A pre-requisite to getting more customers is keeping the old one happy

Most people do not understand that getting more customers is dependent on how many customers you have lost or how happy or unhappy your existing customers are. Most people who want to buy a big ticket item like real estate will try to get the opinion of a friend, relative or colleague who has bought and used the product before. If the experience has been a negative one, the dissatisfied customer with dissuade the new prospective customer from buying the product and you will lose the sale. On the other hand, if the existing customer is happy, he will speak positively about your product and the sale is certain.
