Buy a foreshadowing for the next contact. Sales should be good at finding reasons to interact with customers. For example, when a customer comes to the exhibition hall, the salesman should consciously leave one or two questions that the customer can't answer, and then record them in the notebook. When the customer leaves the store, he will call again and directly tell the customer to call him, so as to answer the questions left by his last visit to the store.
Such telephone customers are not only willing to answer, but also feel that the salesman is very careful. Fourth, send text messages to customers first. Many calls are made directly to customers, and customers are unwilling to answer them without justifiable reasons.
