Ecommerce is booming—but so is fraud. Whether it’s friendly fraud, stolen credit cards, or subscription scams, merchants are constantly under threat. If you're not actively working on fraud prevention, you’re already behind. Chargebacks, in particular, can drain revenue, damage merchant accounts, and leave store owners frustrated and confused. Here's what you need to know about fraud prevention for ecommerce and how to protect your store from unnecessary losses.

Why Ecommerce Fraud Happens

Fraud in ecommerce occurs when someone makes a purchase using deceptive or unauthorized means. This includes:

• Friendly fraud: When a customer disputes a legitimate charge.
• Stolen credit cards: Unauthorized purchases made with stolen credentials.
• Chargeback abuse: Customers using chargebacks instead of asking for a refund.

Fraud is rising because online transactions are convenient, fast, and often anonymous. And as ecommerce grows, so do the opportunities for bad actors.

Chargebacks: The Merchant’s Nightmare

Chargebacks are one of the most common consequences of ecommerce fraud. They occur when a customer disputes a transaction with their bank. If the bank sides with the customer, the merchant loses both the product and the revenue.

Understanding the chargeback process is the first step in preventing them. Learn more about each stage in our detailed guide to chargeback dispute stages.

It’s important to understand the differences between a chargeback and a refund and chargebacks vs disputes. Knowing how to respond effectively, what counts as compelling evidence, and when to take action can greatly reduce your losses.
