Don’t limit yourself to what you currently assume a CRM system can do. If what your business really needs is a solution that integrates customer data, email marketing, travel planning, event bookings and managing your complete iTunes collection all in one place, write that down. You may not find everything in a single CRM solution – you may even find what you need and discover the vendor doesn’t call it a CRM solution at all – but knowing what you want is a great place to start from.
