In order to get to the end result of a satisfied customer, you need to determine what want or need will be satisfied by the customer in receiving your product (tangible or intangible). This is really the basis since in my corporate experience, sole proprietorship will usually either over deliver too much and lose sight of the basic need or give to little to sustain the customer. The best tool to gage your customers is asking for feedback (use one of the free survey tools). Hopefully you can get some of the population to answer the survey to give you an accurate reading if you are under performing or if you are giving too much away. Finally, keeping your customer engage and remembering you when making their next purchase is important. Sending out reminders, new product information, thank yo
