The ticket part I guess is pretty straightforward, so I'll try to explain the second:
I recently started to work with a small company: We manage the support for a few different enterprises. When we answer to issues that need us to go phisically to the place for the repairs, we charge per time. So we need a way to Report that visit to our client's enterprise manager/director/boss to justify the charge at the end of the month.
Right now we are doing it with a paper report we fill on the spot and make two copies, one is signed by the manager/director/boss and we keep it as proof of compilance with the service provided.
But I feel this way is slow and wastes paper, and I was wondering if we couldn't simply have a report software that would let us do it digitaly, and then maybe have the manager/boss sign in a tablet or phone. And by the end of each month send them all.
It doesn't need to be the same software performing both tasks. In price limit, I would prefer a free one (and open source too). In regards to OS, well it could be web based or need to run in Windows (as most of our clients run it).
