Aluseg

Aluseg helps individual landlords in Portugal manage their rentals legally and without paperwork.

Letting a property in Portugal comes with recurring obligations toward the tax authority (AT):

• registering the lease (Modelo 2);
• issuing monthly electronic rent receipts;
• paying stamp duty;
• applying the annual rent update on time.

Rules change often, and mistakes lead to fines of €150–3,750. Most landlords own one to three properties and handle this with spreadsheets, or pay an agency 8–10% of the rent.

Aluseg covers the whole landlord workflow:

• an NRAU-compliant lease generator;
• automatic sync with the Portuguese tax portal (lease registration and electronic receipts);
• the legal annual rent update with registered-mail letters;
• SEPA rent collection via Stripe;
• e-signature and move-in/move-out inspections;
• tenant solvency checks;
• a partner lawyer for legal acts such as AIMA signature recognition and eviction notices.

Tenants use Aluseg for free, with a contract check and a shareable Tenant Passport, which creates a two-sided growth loop. The app is available in Portuguese and English, and data is hosted in the EU (Frankfurt).
