The best way to measure the customers sactisfaction is to do some kind of consummer study where your KPÌ´s can be the "repetition of the purchase" during some period; you will also measure the fidelity for the brand and produt.

There are several ways to gather input from customers. The simplest way to find out how customers feel and what they want is to ask them. If you have only customers, you can talk to each one personally. The advantage of this approach is that you’ll get a personal “feel” for each customer.

Advisory boards are a much underused way to improve customer service, develop new services, and encourage repeat business. Even the smallest businesses can use them effectively.
