Also called: Cardholder dispute, Dispute, Disputed transaction, Payment dispute
What a chargeback is
A chargeback reverses a completed card payment after a customer asks their bank to dispute it. The issuing bank reviews the claim. If it rules for the customer, the disputed amount is taken from your business and returned to the cardholder. This is different from a refund, which you initiate directly.
Common reasons include an unrecognized charge, suspected fraud, a duplicate payment, or goods that did not arrive or match their description. A customer can also dispute a legitimate purchase after forgetting it or not recognizing your business name. That is often called friendly fraud.
A chargeback can cost you the sale, the product, a fee, and the time spent contesting it.
How the dispute process works
The customer contacts the issuing bank, which opens the dispute and notifies your acquiring bank. Your processor or acquirer sends you the notice and a deadline. You can accept the chargeback or challenge it with evidence such as receipts, delivery confirmation, order details, or customer messages. The issuing bank reviews the evidence and decides the outcome.
Visa and Mastercard rules generally give cardholders 120 calendar days to dispute a transaction. Some delayed-delivery cases have outer limits up to 540 days. Your response deadline is set by your processor and commonly falls within 20 to 30 days. Miss it and you lose the chance to challenge the case.
What a chargeback costs your business
You risk losing the sale amount, the goods or service already provided, and a chargeback fee set by your acquirer. Dispute work also takes staff time. Mastercard's 2026 research puts merchants' average internal and third-party cost at $128 per chargeback, excluding the value of goods or services already provided.
The fee is not the only cost to track. Compare each chargeback notice with the transaction and your processing statement so you can reconcile the amount withdrawn and any separate fee. Do not treat every case as a lost sale: evidence can help you recover the transaction amount if the issuer rules in your favor.
Why your dispute rate matters
High dispute levels can lead to network monitoring and more work to keep your processing account in good standing. As of April 1, 2026, Visa's US VAMP excessive threshold is a 1.5% ratio, with at least 1,500 combined fraud reports and disputes in a month. The ratio counts TC40 fraud reports and TC15 disputes against settled card-not-present transactions.
Mastercard's Excessive Chargeback Program uses separate thresholds. As of 2026, its Excessive Chargeback Merchant level starts at 100 chargebacks and a 1.5% monthly ratio; its High Excessive level starts at 300 chargebacks and a 3.0% ratio. Track counts and ratios together, because crossing both parts of a threshold matters.
Where preventable disputes start
Customers dispute charges they do not recognize, so make the name on their card statement match the business they remember buying from. Clear receipts, accurate product descriptions, visible return terms, and timely shipping updates address common sources of confusion. For subscriptions, make cancellation instructions easy to find.
When a dispute arrives, match its reason code to the requested evidence and submit before the deadline. A receipt alone may not answer a claim that an order never arrived, while tracking confirmation may not resolve a claim about an incorrect amount.
What you can actually change
- Track the deadline. Record the response date as soon as you receive a notice. The processor's deadline controls, and missing it forfeits your chance to challenge the dispute.
- Match evidence to the claim. Use the reason code to choose relevant records, such as receipts, delivery confirmation, authorization details, or customer communications. Submit them before the deadline.
- Reduce confusion. Use a recognizable business name on statements, send clear receipts, explain return terms, and communicate shipping or subscription changes promptly.
- Review repeat causes. Group disputes by reason code, sales channel, and product. Fix recurring issues such as unclear billing descriptors, duplicate charges, or missed delivery expectations.
Frequently asked questions
How long does a customer have to file a chargeback?
Visa and Mastercard rules generally allow 120 calendar days from the transaction or expected delivery date. Some delayed-delivery cases have outer limits up to 540 days. The applicable period depends on the case, so use the dispute notice and reason code to understand the claim.
Can I fight a chargeback?
Yes. You can submit evidence through your processor or acquirer before the response deadline. Match the records to the reason for the dispute, then keep proof of submission. The issuing bank reviews the case and decides whether to uphold or reverse the chargeback.
Is a chargeback the same as a refund?
No. You issue a refund directly to a customer. A chargeback starts when the customer asks their bank to dispute a card payment, and the disputed amount can be withdrawn while the bank reviews the case. A refund can resolve a customer complaint before it becomes a chargeback.
What is the difference between a dispute and a chargeback?
A dispute begins when a cardholder questions a transaction with their bank. If the process proceeds to a payment reversal against your business, it is a chargeback. In everyday use, businesses and card networks often use the terms interchangeably.
