Sovos Receives Y.PA.H.E.S. Accreditation from AADE, Becoming a Direct Certified E-Invoicing Provider in Greece

ATLANTA, GA - October 05, 2026 - Sovos, the agentic tax compliance company, today announced that it has received Y.PA.H.E.S. accreditation from Greece's Independent Authority for Public Revenue (AADE), making it one of a select group of foreign-domiciled service providers certified to deliver e-invoicing compliance directly in the Greek market. With this accreditation, Sovos is authorized to support Greece's Continuous Transaction Control (CTC) mandate: B2B e-invoicing and myDATA eAudit as one unified compliance process

Greece is implementing one of the most comprehensive digital tax transformation programs in Europe, and the timing of this accreditation is significant. For large businesses (with gross revenue exceeding €1 million in fiscal year 2023), mandatory implementation began in March 2026, with a transition period running during parts of 2026 during which businesses can gradually adapt while continuing to use existing ERP or accounting software. For all other businesses, mandatory implementation begins 1 October 2026, with a transition period through 31 December 2026.

"Becoming a direct certified provider is not just a regulatory milestone - it is a demonstration of our ability to engage with tax authorities at the highest level, deliver fully compliant solutions, and support our customers in Greece,", said Christiaan Van Der Valk, Chief Regulatory & Industry Affairs Officer, Sovos. "Sovos continues to invest in the European market and is the standard-bearer for businesses needing to ensure tax compliance across multiple jurisdictions."

Greece is not new territory for Sovos. Having supported customers operating in Greece for nearly 20 years through our Post Audit Invoice Issuance, eArchiving, myDATA eAudit and eTransport solutions, the company has built a track record of success across Greece's digital tax mandates, giving it deep familiarity with the regulatory framework, the myDATA platform, and the compliance needs of businesses operating in the country. That experience now underpins Sovos' position as a direct certified provider, equipped to serve both existing customers and Greek businesses seeking a trusted compliance partner ahead of upcoming mandate deadlines.
