- Automatic submission to SEF upon host approval
- Real-time submission status — Pending · Submitted · Confirmed

- Each rule scoped to the properties it actually affects
- Recommended next actions, ranked by severity
Live

Operations Layer
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.
- Auto-generated cleaning tasks from check-out dates
- Lockbox codes & wifi shared with guests just-in-time
- Mobile cleaner app with photo proof + audit log

About
From the Bay Area to Nazaré.
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.
