Yeah, it’s not even your fault, but that’s unfortunately how things go in the cyber payments industry. Besides implementing security measures such as asking for ZIP code verification and CVV numbers, you should price your products to allow for something in the range of 1% chargebacks.

This free calculator from Kount will help you determine how much fraud can cost your business and estimate your margins based on the cost.
