Nobody likes to ask for trouble, but we need to gather feedback from our customers if we ever expect to serve them in a way which gains us a reputation for quality customer service. This won't be as uncomfortable if we have talk to the customer before, during and after the sale. The key here is to communicate. If we are talking about a major purchase, someone from your business, other than the sales person, should talk to the customer immediately after the transaction. Keep in mind that we are very familiar with the ins and outs of our business but the customer doesn't always know what to expect.
Every industry is different, but lets take the carpet industry for example.
The customers here might only buy carpet once every 10 or 15 years. They don't know what to expect. These are just a few questions that can come up between the time of purchase and the installation. She first talks to the customer about the expected delivery date and she lets them know she is going to be in touch again before installation. Later, just before installation, Joyce calls again, arranges the installation and answers questions.
