Greece myDATA Invoice
AADE myDATA B2B e-invoicing for Odoo — invoiceUid, MARK & QR on every customer invoice
Connect Odoo to the Greek AADE myDATA platform for the 2026 mandatory B2B e-invoicing waves. Customer invoices and credit notes are transformed into the AADE InvoicesDoc XML, the invoiceUid is computed, the document is transmitted to AADE, and the returned MARK (Mandatory Authentication Registration Number) and verification QR code are stored on the move.
SendInvoices transmission
The InvoicesDoc XML is posted to the AADE myDATA REST API with your own credentials. Developer/sandbox and production endpoints are editable; requests retry with exponential backoff and every call is logged.
invoiceUid + MARK
The 40-character SHA-1 invoiceUid is computed exactly as AADE recomputes it. The MARK and provider authentication code are captured from the response and printed with an AADE verification QR rendered to a PNG.
AADE invoice types & VAT categories
Domestic, intra-community and third-country goods and service types (1.x, 2.x, 5.x) are selected automatically. VAT categories 1-8 cover mainland and island rates, with exemption categories for zero-rated cross-border lines, plus E3 income classification.
Real ΑΦΜ validation
Company and partner Greek VAT numbers (ΑΦΜ) are validated with the official AADE mod-11 weighted check-digit algorithm, catching typos before a document ever reaches AADE.
myDATA business-rule validation
A Greece rule set layered on the engine's EN 16931-style core checks the issuer and counterpart ΑΦΜ, line VAT categories, EUR currency, the invoice series, and credit-note correlation — surfacing issues in a single click before transmission.
Bring-your-own-key & private by design
The AADE user id and subscription key live on your connection record, never bundled with the module. Invoice data is transmitted only to the AADE myDATA endpoint you configure. An onboarding wizard, connection model and optional batch-submission cron complete the package.
Compatible with Odoo 18 and Odoo 19.
