Template: pay-as-you-go classes

You can sell classes to people who are not members. Create a plan priced at zero that exists only to let someone book, then attach each class to it with its own price. A visitor signs up, joins the free plan without ever reaching a payment screen, and pays by card for each class they book — the same checkout your members use.

From there you can layer the usual variations: prepaid class packs where the first eight are included and the ninth is charged, a day pass priced by the number of days chosen, and a monthly plan for the regulars. Someone who books often can move to a monthly plan without losing their history.

Two things worth knowing before you set it up: the customer still creates an account, because that account holds their bookings, health declaration and receipts; and because a free plan never touches a card, there is no card on file to charge a late-cancellation fee against until their first paid booking.
