I've been looking at PCRT for a few months now however I currently use ZenDesk and Freshbooks for tickets and invoicing. Currently I'm not looking to replace Freshbooks but I'm not completely attached to ZenDesk. I'm going to try the PCRT demo now with this new integration however I'm not so sure I'm ready to host it, or change customers over from Freshbooks (which I'm not sure there could be anything better).
Those of you that use it, could you help sell it to me? What do you like, what doesn't you like? I'm all for a better ticketing and tracking system however invoicing will take some arm twisting to make me switch; how far can you twist it for me?
