Fraud Prevention

How to best protect against disputes and fraudulent payments.


In response to the elevated disputes faced by many merchants in the travel and entertainment industries due to COVID-19, Visa and MasterCard have issued guidelines for resolving them. These guidelines relate specifically to goods and services canceled directly due to a government order or prohibition.

For all industries, the best actions you can take are to proactively communicate with your customers and issue refunds where appropriate, especially when requested.

Disputes are an unfortunate aspect of accepting payments online and the best way to manage them is to prevent them from happening at all. An effective dispute and fraud prevention strategy uses a number of methods that are best suited for your business while keeping any customer burden - and losses - to a minimum.

Use the following information to create an effective disputes and fraud prevention strategy. Depending on the service you provide, the goods you sell, or how your business operates, certain methods may be more effective than others.

Collect As Much Payment Information As Possible

Some disputes are lost because only the minimum information was required during checkout. This makes it difficult (sometimes impossible) for QorCommerce or the card issuer to verify that the customer is legitimate. For instance, while a billing postal code is not always necessary to process a card payment, including it allows the payment to be verified by the card issuer. If verification fails, consider rejecting the payment as this may be an indication of fraud.

Using the QorCommerce payment tools and API ensures your integration is best equipped to provide relevant payment information, such as:

  • Customer name
  • Customer email address
  • CVC number
  • Full billing address and postal code
  • Shipping address (if different from billing address)

Effective Customer Communication

Clear and frequent contact with your customers can help prevent many of the reasons for disputes. By responding to issues and processing refunds or replacement orders quickly, your customers are far less likely to take the time to dispute a payment. Make your customer service contact information easy to find, keep customers updated throughout their order process, and provide updates about deliveries.


You should include a clear description of your refund and cancellation policies in your terms of service. You can require your users to agree to your terms of service in order to increase the likelihood that card issuers respect your policies in the event of a dispute.

  • In general, you should make your terms of service and policies easy to find on your website, and require customers to agree to them. Rather than simply linking to them during checkout, provide a full version of them on the checkout page or as a pop-up with a requirement to agree to them prior to submitting the order.

  • Card issuers can be very specific about how you present your policies. If you have a checkbox your customer must accept that only contains a link, it can be rejected as unsatisfactory evidence that your customer was aware of your policies. There must be reasonable evidence that your customer was presented with a full copy of your policies prior to their purchase.

  • When shipping physical goods to customers, use carriers and services that provide online tracking and delivery confirmation whenever possible. Provide this information to your customers as soon as it’s available (if you need to submit tracking information as dispute evidence, note that card issuers do not follow links so screenshots must be provided).

  • Use a recognizable name for your statement descriptor. This can be set or updated in your account settings and we recommend using your website domain or business name. This helps avoid customer confusion when they look at their statement. Statement descriptors are limited to between 5 and 22 characters. They must contain at least 5 letters and cannot use the special characters <, >, , ', or ".

  • Avoid using the same QorCommerce account for separate businesses. Each QorCommerce account should represent a single business, which allows for separate statement descriptors and contact information. If you need to process payments for multiple businesses, you can create additional accounts for each.

Avoiding Fraudulent Payments

A payment is considered fraudulent when the cardholder did not authorize it. Most fraudulent payments are made using stolen cards or card numbers. When a cardholder is notified that the payment has been made or they review their card statement, they contact their card issuer to dispute it.
