Rentila is one of Europe’s most widely used rental management platforms and still runs an active Portuguese version. It is a mature product with rent accounting, mobile apps and electronic signatures. So why do so many landlords look for an alternative built for Portugal? Mostly because of the Portuguese tax cycle: lease registration and electronic rent receipts with the Tax Authority (AT), Anexo F and the NRAU.
This comparison looks at Rentila, Rentger and Aluseg based on each provider’s public pages, checked on 27 September 2026, including what Aluseg does not do yet.
- Rentila is mature and strong in accounting, e-signature and bank sync, but we found no direct integration with the Portuguese Tax Authority.
- Rentger is free for up to 9 properties and offers eIDAS e-signatures, but it is built for the Spanish market.
- Aluseg is built for Portugal: NRAU leases, tenant solvency checks, SEPA Direct Debit rent collection, AT lease registration and electronic rent receipts, and Anexo F preparation. Free for 1 property.
- Aluseg does not yet offer bank sync; the free accountant portal is available.
What to expect from rental management software in Portugal
- Portuguese law: NRAU-compliant leases, not adapted foreign templates;
- The Portuguese tax cycle: registering the lease with the AT by the end of the month after the tenancy starts, stamp duty, electronic rent receipts and IRS Category F;
- Risk management: checking tenant solvency before signing;
- Portability: being able to take your data with you.
