Automate seller KYB verification and eliminate six-figure DAC7 penalties.

Under EU Directive 2021/514 (DAC7), platform operators must authoritatively collect, verify, and report seller tax identification numbers, business registers, and active trading status. Reporting unverified or invalid seller data triggers statutory platform fines up to €900,000 and mandatory payout freezes.

The Business Risk

The DAC7 Seller Reporting and Due Diligence Burden

Marketplaces onboarding thousands of freelancers, service providers, or merchants face strict annual reporting mandates. Sellers frequently provide unregistered trade names, dormant company numbers, or mistyped tax identifiers. Platforms relying on unverified onboarding forms submit flawed DAC7 XML filings that national tax authorities immediately reject.

  • Platforms collect seller-declared tax numbers without authoritative verification against national registries.
  • Tax authorities audit annual DAC7 data dumps and find hundreds of mismatched legal names and cancelled tax identifiers.
  • Platforms face severe statutory penalties, forced account suspensions, and public regulatory enforcement actions.
Financial Impact of Failure€100,000–€900,000Statutory non-compliance fines across EU member states for submitting invalid or unverified seller tax records under DAC7.
