Unverified sellers can list counterfeit goods, create disputes, and erode buyer confidence. Multi-accounting and account takeover let fraudsters operate unchecked. Age-restricted goods need verification at checkout. And manual review backlogs slow onboarding, killing conversion for legitimate sellers.

Qoobiss provides automated KYC and KYB checks that verify sellers in seconds. ONTRACE handles identity and age verification, OMNICHECK delivers continuous AML screening, and ORIGIN orchestrates risk-based onboarding rules by market, category, or risk tier. Every action creates an audit trail for DAC7 compliance and dispute resolution.

Merchant Verification for Marketplaces & Digital Platforms

Marketplaces and digital platforms use Qoobiss to verify sellers and buyers. With automated KYC and KYB checks, identities are quickly verified. Our platform also supports AML checks and will support any age-restricted purchases. Using the Qoobiss product portfolio can help reduce multi-accounting and account takeover, all without hurting conversion. The merchant verification for marketplaces works by collecting documents to prove identity, checking all government databases, and using biometrics for secure onboarding.


Verify sellers to build marketplace trust

To establish marketplace trust, certain risks should be addressed. The prevention of unverified sellers is a focal point. Any seller that has not been verified may offer counterfeit goods and cause disputes among purchasers. To maintain the fast-paced environment of marketplaces, it is important to have a fast onboarding process. With Qoobiss, digital onboarding can be completed in seconds, providing complete seller verification. To ensure compliance and enhance trust with partners and sellers, all marketplaces and digital platforms require consistent evidence and audit trails. With the Qoobiss product portfolio, automatic audit trails are created when any action is taken to ensure audit-readiness.


What marketplaces need to solve

Online marketplaces can solve many issues with the Qoobiss product portfolio. Identity verification for marketplaces can be completed quickly to ensure sellers are legitimate. Here are some of the things that can be solved with our platform.

  • Sellers are verified before they list or receive payments

  • Repeat fraudsters and multi-accounting prevention

  • Limit high-risk behavior and use account takeover prevention (ATO)

  • Perform age checks to support the sale of age-restricted goods

  • Maintain AML and KYC compliance

  • ID coverage is needed to ensure security, and a localized user experience provides a native feel for regions


How the lifecycle works across the Qoobiss portfolio

Onboard → Verify → Screen → Monitor → Decide → Report

Across the Qoobiss product portfolio, the lifecycle is a multi-step process with modules used to complete actions to prevent fraud and money laundering. Starting with the onboarding phase, ORIGIN will orchestrate the workflows and rules. The identity of merchants will be verified through a KYC process using ONTRACE. This verified all IDs using documents, selfies, and liveness checks. In some locations, age verification for marketplaces is required, and this is solved with the platform. 

To ensure compliance, OMNICHECK works to monitor all activity and transactions. AML screening for marketplaces is performed, offering sanctions/PEP screening to prevent financial crimes. Qoobiss is an end-to-end platform, so there is KYT/Transaction monitoring offered as well. Once onboarded, sellers will undergo continuous monitoring to identify high-risk behaviors or fraudulent activity.
