Cost of Poor Verification Quality: Refunds, Chargebacks, and Compensation from Bad Sellers

4 verified sources

Definition

Inadequate seller vetting allows low‑quality or malicious sellers to operate, resulting in counterfeit goods, non‑delivery, and scams. Marketplaces then absorb costs through refunds, chargebacks, buyer compensation programs, and additional support interactions, as well as reputational damage that depresses future transactions.

Key Findings

  • Financial Impact: $1M–$50M+ annually for large platforms when factoring refunds, chargebacks, buyer protection payouts, and support costs related to fraudulent or non‑compliant sellers
  • Frequency: Daily
  • Root Cause: Verification focuses on minimal identity checks rather than holistic seller risk (e.g., business legitimacy, history of complaints, bank and address consistency). There is limited ongoing monitoring after initial onboarding, so sellers can degrade quality or pivot into abusive behavior without timely intervention.
