The most helpful feature of Solve360 is the integration between all of the company areas (i.e. billing, accounting, operations and such).

I can easily forward an email to our crm email address and it will attach the record to the employee's file.

Solve360 is a great service all around. Their client Management service focuses heavily on contacts and companies, with all other features built in. Solve360 has really hit the nail on the head developing a system that is what small and large businesses alike really neat.
