A CRM provides a centralized data repository to businesses where they can store and update customer contact information, interaction history, purchase records, and customer preferences. CRMs can also be integrated with various data sources to capture leads and their information automatically.
Most CRMs also let you create custom data fields to categorize and segment data on various grounds such as by customer, company, deal, or project. You can also give role-based access to data and ensure that no unauthorized users can access your data.
