The new way to manage rentals
Smarter, faster, and without manual errors
Forget about manual data entry
Upload any invoice or receipt. Our AI extracts the issuer, date, and amount, and automatically categorizes the expense for your accounting.
Reclaim your time
Cut manual management dramatically. What used to take hours of admin now takes seconds.
Goodbye to manual work
From legally binding e-signatures to automatic police registration reports. Proactive alerts keep you ahead of late payments, contract renewals, and compliance deadlines — all on autopilot.

From the calendar and guest registration to your IRPF and IS filing. All inside — no commissions, no app-switching.

Simple, Transparent Pricing
The only difference between plans is the number of properties you can manage. Every feature is available on every plan.
Except the Cumplimiento plan, which includes only guest registration (with signature and libro de viajeros) and tourist tax.
Flat price, no commission
You pay by number of properties, full stop. Keyio never takes a cut of your rent, your deposits, or upsells to your guests.
Spanish tax reporting included
An IRPF report for individuals and corporate tax for companies, with expenses and depreciation — in the same price, not as an add-on.
No features behind a paywall
E-signature contracts, guest registration, calendar, tenant portal… all of it is on every plan. The only thing that changes is how many properties you manage.
Included in every plan
Only need compliance?
Compliance plan
Legal guest registration —with guest signature and a downloadable libro de viajeros— and tourist tax, priced per property. Add as many properties as you need at the same per-unit price.

Start Your Free TrialFrequently Asked Questions
Everything you need to know about managing your properties with Keyio.
Keyio is an all-in-one property management platform designed for Spanish landlords and property managers. It helps you track rentals, manage expenses, generate tax reports, handle guest registration, and organize contracts — all from a single dashboard.
Yes! Keyio offers a 30-day free trial with full access to every feature — no credit card required to sign up. After the trial, plans start at €3.99/month for 1 property, with higher tiers for more properties and a per-property Cumplimiento plan for guest registration and tourist tax only.
No, Keyio works directly in your browser as a Progressive Web App (PWA). You can also add it to your phone's home screen for a native app-like experience — no app store download required.
Keyio handles the RD 933/2021 guest-registration obligation across Spain. The platform auto-detects your property's region, collects the guest's data (with AI ID scanning and an optional signature), files to the national SES.HOSPEDAJES system automatically, and — where a region requires its own submission channel — prepares everything you need for it. You also get a downloadable libro de viajeros on demand.
Yes, Keyio supports hybrid rental management. You can track short-term vacation rentals alongside long-term leases within the same property portfolio. Each rental type has tailored features — calendar sync and guest registration for short-term, and contract management and a payment ledger for long-term rentals.
Yes. Keyio uses Firebase infrastructure with encrypted connections (TLS/SSL) for all data transfers, and your data is stored securely in Google Cloud with role-based access controls. We never share your information with third parties.
Yes, you can invite collaborators such as accountants, co-owners, or property managers with specific permission levels. Each collaborator only sees the data you choose to share, giving you full control over access.
Yes. Keyio includes a dual fiscal engine: IRPF mode for individual landlords (Rendimientos del Capital Inmobiliario, Modelo 100) and IS mode for legal entities (Impuesto sobre Sociedades — S.L., S.A.). Each mode applies the correct deductions, amortization schedules, and ownership splits, and both generate export-ready reports for your accountant.
Yes. Every signer verifies their identity with a one-time code sent to their email before signing, and once everyone has signed, Keyio generates a certificate recording who signed, when, from which IP address, and by what method — attached to the final PDF. This satisfies Spanish contract law (Art. 1278 of the Código Civil), which recognizes an electronic signature as valid evidence of consent.
Your Reports dashboard shows occupancy rate, average daily rate (ADR), revenue per available night (RevPAR), and break-even days — per property or across your whole portfolio, with year-over-year comparisons — alongside the fiscal reports built for IRPF or IS tax filing.
Yes. For long-term rentals, you can open a secure Renter Portal where tenants log in with a one-time code to see their payment status and history, download documents you've shared, check deposit status, and report maintenance issues. You choose exactly what's visible to them.
Yes. Enable the Guest Portal and Keyio generates a per-booking link with a 4-digit PIN already included in the message you send — check-in/check-out times, the address, an arrival guide with a photo and instructions for each step (parking, entrance, bins…), the booking's entry code, WiFi (one network or several), your local recommendations (restaurants, beaches, activities…), and a way to report an issue. No app, no separate login code to wait for.
Yes, in the two places it matters most for short-term rentals. You can send a check-in reminder over WhatsApp — with the guest portal PIN included — to any guest with a phone number on file. And when you send a maintenance checklist (a cleaning turnover, for example), you can deliver it by WhatsApp instead of email, to one contact or your whole cleaning team, no Keyio account needed on their end. Both are opt-in and require a phone number for that guest or contact.
