How to respond positively to customers?

In the face of customers who have already bought, at this time, the shopping guide should especially follow or boldly guide the customer's thinking and help the customer make a decision to make a deal. For example, a shopping guide can use this technique: "Elder sister, I will give you an invoice. I can sign the invoice for this machine and come to me if you are not satisfied. " In fact, customers are basically satisfied when they take a fancy to you, and they are looking for you for some small special reasons. But this can enhance customers' trust in products, shorten the consideration process and expand product sales opportunities. When taking the initiative, the shopping guide must be sensitive, diligent, familiar with the business, skilled, properly arranged, balanced and leave no flaws.
