Most chargeback fights are decided before the dispute ever arrives. The merchants who win keep clean records, respond fast, and send the issuer exactly what it needs to rule in their favor. The merchants who lose send everything they have and hope.
This guide covers the response side: what to do once a dispute lands. If you want to stop disputes from arriving in the first place, start with our guide to chargeback prevention. The two work together, and neither replaces the other.
Read the Reason Code Before Anything Else
Every chargeback carries a reason code assigned by the card network. That code tells you what the cardholder claimed: the item never arrived, the charge was fraudulent, the product was not as described, the subscription was canceled.
The code determines which evidence counts. A signed delivery confirmation wins an item-not-received dispute and does almost nothing in a not-as-described dispute. Sending every document you have is weaker than sending the three documents that answer the specific claim, because the person reviewing your response has limited time and no obligation to dig.
So before you gather anything, read the code and write down the one question your evidence has to answer.
Decide Whether This Chargeback Is Worth Fighting
Not every dispute deserves a response. A simple frame:
- Fight when you have direct evidence against the claim: proof of delivery, proof the cardholder authorized the charge, proof they used the product after disputing it.
- Concede when you do not. A weak response costs you time and wins nothing.
- Refund proactively when a customer contacts you before disputing. A refund costs the sale; a chargeback costs the sale plus fees, and it counts against your ratio whether you win or lose.
That last point matters more for high-risk merchants than anyone else. Winning the representment recovers the money, but the dispute itself may still count toward network monitoring thresholds. Fight the winnable cases, and treat the rest as a prevention problem.
Assemble Compelling Evidence by Dispute Type
Match your evidence to the claim. The pairings below cover the most common disputes.
"I never received it." Tracking number, carrier delivery confirmation, signature on delivery where you have it, and the shipping address matched against the billing address on the order.
"I didn't make this charge." AVS and CVV match results from the transaction, the customer's order history with you, IP address or device data tying the order to the cardholder, and any communication from the customer about the order after it was placed.
"It wasn't as described." The product page as it appeared at purchase, the description and photos the customer saw, your return policy and proof the customer accepted it at checkout, and any record that the customer never attempted a return.
"I canceled the subscription." The signup record with timestamp, the billing terms the customer agreed to, your cancellation policy, and your logs showing no cancellation request before the billing date.
If a category above exposes a record you do not currently keep, fix that today. Evidence you start collecting now wins disputes six months from now.
Write a Representment Package the Issuer Can Skim
This is where most merchants lose winnable cases. The reviewer at the issuing bank is working through a stack of disputes. Make yours the easy one.
- Lead with a summary. One paragraph: what the cardholder claimed, and the single strongest fact against it. State your conclusion first, then support it.
- Label every exhibit. "Exhibit A: Carrier delivery confirmation, signed, matching the billing address on the order." Never make the reviewer guess what a screenshot shows.
- Stay factual. No frustration, no speculation about the cardholder's motives. A dry, organized response reads as credible. An angry one reads as weak.
- Keep it short. Every page you add beyond what the reason code requires dilutes the pages that matter.
Respond Inside the Deadline, Every Time
Each dispute notice states a response deadline, and a late response is a forfeit regardless of how strong your evidence is. The deadline varies by network and processor, so treat the date printed on the notice as the only one that counts.
Build a standing process rather than improvising each time: one person owns disputes, evidence templates for each common dispute type are built in advance, and work on every new dispute starts the same day the notice arrives. Merchants who respond on day one are assembling evidence; merchants who respond at the deadline are assembling excuses.
What Winning and Losing Each Mean
Win, and the disputed funds come back to you. Lose, and you can sometimes escalate, though the cost of a further round often exceeds the transaction. Either way, the dispute happened, and your chargeback ratio is what banks and networks watch. That is why the response process in this guide and the prevention work in our chargeback prevention guide belong to the same discipline: fight the disputes you can win, and shrink the number you have to fight.

Frequently Asked Questions
Every chargeback carries a reason code assigned by the card network. It tells you what the cardholder claimed — the item never arrived, the charge was fraudulent, the product was not as described, or the subscription was canceled — and it determines which evidence counts in your response. Read it before you gather anything.
No. Fight when you hold direct evidence against the claim, such as proof of delivery or proof the cardholder authorized the charge. Concede when you do not, because a weak response costs time and wins nothing. And when a customer contacts you before disputing, refund proactively: a refund costs the sale, while a chargeback costs the sale plus fees and counts against your ratio either way.
Representment is how you fight a chargeback: you submit a response and supporting evidence to the issuing bank to show the disputed transaction was valid. A strong package leads with a one-paragraph summary, labels every exhibit, and stays strictly factual. Win, and the disputed funds come back to you.
You forfeit the dispute, no matter how strong your evidence is. Deadlines vary by network and processor, so treat the date printed on the dispute notice as the only one that counts, and start work the same day the notice arrives.
No. Winning recovers the disputed funds, but the dispute itself may still count toward the monitoring thresholds banks and card networks watch. That is why response and prevention belong to the same discipline: fight the cases you can win, and shrink the number you have to fight with the steps in our chargeback prevention guide.
High-risk is the only thing we do. We pair a high-risk merchant account with chargeback management tools that flag disputes early and help keep your ratio where the banks need it. If your current processor has put you on notice over disputes, contact us — most merchants are approved within 24 hours.
