Personal trainer scheduling software that fills its own gaps.
Clients book themselves. Credits deduct, GST invoices follow, and the 5:50am cancellation turns back into a booked session.
From A$6 a month. No card required.

Every session type
Group classes, privates, drop-ins, reformer reservations. One calendar, every booking model you run.
Waitlist auto-promotion
The moment a seat opens, the next person is in and confirmed. Nobody has to be watching.
No double bookings
Capacity, overlap and buffer windows are enforced on the server, so two clients cannot claim the same slot.
Most software tells you the 6am is empty. It does not fill it.
The message lands in your inbox and REPley drafts the reply in your voice, with real times from your calendar attached. You send it. Your client taps a slot and rebooks before you have finished your coffee.
One message. One tap. No phone tag.
REPley drafts, you send. Nothing reaches a client without your approval.
Pick a session time
Times from your real availability.
None of these work
Rebooked for tomorrow, 6:00 am
The booking and the money are the same record.
Packs and memberships are built in. A booking deducts a credit, the GST invoice follows with your ABN on it, and payments land in your own Stripe account with no commission taken. Nothing to reconcile at the end of the month.
Questions trainers ask
What is personal trainer scheduling software?
Personal trainer scheduling software manages when your sessions happen and who is booked into them. You set your bookable hours once, clients book themselves into the gaps from a phone, and the software enforces the rules around it: buffer time between sessions, how far ahead someone can book, cancellation windows, and daily caps. BuildStability adds the money side to the same record, so a booking also deducts a session credit and produces a GST invoice.
Can clients book their own sessions?
Yes. You set your availability windows and clients book inside them from their own phone, at any hour. You choose whether a booking confirms instantly or waits for your approval, so trainers who want to keep control of the diary can have it. Regular weekly clients stay booked automatically through recurring sessions.
Is there personal trainer scheduling and billing software that does both?
BuildStability runs scheduling and billing off one record instead of two systems that have to be reconciled. Session packs and memberships are built in, a booking deducts a credit at the moment it is made, and the GST invoice follows with your ABN on it. Payments go through Stripe into your own account with no commission taken on client payments.
What happens when a client cancels at the last minute?
The cancellation is where most scheduling software stops and BuildStability keeps going. When a client messages to say they cannot make a session, REPley, the AI assistant built into BuildStability, drafts a reply in your voice and offers real times from your calendar as a card the client taps to rebook. You review and send the draft yourself, so nothing reaches a client without your approval. No-show tracking flags the clients who make a habit of it.
Is there a personal trainer scheduling app for phones?
Yes. BuildStability ships iOS and Android apps for both sides. Trainers manage the diary, approve bookings and reply to clients from their phone, and clients book, reschedule and check in from theirs. The web version does everything the apps do, so nobody is forced to install anything to get started.
Can it handle group classes and waitlists as well as one-to-one sessions?
Yes. Classes carry a capacity limit and a waitlist that promotes the next person automatically the moment a seat opens, so a cancelled spot refills without you watching for it. QR check-in handles attendance at the door, and studios running reformer or equipment-based classes can reserve specific spots.
Does it handle Australian GST and tax invoices?
Yes. BuildStability is built in Australia for Australian and New Zealand trainers. Once you are registered for GST, invoices show the GST amount and your ABN in the format the ATO expects, and payment records export as CSV for your BAS. New Zealand businesses get 15% GST invoices with a GST number. Most scheduling platforms are built for markets without GST and cannot produce a compliant tax invoice at all.
How much does personal trainer scheduling software cost?
BuildStability starts at A$6 per month on Essential for up to 6 clients, then Starter at 25 clients, Pro at 100 and Pro+ at 250. Scheduling, billing, classes and the AI assistant are included on every plan rather than reserved for a premium tier, and there is a free 14-day trial with no card required.
