Which solution best fits your rental?

Learn about Gesar (Improxy)

Improxy is a Portuguese company with more than 25 years in the market, best known for Gecond condominium management software. Gesar is its rental management module, aimed at property management companies rather than individual landlords.

When to consider Aluseg

Gesar is one of the few Portuguese tools confirmed to communicate directly with the Portuguese Tax Authority. However, it is designed for property management companies, with non-public pricing and a sales-led process, rather than individual landlords who want to start in minutes without speaking to sales.

To be fair, Gesar is one of Portugal’s longest-standing tools and one of the few confirmed to communicate with the Portuguese Tax Authority. Aluseg differs through access: no sales process, no hidden price, a free start in minutes, and a product designed for individual landlords as well as professionals.

Prepare your information and start with one property

1. Gather your information

If you already use Gesar through a property management company, confirm which data — including leases and rent receipts — it can export before managing the rental directly in Aluseg.

2. Add the property

Create your account, add the property and link the lease and tenant.

3. Review and track

Check the amounts, dates and documents before you start tracking the rental.

Still have questions?

Does Improxy’s Gesar communicate with the Portuguese Tax Authority?

Yes. According to Improxy’s public information, Gesar communicates with the Portuguese Tax Authority, making it one of the few Portuguese competitors to confirm this integration.

Is Gesar suitable for an individual landlord, or only for companies?

Gesar is mainly aimed at property management companies, with pricing provided through a sales contact. For individual landlords who want to start independently and for free, Aluseg is the more direct option.
