E-Invoicing Provider

An E-Invoicing Provider is an AADE-certified software company that undertakes the issuance, authentication, and automatic transmission of your invoices to the AADE's myDATA system

What is an E-Invoicing Provider?

Under current legislation, an "electronic sales document issuance service provider" is an AADE-certified software company responsible for issuing, authenticating, and automatically transmitting your invoices to the AADE's myDATA system.

Under the new system, businesses transmit their transaction data to a certified Provider. The provider issues the electronic invoice and simultaneously sends it to the issuer, the recipient, and AADE's myDATA in real time.

The authenticity of each invoice can be verified by anyone through the provider's website, using the QR code that is mandatory on every electronic invoice.

Is it mandatory to have an E-Invoicing Provider?

Yes it is. E-Invoicing through a certified provider is mandatory for business-to-business (B2B) transactions in Greece. The measure is being rolled out gradually based on turnover, and the obligation has already begun for larger businesses.

The rollout is divided into two phases:

•

Businesses with turnover above €1,000,000 (based on the 2023 tax return): Use of a provider is already mandatory (since early February 2026).

•

All other businesses (turnover below €1 million): Mandatory issuance through a provider begins on 1 October 2026, with a transitional adaptation period until the end of the year.

Business Benefits

Tax incentives for early adoption

Businesses that choose to implement electronic invoicing two months ahead of the applicable deadline enjoy full depreciation of hardware and software expenses in the year of purchase, increased by 100%, as well as a 100% uplift on expenses for the production, transmission, and electronic archiving of electronic invoices for the first 12 months of issuance.

Reduced record-keeping period

Through a certified provider, businesses can reduce the required retention period for tax records and books subject to AADE audit by two (2) years.

Savings on cash register costs

Through a provider, businesses can issue and transmit certified electronic documents to their customers and to the myDATA platform without the use of a fiscal device or cash register, freeing them entirely from daily "Z" reports, paper receipt filing, and regular roll replacements.

Automatic archiving & legal coverage

The provider is legally obligated to archive clients' documents for 5 years and transmit summaries to AADE. Documents are issued and transmitted automatically and with complete security, in full compliance with applicable legislation.

Time & operational cost savings

No printing or physical filing is required, saving the business both time and money.
