Seller verification in seconds
Multi-accounting and account takeover prevention
Verified seller data for DAC7 due diligence
WHAT IT SOLVES
Unverified sellers bring counterfeits, scams and disputes, and fraudsters come back under new accounts once they’re banned. Age-restricted goods need checks at checkout, and EU platforms have to collect and verify seller details for DAC7. Manual reviews can’t keep up without slowing seller onboarding.
Qoobiss handles it in one flow. ONTRACE verifies seller identity and age with document, face and liveness checks, ORIGIN runs KYB and UBO checks for business sellers, and OMNICHECK screens everyone against sanctions and PEP lists. Every check is logged, so you have evidence for DAC7, disputes and regulators.

Merchant Verification for Marketplaces and Digital Platforms
Qoobiss provides merchant verification for marketplaces, sharing-economy platforms and digital platforms. It verifies sellers and buyers with identity verification, KYB and UBO checks, AML screening and age checks, and collects the verified seller data EU platforms need for DAC7. Seller onboarding stays fast, so genuine sellers go live in minutes while fraudsters are stopped at the door.
Verify Sellers to Build Marketplace Trust
Buyers trust a marketplace when they trust its sellers. Unverified sellers bring counterfeits, scams and disputes, and banned fraudsters return under new accounts. Automated KYC verification checks every seller before their first listing, and biometric matching links new sign-ups to accounts you’ve already banned, so the same person can’t come back. Every check is logged automatically, so you have evidence for partners, disputes and regulators.

DAC7 Seller Due Diligence
Under the EU’s DAC7 directive, digital platforms that facilitate sales of goods, services or rentals must collect and verify information about their sellers, including identity, address, date of birth and tax identification number, and report sellers’ income to tax authorities every year. Qoobiss provides the verification side: identity confirmed against the seller’s document, business details checked against registries, and every record stored with an audit trail. Your platform then has verified data ready for its DAC7 reporting.
Marketplace Fraud Prevention
Most marketplace fraud depends on fake or repeat identities: sellers who disappear after taking payment, buyers who file false chargebacks, and account takeover of trusted seller profiles. Verification closes those gaps by tying every account to one real person or business. See how Qoobiss handles fraud prevention and chargeback fraud.
