TL;DR: Friendly fraud chargebacks occur when legitimate cardholders use the dispute process to reclaim funds fraudulently, and Signifyd says merchants are now seeing more gen AI-aided refund abuse, with an 8% year-over-year increase in such attempts early last year. The control problem is no longer just fraud detection, but evidence quality, post-purchase governance, and abuse-resistant customer journeys.
NHIMG editorial — based on content published by Signifyd: Prevent Friendly Fraud Chargebacks: 8 Best Practices for Merchants
By the numbers:
- Signifyd saw an 8% year-over-year increase in such attempts early last year, for instance.
- Customers who receive an instant refund upon scanning their return package for its return trip are 23% more likely to make an additional purchase from that merchant within 30 days, according to Signifyd data.
- On average, merchants that partner with Signifyd see a 50% higher chargeback win rate.
Questions worth separating out
Q: What breaks when merchants rely only on CVV and two-factor authentication to stop friendly fraud?
A: Those controls stop stolen-card fraud, but they do not help when the cardholder is the person abusing the dispute process.
Q: Why do legitimate cardholders create a harder fraud problem than stolen cards?
A: Because the transaction itself is valid, merchants lose the easy indicators that usually trigger fraud controls.
Q: How do you know if chargeback prevention is actually working?
A: Look for fewer preventable disputes, higher representment win rates, shorter evidence-collection times, and lower rates of false INR and SNAD claims.
Practitioner guidance
- Strengthen front-end abuse scoring Combine identity signals, shopping pattern analysis, prior chargeback history, and address verification before fulfilment so suspicious orders are reviewed early rather than disputed later.
- Harden post-purchase evidence capture Store order confirmations, shipment tracking, product descriptions, customer emails, and delivery proof in a dispute-ready record so representment is fast and complete.
- Make billing and fulfilment less ambiguous Use recognisable billing descriptors, accurate product naming, and proactive shipping updates to reduce false claims rooted in confusion or buyer’s remorse.

Friendly fraud is an identity problem disguised as a payments problem: the person who initiates the dispute is often the same person who completed the transaction. That makes the usual fraud lens incomplete, because the merchant is not defending against stolen credentials but against abuse of a trusted identity and a trusted process. For IAM and fraud teams, the real control question is whether the organisation can distinguish legitimate cardholder intent from opportunistic dispute behaviour without degrading the customer journey.
A question worth separating out:
Q: Who is accountable when friendly fraud chargebacks rise across ecommerce channels?
A: Accountability usually sits across fraud, payments, customer operations, and support, because the failure spans transaction controls and post-purchase experience. The merchant also carries the burden of proof in the dispute process, so leaders must govern evidence retention, billing presentation, refund policies, and response workflows as one programme.
