Customer relationship management, or CRM, is a software used to build and manage communication between a company and its customers or prospective customers. It's primarily used by sales, customer success and marketing teams to improve and streamline processes including lead tracking, customer segmentation information and task management.

CRMs are used to increase sales and improve retention by shortening the sales cycle, and monitoring and following up regularly with active customers. A good CRM tool will help attract, delight and engage in order to scale your B2B SaaS business.
