How Does the Chargeback Process Work?
A chargeback begins when a cardholder asks the card issuer to dispute a payment. The issuer, card network, acquirer or processor, and merchant then exchange case information under the rules that apply to that transaction. The exact path varies, but merchants can prepare for the process by understanding each stage, reading the live case record, and responding with focused evidence by the deadline supplied by their provider.
Process overview
The typical chargeback journey
Visa describes a dispute as a reversal of all or part of a transaction's value from the issuer to the acquirer, usually followed by a debit to the merchant. Mastercard and payment providers use their own terminology and case stages, so the merchant's actual portal or notice remains the operational source of truth.
1. The customer contacts the issuer
The cardholder questions a payment for a reason such as suspected fraud, non-receipt, cancellation, a processing error, or a product or service concern. The issuer reviews the claim and decides whether to open a formal dispute under an available reason or condition.
2. The issuer initiates the dispute
When the claim qualifies, the issuer sends the dispute through the card-network process. The disputed amount may be provisionally credited to the cardholder, while the merchant side can be debited for the amount and any provider-assessed fee.
3. The merchant receives notice
The acquirer, processor, gateway, or payment platform presents the dispute to the merchant. The notice normally identifies the transaction, disputed amount, claim category or reason, response options, required evidence, and merchant-facing deadline.
4. The merchant chooses a response
The merchant can generally accept the dispute or challenge it when authentic, relevant records support a response. A challenge is often called a dispute response or representment. It is not a guarantee that the funds will be returned.
5. Evidence is reviewed
The provider routes the merchant's response through the applicable process. The issuer evaluates whether the submission answers the cardholder's claim and meets the relevant network requirements.
6. The case is resolved or continues
The dispute may be decided for either side, withdrawn, or move into another stage. Some cases can progress to pre-arbitration, arbitration, or a network-specific equivalent. Availability, responsibility, cost, and timing depend on the case and provider.
First response
What to do when a notice arrives
Confirm the case details
Match the case to the original payment and verify the amount, currency, card brand, transaction date, customer, order or invoice, claim reason, and deadline. Check whether the case covers the full payment or only part of it.
Protect the deadline
Assign an owner and calculate an internal due date earlier than the provider cutoff. Visa advises merchants to respond swiftly when contacted by an acquirer. A late response can close the available response path regardless of the underlying facts.
Check for related activity
Look for a pending refund, prior dispute, duplicate charge, cancellation request, delivery issue, support conversation, fraud signal, or other payment tied to the same order. Avoid issuing a second reimbursement without checking the provider's instructions.
Choose deliberately
Accept a valid claim or prepare a challenge only when the records support it. Consider the dispute reason, available evidence, customer history, operational cost, and any additional escalation risk. Do not challenge every case automatically.
Evidence
Build a response around the stated reason
Strong evidence is authentic, legible, transaction-specific, and directly connected to the issue the issuer is reviewing. More pages do not necessarily make a stronger response.
Transaction records
Include relevant receipts, order or invoice details, transaction identifiers, authorization information supplied by the provider, and a clear explanation of how the records connect to the disputed payment.
Customer agreement
When relevant, provide the terms shown at the time of purchase, the customer's affirmative acceptance, and the applicable return, refund, cancellation, or recurring-billing disclosure. Avoid substituting a newer policy.
Delivery or service records
Use appropriate shipment, pickup, access, usage, appointment, work-completion, or customer-communication records. The useful record depends on what was sold and the claim being answered.
Focused explanation
Write a brief factual summary that identifies the transaction, addresses the specific claim, and points to each supporting item. Avoid speculation, emotional language, irrelevant history, and unsupported conclusions.
Decision path
Accept, challenge, or escalate with care
Accept when the claim is supported
Acceptance may be appropriate when the merchant confirms fraud, non-delivery, an unprocessed cancellation, a duplicate charge, a billing error, or another valid issue. Record the root cause and corrective action.
Challenge when records answer the claim
A challenge can be reasonable when the transaction is recognized and the merchant has the evidence requested for that dispute reason. Submit through the designated provider channel and preserve confirmation of delivery.
Review any next stage separately
If the issuer rejects a response or introduces new information, do not simply resend the same packet. Read the new case stage, understand any additional cost or liability, and follow the acquirer's current instructions before proceeding.
Do not promise an outcome
The merchant's provider facilitates the response, but the merchant does not control the issuer or network decision. Stripe's current documentation makes this distinction explicit for disputes handled on its platform.
Operations
Create a repeatable dispute workflow
Centralize notifications
Route portal, email, webhook, and processor notices to a monitored queue. Maintain backup ownership for weekends, holidays, and staff absences.
Use reason-based checklists
Map common claim types to the systems and records needed to investigate them, while allowing each case to be reviewed on its own facts.
Protect sensitive data
Use approved provider channels and submit only what the case requires. Do not place complete card numbers, passwords, bank credentials, or secret API keys in general forms or informal correspondence.
Learn from outcomes
Track dispute causes, response decisions, missed deadlines, evidence gaps, and operational fixes. Use patterns to improve descriptors, fulfillment, support, cancellation, and transaction records.

Common questions
Chargeback process FAQ
Is a chargeback the same as a refund?
No. A merchant initiates a refund through its payment workflow, while an issuer initiates a dispute after a cardholder contests a payment. The two can overlap, so related activity should be checked before money is moved again.
Who decides a chargeback?
The responsible issuer and applicable network process determine the outcome based on the claim, rules, and submitted information. The acquirer or payment provider passes notices and responses between participants.
What happens if the merchant does not respond?
If no response is submitted by the provider's deadline, the merchant generally loses that response opportunity and the dispute debit can stand. The exact status and next options depend on the provider and case.
Can every chargeback be challenged?
No. Response rights and evidence requirements depend on the case. Even when a challenge is available, accepting a valid claim may be the accurate and efficient choice.
