CRM software fulfills the customer-side of the system. Customer relationship management systems (or CRM systems) focus on just that : customers. This software manages customer information and captures all relevant details for the company. This information is used all across the board, from sales reps to managers to accounting personnel. A quality CRM system should capture every interaction the company has with the customer. By properly managing customer information, companies can build their customer relationships in order to increase customer loyalty and, ultimately, revenue.
