Abstract

The invention provides an automatic invoicing method of a gas station trade, which provides a universal, open, efficient and automatic invoicing method for business system software of petroleum corporations, facilitating the business system software to access tax control register products in different brands realizing automatic invoicing through uniform and standard DLL interface documents by shielding the complicated physical communication characteristics of a computer and the terminal of the tax control register, and satisfying the functional requirements of the gas station for automatic invoicing business. A use method comprises the following steps: connecting the computer of the gas station with the tax control register through a serial cable, and calling an interface of dynamic link library (DLL) documents through a gas station information management system (business system software for short), realizing that the business system software is connected with the tax control registerto automatically invoice taxation control invoices after refueling by an hanging gun in the gas station and closing an account of sold commodities.

Description

technical field [0001] The invention relates to a tax control device, in particular to a method for automatic invoicing by a tax control machine in the gas station industry. Background technique [0002] At present, the business of selling oil products and commodities (non-oil products) at gas stations is handled by the corresponding internal information system, and when issuing invoices, gas stations need to purchase tax control machines to issue invoices according to the requirements of the competent tax authorities. Since the national standard of the tax control machine does not clearly stipulate a unified external information system communication interface, the information system of the gas station and the billing device of the tax control machine become an information island, and information sharing cannot be realized. When a gas station issues an invoice, the operator needs to manually enter the invoicing information on the tax control machine for the second time. Due ...
