American Express is both the card network and the issuer for most of its cards, which can make the dispute process faster and easier in many cases. However, it also means there’s no arbitration process by which merchants can appeal the bank’s decision and have it judged by a neutral party.

This unique dual role creates a fundamentally different dispute resolution environment compared to other major card networks. While Visa and Mastercard operate as intermediaries between merchants and hundreds of different issuing banks, American Express controls the entire process from authorization through dispute resolution. This integration can lead to more efficient communication, clearer decision-making authority, and faster resolution timelines, but it also means that American Express’s initial decision carries final authority with limited appeal options.

The integrated model provides American Express with comprehensive cardholder data, including detailed account history, spending patterns, communication records, and customer service interactions that other networks might not access during dispute resolution. This information depth can work in favor of merchants who maintain strong documentation and clear service delivery records, but it can also work against merchants when American Express can independently verify cardholder claims through internal data sources.

For subscription businesses targeting premium customers, understanding American Express disputes is crucial as their cardholders have significantly higher spending volumes, longer average customer lifecycles, and elevated expectations for service quality compared to users of other card networks. American Express cardholders typically represent higher-value customer segments with greater lifetime value potential, making dispute resolution decisions more strategically complex since merchants must balance immediate dispute costs against long-term relationship value and brand reputation considerations.

The premium positioning of American Express also influences dispute resolution expectations, with cardholders often anticipating higher levels of customer service responsiveness, more personalized dispute handling, and more generous resolution terms when problems occur. This creates both challenges and opportunities for subscription businesses that can demonstrate exceptional service quality and customer relationship management.
