Through the analysis of the non functional requirements of the system, the design of network hardware, software and security architecture of the system is defined. And in the non functional and functional requirements analysis, as well as the structure design for the foundation, in the system design part, further uses the database diagram and the class diagram, the system database and the function module has carried on the detailed design. In order to realize the system non functional requirements, the user interface of the system is designed in detail, and the detailed implementation method is given in this paper. Through the analysis of the business of the comprehensive management system of the VAT invoice, the system test method and the typical test cases are determined, and the final test of the whole system is completed.
