What is Dispute?
Any cardholder-initiated challenge to a transaction, covers retrieval requests, chargebacks, pre-arbitration, and arbitration.
A dispute is the overarching, card scheme-governed process a cardholder uses to formally challenge a transaction via their issuing bank.
While often used as a synonym for 'Chargeback', the term 'Dispute' covers the entire lifecycle, which may begin with a retrieval request (an issuer's enquiry for more information about a transaction) and can escalate through to a chargeback, Pre-Arbitration, and ultimately, binding Arbitration.
The process is initiated when a cardholder contacts their bank about a charge they do not recognise, did not authorise, or for which goods or services were not received as described.
The issuer then translates this complaint into a specific reason code and submits the dispute to the acquirer through the relevant card scheme network, such as Visa Resolve Online (VRO) or Mastercard's MasterCom.
The acquirer is notified of the dispute and provisionally debits the merchant's account for the transaction amount. The merchant is then given a limited window, typically 14 to 30 days, to respond by submitting a 'Representment'.
This is a package of compelling evidence intended to disprove the cardholder's claim. Evidence might include proof of delivery, AVS/CVV results, 3D Secure authentication data, and records of customer communication.
A common misunderstanding is that a dispute always involves fraud; in reality, disputes are categorised into fraud, authorisation, processing errors, and consumer disputes, each with distinct rules and evidentiary requirements.
If the merchant's representment is successful, the funds are returned.
If the issuer rejects the representment, the case moves to Pre-Arbitration, giving the merchant a final chance to accept liability before incurring the significant costs and binding decision of a formal Arbitration case filed with the card scheme.
The entire framework is designed to protect consumers but places a significant operational and financial burden on merchants.
Worked example
A merchant sells a designer handbag for £850. A month later, the cardholder initiates a dispute, claiming the transaction was fraudulent.
The issuer, using Mastercard's MasterCom system, raises a chargeback with reason code 4837 (No Cardholder authorisation). The merchant's acquirer, Cardflo, receives the dispute and immediately debits the merchant's account for £850, plus a non-refundable £20 dispute fee.
The merchant is notified via their dashboard and has a 20-day window to respond. The original transaction was authenticated with 3D Secure, and the merchant has shipping confirmation with a signature upon delivery to the AVS-matched billing address.
The merchant uploads this compelling evidence. Cardflo's dispute team submits the representment package.
After 30 days, Mastercard rules in the merchant's favour based on the strong evidence. The £850 is credited back to the merchant's settlement account.
The £20 fee remains, representing the administrative cost of the process.
Scheme notes
Visa and Mastercard manage disputes through different platforms and have distinct programmes. Visa uses Visa Resolve Online (VRO) and organises its rules under the Visa Dispute Resolution Initiative (VDRI).
Key monitoring programmes include the Visa Dispute Monitoring Program (VDMP) and Visa Fraud Monitoring Program (VFMP), which have thresholds like 0.9% dispute ratio and 100 disputes per month. Mastercard uses the MasterCom system and runs the Excessive Chargeback Program (ECP).
Representment response times also differ; Visa often allows merchants around 20 days, whereas Mastercard can provide up to 45 days. Visa's Compelling Evidence 3.0 (CE3.0) rules have created a more structured way for merchants to fight Friendly fraud by providing historical transaction data.
American Express operates a closed-loop system, handling disputes internally with generally shorter response windows for merchants, often around 20 days.
Why it matters for merchants
Disputes carry a direct financial cost, comprising the loss of the transaction revenue, the product cost, and a non-refundable administrative fee per dispute, typically £15-£30.
Exceeding scheme thresholds (e. g. , the Visa Dispute Monitoring Program's 0.9% count-to-sales ratio) can lead to monthly fines, increased acquirer scrutiny, higher processing fees, and ultimately, the risk of account termination.
There is also a significant operational overhead required to investigate each case and compile evidence for representment. Cardflo's chargeback tooling provides merchants with real-time dispute alerts, automated evidence collection from transaction data, and analytics to identify trends in reason codes or customer behaviour.
This helps merchants to not only fight disputes more effectively but also to address the root causes and lower their overall dispute ratio.
Frequently asked
How do new scheme updates like Visa CE 3.0 affect the dispute process?
These updates allow merchants to combat first-party fraud by providing historical transaction data that proves a previous relationship with the customer.
If a merchant can show two prior undisputed transactions that share the same IP address or device ID as the disputed one, the issuer may be required to block the dispute at the pre-chargeback stage.
What happens if a merchant exceeds the monthly dispute threshold?
Exceeding thresholds set by schemes, such as the Visa Dispute Monitoring Program (VDMP), often results in significant monthly fines and higher interchange costs. Continued non-compliance can lead to the termination of the Merchant Identification Number (MID) by the acquirer.
What is the difference between a retrieval request and a chargeback?
A retrieval request is a non-financial inquiry from the issuer for more information about a transaction, typically a copy of the sales receipt. It precedes a chargeback and does not involve the movement of funds.
A chargeback is a formal, financial dispute where funds are immediately debited from the merchant. Under Visa's VDRI rules, most retrieval requests have been eliminated in favour of a direct-to-chargeback workflow to streamline the process, though they still exist for certain transaction types.
How long do I actually have to respond to a dispute?
The card scheme rules dictate the maximum timeframe, which is often 20-30 days for Visa and up to 45 days for Mastercard. However, your acquirer will set a shorter internal deadline, for example, 15 or 20 days.
This is to ensure they have enough time to review your evidence, correctly format the representment package, and submit it to the scheme network before the final cut-off. Always adhere to your acquirer's deadline.
Can my merchant account be penalised for just a handful of chargebacks?
Penalties are based on ratios, not just absolute numbers. For instance, the standard Visa Dispute Monitoring Program (VDMP) threshold is triggered if a merchant has both 100 or more disputes and a dispute-to-sales ratio of 0.9% or higher in a single month.
Therefore, a merchant with high volume could have over 100 chargebacks but remain below the ratio threshold, while a smaller merchant could breach the 0.9% ratio with fewer than 100 disputes but not enter the programme until they also hit the count threshold.
What happens in Pre-Arbitration and should I fight it?
Pre-Arbitration, or a 'second chargeback', occurs when the issuer rejects your representment. The acquirer will re-debit your account.
You have two choices: accept liability or escalate to formal Arbitration with the card scheme. Escalating involves non-refundable filing fees (around £200-£400 from the acquirer and an additional $250 from the scheme) and a binding ruling.
You should only proceed to Arbitration if your evidence is exceptionally strong and the transaction value justifies the costs and risks, as the loser is typically liable for all fees.
If I win a dispute, is the chargeback fee refunded?
No, in almost all cases the chargeback fee charged by the acquirer is non-refundable. This fee covers the administrative costs incurred by the acquirer for managing the case, including reviewing evidence and submitting the representment through the scheme's platform.
The fee is levied for handling the dispute process itself, regardless of whether the final outcome is in the merchant's favour.
