eInvoice Link: invoices leave your software, and the MARK number comes back.
eInvoice Link is our own platform for Greek e-invoicing. It takes the invoices from Odoo, your eshop or other business software, checks them, sends them to a licensed provider and brings back the MARK number and QR code that myDATA, the Greek tax authority's platform, gives every invoice. If the connection drops, nothing is lost.

BETWEEN YOUR SOFTWARE AND THE PROVIDER
Your software doesn't talk to the provider directly. It talks to eInvoice Link, which checks every invoice, keeps the queue and waits until the MARK number is back.

WHAT EINVOICE LINK DOES
Checks before anything leaves
VAT numbers, VAT, totals and document type, before the invoice reaches the provider. If something doesn't add up, it tells you in plain words.
Nothing gets lost
Every invoice takes its place in the queue. If the connection drops, it waits and goes out again on its own, never twice.
MARK and QR back
The MARK number and QR code come back to your software and print on the invoice, without anyone doing anything.
A console for every invoice
You see what has gone, what is waiting and why. Anything that didn't go through, you send again with one click.
A module for Odoo
In Odoo the connection is an add-on: you issue the invoice as always, and the rest happens on its own.
Many companies, one platform
Each company has its own keys and its own provider. It suits groups with several companies and accounting firms with many clients.
WHICH SOFTWARE IT WORKS WITH
Odoo
With its own module, inside Odoo, for invoices, credit notes and every document type.
WooCommerce and other eshops
An invoice from every order, with a VAT-number check when the buyer is a business.
Your group's ERP or other software
If your software has an API or a database we can read, we connect it without changing it.
CHANGE PROVIDER, NOT SOFTWARE
Your software talks to eInvoice Link, not to the provider. If you ever want a different provider, one setting changes in the platform, and your software stays as it is.
For every case, from cancelling an invoice to a broken connection, there are written procedures, twenty in all. So your team knows what to do, and doesn't have to wait for us.
QUESTIONS
Is eInvoice Link an e-invoicing provider?
No. Only companies licensed by AADE, the Greek tax authority, are providers. eInvoice Link connects your software to a licensed provider and makes sure every invoice arrives and the MARK number comes back.
Do we have to change our software?
No. You keep the software you have, and we connect it to eInvoice Link. In Odoo the connection is an add-on.
What happens if the connection to the provider drops?
The invoice waits its turn and goes out again as soon as the connection is back, never twice. In the console you see what is waiting and why. See it in how an invoice travels.
Can we change provider later?
Yes. One setting changes in eInvoice Link, and your software doesn't notice.
How much does it cost?
It depends on your software and your documents. Once we know them, we write you a fixed price for the connection. The provider's subscription you agree directly with the provider.
