How to Dispute a Chargeback as a Merchant
A chargeback lands on your shop. Here is what to do next, step by step, for Visa, Mastercard and American Express, from reading the reason code to hitting the deadline.
A chargeback notice arrives. The sale amount is gone from your account, and a clock has started. This page walks through what to do next. Read the reason, decide to fight or let it go, gather the right proof, and answer before the deadline. The steps below cover Visa, Mastercard and American Express, since each network runs its own process.
What disputing a chargeback means
When a cardholder's bank files a chargeback, the money leaves your account and you get a chance to answer. Visa says a merchant who cannot fix a dispute takes the loss. Your answer, called representment, is where you push the sale back through with proof it was valid. Visa says a merchant may settle a dispute by giving its acquirer more details about the sale.
You have two moves. Visa lays out two paths in its dispute life cycle. The merchant can accept the dispute, or reject it, and a rejection must come with supporting documents. To accept is to let the chargeback stand. To reject is to fight back with evidence.
Accepting is sometimes the right call. Visa says that when a dispute cannot be fixed, accepting it may save the time and cost of fighting it. When you have no proof, or the customer is clearly right, accepting is the cheaper road. If you stay silent, you lose anyway. Visa says a merchant can lose the sale amount and the goods, and also pay its own costs to respond. For a fuller look at this choice, see disputing a chargeback.
Step 1: Read the reason code and the deadline
Every chargeback comes with a reason code. It tells you what the cardholder claims: fraud, goods never received, a cancelled subscription, a refund never issued. The code decides what proof will work.
The notice also carries a deadline. Visa says the merchant's time to respond is the time on the acquirer's request, and it may vary by acquirer. So read your own acquirer's notice, not a general rule of thumb. American Express runs its own track. An American Express online account shows each dispute's details, deadlines and response options in one place. A merchant can answer American Express disputes online and upload supporting documents from a computer.
Step 2: Decide whether the dispute is worth fighting
Before you build a case, ask if one exists. You need documents that speak to the exact reason on the notice. A tracking number answers a "goods never received" claim. It does nothing for a claim that the customer cancelled.
Also weigh the cost. Fighting takes staff time, and the outcome is never sure. Compelling evidence does not force the issuer to decide that the cardholder took part in the sale. If your proof is thin, accepting may be the cheaper road. If you have strong proof matched to the reason, fight. The next section on how to fight chargeback cases goes deeper on building the case.
Step 3: Gather evidence matched to the dispute reason
This is the heart of it. Match your documents to the claim, not to a generic checklist.
Card-absent fraud, when the customer really did buy from you. Visa defines Compelling Evidence as proof from a merchant or acquirer that the cardholder took part in or benefited from the sale. Earlier payments for the same goods or service that were never disputed can serve as evidence. A merchant can answer a card-absent fraud dispute with earlier undisputed purchases that share data like device ID or IP address. Evidence that the same device and card were used in an earlier sale that was not disputed can support a merchant. Photos or emails showing that the cardholder has or uses the goods can serve as evidence. A merchant can offer evidence that a member of the cardholder's household or family made the purchase.
Goods or services not received. Proof of delivery or pickup lets you answer a dispute where the customer says the goods never came. Visa's guidelines say merchants can respond with documentation proving the cardholder or authorized person received the merchandise or services as agreed. If the delivery date has not passed yet, Visa's guidelines say merchants can respond with documentation supporting the expected delivery date.
Cancelled subscriptions. For a subscription, a merchant can show a binding contract, that the cardholder uses the service, and an earlier undisputed payment. Visa's guidelines say a merchant can respond by showing the cardholder did not cancel according to the disclosed policy. Visa's guidelines say a merchant can respond by providing proof the cardholder used services after withdrawing permission to bill.
Refund claims. Sometimes the claim is that the cardholder paid by other means. Then Visa's guidelines say a merchant can show sales records that no other form of payment was used. Visa's guidelines say merchants can respond by providing documentation to refute the cardholder's bank's evidence when the sale is valid.
Other claims. Visa's guidelines say a merchant can respond by providing specific information or documentation to refute the cardholder's claims. Visa's guidelines say a merchant can provide a letter or email from the cardholder stating they no longer dispute the transaction.
American Express asks for the same discipline. American Express tells merchants to review the entire claim and address the specific dispute reason with their documents. A reply to an Inquiry from American Express should fully address the dispute reason and every claim the Card Member made.
Step 4: Submit before the deadline
Send your response through your acquirer or processor, or through the network's own channel. A merchant can answer American Express disputes online and upload supporting documents from a computer. Attach every document, keep copies, and note the date you sent it.
Miss the deadline and the case closes against you. If a merchant does not reply to American Express in time or with the requested documents, its account is debited. To avoid a No reply or Insufficient reply Chargeback from American Express, a merchant should answer an Inquiry within 20 days. The mechanics of resubmitting the sale are covered in chargeback representment.
What happens after you respond
On Mastercard, the acquirer's response is called the second presentment. The issuer then reviews your documents and either drops the chargeback or pushes on.
On Mastercard, the timing is fixed. Mastercard generally gives the acquirer 45 calendar days from the chargeback to send a second presentment. If the issuer thinks your documents are weak, it can escalate to pre-arbitration. Mastercard makes the issuer wait at least eight calendar days for promised second presentment documents before filing pre-arbitration. Mastercard decides whether supporting documents give enough detail for everyone to understand the dispute or rebuttal.
You still have a voice at that stage. Mastercard lets the acquirer reject a pre-arbitration case when the merchant has a rebuttal to the issuer's new documents. One trap to avoid: Mastercard expects a refund to be shown in the second presentment, not in a later case filing. If you refunded the customer, say so in your first response, with the receipt to prove it.
How to reduce future chargebacks
Winning one case is good. Preventing the next is better.
Make your statement name clear. An unclear or confusing merchant name can make a cardholder believe a real charge is fraud. The name on the bill should be the name the customer knows you by.
Send order data before disputes start. Disputes are rejected when a merchant sends the required data through Verifi Order Insight before the dispute starts. That program lets the issuer see the order details early.
Deposit transactions fast. Visa's guidelines say merchants should send completed transactions to their card processor as soon as possible, preferably on the day of the sale. Visa's guidelines say merchants should review transaction receipts before depositing them.
Handle cancellations cleanly. Visa's guidelines say merchants should send the customer a notification stating that the recurring payment account has been closed.
Use the right terminal setup. Visa's guidelines say to make sure the terminal is EMV-compliant and the correct Cardholder Verification Method was obtained.
Some claims will still slip through. Ethoca describes friendly fraud as fraud committed when a person knew about or benefited from a transaction they wrongly reported as unauthorized. For those, the evidence steps above are your answer. When a customer disputes a charge with their own bank, the other side of that process is the merchant dispute view.
Read the reason code, match the proof to it, and file before the deadline on your acquirer's notice.
