Integration with AADE myDATA
mytameio is designed for the electronic books obligations of Greek businesses. Here is exactly what is available today and what is coming soon.
What is myDATA
myDATA ("my Digital Accounting and Tax Application") is the electronic books platform of the Independent Authority for Public Revenue (AADE). Businesses transmit the details of their documents to it; for every accepted document AADE assigns a unique registration number (MARK).
What mytameio does today
- Maps invoices to the myDATA document types (e.g. Sales Invoice, Credit Invoice)
- Official AADE code lists: VAT categories, VAT exemption reasons, income classifications, payment methods
- Validates every document against the official XSD schema before transmission
- Transmits and receives MARK, UID and QR code in the myDATA test environment (sandbox)
- Stores each business's AADE credentials encrypted
The journey of an invoice
-
Issue
The invoice is issued with a document type, VAT category and income classification.
-
Validate
The data is checked against the official myDATA XSD schema.
-
Transmit
The document is transmitted to AADE with the business's own credentials.
-
MARK and QR
MARK, UID and QR code are stored and shown on the invoice.
AADE modules
Both modules are optional; all other mytameio features (customers, offers, contracts, invoices, payments) are available to everyone.
Coming soon
Retail — sales receipts (POS)
Retail Sales Receipts (Απόδειξη Λιανικής Πώλησης) issued through a certified provider (ΥΠΑΗΕΣ) and transmitted to myDATA.
E-invoicing through a certified provider
For e-invoicing and retail receipts, mytameio will work with a certified electronic invoicing service provider (ΥΠΑΗΕΣ). The provider issues and transmits the documents according to the AADE specifications.
During the free trial
During the 7-day free trial the AADE integration runs exclusively in the myDATA test environment (sandbox): you can try the whole flow without transmitting any real document.
Questions about AADE and myDATA
Questions about mytameio, the AADE modules or the plans? Write to us and we will reply as soon as possible.
Can I transmit real documents to myDATA today?
Not yet. The integration currently runs in the AADE test environment (sandbox). Transmission to the production environment will be enabled with the Wholesale module, which is coming soon.
What is the MARK?
The MARK (Μοναδικός Αριθμός Καταχώρισης, unique registration number) is assigned by AADE to every document successfully transmitted to myDATA. mytameio stores it with the invoice.
What are the UID and the QR code?
The UID is the unique identifier of the document, calculated from its key details (issuer VAT number, date, series, number, etc.). The QR code links to the document's record in myDATA and is printed on the invoice.
Do I need an e-invoicing provider?
That depends on your business's obligations and how you choose to issue documents; please ask your accountant. For e-invoicing and retail receipts mytameio will work with a certified provider (ΥΠΑΗΕΣ).
Where are my AADE credentials stored?
Your AADE credentials (myDATA user name and API key) are stored encrypted and used only for your own business's integration.
