EN 16931‑1, the EU e‑invoicing standard, is being updated to a mid‑2026 release that expands B2B functionality and aligns with the ViDA initiative. The revision is not backward compatible, requiring migration for existing version 3 implementations, and will be formally approved in late January 2026 with publication concluding within six months. Key national roll‑outs include Germany’s XRechnung 4.0 and France’s CTC extensions.

The UAE Ministry of Finance has issued new Electronic Invoicing Guidelines, mandating B2B and B2G transactions to use Peppol-based XML invoices from 2027. The rollout is phased: businesses with ≥ AED 50 million revenue go live on 1 January 2027, smaller businesses on 1 July 2027, and government entities on 1 October 2027. The system requires 51 mandatory data elements and real‑time reporting via accredited service providers.
