I've tested what seems to be every CRM out there. (At least 20 !) When I really prioritized what's important to get from a CRM, OnePage was my final choice.
Its easy to configure to the way in which you do business. It has a very user-friendly, uncomplicated interface. (Otherwise, who would want to use it?!) It has a totally useful mobile interface, and most importantly, lets you focus on moving your prospects through to closure. (And then lets you stay in touch!) I would highly recommend this to anyone who needs to get their lives and/or businesses in order! Oh... and I am recommending this to my own clients as well!
