What you include in your representment document will vary, depending on the reason code given by the issuer. Fraud reason codes will usually require AVS and CVV confirmation, whereas service-based reason codes like “Service Not Rendered” will require a work order or proof of service.
Ultimiately, the representment prepared by a merchant must address the specific requirements set by the reason code and the merchant's processor. This is the best chance at disproving the any dispute.
