The invention relates to the technical field of bill management, in particular to a retail terminal
invoice co-
processing method based on multi-
service provider interface integration. According to the retail terminal
invoice co-
processing method based on multi-
service provider interface integration, a retail terminal completes collection of consignment data, and an operator initiates a service charge settlement process after
data verification is passed; after the store manager audits the consignment data, the dealer issues a value-added tax special
invoice, generates an OFD format file through the tax UKey, and uploads the OFD format file to the
system; the retail terminal extracts the invoice structured data, verifies the consignment data and the invoice data online, and confirms settlement after confirming that the consignment data and the invoice data are correct; and after the third-party financial
system obtains the data, the service fee is settled to the dealer. The retail terminal invoice co-
processing method based on multi-
service provider interface integration is high in adaptability, human input is reduced, data errors caused by manual input errors are greatly reduced, the
business data accuracy is improved, and the
business efficiency is improved.
