CRM stands for customer relationship management. It is a comprehensive strategy and process to acquire, retain, and partner with selective customers to create value for both the company and customer. CRM uses tools like software and technologies to automate and improve business processes related to managing customer relationships in areas like sales, marketing, customer service, and support. There are three main types of CRM technologies: operational CRM, which provides support for front office functions; analytical CRM, which analyzes captured customer data; and collaborative CRM, which facilitates interaction and communication between the customer and company channels.
