Chargebacks and fraud

What is a chargeback?

Direct answer

A chargeback is a card-payment reversal initiated through the issuing bank and card-network dispute process after a cardholder or issuer challenges a transaction. The merchant may receive a reason code, deadline, and opportunity to provide specified evidence. A chargeback is different from a merchant-issued refund and can affect funds, fees, monitoring metrics, and account risk.

Key facts

  • Reason codes describe the dispute category.
  • Response windows are time-sensitive.
  • Winning one dispute does not replace prevention work.

The dispute path

The issuer raises the dispute through the network. The acquirer or dispute platform notifies the merchant, who may accept it or respond with evidence when the rules allow. Later stages can include pre-arbitration or arbitration.

Evidence should match the reason

Useful material can include order details, authorization results, proof of delivery or service, refund policy, customer communication, device data, and transaction-specific records. Irrelevant volume weakens a response.

When the answer changes

  • Rights, deadlines, and evidence vary by network and reason code.
  • Some fraud or compliance conditions limit representment.

Common mistakes

  • Confusing an inquiry or retrieval with a chargeback.
  • Sending a generic evidence packet.

What to verify

  1. Record the reason code and exact deadline.
  2. Use current network guidance and retain submission proof.
