Trenoxa ‑ Class Booking

Sell class, workshop, and event seats — capacity that can't be oversold. We'll set it up for you.

Never sell the same seat twice. Trenoxa lets you sell class, workshop, and event seats through your normal Shopify checkout, with per-session capacity that can't be oversold even when two customers race for the last seat. Create a class once, add recurring or one-off sessions, and customers book at checkout with live seats-left shown. Refunds and cancellations release the seat automatically, and every session keeps a roster. Short on time? Email us and we'll set your classes up for you, free.
