The main purpose of a customer relationship management (CRM) system is to manage and analyze customer interactions throughout the customer lifecycle. By consolidating customer data from various channels, CRM systems enable businesses to better understand customer needs, enhance relationships, and improve overall satisfaction. Key functionalities include sales tracking, lead management, and customer support, all of which aid in driving sales growth and customer retention strategies. Ultimately, CRMs facilitate informed decision-making and personalized marketing efforts, thereby fostering long-term customer loyalty.
