Step-by-step explanation:
CRM refers to how a company manages its relationship and interactions with current and potential customers. The customers' information should be used to improve the relationship between the company and its customers by a process known as one-to-one marketing. One-to-one marketing should allow the company to customize their relationship with its customers and offer them specific products or services that fit their individual needs or habits. If carried out effectively, CRM should increase customer retention and ultimately increase total sales.
