Short answer
A chargeback starts when a cardholder disputes a charge with their card issuer. The issuer sends the transaction back through the card network, and your acquirer debits your account and asks for your side. You either accept the loss or send evidence. If the issuer still disagrees, the case can move to pre-arbitration and then to arbitration, where the network decides.
How does a chargeback work? A cardholder tells their card issuer that a charge is wrong, the issuer sends the transaction back through the card network to your merchant bank (the acquirer), and the acquirer takes the money out of your account and asks for your side of the story. Visa describes a dispute as the reversal of a transaction's value by the issuer to the acquirer, and usually by the acquirer back to the merchant. Everything after that is an exchange of evidence on a deadline, and it can drag on for months.
This guide follows one chargeback from start to finish: the steps, the deadlines, the costs, the reason codes, the cardholder's rights under Regulation Z, and when to fight. Rules are current as of October 2026. If you'd rather stop chargebacks before they're filed, our companion guide on how to prevent chargebacks covers that side. For the tools and dedicated rep we provide, see how Clearo helps with chargebacks.
Who is involved in a chargeback?
Five parties touch every chargeback. Knowing who holds the money at each moment explains most of what happens next.
| Party | Who they are | Their part in a chargeback |
|---|---|---|
| Cardholder | Your customer | Starts the dispute with their bank |
| Issuer | The bank that issued the card | Checks the claim against the network rules and files the chargeback |
| Card network | Visa, Mastercard, and the other brands | Writes the dispute rules and decides cases that reach arbitration |
| Acquirer | Your merchant bank, usually reached through your processor | Debits your account, sends you the notice, and submits your response |
| Merchant | You | Accepts the chargeback or answers it with evidence |
Visa's rulebook says "dispute" where Mastercard's says "chargeback," but the mechanics line up. You'll rarely talk to the issuer yourself. Your evidence goes to your acquiring bank, which passes it to the issuing bank, and the answer comes back the same way. Our guide to chargeback representment walks through that response.
How does a chargeback work, step by step?
Steps 1 through 6 happen on every chargeback. Steps 7 and 8 only happen when the issuer keeps pushing after you respond.
- The cardholder disputes a charge with their card issuer.
- The issuer checks the claim against the network's dispute conditions and, if it qualifies, sends the transaction back to your acquirer.
- Your acquirer debits the amount from your merchant account and notifies you.
- You review the dispute and pull the transaction records.
- You accept the loss, or you respond to your acquirer with an explanation and evidence before the deadline on the notice.
- Your acquirer forwards your response to the issuer.
- If the issuer still disagrees, it can continue the dispute through pre-arbitration.
- If neither side backs down, the case goes to arbitration, and the card network reviews it and rules.
Steps 1, 4, and 5 follow Visa's own outline for merchants: a cardholder disputes a transaction, you review the dispute and find the transaction records, then you respond to your acquirer. Step 3 is where the money moves. Visa's merchant dispute guide explains that when a dispute is valid, the acquirer deducts the amount from your account, and if the funds aren't there, the acquirer must cover the loss itself. That's one reason acquirers keep an eye on your chargeback history.
Steps 7 and 8 are the escalation path. Mastercard's documentation describes how an issuer can continue a dispute after the chargeback cycle through pre-arbitration and arbitration. Its Chargebacks Made Simple guide adds two rules worth knowing: when the acquirer takes no action for 30 calendar days after a pre-arbitration case is submitted, Mastercard moves the funds automatically, and an arbitration ruling can be appealed within 45 days.
Silence is the worst possible response. Visa warns that if you or your acquirer don't respond within the time specified on the request, the case may end with an unfavorable outcome, and that the time allowed may vary depending on your acquirer.
How long does a chargeback take?
Longer than most owners expect. Mastercard says the entire chargeback process can take up to 120 days, and a dispute can arrive months after the sale. These are the time frames we could confirm in network and federal sources:
| Stage | Time frame | Who sets it |
|---|---|---|
| Cardholder sends a billing-error notice to a credit card issuer | Within 60 days after the first statement showing the error | Regulation Z |
| Issuer acknowledges that notice | Within 30 days of receiving it | Regulation Z |
| Issuer resolves the billing error | Within two complete billing cycles, and no later than 90 days | Regulation Z |
| Issuer files a Visa "not received" dispute after a merchant goes out of business | No later than 120 days from the date the cardholder expected the goods, and never more than 540 days after the sale | Visa |
| You respond to the chargeback | Set by your acquirer; Mastercard says typically 20 to 45 days after you're notified | Your acquirer |
| Acquirer ignores a Mastercard pre-arbitration case | Funds move automatically after 30 calendar days | Mastercard |
| Arbitration ruling is appealed | Within 45 days of the ruling | Mastercard |
The Regulation Z rows come from the CFPB's text of § 1026.13, billing error resolution. The Visa row comes from Visa's own dispute rule update, which also works through a date: for a third-party gift card processed on November 1, 2021, the last day to dispute was March 1, 2022, 120 days later.
So keep records longer than feels necessary. A sale from the spring can come back in late summer, and we'd hold on to receipts, delivery records, and customer messages for at least a year, because Visa's Compelling Evidence 3.0 rules look back as far as 365 days for a customer's earlier purchases. Your own window, by contrast, is short. Your processor needs time to package and submit your response, so treat the date on the notice as the last possible day, not the target.
What does a chargeback cost a merchant?
A chargeback costs more than the sale, and Visa's guide is blunt about it: you can lose both the dollar amount of the disputed transaction and the related merchandise, plus your own internal costs. It also notes that, in most cases, your full financial and administrative liability for disputes is spelled out in your merchant agreement.
Here's a worked example. An online shop in Pittsburgh ships a $240 order of goods that cost it $110. Three weeks later, the real cardholder reports the card number stolen and disputes the charge. The shop didn't use 3-D Secure and has no delivery confirmation, so it accepts the chargeback.
- The acquirer debits the $240 sale from the shop's account.
- The goods, which cost $110, are gone for good.
- The processor charges a chargeback fee. We'll use $20 for the example; your agreement sets the real number.
- Compared with the sale the owner thought they'd made, the shop is $260 worse off ($240 plus $20).
- Compared with never taking the order at all, it's $130 worse off ($110 plus $20), before shipping and staff time.
Friendly fraud can sting even more. Visa says first-party misuse, where the real cardholder disputes a purchase they made, can cost merchants up to double the original transaction amount and pushes up their chargeback ratio.
That ratio is the hidden cost. Chargebacks count toward the dispute ratios that card networks monitor, and Visa notes that acquirers may have their own risk assessment parameters and fees, even for a merchant that meets Visa's dispute ratio target. We list the network thresholds in our guide to preventing chargebacks. If your processor charges a fee per chargeback, look for it on your monthly statement; our guide to reading a merchant statement shows where fees like that sit.
What are chargeback reason codes?
Every chargeback carries a reason code, which Visa calls a dispute condition. It tells you what the cardholder is claiming and what evidence can answer it. Visa sorts its conditions into four categories, and Mastercard's guide uses four similar groups.
| Visa category | Visa conditions (examples) | Mastercard group | What the cardholder is saying |
|---|---|---|---|
| Fraud (10.x) | 10.4 Other Fraud, Card-Absent Environment | Fraud-related | "I didn't make this purchase" |
| Authorization (11.x) | 11.2 Declined Authorization | Authorization-related | The sale went through without a valid approval |
| Processing Errors (12.x) | 12.5 Incorrect Amount; 12.6 Duplicate Processing/Paid by Other Means | Point-of-interaction error | "I was charged twice" or "I was charged the wrong amount" |
| Consumer Disputes (13.x) | 13.1 Merchandise/Services Not Received; 13.3 Not as Described or Defective Merchandise/Services; 13.6 Credit Not Processed | Cardholder dispute | "It never came," "it isn't what I ordered," or "I never got my refund" |
The category decides your defense. Fraud claims need proof that the real cardholder made the purchase; for online orders, our guide to card-not-present transactions explains how Visa's Compelling Evidence 3.0 rules work. For "not received," you need proof of delivery. For "not as described," send the product listing, invoice, or contract, and keep in mind that Visa advises merchants to address each point the cardholder has made. In a quality dispute, Visa adds, a neutral third-party opinion may help back you up.
Recurring billing has its own trap. Picture a fitness studio in Columbus that bills members monthly. A member says they canceled in March and keeps getting charged. Visa's advice is to cancel immediately when a customer asks and confirm the cancellation in writing with its effective date. Studios that bill through a virtual terminal with recurring billing should make that confirmation email part of the routine. Our guide to gym membership billing covers the cancellation rules some states set for gyms.
Processing errors are the hardest to fight because they're usually real. For a duplicate charge, Visa's guide says to provide documentation showing the two transactions are separate. If they aren't, accept the chargeback and fix whatever caused the double charge.
What rights does a cardholder have under Regulation Z?
The card network rules decide how money moves between banks. Federal law decides what a credit card issuer owes its cardholder, and for credit cards that law is Regulation Z (Truth in Lending). Three parts of it shape the chargebacks you see.
Billing errors
A credit cardholder can send the issuer a written billing-error notice within 60 days after the first statement that shows the error. Billing errors include charges for goods or services the consumer didn't accept or that weren't delivered as agreed, and for that kind of claim the cardholder doesn't have to contact you first. While the issuer investigates, the cardholder can withhold the disputed amount, and the issuer may not try to collect it.
One line in that rule matters a lot to merchants: on a nondelivery claim, the issuer can't deny the assertion unless a reasonable investigation shows the goods or services were actually delivered, mailed, or sent as agreed. That's where your delivery records come in.
Claims and defenses
A quality complaint about goods the customer accepted isn't a billing error under that rule. A separate provision lets a cardholder assert claims and defenses from a purchase against the card issuer when the purchase was over $50 and made in the same state as the cardholder's address, or within 100 miles of it. The cardholder must have tried to resolve the dispute with the merchant first, though the rule doesn't require any special procedure for that.
Unauthorized use
A cardholder's liability for unauthorized use of a credit card can't exceed the lesser of $50 or the value of the unauthorized charges made before they notify the issuer. That cap protects the cardholder, not you. Once the issuer absorbs a fraud claim for its customer, the network rules decide whether it can charge the sale back to you.
These are federal rules, so a cardholder in Ohio has the same rights as one anywhere else in the United States. What changes from case to case is how much evidence you have.
Should you fight a chargeback or accept it?
Fight the ones you can win, and accept the rest quickly. Visa's guide points out that accepting a dispute can save time and expense, and a case you can't support with documents is rarely worth an afternoon. Use this table as a starting point:
| Situation | Our call | What to send |
|---|---|---|
| You refunded before the dispute arrived | Fight | The credit record, with its amount and date |
| You charged twice or the wrong amount | Accept | Nothing; fix the cause instead |
| Customer says it never arrived, and you have proof of delivery | Fight | Tracking and signed proof of delivery to the right address |
| Customer says it's not as described | Fight if your listing backs you up | The product description, invoice, photos, and a point-by-point rebuttal |
| Fraud claim from a returning online customer | Fight | Two earlier undisputed orders with matching IP address or device data |
| Fraud claim on a first-time online order with no authentication | Usually accept | There's little to send |
| Small order where the evidence would take hours to gather | Usually accept | Nothing |
The refund row deserves a note. Visa reminds issuers that they must not pursue disputes unless the cardholder has suffered a financial loss, and that the onus is on the issuer to check whether the cardholder already received a credit from the merchant. If you refunded first, say so plainly and attach the proof.
Here's the test we'd use before spending an hour on a response: can you answer the specific claim with a document rather than an argument? If the honest answer is no, accept the chargeback and put that hour into prevention.
What to do the day a chargeback notice arrives
- Note the reason code and the response deadline, and put a reminder on your calendar a few days earlier.
- Check whether you already refunded or reversed the sale.
- Pull the order record: receipt, authorization, AVS and CVV2 results, IP address, device data, and customer messages.
- Gather delivery or service records: tracking, signed proof of delivery, or a signed work order.
- Match your evidence to the reason code and answer each claim the cardholder made.
- Keep the rebuttal short and factual, with every document labeled.
- Submit through your processor before the deadline and save a copy of what you sent.
- Log the reason code and the outcome, because Visa recommends tracking disputes and dispute responses by condition.
Step 8 is the easiest to skip and the one that pays off: after a few months, the log shows whether your problem is fraud, fulfillment, or a confusing descriptor, and each has a different fix.
