Customer Relationship Management (CRM) is the 21st century tech
support that helps marketers remain close to their customers to
understand and serve their needs at the earliest with the best
available resources.

While taking care of existing clientele, a CRM has all the data-driven
means to develop and bring in new customers from the stage of
developing leads to finally on-board and preserving clientele.

CRMs are a decision support service which collects, collates and
conjures customer-related data to provide the best insights into what
existing customers think and expect besides providing marketers a
clear picture on what it entails to develop and retain newer clients.
