Industry-Specific Tactics for Amex A 01



While the general principles of Amex A 01 defense apply broadly, specific industries face unique challenges and require tailored tactics. Adapting your strategy to your business model can significantly enhance your effectiveness in fighting "Merchandise/Services Not Received " chargebacks.

For e-commerce merchants, robust proof of delivery is paramount.

Proactive communication about delivery exceptions, such as delays or alternative pickup points, can prevent many claims.



Saa S & Subscription Defense



Saa S and subscription businesses must focus on irrefutable service usage logs. These logs should detail login times, IP addresses, feature usage, and any account activity. Clear and accessible cancellation processes, along with transparent communication about billing cycles, are essential to prevent claims of non-receipt or unauthorized charges after cancellation attempts.



Travel & Hospitality Approach



In travel and hospitality, the defense hinges on booking confirmations, detailed no-show policies, and proof of attempts to contact the guest regarding their reservation. Documentation of check-in/check-out, room usage, or flight boarding passes is critical. Communication logs regarding any itinerary changes or cancellations are also vital.



High-Risk Merchant Tactics



High-risk merchants, often dealing with higher average transaction values or digital goods, need to implement enhanced fraud screening measures. Stricter delivery verification protocols, such as requiring signature confirmation for all deliveries, are crucial. Robust terms and conditions that clearly outline delivery, refund, and cancellation policies are also fundamental.
