Chargeback Rules: The Complete Merchant Guide

Chargeback rules define when a card payment can be disputed, what evidence supports a response, and how the case can progress. Card networks establish their dispute frameworks, while issuers, acquirers, and payment processors carry out different parts of the process.

Who Sets and Applies Chargeback Rules?

Start with the relevant card network’s rules. The issuer assesses the cardholder’s dispute and the evidence received through the network process. Your acquirer or payment service provider communicates the case and the requirements for your response.

A useful internal case record keeps these roles distinct. Write down the network, processor, reason code, case stage, submission deadline, and assigned owner. Avoid treating a processor notification as a general statement about every card network.

The Visa Core Rules and Visa Product and Service Rules and Mastercard Chargeback Guide are primary references. Use the applicable dispute condition and current edition, not a generic timeline copied from another case.

Find the Rules for Your Card Network

Choose the network first, then use the case instructions to confirm your response channel and due date. The network rule and the provider’s merchant deadline serve different purposes.

For code lookup, use the reason-code directory. For the different clocks, use chargeback time limits. For an unresolved escalation, use the arbitration guide; reconcile the result with chargeback accounting.

Choose Evidence by the Disputed Issue

Your first task is to identify what the cardholder is contesting. Use the chargeback reason code as the starting point, then read the actual allegation.

Do not discard delivery records simply because the case concerns fraud. Their relevance depends on the applicable condition and other evidence. Equally, proof of delivery does not automatically answer every allegation. If you suspect friendly fraud, explain the records rather than accusing the customer without support.

Create an attachment index with a short statement of what each record shows. For example, identify whether a customer message confirms receipt, requests cancellation, or acknowledges a refund. Keep those claims precise so the reviewer does not need to infer the connection.

Separate Filing Limits From Your Response Deadline

A cardholder filing period, a network exchange period, and your merchant deadline are different clocks. Processor response guidance illustrates why: Stripe describes a response window usually ranging from 7 to 21 days. Follow the deadline assigned to your actual case.

Visa’s rules include 120-day filing periods for specified conditions and a 540-day outer limit in certain extended scenarios. The 540-day provision is not a blanket cap on every stage from chargeback through arbitration. Check the relevant condition’s timing table.

Set your own review cutoff before the processor deadline. Assign responsibility for missing documents and confirm that the final packet was submitted. A saved draft is not a submission receipt.

Understand Monitoring Separately From Representment

Winning a dispute and preventing a dispute are different outcomes. A recovery report should not be used as proof that a monitoring ratio has fallen. Reconcile program data with your acquirer and check which exclusions apply.

Visa’s VAMP fact sheet defines its count-based ratio using fraud reports plus disputes divided by settled transactions, with specified exclusions. For AP, Canada, the EU, and the U.S., it states an excessive-merchant ratio threshold of at least 1.5% from April 1, 2026, alongside a monthly count of at least 1,500 fraud reports and disputes, subject to its acquirer-status conditions. Other regions differ.

For planning, ask your acquirer to confirm the applicable region, counts, exclusions, reporting period, and remediation requirements. The VAMP guide explains the program context; keep Mastercard monitoring as a separate review rather than treating it as the same metric.

Use chargeback alerts where supported as an early-resolution workflow. Do not assume ordinary evidence submission removes a filed dispute from monitoring calculations.

Build a Repeatable Response Checklist

This process supports chargeback representment without assuming procedural compliance alone guarantees a win. Evidence, eligibility, and the decision maker’s assessment still matter.

Assess Escalation With Your Acquirer

If a case progresses after your response, confirm the next stage and permitted action. The chargeback process can involve further exchanges and network escalation, depending on the framework.

Before proceeding, request the applicable fees, deadline, evidence requirements, and possible financial exposure. Compare those with the disputed amount and the strength of the specific case. Do not treat escalation as a routine extension of the first response.

Sources and scope

Source notes updated: October 11, 2026. Card-payment disputes. Identify the network, region, reason and case stage before applying a rule. A cardholder filing window is different from a merchant submission deadline; use the due date and timezone on the merchant case notice.

• Mastercard: rules and chargeback documents
• Stripe: responding to card disputes

For a live case, retain the governing document’s edition or effective date, the relevant provision, and the provider notice.

Frequently Asked Questions

Do Merchants Always Have 30 or 45 Days to Respond?

Merchant response deadlines vary by processor, network, and case stage. Use the deadline in the dispute notification rather than assuming a universal 30-day or 45-day window.

What Is the 540-Day Chargeback Rule?

The 540-day provision is an outer filing limit for specified Visa dispute circumstances. It is not a universal deadline for the entire dispute lifecycle.

Does Winning a Chargeback Remove It From Monitoring?

A chargeback win does not automatically remove the filing from a monitoring metric. Check the program’s calculation and exclusions with your acquirer.

Can Delivery Evidence Help With a Fraud Dispute?

Delivery evidence can be relevant depending on the dispute condition and the supporting records. It should not be universally excluded or treated as a guaranteed defense.

Where Should Merchants Check Current Rules?

Merchants should consult the applicable network’s primary rules and their processor or acquirer’s instructions for the specific case.

Keep Your Dispute Process Current

Maintain one owner for rule updates and one source of truth for case deadlines. Review changes when your acquirer notifies you, then update the evidence checklist your team actually uses.
