This white paper explains why global e-invoicing is no longer just a file format topic, but an ongoing compliance process that connects regulation, tax, process design, and data governance – especially for SAP-driven, international organizations. It shows how fast mandates, formats, and transmission channels change across regions, and why “static knowledge” quickly becomes outdated. The guide breaks down the real-world challenges (technical mapping into SAP, regulatory complexity, and cross-functional ownership) and outlines what a sustainable approach looks like: continuous monitoring, impact assessment, controlled change, testing, and rollout. For readers, the value is clear: you get a pragmatic blueprint to stay compliant while boosting automation and transparency with structured invoice data inside SAP.
