Why the back office looks the same across disciplines
A piano teacher, a tennis coach, a swim instructor and a yoga teacher run very different lessons. The back office around those lessons looks almost identical.
There is a person who comes back week after week. There is a note on what happened last time. There is a payment that needs to clear. There is a parent or a partner who wants to know how it is going. There is a month that needs a summary.
That is the work simple software for private instructors holds. Not the lesson itself. The shape around it.
