In recent years, the vigorous development of computer technology has changed the business model and competitive environment. It not only changing the way business transactions, but also affect the way collaboration between the companies. The enterprise purchase, inventory, sales of very large amount of information, data analysis is difficult, Purchase, Sales through the use of business-to-business information of the time, and accurate data, to a large extent, and thus be able to shorten the lead time in order to bring To stock, transport efficiency greatly improved. Any enterprise can be collected timely and accurate information needed in order to meet market demand, orders for customers, suppliers and enterprises to adjust production management in a timely manner to ensure the lowest cost businesses and the largest profit, which greatly promote yield Invoicing system users every need to maintain a strict standard, which is a Invoicing system, the quality of the customer's concern on major issues.Buying-stock-selling is based on logistics, the paper flow to the main line, the flow of funds to add to the three streams of data on the purchase, inventory, sales and financial management systems, which can reduce inventory and improve capital utilization and the rate of settlement To achieve efficient management, real-time, scientific and intelligent, is to improve the comprehensive competitiveness of enterprises an effective way.In this paper, through a chemical analysis of the demand for parts to Purchase, Sales and function of design, to develop a system of Purchase, Sales, the company's day-to-day operations and the handling of information in a comprehensive, systematic management. Throughout the development of the system, using software engineering theories, methods and related technology, and life-cycle system uses the structure of the design process in order to reach the stage of the development of the whole system (needs analysis, system design, testing system) and so on Runs through the course together.Buying-stock-selling for the software system, complex business processes to ensure that the system is the quality of the user's attention. Black Box Testing methods used in the system, based on the use of scenario-based method of testing and preparation of test cases. This method can accurately grasp of what the user needs to be done, from the user's task to find out what users do and how to do it. The completion of the module design and use case design of the test data. Improve the quality of the software on the user's confidence, to simplify the complexity of testing, so that users in different scenes can be normal operation.Based on this paper, the system of the main features of the technology and include: easy-to-use system for real-time information can be shared with personalized features, the realization of the legitimate users to share information, to meet the needs of different users; functional diversity From the time of admission documents to the inquiry, the summary, print statements, fully able to meet the needs of users; and to be able to guarantee data security.
