Electronic invoice in Greece

This page provides an overview of the requirements, formats, and data fields used for electronic invoicing in Greece.

Legal Background & Requirements

For B2G:

Since January 2020, all public sector entities in Greece must be able to receive e-invoices.
Greece follows the EU Directive 2014/55/EU and implements the EN 16931 semantic standard.
Electronic invoices to public sector buyers must be submitted via PEPPOL.

For B2B:

Electronic invoicing in B2B is voluntary, but electronic reporting to the tax authority (AADE) via myDATA is mandatory.
myDATA is not an e-invoicing platform, but all invoice data must be reported there.
Some certified service providers combine both: PEPPOL delivery + myDATA reporting.

How to Send E-Invoices in Greece (Cross-border & Domestic)

We support cross-border e-invoicing via PEPPOL BIS Billing 3.0, compliant with EN 16931. On the right is a typical B2G scenario.

E-Invoicing Greece Flow

Cross-border invoices (B2G or B2B): Sent via PEPPOL BIS format through Access Points between EU countries.
Domestic invoices (mainly B2B): Sent via Faktur-X or hybrid formats through national providers.
All domestic invoices must be reported to MyData, which forwards the summary to the Greek tax authority (AADE).

Supported Formats

PEPPOL BIS Billing 3.0 (UBL 2.1) – required for B2G
EN 16931 compliant XML – semantic standard for structured invoices
Attachments (PDF, contracts, etc.) allowed as additional files, not as invoice base
