A chargeback is a forced reversal of a credit or debit card transaction initiated by the cardholder’s bank.
Instead of contacting the merchant for a refund, the customer disputes the transaction with their issuing bank.
The bank:
A chargeback is not simply a refund.
It is a regulated compliance process governed by card network rules.
The issuing bank accepts the dispute and assigns a reason code.
The transaction amount plus a chargeback fee is debited from the merchant account.
The acquiring bank or processor notifies the merchant.
The merchant gathers and submits evidence proving the transaction was valid.
The issuing bank evaluates the evidence and makes a decision.
If either party challenges the decision, the case may move to:
Most disputes are resolved at the issuing bank level.
This is widely misunderstood.
The issuing bank decides most chargebacks.
Visa, Mastercard, Discover, and American Express create the rules — but they do not review every case.
Only if the dispute escalates to arbitration does the card network make a final ruling.
That’s why documentation and compliance matter more than merchants realize.
When you receive a chargeback notice:
Identify the reason code Review transaction details Collect proof of authorization Provide delivery confirmation (if applicable) Include refund/cancellation policy Submit within the deadline (typically 7–21 days)
Miss the deadline and you automatically lose.
Chargebacks are complicated because:
For e-commerce merchants, compliance begins long before the dispute happens.
Amex refers to disputes as “Inquiries” or “Chargebacks.”
Common categories:
Amex often has shorter response windows.
Chargebacks cost more than the transaction amount:
High dispute ratios can place merchants into monitoring programs.
VAMP is Visa’s system for monitoring:
If your ratio exceeds Visa’s thresholds, you may enter a monitoring program.
That can result in:
VAMP is enforced at the network level — not just by your processor.
RDR is a Visa program that allows merchants to automatically refund transactions before they become formal chargebacks.
When a cardholder contacts their bank:
RDR is especially important for:
Prevention is far less expensive than representment.
If you process large online volume:
Using RDR and alert tools helps merchants:
Refund low-dollar disputes automatically Prevent VAMP violations Lower chargeback ratios Protect long-term account stability
Ignoring alerts can quickly push a merchant into a monitoring program.
