Many CRM software vendors offer subscription-based pricing. However, some may charge a flat monthly fee for a set number of users (user per month); they may require you to pay extra for additional services, limited features and users.   Always remember that additional costs for possible additional onboarding, more advanced customisation, project management tools, and ongoing development may or may not be required now or later.   Most vendors provide various packages to suit functionality, features, users, customer records, mass email marketing list sizes and capabilities.   Most offer a 30-day free trial, and some will provide a free plan for 14 days or more to get started.
