Group classes: the highest-margin hour on your calendar
A one-on-one hour sells your time once. A class sells the same hour eight times. For yoga, pilates, group PT and workshops, the maths is transformative — if the admin doesn't eat the margin.
The unit economics
Eight spots at £12 is £96 for an hour that would earn £40–£60 one-on-one. Even at 60% fill you're ahead — and fill rate is a marketing problem you can work on, not a ceiling.
What the booking system must do
- Capacity per session, enforced at booking time — never oversold
- Spot-by-spot joining of an existing session
- Class passes (5/10/20) with automatic deduction
- A waitlist that emails everyone waiting the moment a spot frees up
Filling the back rows
Off-peak classes fill with coupons and passes: a '10 mornings' pass at a discount converts your 6pm regulars into 8am regulars. Track fill rate per class in your reports and cut or move what stays under 50%.
Slotora handles capacity classes, passes and the waitlist out of the box — free.
