Customer Relationship management is an approach to managing a company's interaction with current and potential future customers  that tries to analyze data about customers' history with a company and to improve business relationships with customers, specifically focusing on customer retention and ultimately driving sales growth.The primary goal of customer relationship management systems is to integrate and automate sales, marketing, and customer support. Therefore, these systems typically have a dashboard that gives an overall view of the three functions on a single page for each customer that a company may have. The dashboard may provide client information, past sales, previous marketing efforts, and more, summarizing all of the relationships between the customer and the firm.
