Customer profitability
Customer profitability (CP) is the profit the firm makes from serving a customer or customer group over a specified period of time, specifically the difference between the revenues earned from and the costs associated with the customer relationship in a specified period. According to Philip Kotler,"a profitable customer is a person, household or a company that overtime, yields a revenue stream that exceeds by an acceptable amount the company's cost stream of attracting, selling and servicing the customer."
