Q: What accounting software is popular in Greece?

The most popular accounting platforms in Greece include Xero, QuickBooks, NetSuite, Microsoft Dynamics 365 Business Central, Sage Intacct. Greek accounting software is a two-horse race between the Epsilon Net group (Pylon, Galaxy, Epsilon Smart) and EntersoftOne (formed by the 2024 Entersoft + SoftOne merger). The mandatory myDATA platform from AADE drove mass migration from legacy and paper-based processes.

Greece accounting compliance requirements

Greece requires nearly all businesses to transmit invoice, expense and payroll data electronically to myDATA, the digital bookkeeping platform run by the tax authority AADE, and from 2026 that reporting layer is being upgraded into a mandatory structured B2B e-invoicing regime rolled out by company size.

myDATA

Businesses transmit sales, expense and payroll data electronically to AADE, which uses it to pre-fill VAT and income tax returns.

AADE (Independent Authority for Public Revenue)

Mandatory B2B e-invoicing rollout

Large businesses must comply from 2 March 2026 and virtually all remaining resident businesses from 12 October 2026, transmitting structured invoices to AADE in real time.
