Reducing fraud without hurting conversion

Fraud engines that block too much are worse than fraud engines that block too little. Here's how we balance both with machine learning.

Most fraud tools over-block. MondialPay's fraud engine is trained on billions of transactions to find the optimal threshold for each merchant, maximising approvals while staying below your chargeback target.

The conversion/fraud tradeoff

For most businesses, the cost of a declined good customer is 2-5x the cost of a chargeback. Our default configuration reflects that.
