Chargebacks, Disputes and Representment: The Money Path When a Payment Goes Wrong

Mastercard has a 45-day filing period, and its rules treat arbitration as the final, network-decided stage.

Once a chargeback is filed, both Visa and Mastercard follow a rules-driven sequence that includes representment (the merchant’s response) and arbitration (the network’s decision). Under Mastercard’s rules, a cardholder can only file for scheme arbitration after the disputes process is complete. During this final stage, the card network makes the binding call on who will bear the disputed transaction amount.

Who Can Still Move the Case

If a chargeback is valid under a reason code and is properly documented, it can be escalated further, according to Mastercard's rules. The merchant has a window to respond:

• The pre-arbitration case, or representment, lets the merchant dispute a cardholder claim within a deadline.
• If the issuing bank upholds the chargeback, the merchant can then move to scheme arbitration.

Under Mastercard’s rules, a cardholder can file an arbitration case only if chargeback cycles have closed and the dispute remains unresolved in the cardholder’s favor. Network rules provide limited grounds for merchants to pursue scheme arbitration, adding to the pressure to get response deadlines and paperwork right.

What Evidence Counts

To dispute a chargeback, either the merchant or their bank must prove that the original transaction was legitimate. Visa’s compelling evidence process includes these examples:

• Photographs or emails linking the cardholder to the delivered goods
• Proof of delivery
• IP address and device ID numbers
• A full name associated with the transaction

In a physical-money chargeback case, a signature is not considered compelling evidence of delivery. A merchant challenging a chargeback on e-commerce transactions can submit a combined account profile and IP data or device ID that matches the cardholder’s address and identity.

Who Decides and When

After a chargeback claim closes in the cardholder's favor, the merchant’s bank can dispute the claim, supporting the transaction with documentation, like the compelling evidence outlined above. The chargeback claim can be disputed twice.

Network procedure guides for each scheme establish how much time is provided at each stage of the chargeback, representment, and arbitration cycles. Chargeback cycles must be completed before a cardholder can file an arbitration case. The card network makes the binding final decision on arbitration.

The Cost of Escalation

Arbitration is the route for a chargeback that cannot be resolved through two regular chargeback cycles. The fee for the process is assessed to the losing member. Both Visa and Mastercard issue guides that differ in how fee amounts are expressed. The highest fee assessed to an acquirer or issuer is a variable fee per case.

Fraud and Liability Pressure

While evidence such as a customer signature on delivery is not enough to justify turning back a chargeback, expanded data offered by a merchant may be sufficient if it is tied to specific chargeback reason codes. The documentation must address the allegations listed. Visa’s recent compelling evidence rules explicitly state that this evidence may include a photograph of the receiver with merchandise, proving that the cardholder is in possession of the items, or an email aligning the purchaser with the cardholder account.

Where the Process Breaks

Merchants often believe chargebacks are punished by deduction against the reserve, on a ratio basis,. Knowing when to escalate a chargeback is a useful skill. Some merchants might escalate a chargeback because they sense that the cardholder will file an arbitration claim, while others will avoid it to save costs. Regardless of which route you choose, your decision will rely on the chargeback reason and the strength of the documentation you can supply. Failing to dispute a chargeback within time deadlines will mean the loss of the transaction and affect your long-term reserve amounts.

Final Judgment from the Networks

In every network-defined chargeback process, the chargeback cycle is the end. Once a cardholder is given a refund, or a merchant loses an arbitration, the network will not reverse the transaction. If no compelling evidence is filed within the specified time limit, the case ends with the cardholder receiving a refund. If compelling evidence is filed with an issuing bank, the refutation is closed in the merchant’s favor. Arbitration is where a final decision is made. The card network considers the evidence, which includes the reason code cited, and decides who wins. The decision is binding, and the availability of this process at the scheme level and at the issuer or acquirer level varies by network.
