The best CRM platform will help your business navigate relationship-building (and maintenance) with both current and potential customers.
Top CRMs will be able to:
Maintain a client database
track customer details
collect feedback from customer-brand interactions
trace the sales cycle from lead to sale
assist with marketing campaign development
assist with social media management
act as a contact center
However, small businesses may not need all these capabilities to start, but as your business grows, you likely will. Therefore, a CRM solution should be scalable and able to adapt to your business needs over time.
