Dispute

Disputes and chargebacks are closely related concepts: a chargeback is the financial reversal that may result from a dispute, while a dispute is the full process — from initial cardholder claim through potential arbitration — that determines whether a reversal is warranted. For practical purposes, the terms are often used interchangeably, though major schemes have moved toward “dispute” as the preferred terminology.

Dispute Lifecycle

The dispute lifecycle under Visa’s Dispute Resolution (VDR) process and Mastercard’s Dispute Resolution process follows a defined sequence:

1. Cardholder claim: The cardholder contacts their issuing bank to dispute a charge. Common reasons include:

• Unauthorized transaction (fraud)
• Item not received (INR)
• Item significantly not as described (SNAD)
• Duplicate charge
• Credit not processed

2. Issuer investigation: The issuer reviews the claim. If deemed valid, the issuer initiates the dispute by debiting the transaction amount from the acquirer via the card network.

3. Merchant notification: The acquirer notifies the merchant of the dispute and provides documentation requirements and response deadlines. Response windows are typically 20–30 days depending on the scheme and dispute reason code.

4. Merchant response (Representment): The merchant (via the acquirer) may challenge the dispute by submitting evidence: proof of delivery, signed authorization, customer communications, terms and conditions acceptance.

5. Issuer review: The issuer reviews the merchant’s evidence. If the evidence is compelling, the dispute is resolved in the merchant’s favor and funds are returned.

6. Pre-arbitration: If the issuer rejects the merchant’s evidence, some schemes provide a pre-arbitration stage where the acquirer may submit additional evidence or accept the chargeback.

7. Arbitration: Either party can escalate to card network arbitration. The network makes a final ruling. The losing party pays the arbitration fee (typically $250–$500) in addition to the transaction amount.

Dispute Reason Codes

Card networks use reason codes to classify disputes. Visa’s reason codes (VDR system) and Mastercard’s reason codes organize disputes into categories:

• Fraud: Unauthorized card use (the most common and highest-risk category for CNP merchants)
• Authorization: Transaction processed without valid authorization
• Processing errors: Duplicate processing, incorrect amount
• Consumer disputes: Not received, not as described

Reason codes drive the required evidence and the applicable scheme rules. Submitting evidence relevant to the wrong reason code is a common merchant error that results in failed representments.

Dispute Rate Monitoring

Card networks monitor merchant dispute rates and apply escalating consequences for merchants with elevated rates:

• Visa Dispute Monitoring Program (VDMP): Merchants exceeding 0.9% dispute rate or 100 disputes/month are enrolled in early warning; 1.8% or 1,000 disputes triggers standard monitoring with potential fines
• Mastercard Excessive Chargeback Program: Similar thresholds apply

Acquirers are jointly liable for merchants under monitoring programs and typically pass costs and fines to the merchant, or in extreme cases terminate the relationship.

Southeast Asia Context

Dispute rates in SEA e-commerce tend to run higher than in mature Western markets, driven by:

• Higher card fraud rates, particularly for cross-border CNP transactions
• Lower consumer familiarity with the dispute process in some markets, leading to delays in legitimate fraud reporting
• Subscription and trial billing disputes from less clearly communicated terms
• Platform and marketplace disputes where the end merchant’s identity is unclear to the cardholder

Payment facilitators and marketplaces in SEA should implement pre-dispute resolution mechanisms — customer service contacts, easy refund processes — to resolve merchant-customer conflicts before they escalate to formal card disputes, as dispute rates are often preventable.
