MietCheck Pro is rental-management software for private landlords and small property managers in the German-speaking market — built for everyone still reconciling rent in Excel or from bank statements. At its core is automatic bank reconciliation: you upload your bank statement as CSV (8+ German bank formats plus universal CSV), and incoming payments are matched to the right tenants across several stages (IBAN, alias, amount, name). Unclear payments don't disappear — they surface in a dedicated clearing area. You see in seconds who has paid in full, in part, or not yet. What MietCheck Pro offers: automatic bank import for 8+ German bank formats plus universal CSV; target-vs-actual matching and running balances per tenant; a 24-month payment heatmap — every tenant's payment status at a glance; one-click dunning with multi-stage templates; German lease contracts as print-ready PDFs — included, no extra charge; full functionality on smartphone. Hosted in Germany (Hetzner Nuremberg), GDPR-compliant, with a data-processing agreement (DPA). Built from the founder's own need — he manages around 55 units with it himself. Plans: Basic €19/month (up to 15 units), Pro €49/month (up to 50 units), Business €99/month (unlimited). Cancel monthly, 30-day free trial, no credit card required.
