AI-powered invoice reconciliation for instant clarity and control

Donnerstag.ai is a finance-operations automation platform that helps suppliers reconcile invoices, credit memos, and open items with unprecedented speed and accuracy. Designed for companies dealing with high-volume, error-prone billing workflows, the platform eliminates manual spreadsheet processes and gives teams a real-time view of what has been paid, what is outstanding, and where mismatches occur. The result is faster month-end closes and significantly fewer disputes across the supply chain. Using proprietary AI models, Donnerstag.ai automatically ingests invoices and credit notes from any format, identifies discrepancies, and flags mismatches before they become costly problems. The system integrates directly into existing ERP environments, allowing finance, logistics, and operations teams to maintain clear cash-flow visibility without adding new complexity. Its precision, speed, and ease of use reduce operational friction for shared-service centres and mid-market suppliers. Emerging from the KMU24 group, Donnerstag.ai reflects a shift toward deeper digitisation within supplier finance—bringing automation to a critical but historically overlooked process. By reducing reconciliation times from hours to minutes, the platform strengthens supplier–customer relationships and ensures companies remain audit-ready at all times.
