What they cost, how to fight them, and how to avoid most of them
A chargeback is a forced reversal initiated by the cardholder's bank, and it costs more than the sale. Beyond losing the revenue and the goods, merchants absorb a per-dispute fee and risk placement in a monitoring program if the ratio climbs. Friendly fraud — where a legitimate customer disputes a purchase they actually made — now accounts for a large share of small-business disputes, and it is the category most preventable through operations rather than technology. This guide covers the lifecycle, the evidence that wins, and the habits that keep ratios low.
A cardholder contacts their issuer, the issuer provisionally credits them and debits your account, and you receive a notice with a reason code and a response deadline. If you contest it, you submit evidence — representment — and the issuer decides. Deadlines are strict and missing one forfeits the case automatically.
Generic responses lose. Match your evidence to the specific reason code cited.
Each dispute typically carries a fee regardless of outcome, and the merchandise is usually unrecoverable. Sustained ratios above roughly one percent of transactions can trigger network monitoring programs, which bring additional fees and, in severe cases, account termination.
Most disputes are avoidable. Use a clear, recognizable billing descriptor so customers identify the charge on their statement, answer refund requests quickly, capture card-present transactions with chip or tap rather than keying, and post your return policy at the point of sale and on receipts.
In-person chip and contactless transactions shift most counterfeit fraud liability to the issuer. Keyed, online, and phone orders leave the liability with you, which is why card-not-present businesses need address verification, CVV checks, and delivery documentation as standard practice.
Response windows are typically measured in days, not weeks, and vary by reason code. Treat every notice as urgent.
Refunding after a dispute is filed can result in a double loss. Refund before a dispute starts, or contest it — not both.
Roughly one percent of transactions is the common threshold for network monitoring programs, though thresholds vary.
It shifts counterfeit fraud liability to the issuer, but it does not prevent disputes based on service quality, duplicates, or non-recognition.
