Nearly every business is dependent on a constant flow of new accounts. It’s easy to ignore this because most businesses earn most of their revenue from old, established customers.
The problem is that a certain percentage of old customers will drift away or change their focus every year. They’ll change their buying habits, often for reasons that you can’t influence or life just happens.
So you need to continually market to recruit new customers, establish them, and start promoting them up your customer ladder, so that one day they’ll be part of your staple business clientele.
