- A global company with invoices in many languages and messy scans, where extraction accuracy is the bottleneck and the ERP already handles payment.
Pick Rossum if
- Enterprise AP shared service centers processing supplier invoices from many countries and languages into SAP S/4HANA or Coupa.
- Coupa customers who want template-free capture and master data validation in front of Coupa invoicing, now from the same parent company.
- European entities facing 2026 and 2027 e-invoicing mandates that must process Peppol, KSeF or FatturaPA files next to PDFs in one queue.
