What is a chargeback? How it works, and what it costs you

The short answer

A chargeback is when your customer asks their bank to reverse a card payment, and the bank does. The money comes back out of your account, usually with a fee on top.

Visa calls it a dispute. It defines a dispute as “the reversal of the value (or partial value) of a transaction by the card issuer to the acquirer” (Visa). The issuer is your customer’s bank. The acquirer is the bank or processor that handles your card sales. Your acquirer then passes the reversal on to you.

You can fight a chargeback with evidence. But you have a deadline, and if you miss it you lose.

How a chargeback works, step by step

Visa’s merchant guide describes the path like this (Visa Dispute Management Guide for Merchants):

1. Your customer contacts their bank. They may not recognize the charge, may not have got what they paid for, or may think something went wrong.
2. The bank checks the claim. If it meets the network’s rules, the payment is sent back through the card network to your acquirer.
3. Your acquirer contacts you. It tells you the reason and asks for any evidence. Visa says “Each step in the dispute process has a strict deadline.”
4. You respond, or you accept it. You send your evidence to your acquirer, not to the customer’s bank.
5. The issuer decides. Mastercard says your acquirer forwards your evidence through the network to the issuer, and “The issuer then makes the final decision” (Mastercard). If you win, the money comes back to you.

Visa says a dispute can move on to further review stages after that, as set out in its rules. Most small businesses never get that far.

How long you have to respond

Your acquirer sets your deadline, and it’s often shorter than the network’s. Mastercard puts it this way (Mastercard):

• “Timeframes for acquirers average 10-35 days.”
• Network deadlines are “typically 20 to 45 days after the merchant is notified.”
• “The entire chargeback process can take up to 120 days.”
• If you miss the acquirer’s deadline, “they will lose the chargeback dispute by default.”

Visa doesn’t publish fixed day counts for merchants in its guide. It says to “Check with your acquirer to understand the timelines.”

Your customer has deadlines too. For a billing error on a credit card, the CFPB says the customer should send the card company a written notice “within 60 calendar days after the charge appeared on your statement.” The card company then has 30 days to confirm it got the dispute (CFPB).

Chargeback reason codes

Every chargeback comes with a reason code. Mastercard says the acquirer will give you one, and that your evidence “should directly address the chargeback reason code.”

Visa groups its codes into four categories (Visa Dispute Management Guide):

Visa category	What it means	Examples
10: Fraud	The cardholder says they didn’t make or allow the payment	10.4 Other Fraud, Card-Absent Environment
11: Authorization	The payment didn’t get a valid approval	11.2 Declined Authorization, 11.3 No Authorization / Late Presentment
12: Processing errors	Something went wrong in how the sale was run	12.5 Incorrect Amount, 12.6 Duplicate Processing / Paid by Other Means
13: Consumer disputes	The customer has a problem with what they bought	13.2 Cancelled Recurring Transaction, 13.3 Not as Described or Defective, 13.6 Credit Not Processed

Mastercard and other networks use their own codes. Your acquirer’s notice tells you which one applies.

One fraud rule matters a lot for in-person sales. Visa says if a chip card is swiped or typed in instead of read by the chip, “you may be held financially responsible for certain types of fraud.” That’s the EMV liability shift. Mastercard says merchants are “generally liable for all chargebacks” on card-not-present sales, but not for genuine fraud on card-present sales.

What providers charge per chargeback

On top of losing the sale, your provider usually charges a fee. From each provider’s own published pricing:

Provider	Chargeback or dispute fee	The detail
Helcim	$15 if you lose	$0 if the case is resolved in your favor
Lightspeed	$15	“The only thing you can expect is a $15 chargeback fee, should one occur.”
Stripe	$15 per dispute	Plus a $15 countered fee if you respond manually. You get that second fee back only if you win.
PayPal POS	$20 per chargeback	Plus a $15 standard dispute fee ($30 for high-volume disputes)
Square	No dispute fee	“There are no fees for dispute management services for chargebacks.” But “The processing fees for the payment aren’t refunded back to you.”

Stax doesn’t publish a chargeback fee on its pricing page. If a provider you’re looking at doesn’t list one, ask for it in writing before you sign.

Mastercard adds that “regardless of whether the merchant is liable for the chargeback, they must pay the chargeback fee.” So even a chargeback you can’t be blamed for usually costs you something.

Why your chargeback count matters

Winning a case doesn’t erase it. Mastercard says every dispute still counts toward your chargeback ratio, which is used to judge how risky your business is. It says “A high ratio may result in higher fees and potentially even the risk of having their merchant account frozen.”

If your provider has already flagged you, see our guide to high risk merchant accounts.

How to prevent chargebacks

Most come from simple, fixable problems. Visa lists causes such as unclear return or refund policies, delivery delays, and customers not recognizing the business name on their statement. Its tips (Visa):

• Show your policies at the sale. “State your policies clearly at the time of transaction,” and print them on the receipt.
• Use a name customers know. Submit the business name customers recognize most. Visa’s guide says to check that the name on their statement matches the one they see when they buy.
• Charge once. Void wrong receipts and process each sale only once.
• Don’t charge before you ship. Visa says not to deposit a sale until the goods have shipped.
• Warn about delays. Tell the customer about any delay and the new date.
• Deposit quickly. Visa suggests submitting sales “ideally within one to five days of the transaction date.”
• Use the chip. Let the terminal read the chip instead of swiping when a chip card is used.
• Refund fast. Visa says if a customer contacts you and a refund is fair, issue it quickly. That can stop a formal dispute before it starts.

How to respond to a chargeback

1. Read the reason code first. Visa says “Effective responses focus on relevance and clarity, not volume.” More paper doesn’t help if it doesn’t answer the claim.
2. Gather the right proof. Mastercard lists delivery confirmation, purchase or usage history, the refund policy the customer agreed to, address and CVV matches, and emails or call records with the customer.
3. Show a refund if you gave one. Include the date, amount and transaction reference.
4. Send it before the deadline. Send everything to your acquirer, or through your provider’s dashboard.
5. Decide if it’s worth fighting. Mastercard says that if your evidence is weak, you may want to reconsider disputing it.

Before you choose a provider, compare what each one charges when things go wrong, not just its rate.
