CRM is a type of software available for business to improve their relationship with their customers and to gain prospective customers. It integrates the four aspects of customer relations i.e. Sales, Feedback, Support and Marketing into one tool. It is not only helpful in organizing a large customer base but also helpful to gain new customers and keep the existing customers happy with the company. This is very important for small businesses as their customer base isn’t as diverse or voluminous as large corporations.
