It's a good solution for folks who are going to be out most of a month (something that happens regularly with my students), but nobody seems to be interested in it otherwise. I could see someone considering it when they start, but the cost for a month is the same as the cost of 5 classes, so they lose money if they come in twice a week for 3 weeks. I've considered letting folks buy a 10-class or 20-class package, to get a price similar to the monthly cost. Right now it would be too difficult to keep track of. If I ever get that database program to a beta stage, that kind of tracking would be part of what I'd have available.
Sorry... there's far too many posts between yours and the last one, but anyway...
It's very easy to keep track of. Sell them a "punch card" (don't know what else to call it). If each class is $10, sell a 5 class card for $50 and a 10 class card for $100. Every time they come to class, punch a hole in the card. When no more classes remain, they buy a new card.
I used those dollar amounts and class numbers because they were easy. Charge whatever you want. Give a discount on larger dollar amounts like 12 classes for $100 if you'd like.
My former sensei's wife ran cardio kickboxing in the dojo at non-karate times. That system worked great for them. He didn't do that for karate, but I can't see it not working. And it's pretty hard to scam - have your own card, and hand sign it when sold. Unless you can't recognize your own signature, there's no way I know of to get away with phony cards (not that they had any issues).
