It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
As shown in fig. 1, a method for automatically verifying invoice authenticity includes:
s1, downloading the enterprise invoice information from the tax system to a local database; the invoice information includes invoice code, invoice number, invoicing date, invoicing amount (without tax), invoicing enterprise, etc.
S2, initiating an invoice checking request; the inspection request includes part of the invoice information, and in this embodiment, only the invoice code is included.
And S3, performing invoice query in the local database according to the invoice checking request and returning a query result. Comparing the invoice codes carried in the invoice checking request with the invoice codes in the local database one by one, wherein if the invoice information containing the invoice codes is inquired in the local database, the invoice is true, and otherwise, the invoice is false. If the invoice checking request carries the invoice code, the invoice number and the invoicing date, the invoice code can be used for inquiring when the invoice checking request is inquired in the local database, then the invoice number and the invoicing date are compared, and if all the fields are the same, the invoice is true, otherwise, the invoice is false.
According to the invention, the enterprise invoice information is downloaded to the local from the tax system in advance, and only the inquiry is needed in the local database when the invoice is checked, and the connection relation with the tax system is not needed, so that the coupling with the tax system is reduced; because the bill information in the local database is only the bill information of the enterprise, the data total amount in the invoice inspection is greatly reduced, and the inspection efficiency can be effectively improved compared with the bill inspection in a tax system; in addition, the service and the request can be positioned in the same network environment when the query is carried out in the local database, so that the response time of the system can be reduced, and the checking efficiency is improved.
