I will write a value proposition for your product or service

The answer is a Value Proposition! Every marketing plan must emphasize it and this is the first thing that should be communicated to your buyers and investors. A value proposition summarizes reasons why your customers should buy your product and how the product solves their problem. A Value Proposition statement has to be easily understood. It can be written for one or more product lines. It should also list specific benefits of the product or service. A value proposition includes post purchase expectations – how the product solves customers' problems and how the product/service will perform?
