A CRM or Customer relationship manager refers to procedures and rules that a company has put in place to guide its employees on how to deal with clients and their data. It is also the technology businesses utilize to track client information, manage customer interaction procedures, and get the most out of these activities.

 A CRM system is a central hub where multiple company units, including those in charge of sales, marketing, and customer care, may store, organize, and access all client data. For example, a CRM can facilitate quick access to a customer's purchase history and support history for customer service teams. Alternatively, it can be applied to more general circumstances, such as examining customer trends and patterns to get more precise estimates.
