Top Ecommerce Chargeback Reasons and How to Prevent Them

Chargebacks are becoming increasingly common because they take only a few clicks.

Chargebacks cause major problems for ecommerce merchants, and the issue is no longer limited to stolen credit cards or obvious fraud. Many disputes are now driven by things like friendly fraud and subscription misunderstandings, especially because online tools allow consumers to file claims with just a few taps inside their banking apps.

The financial impact is extremely noticeable, too, as Mastercard forecasts global chargeback costs could reach $42 billion by 2028, with nearly half tied to fraudulent disputes. Mastercard also reports that friendly fraud now represents about 75% of fraud experienced by online businesses.

Reducing disputes requires an entirely new strategy that combines fraud prevention, post-purchase communication, customer transparency, and representment processes. Businesses that don't adapt could lose out on revenue, making it a problem that should be addressed sooner rather than later.

Why Are Chargebacks So Common in Ecommerce?

As global ecommerce sales continue to climb, merchants are processing a larger volume of card-not-present (CNP) transactions, which naturally carry higher fraud and dispute risk than in-store purchases. Every additional digital payment creates another opportunity for fraud or post-purchase dissatisfaction, which is where many issues arise.

It's also far easier than ever before for customers to file disputes. Many banks and card issuers allow customers to file chargebacks directly through their mobile banking apps in a matter of seconds, and they don't even have to speak to the retailer first.

Subscription services are part of the problem, too. Customers might forget about these subscriptions or anything they've signed up for with automatic renewals. Digital goods and downloadable products add even more complexity, especially when customers expect instant fulfillment and refunds.

According to Mastercard's 2025 State of Chargebacks report, merchants and issuers have both noticed significant increases in chargeback volume. Global chargebacks are expected to grow by 24% between 2025 and 2028, too, so there's no sign of this issue going away.

This shift means that reactive dispute management isn't an option. Winning chargebacks after they happen can help recover some revenue, but you'll still lose money, and you need a strategy that prevents disputes before customers ever contact their bank.

Is Fraud Still the Number One Cause of Chargebacks?

Fraud is everywhere, but its definition has changed significantly in recent years. Merchants now have to deal with a mix of true fraud, friendly fraud, merchant error, and customer confusion, all of which can result in costly disputes.

True fraud still exists, and it typically involves cybercriminals using stolen credit card details when purchasing goods or services. Cardholders in these situations legitimately don't recognize the transaction and file disputes to recover their funds when they see the purchase on their statement.

However, a growing percentage of chargebacks now falls into the category of friendly fraud. This type of fraud is becoming more common and is usually the result of customers intentionally or accidentally disputing legitimate purchases. There are cases where these customers genuinely forget a purchase or misunderstand subscription renewals, but they might also just want to bypass the merchant entirely when seeking a refund because it's quicker and easier.

Disputes can also arise because of poor post-purchase communication. For instance, the likelihood of a customer not recognizing a charge can increase because of:

• Generic billing descriptors
• Limited shipping updates
• Confusing cancellation processes
• Slow customer service responses

Many retailers are noticing that disputes don't always come down to malicious intent, as customers simply don't have the information they want.

Fraud isn't straightforward, so new chargeback prevention methods are necessary to help retailers tell the difference between legitimate customers and those who are trying to commit crimes.

What Are Some of the Most Common Chargeback Reasons Retailers Face?

Chargebacks can happen for many reasons, but retailers will notice that some issues come up far more than others. Some are tied to legitimate fraud, while others are the result of operational issues or poor communication after checkout. Understanding the main causes of these disputes makes it easier to reduce chargeback rates.

1. "I Didn't Authorize This Purchase"

Unauthorized transaction claims are a common chargeback reason in ecommerce. What usually happens is that stolen payment credentials are used to place purchases without the cardholder's knowledge. These scenarios can arise after phishing attacks, data breaches, account takeover schemes, or card testing activities performed by cybercriminals.

However, friendly fraud can also lead to customers filing unauthorized transaction claims. Customers may forget about a purchase or allow a family member to use their card, for example, only to dispute the transaction later on when they don't recognize it. These situations are especially common with subscription renewals or digital purchases because the purchase likely didn't occur recently and, therefore, is easy to forget.

Synthetic identity fraud is another growing problem where fraudsters combine real and fake personal information to create new identities. Traditional verification systems might not notice that these new identities are fraudulent right away, and the accounts could be active for months before the cardholder notices them.

2. "My Order Never Arrived"

Delivery-related disputes are a major source of chargebacks. Customers increasingly expect fast, highly visible shipping experiences, and even minor fulfillment issues can turn into disputes if there isn't any communication when there's a delay.

Of course, there's always the possibility that a package didn't arrive, as supply chain delays and carrier mistakes happen all the time. The problem occurs when a customer says the item didn't arrive when it did and then files a chargeback.

Porch theft is another challenge, particularly for high-value items left unattended after delivery. The carrier will have delivered the item, but the customer didn't receive it, creating problems for the retailer when the customer files a dispute.

Tracking gaps can also create unnecessary disputes. Customers tend to get frustrated if they don't receive timely updates and could file a dispute as a result. Many consumers now expect Amazon-level fulfillment transparency regardless of the retailer's size, which simply isn't feasible.

With mobile banking apps making chargebacks extremely easy, merchants often have very little time to resolve shipping concerns directly. The result is more chargebacks and significant issues for retailers.

3. "The Product Doesn't Look as Described"

Product-related disputes usually arise when there's a major difference between what the customer expected and the item they received. This situation commonly pops up for retailers selling clothing and beauty products because shoppers are buying those items exclusively based on appearance.

Marketplace environments create even more risk, because product quality may vary between sellers. A customer might have bought an item from a different seller the last time and expect your similar product to be the exact same, only to file a chargeback when it is not.

4. "I Forgot About the Subscription"

Recurring billing disputes continue to grow alongside the expansion of subscription-based ecommerce models. Streaming services, software platforms, memberships, replenishment programs, and free trial offers can be confusing because there are recurring charges, creating more opportunity for chargebacks.

Customers might:

• Forget that they enrolled in a subscription service
• Not realize that a free trial has become a paid plan
• Become frustrated when the cancellation process is difficult or time-consuming

These situations could lead to customers disputing charges through their bank rather than contacting the merchant.

5. "I Requested a Refund but Didn't Get One"

Refund-related chargebacks often happen when customers believe the merchant didn't deal with their issue quickly enough. Delayed responses or slow refund processing can push consumers toward filing disputes with their bank because these customers don't want to wait to get their money back.

The refund could already be in progress in these situations, but poor communication means the customer doesn't know that. Customers who can't reach support are particularly likely to escalate directly to a chargeback.

It's important for retailers to realize that chargeback prevention doesn't just mean blocking fraud at checkout, as there are many reasons customers go this route. As a result, the best prevention strategies combine fraud detection and customer experience optimization into a single revenue protection approach.

How Are Visa and Mastercard Changing Chargeback Rules?

Card networks are changing their chargeback frameworks in response to the increase in friendly fraud. For instance, Visa and Mastercard have placed greater emphasis on data-sharing and behavioral analysis, giving merchants a better chance to prevent and fight disputes.

One example is Visa's Compelling Evidence 3.0 (CE 3.0) framework. The gist is that CE 3.0 allows retailers to submit more evidence during friendly fraud disputes, which can include:

• Transaction history
• Device data
• IP addresses
• Customer account activity
• Proof of previous purchases

The goal is to help issuers distinguish between genuine fraud and friendly fraud misuse more accurately.

Mastercard has taken a similar approach through its First-Party Trust initiative, which expanded internationally in 2025. The program focuses on sharing enhanced transaction intelligence between merchants, issuers, and acquirers to identify patterns associated with friendly fraud.

Mastercard now encourages merchants to provide more behavioral and device-level evidence during dispute investigations to strengthen representment efforts.

These changes show that chargeback management requires retailers to do more than respond to disputes after they happen, as a proactive strategy is now necessary.

Businesses that can collect and analyze device intelligence and post-purchase activity are far better positioned to prevent disputes and challenge friendly fraud claims moving forward.

FAQ: Reasons for Ecommerce Chargebacks

Why do ecommerce businesses experience so many chargebacks?

Chargebacks are increasing because customers don't have to present a card to buy online. Consumers can also file disputes directly through mobile banking apps in just a few clicks, making chargebacks easier than ever to initiate.

Are most chargebacks caused by actual fraud?

A lot of chargebacks are the result of real fraud, but that isn't always the case. While stolen cards and unauthorized purchases still account for many disputes, friendly fraud is also a fast-growing chargeback category. In many cases, customers dispute legitimate transactions because they forgot about a purchase or became frustrated with the refund process.

What types of chargebacks do retailers have to deal with most often?

Some of the most common reasons for ecommerce chargebacks include:

• Unauthorized transaction claims
• Delivery disputes
• Product not as described complaints
• Subscription billing confusion
• Refund-related disputes

Many of these issues come from operational breakdowns or customer communication gaps rather than intentional fraud.

How are Visa and Mastercard changing chargeback rules?

Visa's Compelling Evidence 3.0 makes it easier for retailers to submit detailed information when a customer files a chargeback. Mastercard expanded its First-Party Trust rules, too, so retailers and issuers can work together to fight chargeback claims.
