Design And Implementation Of Freight Invoice Tax System

With the rapid development of the socialist market economy, the role of the invoice in the socio-economic activities growing. However, due to the dispersion of invoices, the tax department can not be a good use of invoice monitoring, resulting in a huge loss of national revenue. Freight invoice tax management system is proposed in order to solve this problem through the construction of the system, to achieve effective management of the business activities of taxpayers, the tax system to improve cargo transportation industry regulatory standards invoices, advance tax according to law, to curb tax evasion.By reading the literature on the research status of tax information management system to conduct a detailed analysis of the background and significance of research and topics discussed. In addition, through the technical literature study, to determine the target system selection ASP.NET technology, ADO.NET data access technology, C# development language, SQL Server database development. In the beginning of the development project, the first in-depth tax administration user needs research, in-depth exchanges and discussions freight invoice for the current tax administration issues exist in the work, summarize the system requirements, and the demand for conversion of specific documents, after determining the goal of building the system, complete the system of business processes, functional requirements, and analysis of non-functional requirements. In the overall system design work, mainly to complete the system network topology design, software architecture design, functional design, database design and security design, through system design, draw basic framework structure of the system as well as general functional architecture. In the system detailed design work, completed registration management module, ticketing information management module, tax data receiver module, query statistics module, the tax changes query module, tax disc disk write disk module transmission, detailed design process the data transfer module, give a specific program flow. In the system implementation and testing and validation work, the main function module is given the key code and run the interface and through functional testing and performance testing to verify the correctness of system implementation.By developing freight invoice tax management system, standardize the freight invoice operational processes, improve the quality of service to taxpayers, to prevent forgery, false, false start and transportation invoices, standardized freight invoice management, invoice for freight flows Tracking the whole process of certification for the freight invoice deductions, crosscheck and security check of the foundation.
