How To Establish The Client's Or Customer's Needs When Selling To Them

How can I establish the client's or customer's needs?

It's very important that you establish the customer's needs, because you really can't start selling without it. You need to get the client talking and you need to listen. Because what you're trying to do is trying to match what you're able to sell, in the way of a product or service, to their needs. Don't try and sell people something that they don't want. For example, if you're trying to sell a space-saving gadget or something to somebody who's got plenty of space, don't bother, because they won't buy your product, and then you've lost your credibility.
