Card Transaction DisputesChargeback

A chargeback is a transaction reversal initiated by a cardholder through their issuing bank. The bank pulls funds from the merchant’s account while the dispute is investigated. Chargebacks carry fees regardless of outcome and represent one of the primary fraud and dispute risks in card acceptance. According to the Federal Reserve’s payment system oversight framework, dispute management is one of the core risk controls acquiring banks must enforce on behalf of card networks.

There are three common reasons a dispute gets filed: the customer claims they never received the goods or services, they claim the transaction was fraudulent, or they claim the charge was unauthorized. In each case, the burden falls on the merchant to prove otherwise — within a limited response window.

Here is the flow of a typical dispute:

The evidence required varies by reason code. For “item not received” disputes, delivery confirmation and tracking data are primary. For “unauthorized transaction” claims, AVS match, CVV match, and prior purchase history strengthen the merchant’s position. For service disputes, signed agreements, communication records, and proof of service delivery are most relevant.

The cost of losing is not just the transaction amount. Each dispute carries a fee of $15–$50 from the processor — charged regardless of whether the merchant wins or loses. The CFPB’s guidance on cardholder dispute rights outlines what cardholders are entitled to in the process — understanding their perspective is the fastest path to building a winning response.

Card networks monitor the ratio of disputes to total monthly transactions. Visa’s standard threshold is 1% — one dispute per 100 transactions. Mastercard uses a similar standard. Merchants who consistently exceed this threshold are placed in monitoring programs that carry additional fees and reporting requirements. Sustained high ratios can result in account termination and placement on the MATCH list.

Merchants in flagged verticals need specialized underwriting — see high-risk payment processing for how approval and pricing work outside the standard rails.

Card-present chip and tap transactions carry significantly lower dispute liability than card-not-present transactions — the physical card being present limits unauthorized transaction claims. For online and phone orders, AVS and CVV verification reduce fraud exposure. Clear refund policies, recognizable billing descriptors, and prompt customer service resolve most issues before they escalate to a formal dispute.

Recurring billing merchants face above-average exposure because customers who forget to cancel often file disputes rather than contacting the merchant directly. Proper stored credential authorization, clear cancellation communication, and advance billing notifications all reduce this risk significantly.
