The proposal for a high technology product often reads like a technical treatise. To move into the realm of a sales tool it should have a good cover letter that restates the key benefits of the product, specifically applied to the customer being addressed. In other words, it should have the value propositions prepared for that customer. Further, it should carry some closing statement(s) such as suggesting the time you’ll be in touch to discuss delivery and other final arrangements. It should be appealing, hard-hitting and straight-forward.
