"Just" is an important word in OP The order of a sales pitch should be like this: * here is the problem we wre trying to solve. Is this your problem, mrs. Customer? * here is how our other customers were trying to solve the problem before they met us. Is this you, Mrs. Customer? * here are the benefits of our product. If we could do all of this, would you want this product? If you haven't moved them to a place where this hypothesis is true (if yes, then buy), no product demo in the world will help. Then yes, by all means prove you can deliver what you say.
