Full Chargeback Dispute Resolution Process: Visa/Mastercard/JCB Practical Differences at a Glance

Some customers, even after receiving goods or using services, suddenly claim they 'don't recognize' the transaction after a period. Banks might even claw back funds directly and add extra fees. This is the chargeback that merchants dread the most.

Full Chargeback Dispute Resolution Process: Visa/Mastercard/JCB Practical Differences at a Glance

Some customers, even after receiving goods or using services, suddenly claim they 'don't recognize' the transaction after a period. Banks might even claw back funds directly and add extra fees. This is the chargeback that merchants dread the most.

A chargeback doesn't mean 'the customer is always right.' It's actually a dispute resolution mechanism established by card organizations (like Visa, Mastercard, JCB, etc.): the cardholder raises a dispute with their issuing bank, the acquiring bank then notifies the merchant to provide evidence, and ultimately, a decision is made based on rules and documentation. Crucially, the process has deadlines, format requirements, and varies at each stage, especially with notable practical differences between JCB and Visa/Mastercard.

The Chargeback Process: More Than Just a 'Refund'

A typical refund is initiated by the merchant and involves direct communication with the customer; a chargeback, however, involves the customer complaining to their bank, and the issuing bank processes it according to card organization rules. During this time, funds might be temporarily frozen, or even settled funds could be clawed back.

Furthermore, chargebacks usually incur additional fees (charged by the acquiring bank or service provider). Losing means 'refund plus fees,' and even winning might not be entirely without impact, as dispute ratios are monitored. A high ratio can trigger additional risk assessments, reserve requirements, or even increased processing fees.

When you receive a dispute notification, how should you categorize and handle it?

The first step shouldn't just be looking for transaction receipts. You should first determine the dispute category, as evidence needs to be prepared specifically for the reason code.

Common situations generally fall into three categories:

  • • Unauthorized transaction (fraud/unauthorized): Cardholder claims they never made the purchase
  • • Goods or service issues: Not received, not as described, quality dispute, cancellation policy dispute
  • • Procedural or authorization issues: Duplicate charge, authorization revoked, incorrect amount, refunded but not credited

The same receipt might be ineffective for 'not received' but crucial for 'duplicate charge.' Therefore, the earlier and more accurately you categorize, the more efficient your subsequent document preparation will be.

Visa / Mastercard / JCB: Practical Differences in Process

The basic process for all three card organizations is 'issuing bank raises dispute → acquiring bank notifies merchant → merchant submits evidence → decision based on rules,' but the detailed differences directly impact a merchant's response strategy.

Common Process Differences

Merchant Response Time (after notification)Approx. 20 to 45 days (depending on reason code and channel)Approx. 20 to 45 days (depending on reason code and channel)Submit defense documents within approx. 40 days

Escalation PathAfter appeal, can enter pre-arbitration, then arbitrationAfter appeal, can enter pre-arbitration, then arbitrationCommon process is RFI (Request for Information) → First chargeback (documents can be submitted) → Second chargeback (generally no new documents accepted) → Arbitration
Key Document StrategyAssemble 'compelling evidence' tailored to the reason code combinationSame as above, emphasis on 'compelling evidence'Try to gather all documents for the first submission, as it's usually not possible to add new ones in the second stage

If you operate both online and offline businesses, the differences will be even more pronounced. Visa/Mastercard still offers opportunities to dispute during pre-arbitration in later stages; JCB, however, is more like 'first round wins all,' where missing documents in the first round are often difficult to remedy later.

JCB's Practical Challenges

JCB's difficulty isn't about overly strict rules, but rather its pace and submission mechanism: once it enters the second chargeback stage, new documents are generally not accepted, and merchants can only escalate to arbitration through their acquirer and JCB.

Therefore, winning a JCB dispute usually relies on two points:

  1. The initial submission of documents must be clear and complete, allowing the cardholder to 'recognize' the transaction and directly refute the reason code.
  2. An internal process must be in place to 'collect evidence immediately upon notification,' avoiding rushed preparation close to deadlines.

‍How to Make Evidence 'Relevant'? Quality Over Quantity

Banks and card organizations aren't interested in how many documents a merchant has, but rather whether there's a direct response to the cardholder's accusation. Think of it as a 'cross-reference table': each accusation requires a precisely corresponding piece of evidence.

Common Types of Effective Evidence

  • • Proof of transaction: Receipts, signed slips, order confirmation pages, authorization records
  • • Proof of delivery/usage: Shipping delivery confirmation, tracking numbers, in-store pickup records, service usage records (e.g., class attendance, clinic visit, event entry)
  • • Customer communication: Emails, WhatsApp/SMS conversations, customer service tickets, ideally showing customer confirmation of solution or receipt of goods
  • • Policy disclosure: Refund/cancellation/exchange terms, product description pages, pricing details (must prove customer could see these at time of purchase)
  • • Anti-fraud data (common for online stores): 3DS authentication, AVS/CVV results, IP/device data, login records (depending on availability)

Note: Visa rules generally discourage merchants from making 'showing ID' a condition for transactions. Therefore, rather than relying on 'checking ID,' a more practical approach is to improve the payment process, such as 3DS, signature confirmation, and traceable proof of delivery.

Chargeback Timeline and Key Milestones

A chargeback is a document-based race against time. Generally, after the issuing bank notifies the acquiring bank, the merchant needs to respond within a specified number of days (Visa/Mastercard approx. 20 to 45 days, JCB approx. 40 days), and the entire dispute cycle can last up to 120 days or even longer.

Recommended Internal Processing Steps

  1. Open a case immediately upon notification: Immediately lock down transaction, order, shipping, and customer communications to avoid data loss or colleagues' fading memories.
  2. First, determine the reason code direction: Is it fraud or 'not received/not as described'? You need to choose the right evidence path from the start.
  3. Create a one-page summary: Clearly list timestamps, delivery points, customer confirmation points, with attachments corresponding one by one.
  4. Submit early, avoid last-minute: Submitting documents at the last minute means even minor formatting issues could lead to lost opportunities.
  5. Budget for escalation costs: If entering pre-arbitration or arbitration, additional fees and time costs may be involved; assess whether it's worth continuing.

This approach may seem administrative, but it can indeed save many cases where 'evidence exists but wasn't submitted in time or correctly.'

Cross-Border Transaction Dispute Risks and Response

The problem with cross-border chargebacks isn't just language barriers, but also information asymmetry.

Common Cross-Border Dispute Pitfalls

  • • Exchange rates and currencies: The amount and currency on the cardholder's statement might not match the settlement amount in the merchant's backend. When dealing with returns or chargebacks, exchange rate fluctuations can cause discrepancies in 'the same transaction,' making it easier for cardholders to misunderstand it as a duplicate charge or erroneous fee. When submitting evidence, clearly indicate the original transaction currency, settlement currency, conversion time, and if necessary, attach screenshots of the transaction page or payment confirmation page.
  • • Policy disclosure: If cancellation terms, shipping fees, and delivery times are not clear enough, cross-border customers are more likely to dispute based on 'not as described.' Even if you ultimately win, it wastes manpower and cash flow.

Centralized Dispute Management and its Impact on Operations

Many merchants' pain point isn't that they 'don't know how to handle chargebacks,' but rather that they have physical stores, online stores, delivery platforms, and phone orders, with diverse payment methods and scattered data. When a dispute occurs, they start scrambling for receipts, conversations, and shipping records, having already lost the advantage of time.

Wonder offers comprehensive fintech tools for Hong Kong and Asia-Pacific merchants, covering online and offline payments, settlements, disbursements, business expense management, and data analytics. For chargeback management, its practical benefit lies in centralizing the display of transaction and dispute statuses from various card organizations, allowing merchants to process them at a consistent pace without needing to track through different channels.

Using Wonder reports as an example, merchants can see dispute-related fields in transaction analysis, such as 'Total Hold & Dispute' and 'Total Chargeback Amount,' as well as statuses like 'Risk Hold,' which indicates that funds have been temporarily clawed back for review due to risk or dispute after transaction settlement. When a dispute is canceled or resolved, funds might be released with statuses like 'Cancelled Dispute.'

These terms on the surface are just report fields, but in reality, they reflect operational logic: merchants are not just 'striving to win,' but also managing cash flow and human resource processes.

How to Effectively Reduce Chargebacks?

To lower chargebacks, you can't just rely on occasionally 'winning cases.' Instead, you need to transform high-risk scenarios into processes that are demonstrable, traceable, and allow for quick responses.

Three Levels of Chargeback Prevention

  1. Pre-payment: Clearly display prices, currencies, shipping costs, delivery times, and cancellation terms to avoid disputes due to unclear information.
  2. During transaction: Retain authorization and delivery proof as much as possible; for online transactions, consider adding 3DS authentication when appropriate.
  3. Post-transaction: Customer service responses need to be recorded, and refund processing needs a reference number to avoid 'refunded but customer claims not received' scenarios.

If you have multiple payment methods, being able to process transactions, reconcile, and analyze trends on a single platform will make daily management more efficient. Wonder offers up to cards, mobile wallets, QR payments and more and focuses on quick 7-minute account setup for immediate payment acceptance; coupled with real-time data analysis and automatic reconciliation, it makes it easier for merchants managing store cash flow, online transactions, and dispute ratios simultaneously to establish a consistent rhythm.

If you're already facing a dispute, how to quickly help yourself?

You don't immediately need to consider 'fighting all the way to arbitration.' Many disputes actually stem from insufficient information, customers not recognizing the merchant's name, or colleagues delaying refund processing.

Quick Self-Help Steps

  1. Optimize transaction description: Clearly list the merchant name (Descriptor), branch name, phone number, order number, service date, and other information. JCB sometimes has an RFI (Request for Information) stage, whose purpose is to allow merchants to provide additional information to help cardholders recognize the transaction. Doing this well can resolve issues before they even turn into a chargeback.
  2. Assess whether to fight: If the evidence is weak, fighting aggressively will only increase fees and waste human resources; if the evidence is complete, especially with proof of delivery or usage, then submit it all at once within the deadline.

The more systematized your processing, the more chargebacks can become a controllable cost, rather than always turning into unexpected incidents.
