THE STATE OF HOSTING IN PORTUGAL
the legal deadline to report every guest (SIBA).
a missed AL obligation is a contraordenação under DL 128/2014.
Lisbon's tourist tax — every concelho sets its own.
ALerta automates the parts that put you at risk — and shows you the parts you still need to do.
WHAT ALERTA DOES
EVERY PROPERTY IS DIFFERENT
One dashboard that adapts to each property — track AL licenses, insurance, safety certs, and SIBA in a single calm view. Configure once, monitor forever.

3 WORKING DAYS. EVERY GUEST. ZERO GUESSWORK.
ALerta automates the entire SIBA loop — your guest receives a unique form, fills it out, and we submit it to SIBA (now under AIMA) on your behalf the moment you approve. No more login portals. No more deadline anxiety.

PORTUGAL'S AL RULES CHANGE. EVERY. SINGLE. QUARTER.
ALerta's intelligent layer scans Diário da República, EU directives, and 40+ municipal ordinances — then matches each new rule to your specific properties and tells you exactly what to do next.

IRS DEADLINES. SIMPLIFIED REGIME MATH. NO ACCOUNTANT IN YOUR KITCHEN.
Per-property income tracking, IRS deadlines surfaced when they matter, and one-click exports your accountant will love. Simplified regime aware, multi-year, ready when you are.

CLEANERS DON'T HAVE LAPTOPS. GUESTS DON'T READ EMAILS. THINGS SLIP.
ALerta coordinates everything between bookings — cleaners get tasks on their phones, guests get wifi and lockbox codes when they arrive, and you get incident alerts when something needs your attention.

I'm a Brazilian-American who grew up in the SF Bay Area working in Tech. Years ago, my family fell in love with Portugal — and my father and I, on a father-son trip, bought a small apartment in Nazaré to rent out.
While researching how to rent it out, we hit the wall every AL host hits: SIBA, AL licensing, IRS, and municipal rules. I'd worked on large SaaS implementations for years — and I still felt overwhelmed. The only way to keep track of it all was spreadsheets, calendar reminders, and a handful of disconnected tools.
So I built ALerta. The all-in-one tool every Portuguese AL host deserves. Alongside Airbnb and Booking.com on every host's home screen — calm dashboard, less anxiety, built by someone who lives this too.
