Developments in electronic invoicing

Electronic Invoicing in Greece is a constantly evolving landscape, and the continuous changes make it a puzzle for the average Greek business. Driving these developments is the Independent Authority for Public Revenue (AADE), which frequently introduces new requirements—each adding another piece to the puzzle of what one might envision as the full digitization of invoicing between companies (and not only).

The vision is ambitious, and there are certainly points to comment on regarding the implementation. However, we must acknowledge that the final destination is legitimate and desirable: reducing tax evasion and moving toward digitalization and simplification of procedures.

A new issue that recently came to light (though not widely publicized) is AADE’s new plan to implement a unified method for the recipient-side retrieval of electronic invoices.

E-ON, as an Electronic Invoicing Provider, is moving forward to deliver a reliable solution for AADE’s new objective of establishing a unified method for recipients to receive electronic invoices.

Until now, all efforts were focused on enabling the supplier to issue an invoice, have it authenticated by the Provider, and send it to myDATA. Now, more detailed planning is being done on the “other side” of the workflow: a unified method for all Providers to make available to the recipient the “electronic equivalent” of the invoice—meaning a machine-readable form, not merely a PDF sent via email (nor, of course, AADE’s well-known “summary,” which falls far short of being a complete electronic invoice).

Once implemented, this component will offer real value to the recipient, who will be able, in a standardized way, to receive all invoices from all suppliers and automatically import them into their own ERP or accounting system. This will result in genuine reductions in cost and errors—issues that today burden corporate accounting departments, both small and large.

E-ON, as an Electronic Invoicing Provider, is naturally starting from the core requirement of delivering electronic invoices according to AADE’s new specifications. At the same time, however, it aims to build the “other side of the bridge” and provide a reliable solution for our corporate client’s challenge of receiving electronic invoices. Such an integration will soon validate E-ON’s vision of a unified system combining ERP functionality and electronic invoicing—rather than a tangle of complex connections between ERP “A,” electronic invoicing “B,” and, eventually, an incoming-invoice processing system “C.”

E-ON’s electronic invoicing service is powered by a proven web-based platform for commercial and accounting applications (known in the market as “ERP”) under the commercial name E-ON RIX. With the broad rollout of electronic invoicing set to begin in 2026, you should start the adoption process immediately—but not with “bare minimum,” oversimplified solutions. Choose a holistic approach, because in the future, the cost of having to “undo and redo” will be much higher!
