A chargeback is a forced payment reversal initiated by a cardholder through their issuing bank. If you do not respond — or respond incorrectly — you lose the funds permanently, and the merchandise or service is gone too.

Why Chargebacks Happen

Friendly fraud: Customer received goods but denies the purchase
Unrecognized transaction: Customer doesn't recognize the merchant name
Item not received: Customer claims goods were not delivered
True fraud: Card was actually stolen and used fraudulently
Processing error: Amount charged was incorrect

Response Timelines

Visa typically allows 30 days. Mastercard approximately 45 days. American Express can have shorter windows. Missing the deadline results in automatic loss — no exceptions.

What Evidence Actually Wins Chargebacks

For Card-Present Transactions

Signed transaction receipt (EMV chip read, not swipe)
Signed sales receipt or order form
Delivery confirmation or pickup record

For Card-Not-Present / Online Transactions

Proof of delivery with tracking number and confirmation
Customer's IP address at time of order
Email correspondence with the customer
3D Secure authentication record — shifts liability to the bank

The Representment Process

Step 1: Review the chargeback reason code. Step 2: Gather relevant documentation matching the reason code. Step 3: Write a factual rebuttal letter. Step 4: Submit before the deadline.

Chargeback Prevention

Use EMV chip terminals for liability protection on counterfeit fraud
Use 3D Secure for online transactions
Ensure your business name appears clearly on cardholder statements
Send order confirmation emails and shipping notifications
Respond quickly to customer service inquiries

Frequently Asked Questions

How long do I have to respond to a chargeback?

Visa typically allows 30 days, Mastercard approximately 45 days, and American Express can have shorter windows. The deadline runs from the date your processor notifies you. Missing the deadline results in an automatic loss.

What is the best evidence to fight a chargeback?

The best evidence directly contradicts the specific reason code. For 'item not received,' a signed delivery confirmation is powerful. EMV chip transaction records are very strong evidence for in-person disputes.
