Fill your sessions.Get paid on time.Coach.
One widget on your site. Members book group sessions and PT slots, pay online, done. You stay on the floor, not behind the desk.
No credit card. No sales call. No BS.

Sounds familiar?
Front-desk reality, currently:
- Session sign-ups on a whiteboard, in DMs, and in somebody's head
- Chasing payments after the session instead of collecting before
- Two people on the same line of the sign-up sheet, one squat rack
- Paying enterprise prices for gym software you use 10% of
Your gym doesn't need more software. It needs less admin.
Made for gyms
How gyms run on bigZ
Group sessions, PT slots and course blocks - handled, paid, and full.
Capacity that enforces itself
Set max participants per session. Booking stops when it's full - no overcrowded classes, no arguments at the door.
Recurring session schedules
Your weekly timetable, set up once. Sessions generate automatically, and one-off changes don't break the series.
Paid before they show up
Members pay online when they book - cards, PayPal, iDEAL. No more collecting cash between sets.
Early-bird & last-minute pricing
Dynamic pricing rules fill quiet slots: cheaper early sign-ups, last-minute deals, capacity-based price steps - automatic.
Your coaches, their sessions
Invite your team with owner, admin and staff roles. Everyone sees what they need, nobody breaks the schedule.
Numbers at a glance
Revenue, bookings, your best-performing sessions - one dashboard instead of a spreadsheet ritual.
Gym questions
Nice things people said
I asked nicely.
“Switched from a €300/month system. This one actually works and saves us tons of money.”
“Set it up between lessons. Got my first booking the same afternoon.”
“I can check bookings from my phone. That's it. That's all I need.”
More reps, less admin.
Free to try. No credit card, no sales calls, no contract. If it's not for you, no hard feelings.
Setup takes about 15 minutes. One less excuse.
