About Fraud Killer

Automatically cancel high-risk orders

Fraud Killer saves you from accidentally fulfilling fraudulent orders - automatically. We automatically cancel 'high-risk' orders, send a cancellation confirmation to the customer (optional), restock the inventory, and refund/void the customer's payment (if any). Save time by not having to manually comb through orders in your Shopify admin dashboard.

Why do I need Fraud Killer?

While Shopify automatically flags high-risk orders for you, it doesn't cancel them - you still have to go through your list of orders manually to find and cancel the ones flagged as 'high risk'. Fraud Killer takes care of this for you - automatically.

How does it work?

Whenever you receive a new order, we check it based on Shopify's fraud analysis. If it's a high risk-order, we automatically cancel it, refund/void the payment (if any), restock your inventory, and email a cancellation confirmation to you and the customer (optional).

Thank you so much for your review


This app doesn't work as described. Had a condition where fraud orders were being placed every 5-10 minutes and this app only caught 10% of them.. Should be deleted from the Shopify Store for false advertising.

Hi dear customer. Thank you for your review. Our app detect all fraudulent orders which are marked as fraud by Shopify system. If you have more fraudulent orders which was not detected by the app then they are not marked as fraudulent by Shopify. That’s not a app issue, just Shopify not marked as fraudulent
