Pay-per-booking versus subscription: which fits?

Two ways to pay for salon software

Salon software is broadly billed in two ways, and the difference decides whether you throw money away in a quiet month or not. Most providers work with a fixed subscription: a fixed price per month, for a solo package usually between 21 and 49 EUR excluding VAT, that you pay whether you had 30 or 130 appointments. A smaller part of the market works with pay-per-booking: you pay per processed appointment, and in a quiet month the bill scales down with you.

Which model is cheaper depends on one number: your average appointments per month, and how strongly that fluctuates. For a busy salon with a stable high volume, a subscription can work fine. For a solo hairdresser, a startup, or a seasonal business, a fixed amount that keeps running every month is rarely the leanest choice.

In this guide I lay both models side by side, work through a concrete example, and show where the crossover sits. No sales talk: just the arithmetic, so you make the cheapest choice for your own situation.

Before you read on, it helps to know that "cheaper" is not the only criterion. Predictability has value: some salon owners would rather have a fixed amount they can budget immediately than a bill that varies per month. Others care more about a low bill in a quiet month. Both preferences are legitimate. What this guide does is put the real figures side by side so you make an informed choice rather than a choice on gut feeling.

How a fixed subscription works

A subscription is predictable and simple: you pay the same amount every month, regardless of usage. In the Dutch market the entry rate for a solo package sits roughly between 16 and 35 EUR per month. Da Vinci, for example, starts at 27.95 EUR, and Salonized works with plans: Appointments 21 EUR, Basic 39 EUR and Pro 59 EUR, all ex VAT (source: the Salonized help centre, updated 25 June 2026). What sits inside those plans and what is billed on top is in the guide on Salonized pricing.

The advantage is predictability. You know at the start of the year exactly what your software costs, and at high volume the price per appointment can fall low. A salon with 200 appointments per month effectively pays just over 10 cents per appointment on a 21 EUR entry plan.

The downside is that the price does not move with your revenue. In a dead-quiet January you pay that same amount for software you barely used. If you close for two weeks before a holiday, the subscription keeps running. And many subscriptions charge extra per staff member or for online booking, so the entry rate is rarely the final amount. Always read what is in the base package and what carries a surcharge.

How pay-per-booking works

With pay-per-booking you do not pay for a calendar month but for what you process. At CelerBook it works like this: the first 5 appointments per month are free, after that you pay 0.25 EUR ex VAT per completed appointment, with a monthly cap of 30 EUR for a solo business. No subscription, no fixed term.

The mechanism has three traits that set it apart from a subscription. First, it scales: a quiet month costs little, a busy month more, up to the cap. Second, there is a ceiling, so a peak month never runs away. Third, in a month with no appointments you pay nothing, which a subscription never offers.

The monthly cap is the part people often miss. Without a cap, pay-per-booking could work out more expensive than a subscription in a busy month. The 30 EUR cap for a solo business prevents that: however busy you get, you never pay more than 30 EUR. That makes the model combine the best of both worlds: low in a quiet month, capped in a busy one.

The worked example: a solo hairdresser with 80 appointments

Take a concrete case. A solo hairdresser processes 80 appointments in an average month. How does each model work out?

With pay-per-booking the first 5 appointments are free. That leaves 75 billable appointments. 75 times 0.25 EUR is 18.75 EUR ex VAT. That sits below the 30 EUR cap, so this hairdresser pays 18.75 EUR ex VAT for the month.

On a fixed subscription the same hairdresser pays the monthly rate regardless of the number of appointments: 21 EUR at Salonized Appointments, 27.95 EUR at Da Vinci, 49 EUR at Salonhub.

So the gap depends on who you compare against. Against Salonized Appointments it is 2.25 EUR per month, against Da Vinci 9.20 EUR and against Salonhub 30.25 EUR. Over a year that is 27, 110 or 363 EUR. And that is before counting the quiet months, in which pay-per-booking drops much further below the subscription.

A nail salon with the same solo setup shows a very different pattern. Shorter treatments of 30 to 45 minutes mean far more appointments per day: count 10 appointments a day, 6 days a week, which is roughly 260 appointments a month. On pay-per-booking that is well above the 125-appointment crossover, so this nail salon pays the 30 EUR cap. Against Salonized Appointments at 21 EUR that is 9 EUR more, against Da Vinci at 27.95 EUR 2.05 EUR more, and against Salonhub at 49 EUR still 19 EUR less. At that kind of high, steady volume a subscription becomes worth considering for a nail salon, while that same nail salon in a quiet build-up month with 40 appointments still pays only 8.75 EUR.

All amounts exclude VAT. The subscription rates are the entry plans, taken from the providers themselves on 10 September 2026: help.salonized.com, dvi.nl (on 8 September) and salonhub.nl/prijzen.html.

Calculation: 5 appointments free, then 0.25 EUR ex VAT per completed appointment, cap 30 EUR/month (solo). The subscription rates are the providers' own entry plans, fetched on 10 September 2026 (Da Vinci on 8 September).

The table shows that a solo hairdresser comes out cheaper or equal with pay-per-booking at almost every realistic volume. The figures in the "pay-per-booking" column are a neutral calculation based on the rate of 0.25 EUR per completed appointment, not a recommendation: it only shows how the model compares to the entry plans on the market.

Where is the crossover?

The crossover is the number of appointments at which pay-per-booking hits the monthly cap. For a solo business: 5 free appointments plus 30 EUR divided by 0.25 EUR per completed appointment, which is 5 plus 120, so 125 appointments per month. At 125 appointments you reach the 30 EUR cap.

But that cap is not the only tipping point, and here we should be more honest than most comparisons are. Each subscription has its own crossover, and where it sits depends on that provider's rate.

Against Salonized Appointments at 21 EUR, the crossover lands at 89 appointments a month: 21 divided by 0.25 is 84 billable appointments, plus the 5 free ones. Below 89 appointments pay-per-booking costs you less; above it Salonized does, by at most 9 EUR a month once you hit the cap.

Against Da Vinci at 27.95 EUR the point sits at 117 appointments. And against Salonhub at 49 EUR it sits nowhere: the 30 EUR cap stays below that however busy you get.

So the honest summary is not that pay-per-booking always wins. It wins in every quiet month, against every provider, and by a wide margin: at 25 appointments you pay 5 EUR against 21 to 49 EUR. Above ninety appointments a month, consistently, a 21 EUR entry plan can save you a few euro. Run it with your own number, because that is the only one that counts.

What changes with multiple staff?

The calculation above applies to a solo business. In a multi-staff model the cap shifts with you. At CelerBook the cap is 30 EUR for the solo owner plus 5 EUR per extra active staff member.

A salon with two staff then has a cap of 30 plus 5, which is 35 EUR per month. The crossover shifts with it: 5 free appointments plus 35 divided by 0.25, which is 5 plus 140, so 145 appointments per month before the cap binds. A salon with three staff gets a cap of 40 EUR and a crossover around 165 appointments.

A spa tends to hit this fastest, because spas often run several treatment rooms at once. A spa with four staff has a cap of 30 plus 15 (three additional staff members times 5 EUR), which is 45 EUR per month. The crossover shifts with it: 5 free appointments plus 45 divided by 0.25, which is 5 plus 180, so 185 appointments per month before the cap binds. For a spa with a broad treatment menu and several rooms, that 45 EUR cap is usually still lower than a subscription for the same number of staff.

Important when comparing: a fixed subscription almost always also charges per staff member. So compare like with like, on the same number of chairs. A 21 EUR subscription for one staff member is not a fair comparison with a pay-per-booking cap of 35 EUR for two staff. Put both models on your actual team size and your actual volume, and you see the real cost.

Which model fits which salon profile?

The arithmetic is the same for everyone, but the answer differs per type of business. A few profiles to recognize your own situation in.

The solo hairdresser or startup. Varying volume, often still below 100 appointments per month, and sensitive to quiet periods. For this profile pay-per-booking almost always wins: you pay little in build-up months and the bill only grows as you get busier. A fixed subscription feels to a startup like a fixed cost you pay before you have the revenue to carry it.

The seasonal business. Think of a salon with a busy summer and a quiet winter, or the reverse. Here the difference is largest. A subscription charges as much in the quiet months as in the busy ones, while pay-per-booking drops back to a few euros in a quiet winter. Counted over a full year, that difference adds up considerably.

The steadily busy salon. Month after month well above a hundred appointments, little fluctuation. For this profile the difference is small and a subscription can even come out slightly cheaper: pay-per-booking sits at the 30 EUR cap, Salonized Appointments at 21 EUR and Da Vinci at 27.95 EUR. A few euro a month. Here you choose on criteria other than price: which software has the features you need, and which provider demands no contract.

The salon still in doubt. Anyone still trying the software out or mid-switch is served by the model with no commitment. Pay-per-booking lets you stop at no cost if it disappoints, while an annual subscription locks you in before you know whether the software works for your way of working.

How to apply this next week

No rushed switch. A short calculation you do in half an hour that gives you the answer for your own situation.

Step 1: take your calendar from the past twelve months and count the appointments per month. Note the average, the quietest month, and the busiest month. These are the three numbers that decide your choice.

Step 2: work out what you would have paid per model. For pay-per-booking: number of appointments minus 5, times 0.25, with a cap of 30 EUR (solo) or 30 plus 5 per additional active staff member. For a subscription: the monthly rate times twelve, plus any surcharges per staff member and for online booking.

Step 3: compare the yearly total, not just the busiest month. The quiet months are often where pay-per-booking makes the difference, and those are easy to forget if you only look at a peak month.

CelerBook runs fully pay-per-booking: the first 5 appointments per month free, after that 0.25 EUR ex VAT per completed appointment, with a cap of 30 EUR per month maximum for a solo business (plus 5 EUR per additional active staff member).
