Entropy ImmoManager

ImmoManager is the property management solution for private landlords and self-managing homeowners' associations (HOAs) – no subscription, no cloud, no monthly fees. Buy it once, use it permanently.

🏠 Utility Billing
Enter expenses as chargeable or non-chargeable and generate a print-ready statement for your tenant with a single click. Balances and allocations are calculated automatically – including pro-rata billing for tenant changes during the year.

🏢 Homeowners' Association Management
Create HOAs with any number of units and owners. Calculate maintenance fees and reserve funds for each unit, and allocate expenses according to co-ownership shares or living space. Maintenance fee statements and reserve accounts – ready to use as PDFs.

Declaration of Division Import: The AI ​​reads your declaration of division and automatically imports all units.

🧮 TAX OVERVIEW (Schedule V)
Income and deductible expenses per property and tax year – broken down by expense type, as a PDF for your tax advisor or directly for Schedule V.

📷 AI RECEIPT ANALYSIS
Upload photos or PDFs of invoices – the AI ​​automatically recognizes the amount, date, and category. Supports four providers: OpenAI (GPT-4o), Anthropic Claude, Google Gemini, and Mistral. Pay-per-use – no separate AI subscription required.

📋 LEASE AGREEMENT ANALYSIS
The AI ​​reads your lease agreement and extracts all clauses regarding apportionable costs and special agreements. The AI ​​assistant accesses this information for every answer.

💬 AI ASSISTANT
Questions about tenancy law, utility billing, and statements of account directly in the app – the assistant knows your expenses, tenant data, and the analyzed lease agreement.

Dedicated area for holiday rentals: expenses, annual tax overview, receipt package as a ZIP file.
