 So, guideline to approach the various prospects regarding your initial sales, first, selling requires listening rather than hearing. The difference is understanding what the prospect says and being sensitive to his or her concerns and needs and jointly looking for a solution, because as we know that there is no product which is visible or which we can show, product is in the making, there is a concept. In order to make this concept into a real product, it is very important that we understand the requirement of the market. So, what the prospects, what the potential customer require, what are their problems with the solution which they are using at the moment, maybe efficiency, maybe wastage, maybe quality, maybe consumption of electricity. So, instead that you tell what you have upfront, it's much important that you understand what the prospect requires from a new product. Second, the sales message should focus on benefits rather than features or even better link features to benefits, the different features of your product, its size, dimensions, weight, what can it do, how this product can be beneficial to the prospect and how can you link up the product's benefits with the prospect's requirements and problems. This will help the prospect, understand the products as a means to an end, why your new product is a solution to the customer's problem. You need to link up the product being offered with the customer's problem, how can your product solve your problem.

Spin model explaining a little more is situation questions, first ask about the facts and the background, again facts about the process and how you have reached to this process. Problem questions, explore problems, difficulties and dissatisfaction, implication questions, third follow up on a customer's problem and explore its effects, finally ask questions that encourage the customer to tell you the benefits that your solution could offer, you use your product to this extent, your customer can convince you and link up your product, your machinery can help us in this particular way to solve these specific problems.
