How Does a Chargeback Work on a Credit Card? [2026]
A chargeback is when a bank reverses a credit card transaction after a cardholder disputes it. The merchant loses the sale amount, plus processing fees, plus the chargeback fee — and the reversal happens before any investigation. Understanding exactly how the process works helps merchants respond faster, submit stronger evidence, and win more disputes.

What is a credit card chargeback?
A chargeback is a transaction reversal initiated by the cardholder's bank — not by the cardholder, and not by the merchant. When a cardholder disputes a credit card transaction, their bank reviews the complaint and, if it decides to proceed, formally reverses the transaction. The money is pulled back from the merchant's account and returned to the cardholder.
This reversal happens before the merchant has a chance to respond. The bank issues a provisional credit to the cardholder immediately and then notifies the merchant. At that point, the merchant can accept the chargeback (keep the money gone) or contest it through a process called representment.
Beyond the transaction amount, chargebacks carry additional costs that add up quickly:
- •Chargeback fee from your processor: typically $15-20 per dispute, charged regardless of outcome
- •Cost of goods or services already delivered but not recovered
- •Staff time to research and respond to the dispute
- •Ratio impact: each chargeback counts against your dispute ratio, which triggers monitoring programs if it crosses network thresholds
- •Average total cost per dispute in 2026: approximately $82, accounting for fees, time, and administrative overhead
The chargeback mechanism was created by the Fair Credit Billing Act (1974) to protect consumers from fraudulent merchants. Decades later, it is frequently used in the opposite direction — against legitimate merchants by consumers who claim chargebacks for purchases they actually authorized and received. This phenomenon, called friendly fraud, accounts for an estimated 40-80% of eCommerce chargebacks.
The 5 parties in a chargeback
Every chargeback involves five distinct parties with different roles and different interests:
Cardholder
The customer who made the purchase and is disputing it. They contact their bank to initiate the dispute process. The cardholder does not need to contact the merchant before filing — and 75% do not.
Issuing bank
The cardholder's bank (e.g. Chase, Bank of America, Barclays). The issuing bank reviews the cardholder's complaint, decides whether to initiate a formal chargeback, issues provisional credit to the cardholder, notifies the acquiring bank, and ultimately decides the outcome after reviewing the merchant's response.
Card network
Visa, Mastercard, American Express, or Discover. The card network sets the rules — which dispute categories exist, what evidence is required for each, what the timelines are, and what happens if the issuing bank and merchant cannot agree. The network also runs merchant monitoring programs and arbitration.
Acquiring bank (processor)
The merchant's bank or payment processor (e.g. Stripe, PayPal, Adyen, Worldpay). The acquiring bank receives the chargeback notification from the issuing bank through the card network, debits the merchant's account for the dispute amount, and forwards the notification to the merchant. The acquirer may also provide dispute management tools.
Merchant
The business that processed the original transaction. The merchant receives the chargeback notification from their processor, has a defined window to respond, and must submit evidence and a rebuttal letter if they wish to contest the dispute. The merchant cannot prevent the chargeback from being filed but can respond to it.
How money flows in a chargeback
At the time of the original transaction: cardholder pays issuing bank → issuing bank sends funds through network → acquiring bank/processor → merchant account.
When a chargeback is initiated: the reversal flows in the opposite direction. The acquiring bank debits the merchant account → sends funds back through the network to the issuing bank → issuing bank credits the cardholder. The merchant account is debited before any review of the merchant's evidence.
Step-by-step: the chargeback process
The chargeback process follows a defined sequence. Here is exactly what happens at each stage:
Cardholder contacts their bank
The cardholder calls, messages, or logs into their bank app to report a problem with a transaction. They select a dispute reason — fraud, goods not received, not as described, duplicate charge, etc. The bank records the complaint and the cardholder's account of events.
Issuing bank assigns a reason code and initiates the chargeback
The bank reviews the complaint and assigns a card network reason code (e.g. Visa 10.4 for fraud, Visa 13.1 for goods not received). It issues a provisional credit to the cardholder and sends the chargeback through the network to the acquiring bank. This is the formal initiation of the chargeback.
Acquiring bank notifies the merchant
The acquiring bank receives the chargeback, debits the merchant's account for the dispute amount plus the chargeback fee, and sends the merchant a notification. This notification includes the reason code, the dispute amount, and the response deadline.
Merchant has 20-45 days to respond
The response window depends on the card network: Visa gives 30 days, Mastercard 45 days, Amex 20 days, Discover 30 days. The merchant must submit their response — evidence plus rebuttal letter — within this window. Missing the deadline means the chargeback is upheld automatically.
Merchant submits evidence and rebuttal letter (representment)
If the merchant decides to contest, they submit a formal representment: a package of evidence matching the specific reason code, plus a written rebuttal letter explaining why the chargeback is invalid. This is submitted through the processor to the issuing bank.
Issuing bank reviews and decides
The issuing bank reviews the representment. If they find in favor of the merchant, the chargeback is reversed and the funds are returned to the merchant account. If they maintain the chargeback, the merchant loses the funds.
Pre-arbitration and arbitration (if escalated)
If the merchant disagrees with the issuing bank's decision after representment, either party can escalate to pre-arbitration — a second round of documentation review. If that does not resolve the dispute, the case can go to full network arbitration, where Visa or Mastercard issues a binding final decision. The losing party pays the arbitration fee.
Why 75% of customers skip the merchant
Research consistently shows that approximately 75% of consumers go directly to their bank rather than contacting the merchant when they have a problem with a transaction. This is one of the most operationally significant data points in chargeback management, and understanding why it happens points toward how to partially address it.
The primary reasons consumers bypass merchants:
Banks are perceived as easier to deal with
Most banks offer 24/7 dispute filing through apps or phone. The customer pushes a button and the bank handles it. Many merchants make it harder to reach customer service — buried contact pages, limited hours, slow response times.
Customers assume the bank will side with them
This assumption is largely correct. Banks give provisional credit immediately and the burden of proof falls on the merchant. Cardholders have learned that the bank dispute process is efficient and usually favorable.
They do not know merchant contact is an option or obligation
Many cardholders are not aware that card network rules generally expect them to attempt resolution with the merchant first. They do not know this is a step in the process — they just know their bank has a dispute button.
Some want to avoid confrontation
Filing a dispute through a bank feels less confrontational than calling a merchant to say there is a problem. The bank acts as an intermediary.
The impact: 44% of disputes could be resolved if the merchant contacts the customer first. 31% are resolved when the merchant issues a refund proactively. Only 25% still escalate to formal chargeback after merchant contact. In other words, most chargebacks from customers who do contact you never become formal chargebacks.
The practical implication: make it as easy as possible for customers to find and contact you. Put your phone number or live chat link in the billing descriptor, the order confirmation email, and the shipping notification. Every customer who contacts you instead of the bank is a prevented chargeback.
What triggers a chargeback vs an inquiry (pre-dispute)
Many merchants do not realize that there are two distinct stages in the dispute process — and that acting at the earlier stage can prevent the formal chargeback entirely.
| Stage | What has happened | Merchant action available | Counts against ratio? |
|---|---|---|---|
| Inquiry / Pre-dispute | Bank has asked merchant for information; transaction not yet reversed | Provide information or issue refund — dispute can be closed here | No |
| Formal chargeback | Bank has reversed the transaction; provisional credit issued to cardholder | Respond with evidence + rebuttal letter within network deadline | Yes |
| Representment | Merchant has contested; issuing bank is reviewing | No further action until decision issued | Yes (already counted) |
| Pre-arbitration | Bank maintained chargeback after representment; merchant is challenging again | Submit additional documentation | Yes (already counted) |
| Arbitration | Card network is acting as final arbiter | Submit full case record; outcome is binding | Yes (already counted) |
The key insight: responding at the inquiry stage — before the formal chargeback is issued — is the best possible outcome. If you issue a refund at the inquiry stage, the dispute closes without a formal chargeback, meaning it does not count against your chargeback ratio and you avoid the fee. Many processors (Stripe, PayPal, Shopify) surface inquiry notifications in their dashboards and allow direct response.
What merchants can do — and cannot do
The chargeback system is heavily weighted toward cardholders. Understanding what merchants can and cannot do prevents you from wasting effort on approaches that will not work — and from crossing legal lines that create additional liability.
What merchants CAN do
- ✓Respond to every chargeback with evidence and a rebuttal letter through the representment process
- ✓Refund the customer proactively before or immediately after a dispute to close it at the pre-chargeback stage
- ✓Request more information from the customer to clarify a dispute before it escalates
- ✓Use Visa Compelling Evidence 3.0 (CE 3.0) to demonstrate a pattern of legitimate transactions for eligible fraud disputes
- ✓Escalate to pre-arbitration and arbitration if you disagree with the issuing bank's decision after representment
- ✓File a case with the merchant's acquiring bank if you believe the issuing bank made an error
What merchants CANNOT do
- ✗Prevent a customer from filing a chargeback — this is a legal right under the Fair Credit Billing Act
- ✗Require customers to contact you before disputing (you can ask, but cannot enforce this as a condition of sale)
- ✗Include "no chargebacks" clauses in terms — these are unenforceable against FCBA and EFTA rights
- ✗Attempt to collect the disputed amount while the dispute is pending
- ✗Cancel a customer account or take adverse action because they filed a legitimate dispute
- ✗Ignore the chargeback — non-response means the chargeback is automatically upheld

How chargebacks differ from refunds
Many merchants treat chargebacks and refunds as equivalent — the money goes back to the customer in both cases. They are not equivalent. The differences matter significantly:
| Factor | Refund | Chargeback |
|---|---|---|
| Who initiates it | Merchant | Customer's bank |
| Extra fee | No (processor fee already paid) | Yes — $15-20 chargeback fee |
| Counts against chargeback ratio | No | Yes |
| Bank involvement | None | Issuing bank acts as judge |
| Time to process | 3-5 business days | 30-90 days to final resolution |
| Merchant can block it | Yes (merchant controls) | No (bank initiates) |
| Staff time required | Minimal | Significant (response building) |
The strategic implication: if a customer contacts you with a complaint that is legitimate — the product is genuinely not what they expected, or there was a shipping issue — issuing a refund immediately is almost always the right decision. It costs less than a chargeback (no extra fee), does not affect your ratio, and closes the interaction quickly.
Where merchants get the calculation wrong: they fight every complaint to "protect revenue," converting many resolvable disputes into chargebacks. A refund on a legitimate complaint protects ratio and avoids fees. Reserve your contestation energy for chargebacks filed in bad faith — where the customer has the product and is falsely claiming otherwise.
