Hi. I have been using Square for probably 10 years now. But never as my main POS.
I would like to start using it as such, but I think the main limitation would be running tickets.
For example, someone brings in a computer for a repair, and as I work on it, I may need to add a repair price. No biggie. But say the client now wants to come in for a consulting session. Now I would like to add that session to their current balance / ticket, then check them out once all charges are complete.
I also have clients who I continuously add charges to their ticket for consulting phone calls, etc, then bill them out manually each month.
How would YOU do this? Thanks!
