Trenoxa - Class Booking

Bookings that never double-book. Sell classes and workshops with recurring sessions and a seat limit on each one.

Install Trenoxa from the Shopify App Store, then open it from your Shopify admin under Apps.

Recurring sessions. Set a weekly schedule once and Trenoxa generates every session, each with its own capacity.
Seats that hold. A seat is claimed before checkout starts, so two customers can never buy the last spot.
Real Shopify checkout. Customers pay through your existing checkout; refunds and cancellations release the seat automatically.
