An online booking system is software that makes your facility's free time slots available to guests in real time, handles payments, passes and cancellations, and keeps all of it in a single calendar. Rollout usually takes 1–2 weeks; the cost is either a monthly fee or a commission per booking. The biggest gain is not the admin work you save, it is capturing the demand that arrives outside opening hours and is lost today.
- A booking system solves three things: availability around the clock, a conflict-free calendar, and commitment tied to payment.
- There are two pricing models: a fixed monthly fee, or commission on completed bookings. At low utilisation, the commission model carries less risk.
- Platform-based systems (like BookThis) bring in new demand as well; your own booking page does not.
- The critical step in a rollout is not the software, it is the data: opening hours, resources, prices, cancellation policy.
- Measuring success: share of online bookings, utilisation by time band, no-show rate, average booking value.
If you run sports courts, a gym, an event space or a studio, sooner or later the question comes up: is it worth switching to an online booking system, and if so, which one? This guide walks through every point that matters — from the basic concepts through pricing and the feature list to a practical rollout schedule.
1. What is an online booking system?
An online booking system is software that makes your facility's free time slots available to guests in real time, takes the bookings, handles payment and cancellation, and keeps all of it in a single calendar. The key word is real time: it does not send you a message you have to answer, it locks in a slot instantly and for good.
That difference matters more than it sounds at first. A form or a chat is “online” too, but with both of them you are the bottleneck. With a real booking system, you are not.
A good booking system is not defined by how many features it has, but by how many decisions it takes off your plate every day.
2. What does it actually solve?
2.1. Availability outside opening hours
The intent to book usually forms in the evening, when a guest looks over the week ahead. If they cannot book with you right then, chances are they will book somewhere else. The biggest return of an online system is not the admin work you save, it is capturing the demand you lose today.
2.2. A conflict-free calendar
A single double booking produces two unhappy guests, and making it up to them costs money too. The system makes it physically impossible for two bookings to land on the same resource at the same time.
2.3. Commitment through payment
Guests turn up far more often for a slot they have paid for in advance or secured with a deposit. It is the single most effective way to cut no-shows — we have a separate article on it.
2.4. Data you can actually decide on
Utilisation by time band, average booking value, cancellation rate, share of returning guests. Without these, pricing and opening hours are guesswork.
3. System types: calendar, booking page, platform
| Type | What it gives you | What it does not give you | Who it is for |
|---|---|---|---|
| Shared calendar (e.g. a spreadsheet, Google Calendar) | Internal visibility | Guest-side booking, payment, double-booking protection | A very small venue with a single resource |
| Your own booking page | Your own brand, full control | New guests — you have to drive the traffic there yourself | A venue with a strong brand of its own |
| Booking platform (e.g. BookThis) | Booking, payment, passes and built-in demand | A fully custom brand identity | Anyone who wants new guests, not just a system |
The difference in a nutshell: your own booking page serves demand, a platform brings it too. If your growth today depends on how many people know you exist, that is the deciding factor.
4. What does it cost? The two pricing models
Two models have taken hold in the market:
- Fixed monthly fee. Predictable cost, but you pay it even in a month with barely any bookings. It can pay off at high, steady utilisation.
- Commission on completed bookings. No setup fee and no monthly fee; the provider earns when you do. BookThis uses this model: Basic 8%, Standard 12%, Professional 16%, and the commission covers the payment transaction cost as well.
Work out the break-even point. If a monthly-fee system costs HUF 30,000/month and the commission model takes 8%, the commission model is cheaper up to HUF 375,000 of online booking revenue per month. Above that the monthly fee wins — but only if it does the same job. You also have to count in the value of the new guests the platform brings.
5. Features worth insisting on
- A calendar per resource with double-booking protection (court, room, table, coach).
- Flexible time blocks and a mandatory buffer between two bookings.
- Integrated online payment, with a deposit or full-amount option.
- Pass and credit management with automatic deduction and expiry.
- A cancellation policy the guest can see before booking.
- Automatic reminders by push notification or email.
- Manual booking entry — guests who call in land in the same calendar.
- Permission management for the front desk, coaches and owners.
- Reports and export for accounting.
- Multiple locations under one account.
6. Live in two weeks — step by step
The software side is a matter of hours. The real work is gathering the data. A realistic schedule:
| Day | Task | Result |
|---|---|---|
| 1–2. | List your resources: every court, room, table and coach separately | Resource list |
| 3–4. | Opening hours, seasonality, public holidays, maintenance closures | Calendar skeleton |
| 5–6. | Prices and price bands, pass options, cancellation policy | Price list |
| 7. | Internal test: 10 trial bookings, including a conflict and a cancellation | Issue list |
| 8–9. | Train the team, set up permissions | A team that is ready |
| 10. | Go live, tell your regulars | First online booking |
| 11–14. | Fine-tuning based on real usage | Stable operation |
Do not switch off the phone right away. Run both channels in parallel for the first month. Regulars move over on their own once they see the app is faster — you do not have to push them.
7. How do you measure whether it paid off?
Four metrics are worth tracking, month by month:
- Share of online bookings within all bookings. This shows how far your guests have made the switch.
- Utilisation by time band. Peak hours will grow first, but the real success is off-peak hours starting to move.
- No-show rate, broken down by payment method.
- Average booking value. If it rises, you are selling add-on services and passes well.
Within three months every one of these moves far enough to make the decision well-founded.
8. Five common mistakes
- Incomplete data. If the opening hours or the price are wrong, the guest loses trust at their very first booking. The data matters more than the system.
- An over-complicated price structure. Two or three price bands is what a guest can keep track of in their head.
- Launching without a cancellation policy. No policy is not flexibility, it is an argument at the front desk.
- No word about the switch. Your regulars do not know they can book online now.
- Not measuring. If you do not know your starting numbers, you will not know later what changed.
In summary
An online booking system is not a software purchase, it is an operational decision. The biggest gain comes from the guests who do not book with you today simply because they cannot — in the evening, at the weekend, or because they hate making phone calls. Start the rollout with your data and measure the outcome, and three months will show you exactly what it was worth.
Frequently asked questions
What does a booking system cost?
Two models are common. With monthly-fee systems you pay a fixed amount no matter how many bookings you get. With the commission model — this is how BookThis works — there is no setup fee and no monthly fee, you only pay on completed bookings (8–16%). At low or fluctuating utilisation, the commission model is the less risky one.
How long does it take to go live?
The software side is a matter of hours. The real work is gathering the data: resources, opening hours, prices, cancellation policy. A realistic pace: data entry and internal testing in week one, going live for guests in week two.
Will I lose the personal connection with my guests?
No, it just shifts. The phone does not disappear, it simply stops being the only booking channel. The time you free up goes into the things that genuinely need a human being.
What happens to my existing phone bookings?
You enter manual bookings into the calendar yourself, so online and phone bookings sit in one place. The system filters out any conflicts.
