What it does today

Everything between the request and the arrival.

Airbnb and Booking.com keep bringing bookings. Kapital Keys handles your direct bookings and everything guests and the law ask for around them.

Your own booking site

Your domain, your photos, your rules. Guests see the price of their stay before they ask.

  • Seasonal prices, minimum nights, arrival and departure days
  • Weekly and monthly discounts
  • Tourist tax worked out apart
  • Requests by WhatsApp or e-mail

Requests and direct sales

Every request is logged, with the estimate worked out from your rules, until it is confirmed or lost.

  • Proposal with the dates held until payment
  • Deposit by bank transfer to your IBAN
  • Conversion, direct revenue and direct share of nights

A calendar without double bookings

Imports your Airbnb, Booking.com and Vrbo calendars and publishes your own.

  • iCal sync
  • Overlapping dates refused by the system
  • Availability on your site

Online check-in and SIBA

One link per booking. Each guest fills in their details on their phone, in English, Portuguese or Spanish.

  • Filed with SIBA (AIMA) using your access key
  • Arrival time and extras requests
  • Also opens with the Airbnb booking code

Invoice details

Guests who need an invoice with a tax number add their details; everyone else gets a final-consumer invoice. Kapital Keys never issues invoices.

  • Portuguese tax numbers checked on the spot
  • Lines ready for Portal das Finanças, each with its VAT
  • Tourist tax on its own fatura-recibo

Team and cleaning

Cleaning, maintenance and schedules on the phones of the people who work with you.

  • Each person's list for the day
  • Faults with photo and status
  • Team schedules
From request to arrival

One request from your site, from first contact to invoice.

An example with the figures the system works out. The host decides at every step; Kapital Keys does the maths and keeps the record.

  • Price worked out from your rules, not by hand
  • Dates held only while you wait for payment
  • SIBA and invoice details collected before arrival

FAQ

What hosts ask us first.

Do I have to leave Airbnb or Booking.com?

No. They keep bringing bookings as they do today. Kapital Keys imports their calendars, publishes yours and handles the bookings that come through your site.

Does Kapital Keys issue invoices?

No, on purpose: issuing invoices in Portugal needs certified software. Kapital Keys prepares the details (who to invoice, the tax number, the lines with their VAT and the tourist tax apart) so you can issue the fatura-recibo in Portal das Finanças or in your invoicing program.

Do guests pay through Kapital Keys?

No. Guests pay by bank transfer to your account. We never touch the money: you mark the payment as received and the booking is confirmed.

How does SIBA filing work?

It uses your AIMA access key, stored encrypted. When a guest’s details are complete they go to SIBA, and the result is recorded on the booking.

What if a guest doesn’t want to give invoice details?

They don’t have to. Without details the invoice is made out to a final consumer. Guests who need an invoice with a tax number, above all companies, add their details in the same check-in link.

Where is the data kept?

In the European Union (Supabase, Frankfurt). Invoice details are kept for the 10 years Portuguese tax law requires, then deleted. We don’t sell or share data.

Who is behind Kapital Keys?

João Galhardo, in Tavira (Galhardo.cloud), who already builds the software Algarve accommodation businesses run on every day.
