I am a salesman selling equipment. How do I know if the customer needs it by phone?

Clients don't usually have time to listen to you. You might as well explain the situation directly. First of all, you should know the customer, his characteristics, his situation and needs deeply. For example, if you want to sell a skin care product, you must first understand what kind of skin he is and what kind of products are suitable for him. What product is he using now, will he change it frequently and so on.

Another thing is that when you follow up with customers, don't rush to sell your products. First, let him feel that you know your products and industries very well. If he is confused in this respect, he can find you to solve it. If he asks a question and you can't answer it, will he still trust you to buy your product? Follow-up records and the like should be sorted out, and it is best to use software such as writing to manage customer information and follow-up records.
