Global EDI / e-Invoicing Regulatory Digest
Regulatory momentum around EDI and e-invoicing is accelerating worldwide. Governments are tightening rules on digital tax reporting, data security, and interoperability, transforming EDI from a back-office efficiency tool into a compliance cornerstone.
As of late 2025, the European Union, Middle East, and several Asia-Pacific markets are entering new phases of mandatory e-invoicing and real-time data exchange, while the U.S. continues to refine healthcare and federal procurement standards.
