A chargeback is a forced reversal of a card transaction initiated by the cardholder through their issuing bank when they believe a charge is incorrect, unauthorised, or otherwise problematic.
Instead of asking the merchant directly for a refund, the cardholder files a dispute with their card issuer. If the dispute meets the card network’s rules, the issuer can reverse the transaction and return the funds to the cardholder’s account, debiting the merchant’s account in the process.
How a chargeback works
A chargeback is a formal, rules-based process governed by card networks and local regulations. It involves the cardholder, the issuing bank, the card network, the merchant’s acquiring bank, and the merchant.
The typical flow looks like this:
- Cardholder notices a problem
The cardholder sees a transaction on their statement that they believe is fraudulent, incorrect, or not resolved by the merchant. - Cardholder files a dispute
The cardholder contacts their issuing bank (via app, online banking, phone, or branch) and submits a dispute with details and any supporting evidence. - Issuer reviews and may issue provisional credit
The issuing bank reviews the claim. In some cases, it may provide a temporary or provisional credit while the investigation is ongoing. - Issuer initiates the chargeback
If the dispute meets the criteria under card scheme rules, the issuer initiates a chargeback and sends it through the card network to the merchant’s acquirer. - Merchant is notified and can respond
The merchant receives the chargeback notification and can either accept it or contest it by submitting evidence (for example, proof of delivery, transaction logs, communication with the customer, or authorisation records). - Issuer or network makes a decision
The issuing bank reviews the merchant’s evidence and makes a final decision. If the dispute remains unresolved, it may escalate to pre‑arbitration or arbitration through the card network, depending on the scheme rules. - Final outcome
If the chargeback is upheld, the funds remain with the cardholder and the merchant bears the loss (plus any applicable chargeback fees). If the chargeback is reversed in favour of the merchant, the provisional credit (if any) is removed and the funds are returned to the merchant.
The entire process can take from several weeks to a few months, depending on the card network, the complexity of the case, and how quickly each party responds.
Common reasons for chargebacks
Cardholders can file chargebacks for a range of reasons, typically grouped into broad categories:
- Fraudulent or unauthorised transactions
The cardholder did not make or authorise the transaction. - Billing errors
Duplicate charges, incorrect amounts, or charges for cancelled subscriptions or recurring payments that should have stopped. - Product or service not received
The merchant did not deliver the goods or services as promised. - Product or service not as described
The item received is significantly different from what was advertised, damaged, defective, or materially misdescribed. - Merchant issues
The merchant is unresponsive, refuses a valid refund, or has ceased trading without delivering what was paid for. - Processing errors
Technical or operational mistakes such as wrong currency, wrong card charged, or failure to follow network rules.
Each card network defines specific reason codes that map to these scenarios. The issuer selects the most appropriate reason code when filing the chargeback.
Chargeback vs refund
A chargeback and a refund both result in money returning to the cardholder, but they follow very different paths.
| Term | Who initiates it | When it is used | Typical speed |
| Refund | Merchant | When the merchant agrees to return money after a return, cancellation, or service issue | Usually faster, as it is a direct merchant action |
| Chargeback | Cardholder via their issuing bank | When the cardholder disputes a transaction and the merchant does not resolve it, or the charge is unauthorised or fraudulent | Slower, as it follows a formal dispute process |
A refund is usually the simpler and preferred option when the merchant is cooperative. A chargeback is typically used when:
- The merchant does not respond or refuses to refund.
- The transaction appears to be fraudulent.
- The cardholder cannot resolve the issue directly with the merchant.
- The charge relates to a billing error or unauthorised recurring payment.
Chargeback vs reversal
A chargeback is also different from a payment reversal.
- Reversal
A reversal cancels or unwinds a transaction before or around settlement, often while it is still pending. It may happen due to a failed authorisation, a duplicate authorisation, or a merchant void. - Chargeback
A chargeback occurs after the transaction has been completed and posted. It is a dispute-driven, forced reversal initiated by the cardholder and their issuer, not a routine operational correction.
In practice, reversals are part of normal payment processing, while chargebacks are part of a consumer protection and dispute resolution framework.
Provisional credit and final outcome
During a chargeback investigation, the issuer may provide a provisional or temporary credit to the cardholder’s account. This is not guaranteed and depends on the issuer’s policies and the nature of the dispute.
- If the chargeback is upheld, the provisional credit becomes permanent.
- If the chargeback is rejected in favour of the merchant, the provisional credit (if any) is removed and the funds are debited from the cardholder’s account again.
The final decision is based on the evidence submitted by both the cardholder and the merchant, as well as the applicable card network rules and local regulations.
Timelines and limits
Chargeback timelines vary by issuer, card network, and jurisdiction.
- Cardholders typically have a limited window to file a dispute, often measured in days or months from the transaction date or statement date.
- Issuers must complete their investigation within a defined period under applicable regulations, though exact timeframes differ by market and card scheme.
- Merchants usually have a set number of days to respond to a chargeback with evidence.
- If a case escalates to arbitration, additional time and fees may apply.
Users should file disputes as soon as they identify a problem and keep all relevant documentation (receipts, correspondence, order confirmations, delivery proofs, screenshots, and so on).
Impact on merchants and cardholders
For merchants
Chargebacks can carry financial and operational consequences:
- Loss of the disputed amount.
- Chargeback fees from their acquirer or payment processor.
- Increased chargeback ratios, which can affect pricing, risk classification, or even the ability to continue accepting card payments if ratios become too high.
For cardholders
Chargebacks are a consumer protection tool, but they should be used responsibly:
- They help recover funds in cases of fraud, billing errors, or unresolved merchant issues.
- Misusing chargebacks (for example, disputing legitimate charges without cause) can lead to account reviews or restrictions by the issuer.
- Cardholders are expected to attempt to resolve issues with the merchant first when appropriate, and to provide accurate information when filing a dispute.
