Invoice bookkeeping that
lands in myDATA.
Cortena reads every supplier invoice, codes it to your Greek chart of accounts and ΦΠΑ, then transmits the myDATA document to AADE. Your team reviews exceptions instead of re-keying lines into the tax platform.

What Cortena adds to AADE myDATA.
myDATA is where Greece records invoices for tax. Cortena is the layer that fills it: capture, coding, approvals, then a clean transmission so your team spends time on judgement, not data entry.
Bookkeeping done for you
Every invoice is read and coded to your accounts, cost centre, and ΦΠΑ rate, then prepared as a myDATA document. You set the control points. Nothing is transmitted without your sign-off.
Scale volume, not headcount
When invoice count doubles, the work does not. Cortena handles around 90% of the volume, so your team moves from keying into myDATA to review, analysis, and the close.
One pipeline into AADE
Inbox, PDF, and e-invoice capture feed the same coding rules. Approved invoices transmit to myDATA without CSV files or a second system of re-entry.
From inbox to AADE myDATA.
Cortena reads invoices from your inbox, codes them to your accounting rules, and transmits myDATA documents after you approve. You control the workflow: reviews, thresholds, and who signs off.
Reads your inbox
Cortena reads incoming invoices from email, upload, and e-invoice formats.
Entity and AFM
Detects the entity, matches the supplier AFM, and routes the invoice to the right books.
Bookkeeping agent
Codes account, cost centre, and ΦΠΑ per line against your rules.
Your workflow
Set approvals, reviews, and thresholds. Everything configurable.
Transmit to myDATA
Approved invoices are sent to AADE myDATA. You keep the last word.
Cortena and AADE myDATA, side by side
Cortena is the operator up front: capture, coding, and approvals. After approval, documents are transmitted to myDATA, the tax record at AADE. We are honest about the line.
The tax record stays inside AADE myDATA. Cortena does the work up front and hands over transmission-ready invoices. It does not replace your accountant or your ERP.
More than uploading XML. Real bookkeeping into myDATA.
Everything you need to move invoices from inbox to AADE. You set the rules. Cortena follows them.
Coding with a confidence score
Cortena learns your chart of accounts and cost-centre logic from historical documents. Every prediction comes with a confidence score, so you see where it is reliable and where it is not.
Your workflow, your rules
You decide who approves, which ΦΠΑ rate applies, and when a document may transmit. Nothing reaches AADE without the control points you set.
Transmit to myDATA after approval
Approved invoices become myDATA documents and are sent to AADE. No CSV round-trip, no second round of keying.
Full audit trail
Every AI decision, every correction, and every transmission is logged. Fully traceable for your accountant and your own review.
Bank reconciliation
Import statements and match payments to invoices. Bank lines land against the same books you coded for myDATA.
Line-item allocation
Cortena splits invoice lines and assigns accounts, cost centres, and ΦΠΑ at line level. You set the guidelines. Cortena follows them.
Agents that learn your rules
Invoices arrive and are prepared for myDATA. Cortena applies your accounting logic consistently and gets better over time.
What you should know about AADE myDATA.
myDATA is the digital books and invoice reporting platform of AADE, the Independent Authority for Public Revenue in Greece. Businesses transmit invoice documents so tax records stay aligned with what was issued and received.
No. Cortena automates the upstream work: capturing documents, coding them, and preparing myDATA transmissions. Your accountant and your ERP stay in place. Cortena does not replace year-end close or tax advisory.
Supplier invoices that Cortena has captured, coded, and you have approved. Transmission happens after sign-off, so you control what AADE receives.
In the EU. Cortena hosts on dedicated servers in Germany (Hetzner). Your financial data does not leave the EU and is never used to train external AI models.
Live in about 15 days, including connection and a short learning period on your historical invoices. After that, Cortena handles around 90% of invoice volume for you.
No. Peppol and XRechnung are other European e-invoice rails. myDATA is the Greek AADE reporting mandate. Cortena already reads European e-invoice formats (UBL, CII, ZUGFeRD) on the way in, then transmits the myDATA document to AADE after you approve.
