The AvaiBook Fast Check-in alternative focused on traveller registration
Fast Check-in is the traveller-registration module built into AvaiBook’s channel manager. Using published figures, we compare when an all-in-one platform suits you and when a specialised check-in tool that connects to your PMS suits you better.
In short: AvaiBook Fast Check-in versus BookCheckin
Fast Check-in is the traveller-registration module built into AvaiBook, a channel manager and vacation-rental management system; per its website (consulted July 2026), it files automatically with SES Hospedajes, the Mossos d’Esquadra, and the Ertzaintza, with pre-arrival online check-in, digital signature, and document scanning on its PRO plan. That regional coverage is a genuine advantage over BookCheckin, which today files only with the national SES. BookCheckin, in turn, is a specialised check-in platform that connects to your PMS: it publishes its price (from €3/property/month, with 3 months free), lets you sign up without a sales demo, does not store document images, and lets you cancel or correct an already-filed report from the dashboard.
AvaiBook Fast Check-in and BookCheckin: different approaches
AvaiBook is a vacation-rental management platform (channel manager and booking engine), and Fast Check-in is its own traveller-registration module, integrated into every booking — per its website, "not an external tool". BookCheckin is not a channel manager: it is a check-in and traveller-registration platform that connects to your PMS (Amenitiz, Cloudbeds, Hostaway) so every booking generates its link automatically.
Both let the guest complete online check-in before arrival, sign digitally, and generate the RD 933/2021 traveller report. The difference is not whether you are compliant — with either you are — but the model: AvaiBook gives you the all-in-one (channels, bookings, and registration), and BookCheckin gives you a specialised piece that fits on top of the tools you already use.
Model and scope: AvaiBook Fast Check-in vs BookCheckin (2026)
AvaiBook does not publish the price of Fast Check-in on the product page: per its website (consulted July 2026), the tool is included in several of its plans (Estándar, Avanzado, Premium, Líder, and Pro), and you request a demo to learn the terms. Document scanning, per its website, is available on the PRO plan.
BookCheckin publishes its three plans with the final price — Basic €3, Pro €5, and Business €7 per property per month — with self-serve sign-up, no property minimum, and the first 3 months free. AI document scanning is included from the first plan and images are not stored.

Why some accommodations choose BookCheckin
If you already have your channel manager or PMS and what you want is the best check-in and registration piece to fit on top, BookCheckin is built for exactly that.
- ✓Published pricing from €3/property/month, with no minimums and self-serve sign-up: you see the figure and start the same day, no mandatory demo.
- ✓AI scanning of DNI, NIE, and passport included from the first plan, without storing document images.
- ✓Native PMS integrations (Amenitiz, Cloudbeds, Hostaway) and sync with Booking.com and Airbnb.
- ✓Self check-in with Nuki, TTLock, and igloohome smart locks, with virtual keys conditional on completed registration.
- ✓Automatic SES Hospedajes filing with receipts and error handling built from real production cases.
- ✓Cancellation and correction of already-filed reports from the dashboard, without tickets or waiting.
- ✓Multi-property and multi-company structure with team roles, for managers operating properties owned by several landlords.
When AvaiBook is the better choice
An honest comparison has to say when the other tool wins, and with AvaiBook there are two clear scenarios.
First: if you want an all-in-one. AvaiBook is a full channel manager — it syncs channels, manages bookings, and brings traveller registration integrated into the same platform; if you prefer a single tool for channels, bookings, and check-in rather than a specialised piece plus your PMS, AvaiBook fits better.
Second, and decisive: if your accommodation is in Catalonia or the Basque Country. Per its website, Fast Check-in also files automatically with the Mossos d’Esquadra and the Ertzaintza. BookCheckin, today, files only with the national SES Hospedajes: in those two regions we digitise data collection and signature, but you submit the regional report yourself. If you need that filing automated, that is a strong reason to choose AvaiBook over us.
How to add BookCheckin on top of your AvaiBook operation
There is no data to import: configure your properties and SES Hospedajes credentials in BookCheckin, verify a real filing, and then decide which tool you use for registration. With the 3 months free you can test it without paying two subscriptions at once.
- 1
Keep your SES Hospedajes credentials at hand
The establishment code and landlord credentials are yours and work with any tool. Locate them first.
- 2
Create your BookCheckin account and add your accommodations
Sign-up is self-serve and the first 3 months are free, so you can test in parallel at no cost while continuing your current operation.
- 3
Connect your PMS
If you use Amenitiz, Cloudbeds, or Hostaway, enable the integration so bookings flow in on their own and each one generates its check-in link automatically.
- 4
Verify an accepted report with its receipt
Complete a trial check-in and confirm in the dashboard that SES Hospedajes accepts the report and the receipt is archived.
- 5
Compare with real bookings and decide
Test both flows over several arrivals. Bear in mind that if you operate in Catalonia or the Basque Country, automated regional filing is an AvaiBook feature, not a BookCheckin one.
