Education & courses
Seats that sell themselves
Publish a course with dates, capacity and price; enrolment, reminders and the roster take care of themselves.

Cohorts and one-offs
Weekly series or a single masterclass — both book against real capacity with a clear price.
Payment up front
Deposits or full prepayment keep seats for people who show up.
The roster, current
Who is coming, who paid, who cancelled — one list, exportable, always current.
This is the product, live
A teaching week planned in the calendar view.
