Three steps in the customer satisfaction process:
1. Find out what your customers expect.
2. Meet these expectations.
3. Where possible, exceed these expectations.
If you can promote the fact that you offer 100% unconditional customer satisfaction guaranteed, there really is no risk to the customer. The weakness with this offer is building the credibility with your customers that it is a bona fide offer, not just a promise containing lots of small print that will result in them never being able to claim a refund because of a technicality (such as the complaint wasn't lodged on the first day following a full moon).
If you are really going to be committed to offering complete customer satisfaction you will reap great rewards, because there is no risk to your customers and as a result they will keep coming back to your business and recommending it to their friends. But, and it is a big 'but', your offer has to be genuine and real. Customers aren't stupid and they will see through hollow promises and shallow guarantees. Treat your customers with the respect that they deserve: when you make a satisfaction guaranteed offer, don't cheapen it with hidden catches.
Use the slogan in your advertising and on your flyers and, most importantly, believe in your product enough to offer this kind of guarantee.
If you have a good customer service system in place, complaints should be minimal. Even if they do occur, they will be handled and resolved quickly and professionally.
