For a customer, if he already knows how to choose a product, then how should we promote our product?

How customers know to choose a product is a false proposition. From the perspective of customer needs, many customers themselves cannot tell what their real needs are. Even if it is clear, what are the reasons why customers choose? Does the product you promote have the competitiveness to make customers choose again?

For example: A customer tells you that we have a supplier we cooperate with, and their products work very well. The first thing you should do at this time is not to continue talking about your products, but to sincerely ask customers for advice by asking questions. Can you tell me about the products you are currently using and how you cooperate? Maybe I can offer you something you didn't expect.

In short, you should not rely on your own assumptions to understand the customer's words. Use more questions and guidance to analyze the customer's intentions, so as to find key breakthroughs.
