When we just start a business, our goal is to get many customers. The more people that patronize us the more sales and profit we make. But is this really the case? We should know that a client that comes back for more product or service is better than 10 new ones that patronize once. When people patronize you, your aim should be to keep him and make him come again. The more you do this to people the better. Also these ones will also tell others about you. Now how do you get them to come back? Offer them an outstanding product or service. Stand out from your competitors, let them see that you are the best in your niche. So try your best to always improve in what you do. Just my little cents.
