What is a chargeback?

Chargebacks have an important role to play in the payments ecosystem. They give consumers recourse against fraud and errors, which preserves public confidence in credit and debit card payments. This is especially significant in e-commerce, where the risk of third-party and merchant fraud is perceived to be much higher.

The downside of chargebacks is that they can be a huge, costly headache for the merchants who have to deal with them. Many consumers ask for chargebacks over problems that chargebacks were never intended to address, or dispute transactions without even attempting to contact the merchant first.

Global chargeback rates keep increasing year-to-year, and recent gains in e-commerce have led to a commensurate increase in fraud and chargeback activity. With chargebacks on the rise, more businesses are taking action to defend themselves. What are chargebacks, and what do merchants need to know in order to prevent and fight them as effectively as possible?

When a cardholder disputes a charge, their issuing bank will review the transaction and decide if the dispute is valid. If they believe that it is, they will provide the cardholder with a provisional credit and work with the card network and the acquiring bank to finalize a chargeback.

Chargebacks for credit cards were first implemented in the 1974 Fair Credit Billing Act (§ 161. Correction of billing errors), an amendment to the Truth in Lending Act.

Debit card chargebacks were implemented later by the Electronic Fund Transfer Act in 1978. These acts were intended to outline protective measures for consumers.

Chargebacks were created in response to widespread abuse by fraudsters who would use stolen credit card information to make purchases. Before the Fair Credit Billing Act, there wasn’t much cardholders could do to get their money back from merchants who had received these fraudulent payments.

The chargeback process allows consumers to get their refunds from their banks, and to let banks (rather than cardholders and merchants) make decisions on how to handle the situation. While the process was not yet called a chargeback, it would become the foundation for the dispute system we know today.

How Do Chargebacks Work?

Chargebacks are initiated by cardholders, evaluated by banks, and paid for by merchants. A single chargeback, from initiation to resolution, can last months or even years.

While banks will sometimes file chargebacks for things like authorization or processing errors, most chargebacks occur when a cardholder contacts their bank to dispute a charge on their account. Usually, they do this because they don’t recognize the charge and believe it to be fraudulent.

In some cases, a cardholder might dispute a charge because they feel they didn’t get what they paid for and the merchant has refused to resolve the issue.

Once a chargeback has been initiated, it will go back and forth between the issuing bank and the merchant until either one of them agrees to accept liability or until the card network must be called in to resolve the dispute.

1. When a cardholder disputes a transaction with their issuing bank, the bank decides whether or not the customer has grounds to file a chargeback.
2. If a chargeback is granted, the bank will notify the acquiring bank—AKA the merchant’s bank—and debit the funds from the merchant’s account.
3. The merchant can either accept the chargeback or fight it by resubmitting the charge along with a rebuttal letter and the necessary evidence to disprove the claim. This process is called representment.
4. The issuing bank will review the new evidence and make a decision. If they find in favor of the merchant, the funds will be returned.
5. At this point, any party unhappy with the decision can contest the issue further by initiating pre-arbitration. This most often occurs when the issuing bank decides in the merchant’s favor, but then receives new evidence that puts that decision in question.
6. If neither party accepts liability during pre-arbitration, the chargeback moves to arbitration. Here, the card network will examine the evidence and make a final decision. This decision can’t be appealed further, and the losing party will be required to pay hundreds of dollars in fees.

Time limits for merchants to respond to a dispute vary based on the credit card network and the reason code. Note that the timer begins when the chargeback is initiated, not when the merchant is notified, so the merchant’s deadline may not be the exact time frame outlined by the card network’s policies.

If a merchant’s chargeback ratio exceeds certain thresholds established by the card networks and other financial institutions they do business with, they may face fines, additional chargeback fees, and even termination of their merchant account. The most common threshold is 1%, but Visa recently lowered theirs to 0.9%. 

We do have some data from a 2018 survey by Javelin Research showing that nearly half of all customers have disputed a charge, and a majority of those have disputed more than one.

We also know that chargebacks continue to grow year after year. A 2018 study by Aite Group predicted that the total value of chargebacks would climb to $35 billion by 2021, and given the increase in disputes that accompanied the COVID-19 pandemic, it wouldn’t be surprising to find we’ve already far exceeded that number.

The bank will typically give the cardholder a provisional credit for the amount of the charge while they investigate the validity of the claim. The cardholder should be prepared to describe the problems they had with the merchant and the steps they took to resolve the matter.

In order to identify the reason a customer disputed a charge, it can be helpful to examine the reason code on the chargeback.

Every chargeback has a reason code associated with it. The major card networks (Visa, Mastercard, Discover, and American Express) established these codes to clearly identify the reason a chargeback was requested.

While the reason code will tell you how the cardholder justified the dispute to their bank, it’s important to keep in mind that this isn’t always the real reason for the chargeback.

Some customers may incorrectly think that a charge on their account was unauthorized because they don’t recognize the name of the business listed in the transaction description. Others may have forgotten about a recurring charge they signed up for.

There are also some customers who want to file a chargeback because of a negative experience they had with the merchant, but know that the reason they have isn’t a legitimate basis for a dispute. In order to get the chargeback, they lie to the bank about their reason for requesting one. In some cases, a customer may have made a purchase with the intention of fraudulently disputing the charge later in an effort to get their money back.

If a cardholder is a victim of true fraud (unauthorized use of stolen credit card credentials), then a chargeback is most legitimate and ethical way for the issuing bank and the merchant to resolve the issue.

Customers can also file chargebacks when they didn’t receive the product or service they paid for, whether because of a lost or damaged shipment or an incorrect item being sent. Being double-charged or overcharged the agreed purchase amount is another legitimate reason for a dispute.

However, problems like these are usually resolved more quickly and easily when the customer contacts the merchant, and a chargeback should only be used when the merchant is uncooperative.

Then there are the customers commit first-party misuse, better known as "friendly fraud," by filing a chargeback without a legitimate reason.

Customers can’t dispute a charge simply because they are dissatisfied with the product or service they received. These issues must always be resolved with the merchant directly.

True Fraud

True fraud chargebacks are what chargebacks were invented for: unauthorized charges against a credit card by a scammer or identity thief. Merchants are strongly advised not to waste time or resources attempting to dispute these chargebacks.

True fraud chargebacks are best prevented through fraud prevention tools. AVS and CVV matching are the bare minimum, but many merchants also use multi-factor authenticators like 3-D Secure or third-party tools that use artificial intelligence and machine learning to weed out fraudulent transactions.

Friendly Fraud

Friendly fraud chargebacks are when customers report valid charges as fraudulent to get the charge reversed. They might do this deliberately, with malicious or criminal intent, or they might do it out of impatience or confusion. Friendly fraud chargebacks often masquerade as true fraud chargebacks, with the customer falsely claiming they never authorized the charge.

These chargebacks are difficult to prevent, but can be fought through representment to recover lost revenue. Customers who file friendly fraud chargebacks can also be blacklisted.

Merchant Error

Merchant error chargebacks occur when the cause of the chargeback is an error made by the merchant, such as shipping the wrong item. Disputes like this can sometimes be fought effectively, but the flaws in merchant operations these chargebacks reveal must be remedied to prevent similar future chargebacks.

Merchant error chargebacks can be prevented by improving business operations, by providing helpful customer service 24/7, and by having a generous refund policy.

The basic idea is that if an EMV card is used fraudulently and the merchant had not upgraded their processing equipment to EMV-compliant standards, the blame for that fraudulent transaction lies with the merchant.

The EMV Liability Shift caused most merchants to upgrade to EMV payment technology, which is much less vulnerable to fraud than traditional magnetic strips. However, it may also have resulted in an increase in fraudulent chargebacks. Savvy fraudsters have learned that if they convince a merchant to swipe a card with an EMV chip and later dispute that charge, the merchant will lose the dispute.

For card-present merchants, if the purchase is made using an EMV chip and the transaction turns out to be fraudulent, the issuing bank is held liable instead of the merchant. The merchant is still responsible for chargebacks arising due to merchant errors.

Merchants who receive a chargeback that they believe is unfounded have the right to contest the case. To do so, they’ll first need to submit a rebuttal letter to argue their case, along with a number of supporting documents and pieces of evidence. Exactly what evidence they’ll need will depend on the exact reason code associated with the chargeback.

When a merchant contests a cardholder chargeback, it then enters representment. During this process, the merchant provides information about the transaction and explains why they believe it was legitimate.

The merchant works with their sales department and/or their chargeback management company to build a dispute package that outlines the evidence and attempts to convince the issuing bank according to that bank’s guidelines.

Following this, the acquiring bank sends the information back through the credit card network to the issuing bank, who makes their decision and informs the involved parties.

If you plan to dispute a chargeback, it’s important to act quickly. Issuers often lag behind when notifying acquirers and merchants of chargebacks, so you may have a very small window in which to respond. Having a chargeback representment team at your disposal can help you act swiftly and efficiently, no matter what the deadline may be.

A prompt rebuttal letter can help you better address fraudulent chargebacks and win disputes. When done right, a rebuttal letter provides a simple overview of why the customer’s claims are false and what evidence you have to prove it. When disputing friendly fraud chargebacks, a good rebuttal letter combined with sufficient evidence will typically convince the issuing bank to rule in your favor and return your revenue.

Studying and fighting disputes will help you learn why they’re happening to you, and addressing those root causes is by far the best thing you can do to prevent future chargebacks.

Chargebacks can threaten your cash flow and put your merchant accounts at risk, too. They can increase your merchant account costs or cause your accounts to be shut down, preventing you from accepting payments altogether.
