I read that to qualify a customer, a free trial of a product or a extremely low priced product should be offered and if someone makes a purchase, they have proven that they want to be your customer and are now worth your time. That doesn't sound right and I think that I maybe misunderstanding something. I understand asking potential customers questions or reading forums to determine what a customer wants and either providing the solution or pointing them in the right direction to find the solution if you know where it is but can't provide it. Shouldn't a seller prove that their product is exactly what someone wants and give them a reason to buy. I think that free trials are great and I have purchased a few in my time but I don't understand offering them to get someone to prove that they want to be your customer. Either a customer wants to buy or not, either you have what they want or not. I feel that it is the seller who has something to prove not the customer. Maybe I am looking at this from the wrong viewpoint and misunderstanding. Thanks in advance for the help.
