What is Chargeback?
A forced reversal of a card payment initiated by the cardholder's issuing bank.
A chargeback is a forced reversal of a card payment initiated by the cardholder via their issuing bank.
It is a formal dispute mechanism governed by card scheme rules, providing a contractual remediation path for consumers who allege fraudulent use of their card, non-receipt of goods, or other transaction issues.
Once a dispute is filed, the issuer typically debits the transaction amount from the merchant's account via their acquirer, applying an additional, non-refundable administrative fee. This process is distinct from a simple refund, as it is adversarial and carries significant penalties if not managed correctly.
The transaction is categorised by a specific reason code which dictates the evidence required for the merchant to challenge the reversal.
The chargeback lifecycle involves several stages. It may begin with a retrieval request, where the issuer asks for more information about a transaction.
If unresolved, it becomes a formal chargeback. The merchant then has a limited window, typically 30 to 45 days, to submit a rebuttal with compelling evidence, known as representment.
If the issuer accepts the evidence, the funds are returned. If not, the case can proceed to Pre-Arbitration and then binding Arbitration, where the card scheme makes a final ruling.
A common misunderstanding is that chargebacks are a statutory consumer right; in reality, they are a system created and managed by the card schemes with contractually binding rules for all participants.
Worked example
A UK merchant sells a pair of designer trainers for £450. The customer later disputes the transaction with their bank, claiming they never received the item.
The issuer initiates a chargeback using Visa reason code 13.1 (Goods/Services Not Received). The merchant's acquirer immediately debits their account for the £450 sale amount plus a £20 chargeback fee, totalling a £470 loss.
The merchant receives a notification and has 30 days to respond.
Using their chargeback management tool, they gather evidence including the customer's order confirmation, IP address data, and crucially, the courier's proof of delivery report which includes GPS coordinates and a photograph of the parcel at the correct address. They submit this evidence bundle as representment.
The issuer reviews the evidence and, finding it compelling, reverses the chargeback. The £450 is credited back to the merchant's account, though the £20 fee is non-refundable.
Scheme notes
Visa and Mastercard operate distinct chargeback monitoring programmes. Visa's Acquirer Monitoring Program (VAMP) includes the Visa Chargeback Monitoring Program (VCMP) and the Visa Fraud Monitoring Program (VFMP).
Merchants typically enter the VCMP if they exceed 100 chargebacks and a 0.9% chargeback-to-sales ratio in a month.
Mastercard's Excessive Chargeback Program (ECP) has two tiers: Excessive Chargeback Merchant (ECM) at 100 chargebacks and 1.5% ratio, and High Excessive Chargeback Merchant (HECM) at 300 chargebacks and 3.0% ratio. Fines and remediation plans are associated with these programmes.
Representment timelines also differ slightly. American Express is known for a historically more cardmember-favouring dispute process, though it follows similar principles of evidence submission.
Why it matters for merchants
Chargebacks inflict direct financial losses: the reversed sale amount plus a non-refundable administrative fee, typically £15-£25 per incident.
High chargeback ratios, even from a small number of disputes, can trigger placement in costly scheme monitoring programmes, leading to monthly fines and the risk of account termination. This is particularly acute for high-risk merchants.
Acquirers may impose higher reserves or rolling reserves on merchants with elevated chargeback levels to mitigate their own risk. Cardflo's chargeback tooling helps merchants by automating the collection of evidence and streamlining rebuttal submissions, increasing the chances of winning representments.
Our multi-acquirer network also provides resilience, as high chargebacks on one MID can be isolated while processing continues on others.
Frequently asked
How do chargeback thresholds affect a merchant account?
Card schemes monitor the ratio of chargebacks to total transactions; if a merchant exceeds established limits, they may be placed into high-risk programmes.
These programmes often incur mandatory monthly fines and require the merchant to submit detailed remediation plans to their acquirer to avoid termination of their MID.
What is the difference between a chargeback and a retrieval request?
A retrieval request is a preliminary inquiry where the issuer asks for transaction information before deciding whether to initiate a full chargeback.
While not all disputes begin with a retrieval, responding to them promptly with valid evidence can often prevent a formal chargeback and the associated fees from being applied.
What is an acceptable chargeback ratio?
Most acquirers and card schemes consider a chargeback-to-transaction ratio below 0.9% to be acceptable.
Exceeding this threshold, especially in conjunction with a high number of disputes (e. g. , over 100 per month for Visa), can trigger placement in monitoring programmes like Visa's VCMP or Mastercard's ECP.
These programmes come with escalating monthly fines and an obligation to implement a remediation plan. Consistently staying below 0.5% is a healthy target for most businesses.
Can I prevent chargebacks completely?
It is virtually impossible to prevent all chargebacks, especially those arising from 'Friendly fraud' where a legitimate customer disputes a valid charge.
However, merchants can significantly reduce them by using clear billing descriptors, providing excellent customer service, having a clear refund policy, and using fraud prevention tools like AVS, CVV checks, and 3D Secure.
Proactive communication about delivery times and product details can also prevent disputes related to service or quality.
What happens if I lose a Chargeback Arbitration case?
If a merchant loses a chargeback case that has gone to Arbitration, the card scheme's decision is final and binding. The merchant forfeits the transaction funds and is responsible for all associated fees.
This includes the initial chargeback fee, a representment handling fee from their provider, and significant Arbitration case fees levied by the scheme, which can be as high as $500. Losing an Arbitration case also counts negatively toward the merchant's overall dispute record.
How is a chargeback different from a retrieval request?
A retrieval request, or request for information, often precedes a chargeback. It is initiated by the issuer when a cardholder questions a charge but has not yet filed a formal dispute.
The acquirer asks the merchant to provide basic transaction details, like a sales receipt. Fulfilling this request promptly with clear evidence can often resolve the cardholder's query and prevent it from escalating into a costly and damaging chargeback.
Ignoring a retrieval request almost guarantees it will become a chargeback.
Is 'Friendly fraud' a legitimate reason for a chargeback?
No, 'Friendly fraud' is an industry term for when a cardholder disputes a legitimate transaction, either due to confusion, forgetfulness, or intentional deception to get something for free.
The cardholder will use a valid chargeback reason code, such as 'Goods Not Received' or 'Transaction Not Recognised', even though the claim is false.
Merchants must fight this type of fraud through representment by providing compelling evidence that the cardholder authorised and received the goods or services as described. This is a significant challenge for e-commerce merchants.
