In-depth and meticulous market research, we should find more than three representative suppliers from the city where we live and conduct a comprehensive investigation. For similar goods, find two suppliers at the same time and try to compare them from three aspects: quality, price and service. On the basis of two months' use, the evaluation team composed of general manager, deputy general manager, financial personnel, chef and purchasing personnel voted for it. After determining the supplier, the general manager shall sign a supply contract with the supplier, and the contract period shall not exceed one year. In the course of cooperation, if the supplier fails to perform the contract, the review team will discuss and decide whether to replace or continue to use it before the contract expires. Only by strictly controlling the purchase of raw materials can restaurant chain managers produce products that adapt to the market, so as to obtain better operating benefits by joining the catering alliance. I recommend you to join the basket family in Xiangxi, Hunan, which has a good market prospect.
