Foreign guest registration
Every guest from abroad, babies included, needs a boletim de alojamento within three working days of arrival. Areca builds the SIBA file from the details taken at booking or check-in.

Property management software
ready for Portugal
Areca asks each guest for what the SIBA bulletin needs, writes the file for AIMA, counts guests and nights by country for INE and adds the taxa turística to every stay. Your calendar, OTAs and booking engine sit in the same place.

What Portugal asks of you, and where Areca helps
Four duties come with running guest accommodation in Portugal. Areca covers three of them today, and the fourth is on its way.

Monthly guest statistics
Properties in the INE survey of tourist accommodation send their guests and nights each month, split by country of residence. One report gives you all of it for any month you pick.

Taxa turística
Lisbon, Porto and a growing list of municipalities charge a fee per person and night. Set the amount, the night limit and the age exemption once, and each booking carries it.

Certified invoicing
Fiscal invoices in Portugal come from AT-certified software or the Portal das Finanças. We are connecting Areca to certified invoicing. Until then, keep issuing them where you do today.
Setting it up takes a few minutes. Our Portugal setup guide walks through each screen.
SIBA for AIMA
See at a glance who still needs a bulletin
The guest list labels each foreign guest as to report, missing data, reported or dates changed, and leaves Portuguese guests out. One click writes a numbered .DAT file with everyone who is ready, and you upload it on the SIBA website.
File numbering
Carry on from your old software
SIBA takes a file only when its number is higher than the last one it received. Type in the next number once and Areca continues the sequence. If an upload comes back refused, correct the guest in the booking and download the same file again with the fix inside.
From arrival to AIMA
Three steps, nothing typed twice
Guest details are entered once, by the guest or at the desk, and reused in every file.
Ask for the right details
For a property in Portugal, the check-in form already requires nationality, date of birth, ID document and country of residence for each guest.
Export the file
Choose the dates and export. Guests with an empty field stay out of the file and are listed, so you know whom to ask.
Upload on SIBA
Send the file on the SIBA website. Sending bulletins to AIMA straight from Areca is coming soon.
INE and taxa turística
Monthly numbers without counting by hand
Pick a month in Guest statistics and Areca adds up adults, children and guest nights, then splits them by country of residence. A stay that runs from one month into the next counts only the nights that fall in each month.
- Country of residence is required at check-in, so no guest goes uncounted.
- The taxa turística charged that month sits in the same report, ready for the municipality.
- Download it as Excel or CSV for your accountant.

Frequently asked questions
Not yet. Areca writes the SIBA file and you upload it on the SIBA website. Sending bulletins straight to AIMA is coming soon.
No. SIBA covers guests from abroad, so Areca marks Portuguese guests as not required and keeps them out of the file. Everyone else is reported one by one, children and babies too.
Fix the guest's details in the booking and download the same file again from the SIBA settings. It keeps its number and carries the corrected details. A file exported by mistake and never uploaded can be discarded, and its number is reused.
Yes. In the SIBA settings, enter the number that follows your last file and Areca continues from there. Your NIF and establishment number go in the same screen.
Open Reports, then Guest statistics, and choose the month. You get guests and guest nights in total and per country of residence, plus the tourist tax charged in those dates.
