MSP ticketing system
Not a new subject, and I know a common consensus is "this is not done well overall."
Ticketing systems seem to be a dime a dozen. I've been using AutoTask most recently. Spiceworks obviously can't handle client isolation, as it wasn't designed for that.
I haven't used ZenDesk, but saw they do have a MSP offering. Also haven't used osDesk but have heard good things and was told they do have client isolation.
If you are working at a MSP, what are you using and why? Just some of the high points.
osTicket. It's free and open source and easily customizable. We've been generally happy with it.
