Tracking 10 people's payments, doing the accounting of perhaps 80 payments a month (rather than 10) and the few minutes before each class to actually handle the payments. That time adds up. And it either takes time from teaching (bad for students) or takes time from something else in life (so it should be compensated).
No need to track anything . Accounting?
Just take cash and put what remains after hiring the room in your pocket. If not enough to cover hiring the room then stop.
