I've known the T360 guys since from when they first launch Field Agent in the UK many many moons ago and trust me, getting paid from them would never be an issue!
They've actually been pretty savvy if you think about. They obviously looked after Field Agent for a number of years and maybe saw the license they leased for that was coming to expire at a certain date and so made their OWN app (Task360) and spent time migrating the clients over to that. I think towards the end of them owning the Field Agent licence a lot of the main jobs has moved over to t360.
Now they've got full control, the majority of the same clients probably and don't have to pay for a license since they made T360 all by themselves.
