How Credit Card Chargebacks Work, Step by Step
A chargeback is a sale pulled back through the card system. Here is how the dispute moves from a cardholder's complaint to the merchant and back, in the words of Visa and Mastercard.
A customer calls their bank about a charge. Days later, money leaves a shop's account. That pull-back is a chargeback, and this page walks through the whole trip. Every step here comes from the rules Visa and Mastercard publish themselves. If you hold a card rather than run a shop, start with credit card charge backs from the cardholder's side. If you run a shop, read on for both sides of the counter.
What a chargeback is, and how it differs from a refund
In Visa's guidelines, a dispute is a transaction the issuer sends back to an acquirer. In plain words, the bank that issued the card sends the sale back through the system instead of leaving it where it landed.
A refund is different, and the difference matters. Discover's article says a refund, unlike a chargeback, comes from a merchant. The shop decides to give the money back. In a chargeback, the cardholder's bank takes it back. The merchant is not asked first.
The four players: cardholder, issuer, acquirer, merchant
Four names come up again and again, so fix them now.
The cardholder is the person holding the card. Visa's guidelines define an issuer as a client that enters a contract with a cardholder to issue card products in most regions. That is the bank that sent the card out.
Now look at the other side. Visa's guidelines define a merchant as an entity that accepts a card for sales or funds transfers and submits the transaction to an acquirer. The acquirer is the bank on the merchant's side of the deal, the one that processes card payments for the shop.
One more thing about how these four line up. Visa's guidelines say the main interaction in a dispute is between a card issuer and an acquirer. The cardholder and the merchant start and end the story, but the banks carry it.
How a chargeback starts: reason codes and categories
It starts with a complaint. Visa's guidelines say a cardholder files a transaction dispute with their bank, which sends it to the merchant card processor. The issuer may ask the cardholder for a detailed explanation of the problem before doing anything.
Then the bank sorts it. Mastercard's guide says an issuer may start a chargeback when the transaction meets the requirements of a chargeback reason code. Each code is a named reason with its own rules.
The two big networks group these codes in similar ways. Visa sorts disputes into four categories: 10 Fraud, 11 Authorization, 12 Processing Errors and 13 Consumer Disputes. Mastercard chargebacks fall into four categories: Authorization, Cardholder disputes, Fraud, and Point-of-Interaction Error.
There is a limit on how far one code can stretch. Under Mastercard's rules, an issuer gets only one chargeback for each presented transaction amount. Mastercard's guide says a chargeback may be for the total transaction amount or a lesser amount. The total being charged back must not exceed the total transaction amount.
What happens next: the dispute reaches the merchant
The banks talk first. Visa's guidelines say the card issuer sends the dispute to the acquirer, which may or may not involve the merchant.
When the acquirer acts, the money moves. Visa says the acquirer looks into each dispute, and if it is valid, takes the amount from the merchant's account. Visa's guidelines say the acquirer informs the merchant when a dispute is valid. The shop is told, not asked.
How a merchant responds: accepting or contesting with evidence
A shop has two moves. Under Visa's rules, a merchant has two options: agree to the dispute, or fight it by passing supporting documents to its card processor. Agreeing means the shop does not get the money back. Rejecting means making a case.
Visa's guidelines say a merchant may respond to a dispute through its acquirer under certain circumstances. The evidence has to be usable. Visa dispute evidence must be easy to read and in English, or come with an English translation.
If the case is lost, the loss lands somewhere. Visa's guidelines say if a merchant cannot remedy a dispute, the loss belongs to the merchant. And if the merchant account lacks funds for the disputed amount, Visa's guidelines say the acquirer must cover the loss.
Second presentment: sending the transaction back
The word "presentment" has a plain meaning here. Mastercard calls it first presentment when the acquirer sends the transaction to the issuer to post to the cardholder's account. That is the normal sale, the first trip through the system.
In Mastercard's process, second presentment is the sale going back the other way. The acquirer may second present when the chargeback did not meet the reason code rules or it can answer the original dispute. There is one case where it is required. If a cardholder got both a chargeback credit and a merchant refund, the acquirer must second present showing the refund. The customer should not end up paid twice.
When the dispute escalates: pre-arbitration and arbitration
A chargeback is not always the end. Under Mastercard's rules, after the chargeback cycles, the issuer may continue the dispute through pre-arbitration and arbitration case filing.
Pre-arbitration comes first, usually. For Mastercard disputes other than ATM and Maestro transactions, an issuer that wants to continue must first file a pre-arbitration case. The exception is narrow. For ATM and Maestro transactions, pre-arbitration is optional, and the issuer may go straight to an arbitration case.
The acquirer then has choices. If the acquirer takes no action on a pre-arbitration case, it accepts financial responsibility for the transaction. The acquirer may reject a pre-arbitration case with a rebuttal and any relevant documents.
If the two sides still cannot agree, the network steps in. When the issuer and acquirer cannot resolve an arbitration case, Mastercard decides who is responsible. Mastercard rules on an arbitration case as filed and assigns liability based on its merits and the rules. Mastercard posts its arbitration decision in the Mastercom application and moves the disputed amount between the two sides.
There is a penalty for skipping steps. Mastercard holds the issuer liable if it skipped a required pre-arbitration case or filed arbitration too late.
Appeals: the last step
A Mastercard arbitration ruling can be challenged. An appeal is a written request asking Mastercard to reconsider its ruling. A party must get its appeal to Mastercard within 45 calendar days of the Mastercard ruling.
The window is tight in another way too. Mastercard's guide says new or updated information will not be accepted in any appeal. The appeal argues from what was already on the table.
Time limits and documentation rules that decide outcomes
Visa's guidelines say each step in the dispute cycle has a defined time limit during which action can be taken. Each step of a Visa dispute has a set time limit, so a late answer can lose the case. Visa's rules say a side that does not respond in time closes the dispute cycle and is responsible for the amount.
Paperwork quality counts as much as speed. Mastercard's guide says customers must provide support documentation with enough detail so all parties can understand the dispute. Mastercard's guide says lack of sufficient detail may result in an unfavorable ruling decision.
Preventing chargebacks before they start
The easiest dispute to win is the one that never exists. Visa's guidelines say merchants can prevent many unnecessary disputes by training staff to pay attention to a few details. Visa's guidelines say most disputes come from improper transaction-processing procedures and can be prevented with training and attention to detail.
That claim is worth a second read. Most, not some. The causes are often inside the shop's own routine, which means the fixes are too.
For a closer look at one network's version of this process, see chargeback mastercard. For the basics in one place, the site's page on chargeback credit card covers the ground. And for the term itself, chargeback defines it plainly.
So, how do credit card chargebacks work? A cardholder complains, an issuer checks the reason, and the acquirer pulls the money. The merchant answers or accepts. The banks keep going until someone gives in or a network rules. Know the players, keep your records, and mind the clock.
