Frequently Asked Questions
Is Cauri ready for Greece's 2026 B2B e-invoicing mandate?
Yes. We keep your invoices PEPPOL-ready and myDATA-aware in EN 16931 format, so you can prepare for the mandate as it phases in — large companies since March 2, 2026 and other businesses from October 1, 2026 (timeline subject to change). Please confirm the latest AADE requirements and your own obligations.
What is myDATA and how does Cauri relate to it?
myDATA is AADE's national platform for transmitting invoice and accounting data to the Greek tax authority; under the B2B mandate invoices are validated and assigned a unique identifier before transmission. Cauri produces standards-based, myDATA-aware structured invoices; depending on your setup, submission to AADE may go through a certified provider or your accounting software. Please confirm your reporting obligations.
How does AFM / VAT validation work?
We run Greek VAT (AFM) format checks and EU VIES pre-checks, using the EL prefix (EL + 9 digits), to flag issues before you send. Please confirm official AADE records for final accuracy.
Can I invoice clients in other EU countries?
Yes! Through PEPPOL, you can send e-invoices to 32 European countries, including all EU members. Cross-border compliance is handled automatically.
