Card issuers are often able to detect that a transaction is fraudulent before it is disputed, and when this happens, they will send us a notification. These notifications are commonly called TC40s (Visa) or SAFE reports (MasterCard). On average ~60% of early fraud warnings end up being disputed, and most disputes have an early fraud warning (though there’s a wide range depending on your business). If you refund these charges before they become disputes, you can avoid the dispute entirely. It doesn't solve all dispute problems but it can be pretty effective. I’m happy to take a look at your account to calculate what percent of disputes have an early fraud warning.
