With the continuous improvement of the industry network construction level, a series of scientific and technological products representing modern science and technology are constantly introduced, including terminal POS machines that have just been put into use. How should account managers effectively manage this modern technology product? The author believes that account managers should start from the following aspects. 1, strengthen study, and fully master the skills and knowledge of using terminal POS machines. The terminal POS machine is a new electronic product for the industry, and the account manager is relatively unfamiliar. But as an account manager, he is responsible for promotion and use. Therefore, account managers should stand on their own feet, strengthen their study, fully grasp the functions and skills of terminal POS machines, and lay a good foundation for the next stage of promotion. 2. Strengthen publicity to arouse customers' sufficient attention to the use of terminal POS machines. Terminal POS machines are used by fixed-point households in the early stage, and the scope is relatively small, the influence is not enough, and the use time is short, and the functions are not fully reflected. It is easy for customers to ignore its existence value, which leads to low customer enthusiasm. This is because customers lack attention. Therefore, account managers should actively publicize the introduction of terminal POS machines, and start with the use, function, significance and benefits, and explain them to retail customers in detail, focusing on the benefits of actively using terminal POS machines, that is, excellent terminal retailers can get labor subsidies every month and occasionally tilt the tight supply, thus attracting customers' attention and improving their enthusiasm for use. 3. Do a good job in customer training, and adopt a combination of classroom explanation and field exercise. The terminal POS machine has many functions, and the acceptance ability of customers with limited education is low. It takes customers a long time and energy to truly operate independently. In order to make customers put into use more quickly and effectively, it is our first choice to take targeted training. In this regard, the account manager should take the service department as the training point in the early stage, call the terminal POS users for training, and let the customers master the operation skills and operate independently in a short time through classroom PPT demonstration combined with on-site simulation exercise. 4, do a good job in using tracking, irregular return visit guidance. Because the terminal POS machine has been used for a short time, customers are prone to abnormal use in the process of independent operation, such as a small number of bills per month or a large number of bills per day, which leads to the terminal POS machine data can not truly reflect the customer's sales situation that day. In this regard, account managers should strengthen the guidance and tracking of the use of terminal POS machines, focusing on guiding customers to inquire about the purchase, sale and storage of terminal POS cigarettes in real time during the sales invoicing process, grasp the sales dynamics of cigarettes in time, formulate reasonable cigarette order quantity and turnover, and reduce the phenomenon of blind inventory; Strengthen tracking, through the terminal analysis and application function of commercial system, track the usage of customer terminal POS machines every day, track the number of bill transactions of terminal POS machines every week, fill in the tracking table of terminal POS machine usage, and make irregular return visits to ensure the normal and effective use of terminal POS machines.
