Best Guest Registration Apps for Spain (2026)

Filing guest reports by hand is one of the worst ways a property manager can spend time: repetitive, against the clock, with a fine attached when something slips. Whether to automate it is not really the question, anyone who has handled six same-day arrivals over a long weekend already knows the answer.

The deadline and the channel are set by Article 6 of RD 933/2021:

“This communication shall be made immediately, and in any case within a period not exceeding 24 hours […] b) At the start of the contracted services. […] The communications provided for in this article shall be made by electronic means. Obliged parties carrying out lodging activities on a non-professional basis are exempt and may make them by non-electronic means, under the procedure to be determined.”

In plain terms: 24 hours from the guest’s arrival, filed electronically if your activity is professional. And the penalties are set by law: failing to file at all is a serious offence, €601 to €30,000; filing late or with errors in the data is a minor one, €100 to €600²³.

So the problem is not deciding whether to automate. It is choosing what with. Every option surfacing in a search presents itself as the complete answer, but they play in three different leagues: compliance specialists, property management systems with a registration module, and suites built around the entire guest journey.

RegistroViajero, first on the list, is ours. On price, the list sorts by league before it sorts by brand. Pure compliance starts at €5 + VAT per property per month with no minimum. What is advertised below that figure usually carries conditions⁴:

• Chekin: €3.95 per property per month, but only on annual billing. Month to month it is €4.95, and from three properties.
• Check-in Scan: from €6.95 a month plus VAT, with a one-year commitment and a ten-unit minimum on the monthly plan. The plan-by-plan breakdown of the check-in apps on the market is in the online check-in apps comparison.

Quick comparison: focus and filing destinations

All five file the report in your name, using your credentials. That is not a shortcut; it is the route the platform itself contemplates:

“The communication of the data may be made through a third party provided that the third party is authorised by the obliged party by any of the forms admitted in law to act on behalf of another person.”

What cannot be delegated is responsibility: the accuracy of the data in the report stays with the establishment⁵. Which is why what a tool validates before filing matters as much as what it files.

Six criteria for choosing a guest registration app

Beyond price, six things separate an app that removes work from one that just moves it around:

• Automatic submission and pre-validation. It should file the report to SES.HOSPEDAJES on its own and flag errors before sending, not when the fine arrives.
• Bookings in via iCal. If you key in every reservation by hand, you haven’t automated anything. Here’s how iCal sync works with Booking and Airbnb.
• Check-in languages. The guest fills in the form; if they can’t read it, you end up filling it in for them.
• Coverage for your region. The obligation is national: RD 933/2021 applies across the whole country, whatever the type of activity or the owner⁶. What changes by region is the counter. SES.HOSPEDAJES covers almost all of Spain, Galicia included, and only Catalonia and the Basque Country have their own channel. Galicia does add a quarterly occupancy return to TURESPAZO, a separate obligation that not every tool automates.
• Pricing with no fine print. Watch for minimums by property type and for paying for modules you’ll never touch.
• Support when something breaks. The deadline is 24 hours; if you get stuck on a Friday afternoon, it matters who answers, in what language, and how fast.

RegistroViajero

It does one thing: RD 933/2021 compliance end to end. The guest receives a check-in link in 9 languages, enters and signs their data, the system validates it against the Ministry’s rules and submits the report to SES.HOSPEDAJES automatically. Bookings flow in on their own via iCal from Booking, Airbnb, VRBO and other calendars.

The price is €5 + VAT per active property per month, no minimum, with a 15-day trial and no card. And when something goes wrong, support is us: direct answers from the people who know the product, not a ticket queue.

• Who it’s for: managers and owners in SES territory who want guest reports solved without adopting an entire suite.
• When to pick something else: if you need Mossos or Ertzaintza submission today (ours is in development, and “in development” doesn’t file reports), or if you want payments, upselling and locks in the same package.

Chekin

The broadest product on the market: online check-in, biometric verification, payments and deposits, upsells, tourist taxes and smart locks. Its official figures page, with data as of May 2026, claims more than 45 countries with active service and direct legal integration in 18 of them⁴. In Spain it covers SES.HOSPEDAJES, the Mossos, the Ertzaintza and the TURESPAZO return in Galicia too.

• Who it’s for: operators with an international portfolio, or those consolidating everything with one vendor.
• Worth knowing: pricing grows per unit and per module, and the contract minimum is tied to how you pay: the monthly subscription starts at 3 accommodation units while the annual one takes a single property⁴. For pure compliance you pay for the whole suite even if you use one piece. Plan by plan, with its transaction fees, in our Chekin alternatives comparison.

Check-in Scan

The authority-coverage specialist: SES, Mossos, Ertzaintza and, on top of those, the quarterly TURESPAZO return in Galicia. Its mobile app scans documents on the spot and has been on the market for years.

• Who it’s for: anyone operating across several regions with their own registration systems who needs that coverage today.
• Worth knowing: the experience revolves around in-person document scanning more than remote pre-arrival check-in; if your flow is “the guest fills it in before arriving”, it is a weaker fit.

HolaHuésped

The minimalist: automates SES.HOSPEDAJES for Airbnb and Booking hosts, with automated messages to collect guest data. Simple and cheap to start: their site publishes €5 + VAT per apartment per month, with no minimum and a 15-day trial⁴.

• Who it’s for: the host with one or a few properties who wants SES off their plate with the least machinery possible.
• Worth knowing: SES only (no Mossos or Ertzaintza, and no Galician TURESPAZO return), no PMS integrations, and a small team behind it. If your operation grows, a migration is in your future.

AvaiBook (Fast Check-in)

Not a registration app but a PMS with channel manager (from the idealista group) that includes guest registration as a module, filing to SES, the Mossos and the Ertzaintza from inside the PMS⁷. If you already use AvaiBook, switching it on is the natural move.

• Who it’s for: anyone wanting PMS + channel manager + compliance in one system, and willing to commit to that ecosystem.
• Worth knowing: you sign up for the whole platform; as a standalone compliance piece it doesn’t compete. If you already have a PMS you like, this isn’t your route.

Deciding in two questions: location and scope

1. Where are your properties?
   • In SES territory, which is almost all of Spain and includes Galicia: any of the five works, so compare price and flow.
   • In Catalonia or the Basque Country: from this list, Chekin, Check-in Scan and AvaiBook. Our own integration with the Mossos and the Ertzaintza is in development.
   • With the quarterly TURESPAZO return in Galicia: Chekin and Check-in Scan cover it today and we do not.
2. How much tool do you want?
   • Compliance only: a specialist (us, HolaHuésped).
   • The whole guest journey: Chekin.
   • Full management with a PMS: AvaiBook.

FAQ

Is an app mandatory for filing guest reports? No, an app is not mandatory for filing guest reports: you can do it by hand on the SES.HOSPEDAJES portal. The apps exist because doing it manually for every booking, within 24 hours and error-free, is exactly the kind of task humans are bad at.

Are these tools legal with the Ministry? Yes, these tools are legal with the Ministry: the communication may be filed by a third party authorised by the obliged party, which is exactly what software filing with your credentials does. Responsibility for the accuracy of the data stays with the property.

What if I pick the wrong tool? Picking the wrong tool is low drama: the master data (properties, SES credentials) migrates in an afternoon. The expensive part isn’t switching apps, it’s the time lost filing reports by hand while you decide. Start with the basic automated flow and adjust later.

Which one is cheapest? The cheapest of these five is a specialist rather than a suite, and the two pure-compliance tools land on the same figure: HolaHuésped publishes €5 + VAT per apartment per month, and ours is €5 + VAT per active property per month, both with no minimum and a 15-day trial. Chekin costs more because it does far more than the report, and its monthly subscription starts at 3 accommodation units. With one or two apartments, the minimum weighs more on the invoice than the unit price.
