Why "Salonized versus Treatwell" is the wrong question
Anyone searching "Salonized vs Treatwell" expects a winner: which of the two is better, cheaper, smarter? But that framing is wrong, and it gives you a distorted picture. Salonized and Treatwell are not two versions of the same product you pick between. They are two different kinds of thing that each solve a different problem, and that in practice are often used side by side.
Salonized is salon software: a system to run your salon, with a calendar, client management, and a booking page, for a fixed monthly price. What that monthly price actually is sits in the guide on Salonized pricing. Treatwell is a booking marketplace: a platform where clients find and book salons, that brings new clients to you for commission. One is a tool, the other an acquisition channel. Comparing them on "which wins" is like asking whether a calendar is better than an advertisement: they are different things. This is the Dutch salon market, where both operate.
There is a second reason the question is off, and it rarely appears in a comparison: since October 2024 they are not even two companies. Treatwell bought Salonized. Further down you can read what that means for your choice.
In this guide I explain what each of the two does exactly, how their cost models differ, who owns them today, and where a third model (pay-per-appointment) fits into this picture. No artificial head-to-head, but an honest view of two products that are often deployed together.
What does Salonized do?
Salonized is salon software with a fixed subscription model. You pay a fixed monthly price ex VAT, from 21 EUR for the Appointments entry plan to 39 EUR for Basic and 59 EUR for Pro, and get in return the tool to run your salon: an online calendar, a booking page where clients schedule their own appointments, client management, and automated reminders.

The key point: Salonized earns its money from the software, not from your clients. Whether you run 30 or 300 appointments in a month, the subscription costs the same. The system does not care whether a client is new or has been coming to you for ten years; it is a tool to manage all your appointments and clients, regardless of their origin.
That makes Salonized a typical software product: predictable fixed costs for daily operations. It does not bring in new clients on its own; it helps you serve the clients you have organized. Anyone who wants to acquire new clients does that through another channel, such as their own marketing or a marketplace.
What does Treatwell do?
Treatwell is a booking marketplace. Clients search the platform for a salon nearby, compare offerings and reviews, and book directly. For the salon, Treatwell is an acquisition channel: it brings in new clients you might not otherwise have reached, people who were actively looking for a salon and found you through the platform.
Against that stands a commission model. Treatwell charges 35% commission on new bookings that come in through the platform, plus 2% transaction fees on online payments through the platform. The 35% applies only to those new, via-Treatwell-acquired bookings, not to your own repeat clients who return directly. How that commission compares to other cost models is set out in the comparison between CelerBook and Treatwell.

The key point: Treatwell earns its money from the clients it brings in, not from a fixed software fee. It is not a system to run your salon; it is a place to be found that generates new bookings. That is why a salon can perfectly use Treatwell for acquisition and at the same time run a completely different system for the daily calendar and administration.
Not partners but one company: Treatwell bought Salonized in 2024
Here sits the core of the whole story, and the point almost every comparison misses. Salonized and Treatwell are no longer two companies. Treatwell acquired Salonized outright, the deal closed on 9 October 2024 and was announced the following day. Treatwell had held a stake since July 2021 and is now the sole owner; the product, the team and the expertise were folded into the Treatwell Group. In the announcement, Treatwell Group CEO Tobias Hinteregger says the group is delighted with the acquisition and welcomes the product and the team. Danny Hiemstra, who founded Salonized in Amsterdam in 2013, speaks in the same piece about the product he built.
One level up, the chain continues. Treatwell itself passed into full ownership of the Japanese listed company Recruit Holdings in 2015, which bought the shares in Treatwell Holdings B.V. through its UK subsidiary Hotspring Ventures, the company behind Wahanda that took the Treatwell name in early 2016. So the Dutch market leader in salon software sits under a Japanese holding company.

That changes the question you are asking. "Salonized or Treatwell" is not a choice between two suppliers who keep each other sharp, it is a choice about which product from the same owner you buy. The integration between the two is still there: bookings that come in through Treatwell land automatically in the Salonized calendar. It is just in-house traffic now, not a partnership between two parties each guarding their own interest.
Where you feel that is in the things you cannot negotiate. The subscription price for your software and the commission on your new clients are set by one party. Your client list, your calendar and your acquisition channel sit with one supplier instead of two. That is not a reason to walk away, but it is worth knowing before you sign up for both.
Practice confirms that. Many salons use both at once: Salonized to run the salon (calendar, clients, reminders) and Treatwell to acquire new clients. That is a logical combination, because they solve different problems. The software handles your daily organization; the marketplace fills your calendar with new faces. One without the other leaves a gap: only software and no acquisition, or only acquisition and no orderly system to serve the clients afterward.
That is why "which should I choose?" is often the wrong question. The better question is: "do I need new clients, a better system, or both?". If you have enough clients but want your organization in order, it is about software. If you have a fine system but too few clients, it is about acquisition. If you need both, you use both kinds of solution side by side, each with its own cost model.
In practice that combination works like this: a client finds you through the marketplace and books there, the booking lands in your salon software through the integration, and your reminders, client records, and calendar then run through your software. The marketplace has done its work once the client has booked; the software takes over after that. If that same client returns directly next time, that booking runs entirely through your software, without commission. That is why the two complement each other: the marketplace is the front door for new clients, the software is the system that manages your relationship with that client afterward.
The three cost models: fixed, commission, and pay-per-appointment
Now that the two different kinds of solution are clear, a third model fits the picture. For the software side (running your salon) there is, alongside the fixed subscription, also pay-per-appointment. That gives three cost models you can put side by side.
| Model | Example | Cost structure | When it makes sense |
|---|---|---|---|
| Fixed subscription | Salonized (21 to 59 EUR/month) | Fixed monthly price, regardless of volume | Predictable, high volume |
| Marketplace commission | Treatwell (35% new bookings + 2% transaction) | Pays per new client through the platform | Client acquisition |
| Pay-per-appointment | Usage model (around 0.25 EUR/appointment, with monthly cap) | Scales with appointments, capped | Low-to-medium volume, no contract |

Note that the three rows do not all measure the same thing. The fixed subscription and pay-per-appointment are both software models: they are about the price to run your salon. The marketplace commission stands apart; it is about the price of client acquisition. So you can perfectly combine a commission model for acquisition with a fixed or a variable software model for the daily organization.
The difference between the two software models is predictability versus moving with your volume. A fixed subscription costs the same every month and is favorable at high, stable volume. Pay-per-appointment charges per appointment and is more favorable at variable or low volume, with a monthly cap so the costs do not rise without limit even when busy. Neither is universally better; it depends on how many appointments you run and how stable that is.
Where pay-per-appointment fits as a third model
Both models above start from a monthly amount. A third one starts from your calendar: CelerBook charges 0.25 EUR ex VAT per completed appointment, the first 5 each month are free, and the bill stops at 30 EUR ex VAT a month plus 5 EUR per extra staff member. There is no contract, so a month without appointments is a month without an invoice.
That suits a salon whose volume moves: a first year that still has to fill up, a seasonal business, a solo operator working four days. It suits you badly if gift cards, a loyalty system or marketplace reach are what you were paying for. CelerBook offers none of the three. In that case the choice is not about the cost model at all, it is about which features you actually need.
How this differs by niche: nail salon versus massage practice
The three models do not hit a nail salon and a massage practice the same way, because each cost structure depends on a different trait of the business.
With the fixed subscription, the number of appointments per month does not matter. A nail salon with 220 short appointments in a month pays the same fixed 21 EUR as a massage practice with 15 long appointments. Per appointment that is almost negligible for the nail salon and steep for the massage practice: at 15 appointments, pay-per-appointment would cost only 2.50 EUR ex VAT, against 21 EUR fixed.
With the marketplace commission, it is the amount per treatment that matters, not the volume. At 10 new bookings through Treatwell, a nail salon with 25 EUR treatments pays around 87.50 EUR commission, while a massage practice with 90 EUR treatments pays 315 EUR for that same number of new clients.
The two cost models are sensitive on different axes: the fixed subscription on appointment volume, the commission on treatment amount. A nail salon with many short, cheap appointments and a massage practice with few long, expensive ones end up in a different place on the sum with each model.
Pay-per-appointment is the software model that combines the predictability of a subscription with the flexibility of a usage model. You pay per booked appointment, with the first few appointments per month free and a monthly cap. For a specific salon profile that is the logical choice.
It fits best with solo operations and small salons with variable or low occupancy, and with owners who do not want a fixed contract. In a quiet month you pay little because you ran few appointments; in a busy month it rises to the cap and you know it stops there. That is a different risk profile than a fixed subscription, where you pay the same every month, regardless of how busy you are.
Important to keep clear: pay-per-appointment is a software model, not a marketplace. It does not bring in new clients itself; it is a tool to manage your calendar and clients, just like a fixed subscription. Anyone who needs both acquisition and software still combines: a marketplace such as Treatwell for new clients, and a software model (fixed or pay-per-appointment) for the daily organization. The three models do not exclude each other; together they cover the two different needs.
How to put this in motion starting next week
Before you choose between Salonized and Treatwell, get clear on which problem you are solving: acquisition, software, or both.
Week 1: write down what you actually need. Are you missing clients, or missing an orderly system? That determines whether you look at acquisition (marketplace), software, or both.
Week 2: if acquisition is the problem, judge a marketplace on what it brings you: how many new clients does it bring in, and do those return afterward without commission? Count the commission as an acquisition cost per new client.
Week 3: if software is the problem, compare a fixed subscription with a pay-per-appointment model based on your volume. At variable or low volume per-appointment is often more favorable; at high, stable volume a fixed amount is predictable.
Week 4: combine where needed. The marketplace and your software system stand apart from each other and can be chosen separately.
