Chargebacks are one of the main challenges faced by merchants that accept card payments, especially in ecommerce environments and card-not-present (CNP) transactions.
Their impact can go far beyond refunding a sale: they can generate operational costs, time spent gathering evidence, potential fees and, if a high volume of disputes accumulates, a higher level of risk for the merchant.
In this article, we explain what a chargeback is, why it occurs, how the process works and what merchants can do to prevent and manage chargebacks.
A chargeback is the reversal of a card transaction that may occur when the cardholder disputes a transaction with their issuing bank. Unlike a refund, which is handled directly by the merchant, a chargeback is initiated through the customer’s bank and may result in the transaction amount being returned.
As we will explain below, chargebacks can occur for different reasons, such as fraud, unrecognised charges, transaction errors or problems with a product or service. The purpose of the chargeback system is to protect consumers, but it can also negatively affect merchants if it is not managed properly.
The chargeback process usually follows a series of stages established by card schemes such as Visa and Mastercard. Although deadlines and procedures may vary slightly depending on the bank or payment provider, the usual process is as follows:
The cardholder identifies a charge they consider invalid and contacts their issuing bank to request a refund.
The customer’s bank reviews the claim and, if it considers it valid, initiates the dispute process in accordance with the relevant scheme rules. At this stage, the amount may be reversed within the payment system.
The merchant receives notification of the chargeback and the information required to respond, usually through its acquirer or payment service provider. One of the most important pieces of information is the reason code, which identifies the reason for the dispute.
As a merchant, you can accept the dispute or defend the transaction if you believe it was legitimate. To do so, you must provide any documentation that can demonstrate the legitimacy of the transaction, such as proof of delivery, invoices, copies of the order, communications with the customer, etc.
This process of defending a transaction is commonly known as representment.
If the issuing bank does not accept the evidence or if one of the parties disagrees with the outcome, the case may escalate to pre-arbitration. This stage allows additional arguments and documentation to be submitted in an attempt to avoid arbitration, which involves additional costs.
If no agreement is reached during pre-arbitration, the case is escalated to the card scheme’s arbitration committee, which reviews all the evidence and makes a final and binding decision. Both parties must comply with the decision, and additional costs may be charged to the relevant party.
The process ends with the resolution of the dispute, with two possible outcomes. If the chargeback is upheld, the merchant permanently bears the loss of the transaction amount. If the dispute is resolved in the merchant’s favour, the amount may be recovered in accordance with the applicable rules and procedures.
During this process, the merchant may also be charged a chargeback fee and, if the dispute rate is high, may face restrictions or penalties from the payment provider.
When a merchant decides to defend a transaction, simply stating that the transaction was legitimate is not enough. It is necessary to provide evidence that addresses the specific reason for the dispute and demonstrates that the transaction was authorised, processed correctly or, where applicable, that the product or service was delivered.
Depending on the type of dispute, some of the evidence a merchant may provide includes:
There is no universal list of documents that guarantees that a chargeback will be reversed. However, it is important to use the appropriate supporting evidence depending on the reason for the dispute and the rules of the relevant card scheme.
For example, if a customer claims that they did not receive a product, proving that the payment was authenticated using 3D Secure does not, by itself, prove delivery. In that case, the tracking number, delivery address and proof of receipt will be much more relevant.
Receiving a chargeback does not necessarily mean that you have lost the transaction amount. The first step is to review the reason for the dispute, analyse the transaction and assess the available evidence.
From there, you can accept the chargeback or defend the transaction. Below, we explain when each option may be appropriate and how to manage it:
Accept the chargeback if:
Defend the transaction if:
In any case, it is important to act within the established deadlines and submit only evidence that is relevant to the specific reason for the chargeback.
A chargeback does not only involve refunding the amount of a sale. For a merchant, a dispute can also generate additional costs, administrative work and a higher level of risk if a large number of claims accumulates.
The main consequences include:
In more serious cases, when the level of disputes exceeds established thresholds and the chargeback ratio increases, monitoring measures, restrictions or penalties may be applied.
The chargeback ratio is a metric that measures the relationship between disputes and a merchant’s transaction activity. It is a relevant indicator because it helps identify trends and detect a potential increase in the level of risk associated with transactions.
It is calculated by dividing the total number of chargebacks by the total number of transactions and multiplying the result by 100 to obtain a percentage. It is important that both metrics correspond to the same time period, whether one month, three months or one year.
However, a universal percentage should not be used to determine whether or not a merchant is at risk. Criteria, methodologies and monitoring programmes may vary depending on the scheme, market and acquirer.
In addition, monitoring only the overall ratio can hide important information. A more complete analysis should segment disputes by reason, product/service, country, payment method, channel, transaction type, device, source of fraud, among other factors. This allows the merchant to identify the root cause rather than simply reacting to the number of chargebacks.
Not all chargebacks can be prevented, but a good prevention strategy can help reduce avoidable disputes and detect higher-risk transactions.
Here are some key recommendations:
If chargebacks are already part of your day-to-day business, you know that it is not always easy to identify why they occur or how to act when they arise. The right payment platform can help you both prevent them and manage them more efficiently when they occur.
