When I began shopping for a CRM, simplicity and stability were the most important factors for me. Too many CRMs have far too many bells and whistles, most of which go unused once the program is set up and running. SpinOffice is simple, yet robust, and I have had exactly ZERO hours of downtime since I began using the product. Customer support is second to none, and the company is always probing for ways to improve functionality while still maintaining the elegance and simplicity that I find so appealing.
