Key Features to Look for in an Invoice App for Greece
Choosing an invoice app for Greece requires strict adherence to local tax regulations, primarily the myDATA platform. A compliant app must support the mandatory transmission of all B2B and B2G accounting data to the myDATA platform, which has been obligatory since 2020 for all companies under Greek accounting standards. For B2B transactions, mandatory e-invoicing is being phased in, starting March 2, 2026, for large companies and October 1, 2026, for others. Therefore, the app should be capable of generating invoices in the required structured formats.
Specifically, look for:
- Compliance with Greek Tax Regulations: The app must facilitate real-time reporting of transaction data to the Independent Authority for Public Revenue (AADE) via the myDATA platform. This includes generating a unique invoice identifier (MARK) upon validation. Non-compliance can result in penalties ranging from €100 to €20,000 annually.
- Support for UBL Invoice Formats: For B2G transactions, the app should support the Peppol BIS 3.0 format, which is based on UBL and the EN 16931 standard with a Greek CIUS. For B2B clearance, UBL 2.1 GR is specified. UBL (Universal Business Language) is an XML-based standard that ensures data consistency and faster processing.
- Integration with Greek Banking Systems: Seamless integration with major Greek banks (e.g., Alpha Bank, Eurobank, National Bank of Greece, Piraeus Bank) can automate payment reconciliation, eliminating manual processing and updating accounts immediately. Some banks also offer e-invoicing functionalities through their e-banking platforms.
