The Belgian government will decommission the Hermes e-invoicing platform on December 31, 2025, following a market review that confirmed its temporary role is complete.
Launched as a fail-safe for businesses not yet ready for Peppol, Hermes ensured invoices could be exchanged during the early stages of digital adoption. With a now mature and competitive e-invoicing market, the government is stepping back in favor of private-sector solutions.
Key deadlines:
-
December 31, 2025: Hermes deactivated
-
January 1, 2026: Mandatory B2B e-invoicing begins
-
March 31, 2026: Last day to consult archived Hermes data
Businesses still using Hermes should begin promptly selecting and implementing an alternative e-invoicing solution to stay compliant with the January 2026 mandate.
