Winfinans scales e-invoicing through Semantic’s REST API to Peppol and Nemhandel

Winfinans is known for delivering powerful, cloud-first finance and ERP capabilities to ambitious organizations. As Danish and EU requirements evolved, Winfinans wanted to deepen its native support for compliant e-invoicing and e-procurement—without diverting core engineering away from its product roadmap. The brief was clear: achieve robust, future-proof connectivity to Peppol and Nemhandel with minimal operational overhead, maximum reliability, and full control from inside Winfinans.

Semantic implemented a strategic REST-API integration that exposes Peppol and Nemhandel capabilities as standard, versioned endpoints. The approach decouples transport, validation, and compliance logic from Winfinans’ application layer, so product teams can orchestrate e-invoicing and document exchange with simple, idempotent calls. Built-in monitoring, retry logic, and standards updates handled by Semantic’s platform reduce maintenance and eliminate one-off adapters. The result is a unified, testable pathway for UBL documents and related business messages, ready for both B2G and B2B flows.

Time-to-value was immediate. Winfinans can now onboard customers to Peppol and Nemhandel faster, cut the cost of keeping pace with BIS and CIUS changes, and offer a cleaner developer experience across its ecosystem. Partners benefit from consistent API behaviors, while finance users experience reliable, compliant delivery baked into their daily workflows—no middleware sprawl, no fragile point-to-point integrations.

“Semantic provides Winfinans with a strategic REST-API interface to Peppol and Nemhandel.” — Jacob Walsøe, CEO at Winfinans
