A chargeback is a process through which a cardholder disputes a transaction and the payment system may reverse or return funds under applicable rules. It is different from a merchant-issued refund, although both can result in money being returned to the customer. The process, deadlines, fees, and evidence requirements depend on the card network, provider, region, and reason code.
Why chargebacks happen
Common causes include unauthorized transactions, goods not received, products materially different from the description, duplicate charges, processing errors, or confusion about a subscription. Some disputes are genuine, while others arise from misunderstandings or fraud.
Evidence that may be relevant
Depending on the dispute, a merchant may need an order receipt, product description, customer communications, delivery confirmation, refund policy shown at purchase, cancellation records, or proof that a service was provided. Evidence should be authentic, relevant, and submitted by the provider’s deadline.
Reduce preventable disputes
- Use clear product descriptions, prices, delivery estimates, and refund terms.
- Make the billing descriptor recognizable.
- Send order confirmations and shipping updates.
- Offer a visible customer-support route.
- Make subscription renewal and cancellation terms easy to understand.
- Refund promptly when a refund is appropriate.
Responding to a dispute
Read the exact reason code and deadline in your payment provider’s dashboard. Submit only evidence relevant to that reason. Do not contact a customer in a threatening way or fabricate delivery, consent, or communication records. A provider may decide the dispute under its rules even when the merchant believes the transaction was legitimate.
Monitor patterns
Track dispute rates by product, campaign, delivery method, and customer journey. A sudden increase may point to unclear billing, fulfillment problems, fraud, or misleading advertising. Fixing the underlying cause is usually more effective than treating every dispute as an isolated event.
