I used to work for a sales account in a Australian Telecom Company. At first, it was not easy to learn how to sale without the clients knowing that we are really selling our product to them. We ask questions on how a specific product is being used everyday and ask about the benefits and the difficulties that they have encountered. After knowing their answers, we start to talk to them and make them see a better picture of what kind of convenience they could have with a specifc product without paying more, but having more quality and there I got the technique on how to close 30 sales a day. I hope I could share it to other people.
