Trenoxa ‑ Class Booking.

Sell class and workshop seats through your store's checkout, with capacity that can't be oversold.

Trenoxa is built for merchants selling scheduled group sessions — classes, workshops, courses, and timed admissions. Create a class once, then add recurring or one-off sessions, each with its own capacity and start time, timezone-aware. Customers pick a session and book through your store's normal checkout. A seat is claimed the moment checkout starts, so two people can't buy the last one at once, and refunds or cancellations release the seat automatically. Every session has a live roster.

• Sell seats for recurring or one-off class and workshop sessions
• Capacity limits that prevent overselling, even on simultaneous orders
• Refunds and cancellations release seats automatically for resale
• A live roster for every session showing who booked and seats taken
• Timezone-aware scheduling that stays correct across daylight saving
