There are many income opportunities to be mined with your existing customer base. This source can easily be overlooked in your pursuit of new profits, new customers and new income opportunities. Put yourself in the role of a customer. If you bought a product or service from a particular person and he answered patiently your every question, would you buy from him again in the future? Definitely. When a customer has given you his money, that’s not the end of the affair because by keeping in touch with him and developing a flourishing relationship with him, you will have a lifetime source of income opportunities. Imagine if 100, 1000 or even 10000 customers are waiting to grab your newest products or services even before they are released! Hence, it’s vital to build a customer base because not only does it save a lot of time and effort, it also increases your income opportunities.
