What Is a Chargeback and How Do You Fight One Successfully?

A chargeback is one of the most frustrating things that can happen to a merchant. Unlike a refund — where a customer asks you to return their money — a chargeback bypasses you entirely. The customer calls their bank, the bank disputes the charge on their behalf, and funds are pulled from your account while the dispute is investigated. Here's how to understand them, fight them, and reduce how often they happen.

What Triggers a Chargeback

There are four primary reasons customers initiate chargebacks:

Item not received (INR): The customer claims they never got what they paid for. This is common for e-commerce sellers, especially with high-value items or international shipments where tracking is unclear.

Item not as described (INAD): The product or service delivered didn't match what was advertised or sold. This is common in marketplaces, custom orders, and subscription businesses where customers feel misled.

Unauthorized transaction: The customer claims they didn't make the purchase — either their card was stolen, or they genuinely don't recognize the charge (also called "friendly fraud" when the claim is false).

Credit not processed: The customer returned the item or canceled the service but never received the refund they expected.

The Chargeback Timeline

Understanding the timeline is critical because you have narrow windows to respond:

1. Purchase made: Day 0
2. Customer disputes with bank: Can happen up to 60-120 days after the purchase date (Visa allows 120 days for most dispute types)
3. Bank contacts the card network: Card network notifies your processor
4. Merchant notified: You receive a chargeback notice from your processor — typically 7-14 days after the dispute was initiated
5. Response window: You usually have 7-20 days to respond with evidence (varies by processor and card network)
6. Resolution: The bank reviews both sides and makes a ruling, typically within 30-45 days

The most important thing: missing your response deadline means an automatic loss. Set up alerts or check your processor dashboard regularly.

How to Fight a Chargeback: Building Your Evidence Packet

Your job in a chargeback dispute is to prove the transaction was legitimate and fulfilled. Here's what to gather:

For all disputes:

• Order confirmation email with timestamp
• Customer billing and shipping information submitted at checkout
• IP address of the order (for online transactions)
• Any customer communications (emails, chat logs, support tickets)
• Your terms of service and refund policy (confirm the customer agreed to them at checkout)

For "item not received" disputes:

• Shipping tracking information showing delivery confirmation
• For orders over ~$75, carrier confirmation of delivery (signature required if possible)
• Proof of delivery to the billing address (some card networks require this for high-value disputes)

For "item not as described" disputes:

• Product description or listing at the time of purchase
• Photos of the item as shipped
• Any customer communications about the product before the dispute
• Evidence the product matched the description

For "unauthorized transaction" disputes:

• Evidence the billing and shipping address match (reduces fraud probability)
• Device fingerprint and IP address matching the cardholder''s location
• Prior purchase history from the same card
• Signed delivery receipt if applicable

When You'll Lose (And Shouldn't Fight)

Not every chargeback is worth fighting. You'll almost certainly lose if:

• There's no delivery tracking or proof of fulfillment
• The transaction was card-not-present with no AVS (address verification) match
• The product genuinely wasn't as described or was defective
• Your customer service failed and the chargeback was a last resort

If the customer is clearly right, process the refund immediately rather than fighting — a lost chargeback costs more than a refund (you lose both the funds and the chargeback fee).

Chargeback Ratio Thresholds

Card networks monitor your chargeback ratio (chargebacks ÷ total transactions) monthly. Thresholds:

• Visa Early Warning: 0.65% ratio
• Visa Standard Monitoring: 0.9% ratio
• Mastercard Excessive: 1.0% ratio

Exceeding these thresholds triggers monitoring programs, increased fees, and ultimately potential account termination. Most processors have their own lower thresholds (0.5-0.65%) and may terminate your account before you hit the card network level.

Keep your chargeback ratio below 0.5% to stay safe and avoid the scrutiny that comes with monitoring programs.
