Hotel booking engine: what small hotels need
GuestJourney editorial team, edited by Alon Shkuri
A hotel booking engine is the software that lets a guest see availability and book on your own site, without an OTA. A small hotel does not need to build one: all 20 small hotels we checked on 1 November 2026 used an outside engine, under ten different names. What matters is whether it works on a phone, connects to Google and keeps your calendars in step.
Three demo links, and a menu to write on
Anna is at the desk of Hotel Kadeloft with the contract of her booking engine. It runs out in three months. Last week Laura, who stayed in the spring, wrote that she had tried to book again on her phone, got stuck on the third screen and did it on Booking.com instead. That is €16.50 a night Anna did not need to spend.
Three suppliers have sent her a demo link, and on the big screen in the back office all three look fine. So she turns a breakfast menu over and writes down what she actually wants to know.
Hotel Kadeloft, Anna and Laura are made up, so the sums in our guides are about something.
Three systems, sometimes sold as one
A supplier can sell all three as one package, under different names, so ask what is included. The last column is our view.
| System | What it does | Do you need it? |
|---|---|---|
| Booking engine | Takes bookings on your own website | Yes, if you want direct bookings without email |
| Channel manager | Keeps prices and availability equal across OTAs and your site | Yes, once you sell through more than one channel |
| Property management system | Runs the hotel: rooms, guests, invoices | Depends on how you work now |
In the HOTREC study of 2024, 62% of European hotels used a channel manager, up from 39% in 2013, and bookings through a hotel's own engine grew from 7.4% to 12.3% of overnight stays. Size shows: among hotels with fewer than 20 rooms, 53% used a channel manager and 43% still managed their channels by hand.
The study says a channel manager lowers the risk of overbooking. Anyone who has had to walk a guest to the hotel down the road on a Saturday night knows what that is worth. If you are in that 43%, we would fix this first.
The names behind the Book buttons
On the 20 small hotels and 10 B&Bs we checked, these are the names behind the Book buttons. This is what we saw on these sites, not a ranking or a recommendation: we did not test any of them, and we sell none of them.
| Group | Names, with how often we saw them |
|---|---|
| 20 small hotels | Mews 5, Cubilis/Lighthouse 4, Hoteliers.com 2, RoomRaccoon 2, SiteMinder 2, Bookscapia 1, Guestline 1, HOP 1, Preno 1, Rumo 1 |
| 10 B&Bs | Cubilis/Lighthouse 3, Bedandbreakfast.nl 2, eviivo 1, MyTourist 1, SiteMinder 1, and 2 by phone or email only |
On 15 of the 20 hotels, the Book button pointed to an address of the supplier, such as app.mews.com or booking.roomraccoon.com. For these 20 we looked at homepages only and clicked nothing, so this says nothing about how well any engine works.
The test that counts is on a phone
A demo on a big screen shows you the best version of the product. Ask for a trial link with your own hotel in it, turn off the wifi, and book.
- 0:00The buttonWifi off, out on the quay. Is Book visible without scrolling, with no cookie banner on top?
- 0:20The datesTwo nights in May, with one thumb. Does she have to choose the dates twice?
- 0:50The priceIs this her homepage price? Can she see city tax and breakfast before the last screen?
- 1:20The extrasCan she add the dog at €15 a night, or only as a note in a text box?
- 1:50The formCount the fields. Number keys for the phone number? Does one mistake wipe the rest?
- 2:30PayingCan a guest pay with what is on the phone, or fetch a card first? She stops here unless there is a test mode.
- 3:00The emailWith a test mode: does the confirmation show the hotel's name, how to cancel and how to reach her?
- 3:30Booking.comIn her Extranet: has that room closed? She cancels the test and checks that it opens again.
Write down screens and minutes. We have no benchmark for either, so compare the candidates with each other, and with booking the same room on Booking.com on the same phone.
Six things a small hotel needs from one
- It works on a phone. The test above. If you cannot finish it with one thumb, do not expect a guest to.
- The guest stays with you. Your name and photos on the booking page, not the supplier's, and no other hotels offered.
- A price that matches. The price on your page and the one in the engine are the same, including city tax and breakfast. Google counts this too: free booking links are ranked partly on how accurate the prices it received have been.
- Your calendar stays right. If you also sell through Booking.com, a booking on one must close the room on the other. Otherwise you will double-book.
- It connects to Google. Ask whether it sends your rates to Google for free booking links. Google charges no fee and nothing per click, and says an owner on a reservation system may already be connected through the provider. We would ask this one first.
- You can leave. Who owns the guest data, and can you take it with you?
Google keeps a directory of connectivity partners, the companies that send a hotel's rates to it. On 2 November 2026 we found Cubilis, Hoteliers.com, RoomRaccoon, SiteMinder, Guestline, HOP and eviivo there. Other names we saw on hotel sites were not in it under those names, and that proves nothing: a supplier may connect some other way. So ask.
Monthly fee or percentage: do the sum
Ask whether you pay a monthly fee, a commission per booking, or both. We collected no price lists, so both prices below are made up. Put in the quotes you get.
| Step | Sum | Result |
|---|---|---|
| Flat fee of €150 a month | €150 x 12 | €1,800 a year |
| 3% on one night at €110 | 3% of €110 | €3.30 |
| Where the two cost the same | €1,800 ÷ 3% | €60,000 of bookings |
| That in room nights | €60,000 ÷ €110 | about 545 |
| Share of Kadeloft's 4,380 nights | 545 ÷ 4,380 | about 12% |
Below about 545 nights a year through your own engine, the percentage is cheaper. Above that, the flat fee is. Then add what a quote can leave out: a setup fee, each connection, and card payments.
Set that €3.30 next to Booking.com's €16.50 on the same night at 15%. The comparison only holds for a guest like Laura, who already knew Kadeloft. Jonas found the hotel on Booking.com, and no engine would have brought him. The commission calculator does the same sum with your own numbers.
Do you need one at all?
With one or two rooms, and no OTA, email and a telephone can be fine: see what a B&B website needs. From about the moment you sell through a second channel, or lose guests who want to book at 11 at night, an engine earns its fee. That is our judgment, not a measured line.
How it fits on your website
The simplest setup is a plain link: every Book button goes to the engine's page, ideally with your dates already filled in. A form embedded in your own page can look nicer, but it adds a script to that page, so run the phone test on that version too. Whichever you choose, the button has to be on the first screen.
Of the 20 hotel sites we opened on a phone, 16 had a readable Book button on the first screen, and on 2 of those a cookie banner lay over it.
What to ask, and what a good answer sounds like
Send these by email, so the answers are in writing. The right-hand column is our view, not a quote from a supplier.
| Ask | A good answer sounds like |
|---|---|
| Can I test this with my own hotel, on my own phone? | "Yes, here is a link. Try it before we talk again." |
| What do I pay in a year at 500 bookings? | A total in euros, with every fee in it. |
| What do card payments cost on top, and when does the money reach me? | A percentage and a number of days, in writing. |
| Do you send my rates to Google for free booking links? | "Yes, this is what we set up and this is what you do." Or a plain no. |
| Which OTAs and channel managers do you connect to, and what does each cost? | A list with prices, and how long a booking takes to close the room elsewhere. |
| Which languages does the booking page speak? | A list, not a promise. |
| What happens when it is down? | Who you call on a Saturday, and what the guest sees. On the day we measured, one B&B's site said its booking provider was down. |
| What is the notice period, and what can I take with me? | A period from the contract, and an export you can run yourself. |
