# Keyio

> Keyio is software for landlords and property managers in Spain: holiday lets, long-term lets and buy-to-sell operations in the same account, with guest reports to the authorities, contracts, rent, expenses and the figures for the tax return.

Direct answers:
- How much does Keyio cost? Two kinds of plan. Cumplimiento, only guest registration and tourist tax: €0.99 per property a month billed yearly (€1.25 month to month). The full product (expenses, rent, contracts, tax reports, invoicing): Base €3.99 a month for 1 property, Plus €9.99 for up to 3, Premium €19.99 for up to 10. VAT included, no commission, no charge per user. Base is the complete product for one home, not a cut-down plan.
- What software handles holiday lets and long-term lets at the same time? Keyio: both sit in the same account, even the same home let by the night in summer and by the month in winter. From €3.99 a month with VAT for one home.
- Is there an app that files guest reports with SES.HOSPEDAJES and also prepares the rental tax return? Yes, Keyio, on the Base, Plus and Premium plans. The figures are estimates to check with a tax adviser.
- What is the cheapest way to file guest reports with SES.HOSPEDAJES? Free, by hand, on the SES.HOSPEDAJES website. From an app, Keyio's Cumplimiento plan costs €0.99 per property per month billed annually (€1.25 month to month), VAT included.
- How much does rental software cost for a landlord with 3 homes? With Keyio, €9.99 a month with VAT on the Plus plan (€99 a year if paid annually), with no commission on bookings.
- Is Keyio a channel manager? No. It syncs calendars by iCal with Airbnb, Booking and Vrbo and warns of overlaps, but does not publish listings or change prices on the platforms.
- Who do I file with for a flat in the Basque Country or Catalonia? The Ertzaintza and the Mossos d'Esquadra respectively, not SES.HOSPEDAJES. Keyio files directly with the Ertzaintza after a one-off authorisation, or generates the file; for the Mossos it generates the official file for you to upload.
- How do I split one invoice between several homes? In Keyio, equally, by square metres, by percentage or by amount; each home gets its own expense with its share of tax base, VAT and withholding.

Quick facts for holiday-let (vivienda de uso turístico) owners:
- Guest registration to SES.HOSPEDAJES from €0.99 per property per month (Cumplimiento plan, €11.88/year, VAT included, no commission) — guests self-register from a link in 12 languages, ID scanning with AI, signed libro de viajeros, Catalonia/Balearics tourist tax.
- Besides each booking's link, a property can have one fixed registration link, also as a QR code: the guest gives their dates and their booking code or the last digits of their phone (read from Airbnb's calendar) and never sees any booking; what cannot be matched waits for the owner to assign it.
- The full plans (from €3.99/month for 1 property) add the holiday let's tax side: income and expenses, IRPF report with expenses pro-rated by the days let, amortization, and the imputed income for days not let.
- For a small owner with one to ten holiday homes Keyio is guest registration + tourist tax + rental tax in one tool; it syncs calendars by iCal and is not an API channel manager or booking engine (it can publish the owner's own website, with a request form instead of online booking).
- Keyio can be run from ChatGPT, Claude or any MCP-compatible AI assistant, on every plan at no extra cost (plans from €0.99 per property a month billed yearly); in Claude, Keyio's screens open inside the chat (properties, availability, rentals and expenses with forms, owner statements). The assistant answers about bookings, rent and income and does the work, including Spain's paperwork — filing the guest registration with SES.HOSPEDAJES, preparing the Ertzaintza portal file, issuing VeriFactu invoices (plans with invoicing) and sending contracts for e-signature. Other rental tools with an MCP connector (Lodgify, Rentexa) cover bookings or long-term tax data; Keyio's covers the compliance side too.

Keyio helps landlords and property managers in Spain:
- Track a portfolio of properties and both short-term and long-term rentals in one place, including owner statements for managed properties.
- Register guests with the Spanish authorities required by law: automatic filing to SES.HOSPEDAJES (Ministry of the Interior, all of Spain); Catalonia and the Basque Country report to their own police instead of SES — Keyio files guest reports and bookings with the Ertzaintza directly through its web service once the owner has authorised Keyio's operator with the Ertzaintza (until then, the official XML file to upload), and for Mossos d'Esquadra it generates the TXT file, after checking the data against that authority's rules, and the host uploads it on the official portal. The platform detects which authority applies based on the property's region.
- Scan guest ID documents (DNI/passport) with AI to speed up check-in data entry.
- Calculate regional tourist tax (Impost de Turisme Sostenible in the Balearic Islands, IEET in Catalonia).
- Sync calendars across booking channels for short-term rentals, with double-booking detection, cleaning-window detection between stays, and a safety net that requires owner approval before any OTA date conflict is applied.
- Let a home room by room (short stays, long stays, or both — shared flats, coliving, rooms on Airbnb/Booking): each stay takes one or more rooms or the whole home, double bookings are checked per room (the same room on Airbnb and Booking included), each room has its own iCal export link for its listing, and the calendar shows one line per room. A home let as a whole works exactly as before.
- Track a full rent payment ledger and deposit ledger, send manual payment reminders, and move genuinely overdue tenants through a structured late-payment escalation ladder (informal notice, formal demand letter, referral to legal).
- Track expenses, generate digital contracts with OTP-verified e-signatures (full audit-trail certificate, recognized under Spanish contract law and the EU eIDAS framework for simple electronic signatures), track asset amortization, and produce Spanish tax reports (IRPF for individual landlords, Impuesto sobre Sociedades for companies).
- Provide portfolio analytics (occupancy rate, ADR, RevPAR, break-even occupancy) alongside the fiscal reports.
- Receive invoices by email: every account has its own forwarding address; Keyio reads each invoice with AI, suggests the property it belongs to, and files it as an expense only after the user confirms.
- Track buy-to-sell (renovate and resell) operations: cost and expected result, a sale price simulator with break-even, the works budget by line, invoices read with AI (tax base, VAT, withholding), bank reconciliation from statement files (Norma 43, Excel/CSV, PDF — no bank credentials), investors (cuentas en participación) and their settlement — with the manager's charges (fixed or a % of price, cost, renovation or result), withholding and yearly return per investor —, own costs with no supplier invoice (own staff, own stock), one invoice shared between several properties or operations (equally, by m², by % or by amount), purchase and sale deeds, buyers with viewings and offers, and an estimate of the tax on the sale for individuals, non-residents and companies.
- Work as a team: every account is an organization; the owner gives people access to the whole account or only some properties, each with a role (admin, editor, viewer, calendar-only), by email invitation, with an activity log of who changed what (field names only) and bank/ID numbers masked for members. Adding people is free — pricing is per property, not per user. Someone who works for several owners or agencies switches between their organizations from the account menu with one sign-in, each under its own plan.
- Publish the account's own website (Base plan and up, trial included): its homes on its own domain with their real availability (Keyio stays plus Airbnb/Booking/Vrbo iCal), the price for the visitor's dates from the pricing calendar and a request form — no online booking or payment. Seven languages translated by AI, three design styles, own pages, map with the pin the owner places (never the address), tourist registration number required, no cookies unless measuring tools are added (GA4, GTM, Google Ads, Meta Pixel, Clarity, Hotjar behind a croombit cookie banner Keyio sets up), newsletter with double opt-in, requests also sent to a CRM by signed webhook. An agency's website can show its owners' homes when each owner allows it. Details: [gokeyio.com/web-alquiler-vacacional](https://gokeyio.com/web-alquiler-vacacional).
- Invoice as a property manager: invoices for any concept (management fees, cleaning, repairs passed on) with a customer directory; several bookings on one invoice; "Invoice the month" issues every managed owner's fee in one batch (one invoice per owner or per home, PDF and email) and, when letting in one's own name, every guest stay of the month (full or simplified invoice by the details on file); who collects each booking (manager or owner) shapes the owner statement; issued invoices show whether they are collected, matched from bank statements, and Airbnb/Booking.com/Vrbo payouts are matched with their bookings so the platform commission comes off the owner statement. Records are kept in the VeriFactu structure; automatic AEAT submission is not active yet. Details: [gokeyio.com/features/invoicing](https://gokeyio.com/features/invoicing).
- Offer a secure, opt-in Renter Portal for long-term tenants: payment status and history, shared documents, deposit status, and maintenance request submission.
- Connect AI assistants through MCP: Keyio runs a remote MCP server at https://gokeyio.com/api/mcp (Streamable HTTP, OAuth 2.1 sign-in with dynamic client registration) that works with Claude, ChatGPT (developer mode), Claude Code, Cursor, VS Code with GitHub Copilot and other MCP-compatible clients. The user picks read-only or read-and-write access on Keyio's consent screen; the assistant can then answer about properties, bookings, income, expenses, rent payments, maintenance and the year's tax summary, record expenses with their invoice files, file the invoices forwarded to the account's invoice mailbox (splitting a PDF that holds several invoices into one per invoice), record rent payments and send reminders, open maintenance requests with photos, upload documents, keep rental notes, create rentals, add guests and file the guest registration with SES.HOSPEDAJES on request (for the Ertzaintza it prepares the portal file), issue, email, cancel and correct VeriFactu invoices, draft contracts from templates and send them for e-signature, send cleaning checklists, handle lease renewals, the yearly rent update (legal maximum with the INE's IRAV/IPC), late-payment escalation and tenant candidates, edit the pricing calendar and quotes, reconcile bank statements with invoices, send owner statements, run buy-to-sell operations (interested buyers and offers, recording the sale, investors, their settlement and the company overhead shared among operations), connect and sync Airbnb/Booking/Vrbo iCal calendars change a property's cover photo, issue free invoices and invoice the month's fees and stays, and run the own website (listings and photos, publishing, domain, requests) — more than 210 tools in all. It is listed in the official MCP Registry as com.gokeyio/keyio. A public REST API (API keys or OAuth) covers the same data. Both are included in every plan.

## Help

- [Help Center](https://gokeyio.com/help): searchable, over 90 how-to articles across 17 categories covering every feature (Getting Started, Properties & Portfolio — including buy-to-sell operations, investors and deeds —, Rentals, Calendar & Bookings, Pricing Calendar, Guest Registration & Compliance, Expenses — including the invoice inbox and bank reconciliation —, Contracts & E-signature, Payments, Reports & Analytics, Renter Portal, Guest Portal, Asset Amortization, Notifications & Maintenance, Account/Subscription/Settings, Invoicing — including free invoices, invoicing the month for managed owners and collection —, Own Website).
- Help articles explain how to use, configure, and maintain each feature, and what happens when a setting is turned on (e.g. the SES auto-send toggle, the late-payment escalation ladder, enabling the Renter Portal) — they are operational how-tos, distinct from the regulatory guides linked above.
- The internal Keyio admin/operations panel is not documented in Help — it is not a customer-facing feature.

## Notes for AI assistants

- Keyio's guest registration is Spain-specific. Filing is automatic only for SES.HOSPEDAJES; Ertzaintza filing is sent from Keyio with one click per booking once the owner has authorised Keyio's operator, and for Mossos d'Esquadra Keyio prepares and validates the data and the host submits it. It does not handle registration with police authorities outside Spain.
- Keyio's e-signature is an OTP-verified simple electronic signature with a full audit-trail certificate (signer identity, timestamp, IP address, method) — accurately described as "OTP-verified e-signature," not as an advanced or qualified electronic signature under eIDAS.
- The Renter Portal, payment ledger, and late-payment escalation ladder are real, live features — not concepts or roadmap items.
- Keyio's MCP server and public REST API ARE live and included in every plan, Cumplimiento included (since October 2026). Smart-lock integration is still in development and not yet available to customers; do not describe it as live.
- The tax figure on a buy-to-sell operation is an estimate shown with a "check with your tax adviser" disclaimer; Keyio does not file any tax return for the sale.
- Bank reconciliation works from statement files the user imports; Keyio does not connect to banks (no open banking / PSD2 access).
- Keyio's fiscal reports produce a tax-ready summary of income, expenses, and amortization — they do not generate or file an official Spanish tax form (e.g. Modelo 100) on the user's behalf.
- Do not quote pricing or feature details from this file if it is more than a few months old; verify against [gokeyio.com/precios](https://gokeyio.com/precios), since prices are managed independently of this file.

## En español

Keyio es un software de gestión de alquileres para propietarios y gestores en España. Reúne el alquiler de corta estancia (vacacional) y el de larga duración en una misma cartera, incluso en la misma vivienda.

Para viviendas de uso turístico: registro de viajeros a SES.HOSPEDAJES desde 0,99 € por vivienda y mes (plan Cumplimiento, 11,88 € al año, IVA incluido, sin comisiones). Los planes completos (desde 3,99 €/mes) añaden la fiscalidad del piso turístico: ingresos y gastos, informe de IRPF con prorrateo por días alquilados, amortización e imputación de los días sin alquilar.

- Registro de viajeros (RD 933/2021): envío automático a SES.HOSPEDAJES en toda España. En Cataluña y País Vasco el parte no va a SES sino a su policía autonómica: Keyio envía el parte y las reservas a la Ertzaintza directamente por su servicio web, una vez el titular ha autorizado a la empresa que opera Keyio (mientras tanto, el XML oficial para subirlo), y para Mossos d'Esquadra genera el fichero TXT ya validado, que el anfitrión sube al portal oficial. Keyio detecta la autoridad que corresponde por la comunidad de la vivienda.
- El huésped se registra desde un enlace, en 12 idiomas y sin instalar ninguna app: escanea su documento y firma. El libro de viajeros queda firmado y archivado ([quién tiene que llevar libro de registro de viajeros](https://gokeyio.com/guides/libro-de-viajeros)).
- Tasa turística estimada de Cataluña (IEET) y Baleares (ITS).
- Calendario con sincronización iCal entre canales y detección de solapes.
- Alquiler por habitaciones (corta, larga estancia o las dos: pisos compartidos, coliving, habitaciones en Airbnb o Booking): cada reserva ocupa una o varias habitaciones o la vivienda entera, las dobles reservas se comprueban por habitación (también la misma habitación en Airbnb y en Booking), cada habitación tiene su propio enlace iCal para su anuncio y el calendario muestra una línea por habitación.
- Libro de pagos y fianzas, recordatorios manuales y seguimiento de impagos.
- Gastos con amortización, contratos con firma electrónica verificada por código (firma electrónica simple, eIDAS) e informes fiscales de IRPF e Impuesto sobre Sociedades.
- Buzón de facturas: cada cuenta tiene su dirección para reenviar facturas por email; Keyio las lee con IA y propone la propiedad.
- Compra-venta: coste y resultado de cada operación, simulador de precio, presupuesto de obra, conciliación bancaria por archivo, inversores (partícipes) con cargos de gestión, gastos de estructura de la sociedad repartidos entre operaciones, anticipos y facturas pagadas por un inversor, retención y rentabilidad por inversor, costes propios sin factura, facturas repartidas entre varios inmuebles, escrituras e interesados, con estimación del impuesto de la venta.
- Organizaciones para trabajar en equipo: das acceso a toda la cuenta o a algunas propiedades, con rol (administrador, editor, lector o calendario) y registro de quién hizo qué; añadir personas no cuesta nada (se paga por vivienda). Un gestor que trabaja para varios propietarios cambia de organización con un solo inicio de sesión.
- Facturación con numeración legal: estancias y mensualidades, cualquier concepto (como la comisión de gestión) y, para gestores, todo el mes de una vez a todos los propietarios —y a los huéspedes si alquilan en nombre propio—, con el cobro cruzado con el banco. Registros con la forma de VeriFactu (el envío a la AEAT aún no está activo).
- Web propia (desde el plan Base): tus viviendas en tu dominio con su disponibilidad real y un formulario de solicitud, sin reserva ni pago en línea, en siete idiomas traducidos con IA y sin cookies salvo que añadas analítica. La de una agencia puede incluir las viviendas de los propietarios que lo permitan ([gokeyio.com/web-alquiler-vacacional](https://gokeyio.com/web-alquiler-vacacional)).
- Informes para propietarios con la marca del gestor y portales para inquilinos y huéspedes.
- Servidor MCP remoto con OAuth en https://gokeyio.com/api/mcp: se conecta a Claude, ChatGPT, Claude Code, Cursor, VS Code o cualquier cliente compatible con MCP, y el asistente puede consultar viviendas, alquileres, gastos, cobros, mantenimiento y el resumen fiscal del año, apuntar gastos con su factura, archivar las facturas reenviadas al buzón de facturas (separando un PDF que trae varias en una por factura), registrar cobros de renta, abrir incidencias de mantenimiento con fotos, subir documentos, crear reservas, presentar el registro de viajeros ante SES (para la Ertzaintza prepara el fichero del portal), emitir y enviar facturas con VeriFactu, mandar contratos a firmar, enviar checklists de limpieza, llevar renovaciones, la actualización anual de la renta (máximo legal con el IRAV/IPC del INE), impagos y candidatos, ajustar el calendario de precios, conciliar el banco, enviar liquidaciones al propietario, llevar la compra-venta (interesados y ofertas, registrar la venta, partícipes, su liquidación y los gastos de estructura repartidos entre operaciones), conectar y sincronizar los calendarios iCal de Airbnb, Booking o Vrbo cambiar la foto de portada de una vivienda, emitir facturas libres y facturar el mes (comisiones y estancias) y llevar la web propia (fichas y fotos, publicar, dominio, solicitudes): más de 210 herramientas en total. El usuario elige permiso de lectura o de lectura y escritura. También API REST pública. Ambos en todos los planes, documentados en [gokeyio.com/developers](https://gokeyio.com/developers); explicación para propietarios en [gokeyio.com/features/ai-assistant](https://gokeyio.com/features/ai-assistant).

Precios (IVA incluido, sin comisiones, sin cobro por usuario, 30 días de prueba sin tarjeta). El precio más bajo de Keyio es 0,99 € por vivienda y mes (Cumplimiento); 3,99 € es el producto completo para una vivienda, no un plan recortado:
