It is true that most people like to give their business to companies they like and trust. If you provide a good experience to your clients odds are they will come back the next time. This is a good thing to know, but never assume that your customers will automatically come back to you.
There are lots of reasons why a customer may choose to give their business to someone else. Perhaps the other company has lower prices, has opened a closer storefront or is offering better services. Remember that on average, repeat clients will spend about 33% more money at your business than a new customer will.
