FLATFLOW is an all-in-one rental property management platform designed for property owners, professional property managers, and sub-renters. It replaces spreadsheets and scattered documents by centralizing contracts, tenants, invoices, payments, and portfolio analytics in a single application.
Core features:
- Contract & tenant management — digital contracts with e-signatures, centralized tenant profiles, multi-property management, and maintenance request handling, all in a few clicks.
- Automated accounting & payments — automatic VAT invoice generation, bank account synchronization, arrears tracking, and direct integration with KSeF (Poland's
National e-Invoicing System). Routine accounting tasks happen without manual input.
- Communication & team tools — automated payment reminders and deadline notifications so no follow-up gets missed. Built-in message translation makes communication
with foreign tenants as straightforward as with local ones. Team and task management for larger operations.
- Analytics & reporting — property-level profitability reports, ROI calculations, rental trend tracking, and side-by-side property comparisons. Make investment decisions based on data, not gut feeling.
FLATFLOW scales from a single apartment to an extensive portfolio without changing plans. Pricing is based solely on the number of properties added - rooms, tenants, invoices, and messages are unlimited.
A free 30-day trial is available with no credit card required and no commitment. Each account includes a dedicated support contact reachable by phone.
