The Story

We built wynajem.app to help property owners stop juggling contracts, payments, and maintenance requests across scattered documents and endless phone calls. Our all-in-one platform centralizes rental management—from invoicing and tenant payment tracking to utility billing and maintenance reports—so landlords can run their properties efficiently without chaos.

AI Overview

AI-generated

Landlords managing residential or commercial properties typically waste hours moving between spreadsheets, email, text messages, and paper documents to track lease agreements, tenant payments, maintenance requests, and utility charges. Wynajem.app consolidates these scattered workflows into a single system designed specifically for rental property owners in Polish-speaking markets.

The platform's strength lies in its unified data model. Rather than entering property details, lease terms, and tenant information multiple times across different modules, users enter this information once and reuse it throughout invoicing, payment tracking, and maintenance management. This single-source-of-truth approach eliminates the data entry duplication that makes rental management tedious at scale.

The core capabilities cover the full rental cycle. Property owners can configure leases with specific rent amounts, deposit terms, and payment due dates, then generate invoices and payment reminders automatically. The financial dashboard provides real-time visibility into who has paid, who owes money, and whether payments are partial or overdue. The system handles surplus payments intelligently, applying them to future invoices rather than requiring manual adjustments.

What distinguishes wynajem.app from basic spreadsheet solutions is its handling of ancillary rental tasks. The platform recognizes and processes utility invoices using data extraction, allowing owners to split bills and track tenant deposits for shared expenses. A dedicated maintenance module replaces scattered text messages with structured requests that include photos, status tracking, and automatic notifications. Property owners can manage apartments, rooms, commercial spaces, and garages within a single account.

The platform offers an optional tenant portal, but does not require it. Landlords can send invoices via email without setting up tenant accounts, reducing adoption friction. A mobile app is in development for iOS and Android.

The commercial model reflects the product's positioning for small to mid-sized landlords. The pricing is annual and transparent: 100 PLN net per year for the first property, 50 PLN for each additional one, with no per-tenant charges or feature tiers. New users get six months free to evaluate the full platform before committing. No credit card is required to start, lowering the barrier to trial.

The solution addresses a genuine operational pain point for rental property managers who lack the scale to justify expensive property management software. For this audience, wynajem.app trades feature breadth for focused, workflow-aligned simplicity.
