Greece E-Invoicing Solution:
Get Ready with Melasoft SAP Add-On
Greece is digitizing its tax system with mandatory e-invoicing and real time VAT reporting via the myDATA platform. E-invoices must be submitted in a predefined XML format, enabling the tax authority (AADE) to prefill VAT returns and improve transparency.
Greece has received EU approval to mandate B2B e-invoicing from July 2025, with implementation likely in 2026.
With our e-compliance experience in 30+ countries, Melasoft SAP Add-On offers a simple, reliable, and fully compliant solution tailored to your company’s needs.
E-Invoicing Regulation:
Who Oversees Compliance?
The Independent Authority for Public Revenue (AADE) governs e-invoicing in Greece. It operates the myDATA (My Digital Accounting and Tax Application) platform the central system for reporting sales, purchases, and ledger data.
The e-invoicing regime supports the shift to real-time tax monitoring, reducing VAT fraud and administrative burdens.
