A chargeback is a transaction reversal initiated by a cardholder through their bank, disputing a charge on their credit or debit card statement. The merchant loses the revenue, is charged a chargeback fee (typically $20-100 per incident), and must respond with evidence or accept the reversal. A chargeback ratio above 1% triggers card-network penalties.
Chargebacks were created as a consumer protection mechanism — if a cardholder's card is fraudulently used, or a merchant fails to deliver goods/services, the cardholder can dispute the charge with their bank. The issuing bank initiates a reversal, and the merchant must either accept it or submit a 'representment' (dispute response with documentation). There are three main chargeback categories: (1) Fraud — unauthorized use of the card (true fraud). (2) Friendly fraud — cardholder disputes a legitimate purchase they forgot about or regret. Friendly fraud is estimated to account for 60-80% of all chargebacks according to Federal Reserve payment studies. (3) Service/product dispute — goods not received, not as described, or service not rendered. Chargebacks are expensive beyond the transaction loss: chargeback fees typically run $20-100 per dispute, regardless of outcome. Win or lose, the fee is charged when the chargeback is filed. The time cost of representment (gathering evidence, submitting responses) adds more. And if the chargeback ratio — chargebacks as a percentage of monthly transactions — exceeds card-network thresholds, consequences are severe: Visa's threshold is 0.9% (dispute ratio) and 0.65% (fraud ratio); Mastercard's is 1.5% (dispute ratio). Exceeding these triggers the excessive chargeback monitoring program, imposing escalating monthly fines until remediation. Sustained high chargebacks lead to processor termination and placement on the MATCH list (Member Alert to Control High-Risk Merchants) — effectively a permanent ban from card acceptance. For MCA underwriting: payment processors flag high chargeback merchants. An MCA underwriter reviewing processing statements will look at the chargeback ratio as a risk signal. High chargebacks indicate customer satisfaction problems, delivery disputes, or fraud exposure — all credit risks.
Typically 7-14 days from the date the processor notifies you of the chargeback, depending on the card network and processor. Deadlines are strict — missing the response window forfeits the dispute automatically. Set up chargeback alert services (like Verifi or Ethoca) to receive same-day notification and preserve the response window.
Compelling evidence varies by reason code: for 'item not received' disputes, show proof of delivery (tracking, signature confirmation, GPS proof). For 'unauthorized transaction,' show customer login, IP/device matching, prior order history. For 'not as described,' show product photos, description matching, and any customer service exchange. For subscriptions, show the signed authorization, clear cancellation policy disclosure, and reminder emails sent.
MATCH (Member Alert to Control High-Risk Merchants) is Mastercard's industry blacklist — a database of merchants whose processing agreements were terminated for cause (excessive chargebacks, fraud, illegal activity). Being placed on MATCH makes it extremely difficult to establish new merchant services. Processors check MATCH before onboarding new merchants. It is not the same as a credit reporting issue, but the practical consequence is similar.
