Many people think that a sale ends when the customer walks out the
door. For some smaller-priced items, it does. I wouldn’t expect my
local convenience store to make a follow-up call to check if I was
satisfied with my purchase of a carton of milk. But for higher-priced
items and services, following up after a sale is a surefire way to
ensure that your customers are very satisfied with your level of
service. Even if the customer isn’t happy, at least you have the
chance to do something about it.
