Onboarding at marketplace scale is hard.
Onboarding backlogs
At scale, manual document review creates days-long queues. Legitimate sellers go live late; the more you grow, the worse the backlog gets.
Synthetic identity fraud
Fraudsters submit doctored or synthetic documents. Under pressure to clear the review queue quickly, manual reviewers miss mismatched registration numbers or altered details.
Compliance documentation
Regulators require documented evidence of each onboarding decision, especially for marketplace sellers who are effectively acting as merchants of record.
Automated verification with risk-tiered review.
Cogneris extracts and cross-checks seller documents automatically — company registration, bank letters, ID — and scores each application for fraud risk. Low-risk sellers go live without human review. High-risk applications get flagged with pre-extracted evidence, not a blank form.
- Automated cross-document checks — business registration number extracted from one doc is matched against the company name on another. Mismatches flag immediately.
- Risk-tiered routing — high-confidence, clean applications auto-approve with a full evidence trail. Edge cases and fraud flags route to human review with context.
- Altered document detection — document forgery scoring catches modified PDFs, pixel-level tampering, and font inconsistencies that human reviewers routinely miss.
- Complete audit evidence per application — every document decision logged with extracted fields, confidence scores, and check results — ready for regulatory requests.
Onboard sellers in minutes.
Marketplace seller onboarding has two failure modes, and they're opposite. Manual review is slow, rejecting good sellers and damaging fill rate. Automated review is fast but lets fraudulent sellers in, generating chargebacks and platform trust damage. Cogneris's marketplace configuration solves for both — risk-tiered automation that auto-approves safe sellers in under two minutes and routes high-risk applications to human review with pre-populated context.
Business document verification
EIN / W-9 verification, business registration, articles of incorporation, bank-account ownership letters — extracted and cross-referenced against trusted data sources.
Risk-tiered routing
Configurable rules engine: low-risk sellers auto-approved, mid-risk flagged for light review, high-risk routed to manual SIU-style investigation.
Fingerprint integration
Device-fingerprint and behavioral signals from Fingerprint flow directly into the seller-risk score. Suspicious patterns block onboarding before docs are even reviewed.
Buyer-side KYC, too
Same platform handles buyer verification flows for marketplaces with regulated transactions (firearms, regulated substances, age-restricted goods).

The document types behind seller onboarding, payouts, and dispute resolution.
Marketplaces verify sellers, route payouts based on tax forms and bank info, and adjudicate disputes that reference contracts and invoices. Cogneris extracts each input into structured fields your platform can act on.
