A booking system for personal trainers and fitness coaches — book classes and take payment upfront

Freelance personal trainers and fitness coaches don't have to trade times back and forth in chat. Zentr lets you build one booking link with your classes and per-session prices. Clients pick a slot you're actually free and pay the class fee in the same page — and overlaps are blocked automatically.

The problem

Why scheduling a session eats more time than the class

Most personal training and coaching work starts with scheduling. A client asks which days you're free, suggests a time, you suggest another, and it takes several rounds to land one slot — and often they reschedule or don't show, because nothing was holding the time.

Then come overlaps and lost income. Your schedule lives in several places — chat, calendar, notes — and you take two classes in the same window, or hold a slot for a client who never shows while someone else could have had it.

Common symptoms

  • Trading times back and forth for several rounds to book one class
  • Double-booking the same window because your schedule lives in several places
  • A client books and reschedules or never shows, with no fee holding the slot
  • Running both single sessions and multi-session packages, managed together until it gets confusing
How it works

How Zentr helps personal trainers and fitness coaches

One booking link

Clients pick a time from slots you're actually free

Build a booking page with your classes, per-session prices and the slots you're actually free. Clients pick a time that works and book themselves — no trading times back and forth — and the system locks a booked slot immediately.

Result
No more scheduling one class message by message
Sell packages

Take the class fee upfront, paid straight to you

Set clients to pay the class fee or a deposit when they book, through Omise or Stripe. The money goes directly to your account and Zentr takes no commission. A paid class is a client who genuinely intends to show — fewer no-shows.

Fees
Only Omise/Stripe's standard rates
Multiple classes

One-on-one, group, packages and online, kept separate

One-on-one sessions, multi-session packages, group classes, or online coaching — set each as its own service with its own price, duration and details. Clients choose the one they want before picking a time.

Supports
One-on-one, group and online, with details per class
AI chat

Answers questions and availability for you

The Plus plan includes an AI chatbot that answers questions about classes, prices and open slots, then sends clients to your booking page. Clients who message after hours still get an answer and can book right away.

Quota
2,000 answers per cycle, then shows your contact method
Before a class

One client, start to finish

It's 9pm and someone messages after seeing your post: "I'd like one-on-one training to lose weight. What days can we meet?" Instead of suggesting a time and waiting for a reply, you send a single booking link.

The client opens your one-on-one training package, sees the price, picks Wednesday morning while you're actually free, and pays the class fee right there. The system locks that slot immediately — anyone who opens the link later won't see it as available. In the morning you have a confirmed, paid class waiting.

FAQ

Questions personal trainers and fitness coaches ask

Can clients book a training session through one link?

Yes. You create one booking link with classes such as a one-on-one session or a multi-session package, each with a price and duration. Clients open the link, pick a slot you are actually free, and book in a single page. The system locks a booked slot immediately so no one else can double-book it.

Can I sell packages and take payment upfront?

You can collect a class fee or deposit at booking through Omise or Stripe. The money goes straight to your account and Zentr takes no commission — only the payment provider's standard fee applies. It cuts down on people who book a slot and don't show up.

Online, one-on-one and group classes — can I set them up separately?

You can set each one as its own service — one-on-one, group class or online — with its own price, duration and details, then state the location or how you meet in the service description. The Free plan allows 10 services; Solo and Plus add unlimited ones.

Clients message about availability after hours. Can it reply automatically?

The Plus plan includes the Zentr AI Chatbot with 2,000 answers per billing cycle. It answers questions about classes, prices and open slots and sends clients to your booking page. You can share the chatbot link on social media. When the quota runs out it stops answering and shows the contact method you set.

Got open slots? Let clients book them themselves

Create a booking page free on the Free plan, add your classes and the time slots you open, and share the link in your bio. Clients can pick a time and pay the class fee without trading messages back and forth.
