System application of point-of-sale information system

The function of the earliest POS system was mainly to provide a quick checkout method by using bar codes, so as to reduce the mistakes caused by the manual entry of commodity prices by shop assistants. The POS system can quickly count the sales of goods through the computer, and combined with the electronic ordering system, it can quickly provide the sales status and inventory status of various goods of manufacturers, and even provide the analysis of purchasing behavior of different customer groups, so that manufacturers can understand the consumption tendency of customers more efficiently, effectively eliminate unsalable goods, and provide reference for future commodity development.

For convenience store operators in Japan, managers can easily know the daily or even hourly sales of various goods in the past through POS system, and even know the inventory quantity of goods in the store without actually counting the quantity. The POS system is even combined with the weather forecast, and it also provides the latest information of various commodities from the company headquarters. Managers can get these figures through handheld devices or computers, analyze and predict the possible future sales, and use them as a reference for ordering, which can reduce unnecessary inventory pressure and effectively grasp customer trends. At the same time, customer consumption information collected by POS system can be combined with customer relationship management system (CRM) to further realize one-to-one sales service.

Due to the diversification of system functions, in addition to retailers, the general catering industry and even hotel operators have introduced and used the system.
