The evidence that actually wins a dispute, and the deadlines you cannot miss

Fighting a chargeback is a documentation exercise judged by someone processing a queue. What wins is specific evidence tied to the specific claim. What loses is an explanation of how unfair it is, however true that is.

First: is it worth fighting?

Honestly, sometimes not. Weigh the amount against the time, and against the fact that many disputes are lost regardless of merit. A $9 subscription dispute is rarely worth an hour. A $300 custom order is.

Where your rate is climbing, fight more of them — the rate itself has consequences beyond the individual amounts.

The deadlines are short and they are real

Typically 7 to 21 days from notification depending on the platform and processor. They are not extended, and a late response is an automatic loss. Diary it the day the notification arrives.

What actually helps

Match the evidence to the reason code — the stated reason for the dispute tells you what you have to rebut.

"I didn't authorise this." You want anything tying the account to the cardholder: signup records, IP and device consistency across sessions, login history, and a purchase pattern showing an established relationship rather than a single unfamiliar charge.

"Not as described." The listing or preview as it appeared, proof of what was delivered, and delivery timestamps. If they messaged you afterwards about anything at all, that message proves receipt.

"I never received it." Access and download logs. For digital goods this is usually the most winnable category, because the platform's own records show delivery.

"I cancelled and was still charged." Your subscription records and cancellation history. If they did not cancel, the record shows it.

What gets ignored

• Emotional appeals, however justified
• Long narratives without documents
• Screenshots with no timestamps or context
• Arguments about the cardholder's character
• Anything that does not address the specific reason code

Be brief and factual. State what was purchased, when, what was delivered, when, and attach the records. The reviewer is looking for a match between claim and evidence, not for the more sympathetic party.

What to keep, always

You cannot assemble evidence you never had. Keep transaction IDs and dates, access and delivery records, message history, and your terms as they were at the time of purchase. Most of this the platform holds — the point is knowing where to pull it from quickly when a clock is running.

The cheaper move, usually

When someone is unhappy and reachable, refunding is often cheaper than a dispute. A refund costs the amount. A dispute costs the amount, plus the fee, plus the effect on your rate, plus the time. That maths favours the refund more often than pride suggests.

And log everything, win or lose. Disputes are a real reduction in income, they are deductible, and creators who never record them overstate their earnings all year.
