After the establishment of the toy store, the most fundamental issue that determines whether it can continue to operate is whether it can serve its customers well. In this regard, customer management and maintenance become particularly important. Customer management and maintenance focus on the long-term maintenance of the store. There is a saying: it's easy to start a store, but hard to maintain it. Some friends start their stores with great ambition, but after less than two months, they begin to lose heart. There are two reasons for this: one is that the preparatory work before opening the store was not done well, and the other is that the customer management work after opening the store was not done well.
