A successful sales technique is the starting point of your success.
The key is understanding the needs of your client and to be sincere in communications with clients, so as to build a harmonious cooperative relationship. Any sales opportunity should be grasped, as these will help to improve your sales techniques.
Experts will provide advice to solutions for problems, whilst a friend with vast exposure can help you solve these problems.
The goal for you, being a sales personnel, is to establish a long-term cooperative relationship with your clients. As such, you should communicate with your clients like you would with a friend right from the beginning.
Clients will rely on the information you provide to make purchase decisions and they should be the experts in making that judgement. Your role, being a friend, is to provide the required information and to demonstrate your products and how they can benefit your clients.
补充第二段：
A successful sale does not come by chance. It is the result of learning, planning, a salesperson's knowledge and the application of that knowledge. Believing in your own product is essential to the success of your sales. The confidence which you have, will be passed on to your clients. If you have no faith in your products, neither would your clients. Instead of claiming that clients are convinced by the logics of your sales speech, it is far more correct to say that they are convinced by your confidence in the productes. Understand your clients' needs and fulfill those needs. Not knowing what the clinets want is like walking in the dark, efforts are wasted and objectives are not achieved. Then what is required by sales personnel to touch the hearts of your clients? The answer is simple. To convince any clients, at any place and at any point of time, there is only one true factor, and it is sincerity. It is not merely selling without helping. To sell is sales-oriented, whilst to help your client is customer-oriented, focusing on assiting your clients.
