Ever since the concept of holistic marketing has been developed the business enterprises across various industry fields have realized that achieving sales targets alone will not help them in surviving the competitive market scenario. The external environment surrounding the businesses today is dynamic and uncertain. Therefore, sustenance and stability of the business enterprises depends directly on the nature of relationship it has maintained with its clients. While the new customers are important for continuous growth of the business at the same time managing and retaining the old customers works as the backbone of the company. Studies show that acquiring new customers costs 6 to 7 times more to the companies. From the marketing and sales point of view the existing clients are also indirectly responsible for generating genuine sales leads through the verbal referrals. A positive recommendation from an existing client will have a lasting positive impression. This is a cost-effective way of indirect marketing for the companies. Thus an essential part of business is to help keep up and grow your customer base to harvest the profits for longer period.
