The customer base is the group of customers who repeatedly purchase the goods or services of a business. These customers are a main source of revenue for a company. The customer base may be considered the business's target market, where customer behaviors are well understood through market research or past experience. Relying on a customer base can make growth and innovation difficult.
Companies with a customer base consisting mainly of large companies may increase their customer base by pursuing small and mid-size companies.
All businesses begin with no customers. These start-ups begin with an abstract idea that slowly evolves into something someone will buy. As these products evolve from abstract ideas into primitive objects that are then further refined, the business that created the product begins to gain customers. The satisfied customers become the repeat buyers and core customer of the company. This is the process that creates the customer base. Most often, successful start-ups begin with low-end or downmarket customers with low income and low costs. As the products or services that are being bought are polished and remade, a company gains higher-end customers who gain interest in the product as it reaches higher levels of functionality, use, or value. As the shift to these higher priority customers continue, they begin to be a larger source of income for the company, and slowly become the main base whom the business lends the most importance. This process, of moving from low-end customers to more expensive and more profitable customers, is known as upstreaming, and is an integral part of the theory of disruptive innovation.
Businesses work very competitively to keep their core market intact. The sellers will research their buyers to increase customer awareness. Keeping products customer oriented has become so huge a priority, in fact, that it has become a large focus of business schools to teach all types of business administrators, from manager to marketer, to keeping the customer in mind for the improvement and creation of sellable products. It is very rare for an established company to lose its core customers to incumbents, and it has been stated that when an established company loses their consumer base via sudden and straightforward methods, it was not an ingenious move of the incumbent that allowed this to happen, but rather a result of the established company “dropping the ball.”
As companies grow their customer base, and gain experience satisfying them, their customers grow accustomed to that business accomplishing a certain task for them. The company or product’s brand name may even correlate with the task the customer uses it for. Xerox, Kleenex, and Band-Aid are some extreme cases of brand-names being used as the generic name of the product itself. In fact, as long as customers are continually satisfied with their purchases, the act of going to that company’s brand to accomplish a specific task becomes habitual.
