Chargeback

A chargeback creates both a case-management task and a cash exposure. Track the disputed principal, provider fees, response deadline and current case stage separately.

How a Chargeback Works

1. The cardholder raises a dispute with the issuer, which assesses it under the applicable process.
2. A chargeback reaches the acquirer or PSP and the merchant may be debited for the disputed amount and contractual fees.
3. The case notice identifies the reason, evidence requirements and merchant response deadline.
4. Where a response is available, the merchant can accept the dispute or contest it with relevant evidence through the provider.
5. Funds may be returned if the challenge succeeds. Further stages and finality depend on the scheme, case and provider.

Do not treat every initial debit or adverse case update as a final loss. Conversely, do not assume escalation is always available: Stripe's dispute lifecycle describes its final decision and says its platform does not support arbitration. Ask your provider what the current stage permits before incurring more evidence or escalation costs.

Chargeback Reasons

Card networks use their own reason codes. Broad categories include unauthorised transactions, authorisation problems, processing errors and goods/services disputes. These require different evidence: authentication records do not prove delivery, and proof of delivery does not resolve a duplicate-processing error.

Use the exact code and description in the case notice rather than translating between networks by number. The scheme chargeback reference provides further context; the provider's current deadline and case requirements govern the response workflow.

Monitoring and Fees

There is no single chargeback percentage that guarantees an account is safe or automatically suspended. Network programmes can use both counts and ratios, different denominators, fraud reports as well as disputes, and region-specific criteria. Acquirers and PSPs can also set contractual risk limits.

Visa's VAMP replaced its legacy dispute and fraud monitoring programmes in April 2025. Adyen's monitoring documentation describes that change and the combined metric. Mastercard operates separate programmes. Check the applicable region, measurement period, denominator and qualifying count before comparing a dashboard ratio with a network threshold.

Merchant chargeback fees come from the acquiring or PSP agreement. They are separate from network assessments and any escalation charges; neither a universal per-case fee nor a universal fine schedule follows from receiving a chargeback. Obtain the fee schedule and ask whether fees are returned after a successful defence.

Friendly Fraud

“Friendly fraud” describes first-party misuse or mistaken disputes, such as an unrecognised merchant descriptor or a purchase the cardholder later denies. It does not establish a universal share of all disputes or prove intent in an individual case.

Clear descriptors, accessible cancellation and refund paths, purchase confirmations and retrievable fulfilment records help operators investigate disputes and choose evidence. Prioritise cases by reason, evidence quality and recoverable value rather than assuming every dispute is fraudulent.
