What is a chargeback?
Understand what a chargeback is, why customers file them, how the process works, and what it means for your organization as the merchant.
Short answer
A chargeback happens when a cardholder disputes a card payment and their bank reverses the transaction, pulling the money back from the merchant and returning it to the customer.
Chargebacks are part of card-network rules that protect customers from unauthorized or problem transactions, but they can create real financial and operational impact for your organization.
Common reasons for chargebacks
Customers typically file a chargeback when they believe there is a problem with a card transaction. Common reasons include:
-
Fraud or unauthorized use
The cardholder does not recognize the charge or claims they did not authorize it (for example, stolen card or card number). -
Did not receive the product or service
The customer paid but believes what they paid for never happened or was never delivered. -
Product or service not as described
What the customer received is defective, incomplete, or meaningfully different from what was advertised or agreed to. -
Billing errors
The merchant charged the customer twice, charged the wrong amount, or processed a payment the customer thought had been canceled or refunded.
Chargebacks are different from refunds: a refund is initiated by the merchant, while a chargeback is initiated by the customer through their bank.
How the chargeback process typically works
The exact details can vary by card network and processor, but most chargebacks follow the same general flow.
Customer disputes the transaction
The cardholder contacts their bank or card issuer to say there is a problem with a specific charge. The bank may ask for details such as dates, amounts, and why they are disputing it.
Bank reverses the charge temporarily
The bank opens a dispute and temporarily pulls the money back from the merchant, crediting the customer for the amount in question while the case is reviewed.
Merchant can submit evidence
The processor notifies the merchant of the dispute and gives the merchant a window of time to respond. During this time the merchant may submit supporting documents such as receipts, signed contracts, attendance records, or proof of delivery.
Card network or bank makes a decision
After reviewing the customer’s claim and the merchant’s evidence, the card network or bank decides whether the chargeback is valid and who keeps the funds.
If the decision goes in the merchant’s favor, the funds are usually returned to the merchant and the customer’s temporary credit can be reversed.
What happens if the merchant loses
When the chargeback is decided in the customer’s favor, the impact on the merchant typically includes:
-
Permanent loss of the transaction amount
The money from the original charge does not return to the merchant and stays with the customer. -
Chargeback fees
The merchant is often charged a separate fee by their processor for handling the dispute, on top of losing the original payment. -
Higher processing risk and costs
A pattern of frequent chargebacks can flag the merchant as higher risk, which may lead to higher processing fees, additional holds or reserves, or stricter monitoring. -
Risk to ability to accept cards
If chargeback rates stay high, processors or card networks may limit or even terminate the merchant’s ability to process card payments.
Chargebacks are intended as a consumer-protection tool, but they can also be misused or filed in situations that feel unfair to merchants. This page is general information only and not legal or financial advice; work with your payment processor and advisors for policies that fit your organization.
