicing after the service money of the service transaction has been received, invoicing after the service money of the service transaction has been determined, and invoicing after the service money specified by the consumer of the service transaction has been determined.
For example, business systems such as ERP (Enterprise Resource Planning), all-purpose card, sales management platform, and the like, and an invoice platform may be modified, so that each business system can be better interfaced with the invoice platform, and different invoice reimbursement processes are specified for different types of business. According to the time point of issuing the invoice and the time point of generating the service, the invoice and the service can be matched one by one no matter the invoice is issued first or the service is generated first, and finally the purposes of preventing repeated invoicing, staggering the invoice and falsely issuing the invoice are achieved.
In detail, since the invoicing time points of different service types are usually different from the service carriers, the service system can mark whether each service transaction is invoiced or not, and the invoicing identification ensures that each service cannot be invoiced repeatedly.
In detail, because the invoicing data is directly generated by the service system, the consistency and the accuracy of the invoices and the source service can be ensured. For the business transaction needing manual invoicing, the invoice data can be matched with the business transaction data in a post-transaction verification and cancellation mode.
In detail, considering that partial services must be invoiced in advance, the service system can record and monitor through an invoice verification and cancellation ledger, ensure that each invoice must be verified and cancelled through post verification and cancellation, and perform key monitoring on invoiced and unchecked data.
In summary, in the embodiment of the present invention, the invoices correspond to the services one to one, so that the situations of repeated invoicing, invoice staggering and false invoicing can be prevented. Based on the wide application of the technology, the occurrence of the problem invoices, false invoices and repeated invoices can be reduced, so that the invoice data processing amount of an invoice platform is reduced, and the workload of an invoice issuing administrator is reduced.
In addition, for business transactions without business system support, the business documents cannot be checked and sold generally, but the corresponding accounting documents can be selected for checking and selling through the invoices on the invoice platform. The business transaction can include real estate leasing income, fixed asset disposal income, labor income, pipe network first-aid repair income and the like, and the business does not have a business system and the income is confirmed in a manual accounting mode. Most businesses can invoice after receiving money, and there are cases where invoices are issued first and not invoiced.
Based on the above, in an embodiment of the present invention, the method may further include:
s1: when a red punching cancellation request aiming at the second invoice is received, determining the current date, wherein the red punching cancellation request carries new service details of the first service transaction;
s2: determining a date of issuance of the second invoice;
s3: judging whether the issuing date and the current date are in the same month or not, if so, invalidating the second invoice and executing S5, otherwise, executing S4;
s4: triggering, by the tax control server, the tax bureau to issue a red invoice corresponding to the second invoice, wherein a sum of an amount of money of the red invoice and an amount of money of the second invoice is 0, and performing S5;
s5: taking the new service detail as a first service detail, and executing the A2: and determining corresponding first invoice detail according to each invoice information item required by the preset invoice issuing and in combination with the first service detail.
In an embodiment of the present invention, in the above S3, after the second invoice is invalidated, the service system may be further triggered to record that the invoicing status of the first service transaction is invalidated; in the above S4, after triggering the tax bureau to issue the red invoice corresponding to the second invoice, the service system may be further triggered to record the invoicing status of the first service transaction as being decremented.
For example, when the information of the amount, the title, etc. of the issued invoice is wrong, the business personnel can perform red flushing processing on the issued invoice through the invoice platform. When the invoice to be invalidated is an invoice issued in this month, the invoice to be invalidated can be invalidated and then the corresponding invoice is issued again based on the service detail in the red flushing invalidation request. If the invoice to be invalidated is not the invoice issued in the current month, a red invoice which is opposite to the invoice to be invalidated in amount and has the same other information with the invoice to be invalidated can be issued, the amount issued by the invoice to be invalidated is deducted through the red invoice, for example, the invoice issuing amount of the invoice to be invalidated is 5000 yuan, the amount issued by the red invoice is-5000 yuan, so that the sum of the amount of the invoice to be invalidated and the amount of the invoice to be invalidated is 0, and then the invoice is issued again based on the service detail in the red invoice invalidation request.
