Greek authorities have postponed the mandatory B2B e‑invoicing go‑live to 2 March 2026, with a two‑month soft‑launch ending in early May.

Penalties for non‑compliance include VAT‑based fines and fixed €500/€1,000 penalties, and businesses must submit a commencement declaration to AADE before issuing e‑invoices.
