advantages: reducing costs and attracting customers; Disadvantages: platform dependence and low customer conversion rate.

1. Cost reduction: According to the code scanning ordering applet, customers can order and pay by themselves on WeChat, without waiting in long lines, thus saving cashier time, shortening service time and improving order rate.

2. Attracting customers: Make our own catering applet. If the customer information belongs to our own service platform, the customer data information can be freely inquired, and the exclusive coupons of the applet can be issued to attract customers and guide consumption.

3. Platform dependence: Depending on platforms such as WeChat, it is sometimes controlled by platform policies and cannot become an independent traffic portal.

4. The customer conversion rate is low: there are many customers of catering applet, which is easy to attract customers from outside the business circle to visit the store, and there are not many loyal customers in the business circle.
