What is Chargeback Fraud?
Chargeback fraud—a.k.a. “friendly fraud”—is when a cardholder reverses a legitimate purchase to
retrieve funds after receiving the merchandise or service. Driven by buyer’s remorse or by knowing abuse of
dispute timelines and shared accounts, chargeback fraud is zero-sum: the merchant bears the loss, fees, and
workflow interruptions.
Perpetrators take advantage of frictionless ecommerce, liberal refund policies, and spotty evidence packages.
One successful representment is a lesson that your store is vulnerable. Social groups then share their
playbooks.
Countermeasures: make descriptors specific, and implement proof of delivery and use logs for digital
goods; reconcile billing and device history; and compile evidence‑ready case files with timestamps, IP
addresses, device IDs, and history of prior activity. Track reason codes by BIN, SKU, and segment; and tailor
your policies to where the abuse is hottest. Adapt transaction limits and step‑ups to risky shopping carts and
payout amendments. For new or high‑exposure customers, bind their identity with robust identity verification, and layer your checkout controls to disallow serial abusers on return—see payment fraud prevention. Whether malicious or not, a dispute is information. Treat it as a data point, not just a loss.
