Mastercard Chargeback ProcessA Six-Step Process That Becomes Costlier Over Time

Examining Each Step in the Mastercard Chargeback Process

Every time you receive a chargeback, you’ll have to participate in an involuntary and unwelcome process that involves you, your customer, the banks representing each party, and Mastercard.

At any stage of the process, you can choose to accept the chargeback… which means you automatically lose the dispute. Or, you can fight on, knowing you risk incurring more fees and additional complications if you lose.

In this chapter, we’ll take a closer look at the Mastercard chargeback process so that you know what to expect.

A Quick Look at the Mastercard Chargeback Process

Every card network’s chargeback process involves several steps. But they’re each different in their own way.

Mastercard’s chargeback process can be thought of in its simplest form as a five-step sequence that begins when the cardholder files a dispute with their issuer, and ends at arbitration (or whenever you accept the outcome of the chargeback), whichever comes first. Here are the steps involved:

First presentment is the original transaction. Specifically, the submission of a transaction to the cardholder’s bank for payment. When a customer makes a purchase, the transaction data flows through Mastercard’s network to the issuing bank, which debits the cardholder’s account and credits it to your account.

The completeness and accuracy of data submitted during first presentment directly impacts dispute outcomes. Clear merchant descriptors, accurate transaction amounts, proper authorization codes, and complete purchase details make it easier for cardholders to recognize legitimate charges (preventing many chargebacks before they start).

After first presentment, the transaction enters the funding stage (also called clearing or settlement). During funding, the cardholder’s account is officially debited and funds flow through the network to your account. For most transactions, settlement occurs within 1-3 business days, though timing varies by processor and merchant agreement.

Most chargebacks aren’t filed until weeks or months after funding. Cardholders may not review statements immediately, or they may wait to see if expected merchandise arrives.

This delay creates a dangerous gap: you’ve already received the funds, fulfilled the order, and booked your revenue, before discovering the transaction will be disputed. Understanding that funding is a temporary state — not a guarantee of permanent payment — is essential for proper revenue recognition and chargeback reserve planning.

The bank reverses the initial charge. Mastercard forwards the Notification of Chargeback (NoC) to the acquiring bank, who notifies you, typically through email alerts or processor dashboard notifications. This notification includes the reason code, transaction details, and deadline for response. The funds are debited from your account, usually before you even see the notification, plus a chargeback fee ($20-$50 on average).

At this stage in the Mastercard chargeback process, you have three options:

• Accept the Chargeback: Immediate resolution, but guaranteed loss of transaction revenue, plus fees and a hit to your chargeback ratio.
• Issue a Refund: Still lose revenue, but avoid fee and prevent chargeback from counting toward ratio if done before chargeback is finalized.
• Submit Second Presentment: The chargeback moves forward to the next step. This requires evidence and means more time invested on your part.

Your decision should weigh the transaction value against the cost to fight (typically $40-$80 in labor), the likelihood of success based on the reason code, and whether the chargeback affects monitoring program thresholds. The reason code determines what evidence Mastercard will accept. Fraud claims, for instance, require different documentation than processing errors.

This is also called representment, because you literally “re-present” the transaction by submitting it a second time (along with evidence to refute the cardholder’s claim).

You need documentation that directly refutes the cardholder’s claim according to the Mastercard chargeback process’s specific rules for each reason code category. For authorization issues, for example, this means proving that proper authorization was obtained. For fraud claims, it means demonstrating the cardholder participated in or benefited from the transaction. We’ll get into more specific evidence requirements in our article about how to respond to Mastercard chargebacks.

Mastercard allows you 45 days from the date the chargeback is filed to submit a second presentment. This includes the filing date itself as “Day 1.” But, keep in mind that your acquirer needs time to review and transmit the claim to you, then to review and submit your response. So, you’ll probably have a much shorter time frame in which to actually work.

Mastercard also limits second presentment evidence to 18 pages maximum and 10MB total file size. Exceeding these limits may result in automatic rejection or additional fees. Evidence must be compiled into a rebuttal package and sent to your acquirer (typically uploaded to a dedicated chargeback management interface).

Pre-arbitration occurs when the issuer rejects your second presentment. The issuer remains convinced the cardholder’s claim is valid and the chargeback should stand. So, they submit a pre-arbitration response (sometimes colloquially called a “second chargeback”).

Issuers can file a pre-arbitration within 45 days of the date the second presentment was submitted.

The stakes are high here; pre-arbitration signals the issuer is prepared to escalate to arbitration, where Mastercard steps in to make a final ruling, and the losing party pays $500 in fees. You have to make a consequential choice. You can do one of two things:

• Accept Liability: Pay the chargeback amount, plus an additional pre-arbitration fee, and end the case.
• Decline Pre-Arbitration: Force the issuer to either reverse the chargeback or proceed to arbitration.

If the merchant declines pre-arbitration, the issuer must decide within 10 days whether to: reverse the chargeback (merchant wins), or file for arbitration (case proceeds to Mastercard's final ruling).

The arbitration stage of the Mastercard chargeback process is rare; fewer than 1% of chargebacks make it this far. The primary reason is cost: the losing party pays $500 in arbitration fees. Merchants who recognize they’re likely to lose can concede before Mastercard makes a ruling, reducing the fee to $300; still painful, but better than $500. These fees probably make arbitration an irrational option for all but the most high-value transactions.

At arbitration, Mastercard generally expects the same evidence already submitted. New evidence can sometimes be introduced if it wasn't available during second presentment, but this is case-specific. And, the issuer may also present additional evidence from the cardholder refuting your new claims, too.

Mastercard’s Dispute Resolution Management (DRM) team reviews the complete case file, including all evidence from both parties and the procedural history. They evaluate whether both parties followed Mastercard rules, whether the evidence supports the claims, and which party's position aligns with network regulations.

DRM rulings focus heavily on procedural compliance. Technical violations like late submissions, improper evidence format, or missing required documentation can result in an automatic loss regardless of the merits of the case.
