As published, AADE (Greece's Independent Authority for Public Revenue) has required electronic books and real-time invoice-data transmission through myDATA since 2021, with full real-time reporting obligations enforced from 2024. Separately, structured B2B e-invoicing — issuing the invoice itself in a structured format, not just reporting its data — becomes mandatory in phases: large taxpayers above the 2023 one-million-euro revenue line from 2 March 2026, and all other VAT-registered businesses from 1 October 2026 (as published — confirm current requirements with your adviser).
LATYNEX Digital builds the workflow around the invoice data your myDATA-connected accounting system or e-invoicing provider needs. This page covers it for Athens businesses. The general service is at Workflow Automation & Systems Integration, and the market overview is at LATYNEX Digital for businesses in Athens. Delivery is in English, and this page names no client.
Typical industries
- Small and mid-sized retailers and service businesses
- Wholesalers and distributors invoicing B2B customers
- Businesses above the large-taxpayer line (over one million euros in 2023 revenue)
- Finance and back-office teams preparing invoice data
- Businesses moving from myDATA reporting alone to structured B2B e-invoice issuance
Common lead-handling problems
- Sales recorded in a spreadsheet or ERP export, then re-keyed for invoicing
- Invoice fields split across several tools with no single myDATA-ready source
- No record of which myDATA transmissions AADE rejected, or why
- A missing field found only when an e-invoicing provider rejects a batch
- No internal owner for the shift from real-time reporting to structured invoice issuance
Direct answer
If your Athens business is a large taxpayer facing the 2 March 2026 structured B2B e-invoicing date, or any VAT-registered business preparing for 1 October 2026, LATYNEX can build a workflow that turns your existing sales or billing records into one clean invoice data set, checks it against the fields your myDATA-connected accounting system or e-invoicing provider expects, and gives every rejected or exception invoice an owner before it is resubmitted.
Why the global page and the Athens hub are not enough
The global Workflow Automation & Systems Integration page has no myDATA or phased e-invoicing mandate to design against, and the Athens hub is broad discovery for the market. Here the design point is that myDATA reporting and structured B2B invoice issuance are two separate obligations on two separate timelines, so the invoice data has to be ready for whichever one applies to your business by its date, not conflated into one.
What we configure and build
The work sits before your myDATA-connected accounting system or e-invoicing provider, not in place of it.
- An invoice data workflow pulling from your existing sales, billing or ERP records
- Field checks against the myDATA and structured e-invoice formats your provider confirms
- A queue for rejected or exception invoices, with an owner and a status
- Separate handling for the large-taxpayer and general-business dates, if your group spans more than one entity
- A log of what was prepared, when, and the outcome, plus a written handover
What stays with you and your myDATA provider or accountant
Transmission to myDATA, structured B2B invoice issuance, and any dealings with AADE stay with your accountant, e-invoicing provider or myDATA-connected accounting system. Whether a given invoice meets AADE's current requirements is for you and your adviser; we prepare and check the underlying data, we do not transmit it to myDATA.
What needs API support or custom scope
LATYNEX claims no myDATA integration and no AADE accreditation. Any connection to your myDATA-connected accounting system, ERP or e-invoicing provider is scoped per project through the documented API or export format if access is permitted, after technical review.
What we do not do, and where LATYNEX is not the right fit
LATYNEX does not give tax or legal advice, does not connect directly to myDATA, does not say an invoice is compliant, and holds no Greek tax-authority accreditation. It has no Athens office or named clients, and delivery is in English only. If you already run an ERP with a working myDATA connector, this page is not for you.
How delivery actually works
LATYNEX Digital has no office in Athens and does not claim one. We work with Athens businesses remotely, over video calls and written updates, in English, with the same team and process as in every other market.
Questions
Do you have an office in Athens?+
No. We work with businesses in Athens remotely, over video calls and written updates, in English, and we do not imply a local presence.
Do you connect to myDATA or transmit invoices for us?+
No. Transmission to myDATA and structured B2B invoice issuance stay with your accountant, e-invoicing provider or myDATA-connected accounting system. We prepare and check the invoice data beforehand.
When does structured B2B e-invoicing become mandatory in Greece?+
As published, large taxpayers above the 2023 one-million-euro revenue line are covered from 2 March 2026, and all other VAT-registered businesses from 1 October 2026. Confirm which date applies to you with your adviser.
Is this the same as myDATA reporting?+
No. As published, real-time invoice-data reporting through myDATA has been required since 2021, with full obligations enforced from 2024. Structured B2B e-invoicing — issuing the invoice itself in a structured format — is a separate, later obligation on the 2026 dates above.
Does this make our invoicing compliant?+
No. We give no tax or legal advice and cannot say your invoicing meets requirements. Confirm current requirements with your adviser; we build to the data set they and your provider specify.
How are you invoiced, and in what currency?+
In EUR, by Latynex Trade OÜ, a company registered in Estonia (EU). Tax treatment for a client in Greece is confirmed on the quote, and we do not give tax advice.
