The Chargeback Dispute Timeline

A chargeback dispute is not a negotiation. It is a sequence of stages with fixed deadlines governed by card network operating rules. Each stage opens a window for a specific action. When that window closes, it closes permanently. A merchant who submits representment on day 31 for a Visa dispute has the same outcome as a merchant who does nothing: the chargeback stands and the funds are not returned.

Understanding the timeline is not just about knowing deadlines. It is about understanding that the full dispute cycle can run for 75 to 150 days depending on how far it escalates, and that each stage has its own evidence rules, cost structure, and strategic decision point. Most disputes resolve before arbitration. The ones that do not become significantly more expensive for whichever party loses.

Stage One: The Cardholder Files a Dispute

The timeline starts the moment a cardholder contacts their issuing bank to dispute a transaction. The issuer creates a formal dispute record, grants the cardholder provisional credit, and sends the dispute through the card network to the acquiring bank. The acquiring bank notifies the merchant. Funds are reversed from the merchant’s account at this point, not after a finding.

For both Visa and Mastercard, cardholders have 120 calendar days from the transaction date or the expected delivery date, whichever is later, to initiate a dispute. For Visa authorization-related codes, the window shortens to 75 days. Visa also has an outer limit of 540 calendar days for pre-orders and delayed delivery scenarios, which is why a merchant can receive a dispute nearly 18 months after a transaction settled.

The 120-day window is measured from the transaction date for most dispute types, not the statement date. A transaction processed on June 1 can generate a dispute notification arriving on September 28 at the outer edge of the standard window. Merchants who purge transaction records after 90 days are already missing documentation for live disputes when those notifications arrive.

Stage Two: The Merchant Responds with Representment

Once the chargeback notification reaches the merchant, the representment window opens. For Visa disputes, the merchant has 30 calendar days from the chargeback processing date to submit a representment package. For Mastercard disputes, the window is 45 calendar days.

Both deadlines run from the chargeback processing date, not the date the merchant receives notification. A processor who takes five days to notify the merchant of a Visa chargeback has already consumed five of the merchant’s 30 days. Some processors set internal deadlines shorter than the network deadlines to give themselves time to compile and transmit the package to the acquirer. The actual response window available to the merchant may be 20 days or fewer even when the network allows 30.

The representment package must address the specific reason code attached to the dispute. Evidence that does not speak to the code has no effect on the outcome. If the merchant does not respond within the window, the chargeback is automatically confirmed and the case closes against the merchant.

Stage Three: The Issuer Reviews the Evidence

After the merchant submits representment, the issuing bank reviews the evidence package. The issuer has 30 to 45 days to complete this review depending on the network and dispute type.

The first outcome is that the issuer accepts the representment and withdraws the dispute. The disputed funds are returned to the merchant and the case closes in the merchant’s favor.

The second outcome is that the issuer rejects the representment and files a pre-arbitration chargeback. This is the issuer asserting that the merchant’s evidence does not change the outcome and that the dispute should be upheld.

The third outcome is that the issuer takes no action within their review window. An issuer that does not respond within the allowed period is typically treated as having accepted the merchant’s representment, and the funds are returned.

Stage Four: Pre-Arbitration

When the issuer files a pre-arbitration chargeback after rejecting the merchant’s representment, the merchant has another response window. Under Visa’s rules, the merchant has 30 calendar days to respond to pre-arbitration. Under Mastercard’s rules, the window is 45 calendar days.

At pre-arbitration, the merchant has three options. Accepting the chargeback ends the dispute against the merchant with funds not returned. Providing additional evidence gives the issuer another opportunity to reconsider. Proceeding to arbitration escalates the dispute to the card network for a binding ruling.

The decision at pre-arbitration is a financial calculation. If the disputed amount is small relative to arbitration fees, accepting the loss at pre-arbitration is cheaper than escalating. If the disputed amount is significant and the merchant’s evidence is strong, arbitration may be the correct path.

Stage Five: Card Network Arbitration

Arbitration is the final stage of the chargeback dispute process. It is a binding ruling by the card network adjudicator based on all evidence submitted in prior stages. No new evidence is permitted at arbitration. The ruling is final and both parties are bound by it.

For Visa, the merchant must file for arbitration within 10 business days of the pre-arbitration decision. Visa’s Dispute Management Guidelines for Merchants, published at by.visa.com, cover the full process, evidence requirements, and filing procedures. Visa’s arbitration filing fee is $500. If the merchant loses at arbitration, the $500 is not refunded and the merchant remains liable for the disputed amount.

For Mastercard, the arbitration filing window is 45 calendar days from the pre-arbitration stage. Mastercard’s arbitration fee is $575 plus a $250 administrative fee, totaling $825 to initiate. Mastercard eliminated the 10-day acquirer counter-response window in October 2024. Mastercard’s Dispute Resolution Management team now begins its review immediately upon case acceptance.

The card network typically issues its arbitration ruling within 45 to 90 days of accepting the case. The full dispute cycle from first chargeback through arbitration ruling runs approximately 75 to 150 days depending on the network, the complexity of the case, and how quickly each party responds within their windows.

The Processor Layer and Why Deadlines Shrink

Every deadline above is a card network deadline. The merchant’s actual deadline is typically shorter because of the processor layer sitting between the merchant and the network.

The acquiring processor must review the merchant’s submission, compile it into the correct format for network transmission, and submit it before the network deadline. Processors who require submissions seven to ten days before the network deadline leave merchants with 20 days or fewer to respond to Visa chargebacks.

The practical deadline for a Visa chargeback is typically 14 to 21 days from notification, not 30. The practical deadline for a Mastercard chargeback is typically 30 to 35 days, not 45. Reading the specific deadline in the processor dashboard rather than assuming the network deadline is the operationally safe approach.

Managing the Timeline Across Multiple Disputes

Merchants with significant dispute volume need a systematic approach to deadline tracking because multiple disputes running simultaneously at different stages can produce conflicting deadlines within the same week.

A dispute tracking system that logs the chargeback notification date, the network deadline, the processor internal deadline, the submission date, and the current stage for every open dispute is the minimum operational requirement. Merchants who manage disputes in email inboxes or spreadsheets without deadline fields miss representment windows on winnable cases.

Frequently Asked Questions

How long does a cardholder have to file a chargeback?

Cardholders have 120 calendar days from the transaction date or the expected delivery date, whichever is later, for most Visa and Mastercard dispute types. Visa authorization-related codes have a shorter 75-day window. Visa also has an outer limit of 540 calendar days for pre-orders and delayed delivery disputes, meaning a merchant can receive a chargeback notification nearly 18 months after a transaction settled.

How long does a merchant have to respond to a chargeback?

Visa gives merchants 30 calendar days from the chargeback processing date to submit representment. Mastercard gives merchants 45 calendar days. Both deadlines run from the processing date, not the notification date, and processor internal deadlines are typically shorter than the network deadlines. A Visa merchant’s practical response window is often 14 to 21 days from notification.

What happens if a merchant misses the representment deadline?

Missing the representment deadline results in an automatic loss. The chargeback is confirmed and the disputed funds are not returned, regardless of how strong the merchant’s evidence would have been. There is no extension or appeal available for a missed representment window.

How long does the full chargeback dispute process take?

A dispute that resolves at representment closes in 60 to 90 days from the original chargeback notification. A dispute that escalates to pre-arbitration runs 90 to 120 days. A dispute that goes to full arbitration can take 75 to 150 days from first chargeback to final ruling, depending on the network and how quickly each party responds within their windows.
