Let's talk about retail first: the goods are supplied by manufacturers and agents, and the required brands and products are selectively formulated by delegated procurement. According to the characteristics of the retail industry, determine whether the goods are on the shelves. If you need to enter the store, you can inform the manufacturer and coordinate whether it is borne by the manufacturer or agent (in fact, most supermarket promotions and advertisements and promoters are also borne by the manufacturer or agent); Unified management of employees within the retail industry, dressing the, all departments to carry out relevant training.

restaurant chain: it may require an initial fee, and the goods or semi-finished products will be supplied by the unified distribution of the headquarters, sent to the company headquarters or distribution center by the unified order management system, and the company will conduct unified promotion and promotion training. Unified time and cycle ordering (referring to well-known restaurant chains such as KFC); Uniform dress, uniform training and uniform management.
