The support staff was extremely helpful. They pointed me to all the right settings that I need to Manually Capture Payments on high risk orders. Thanks again!

Wow, simply wow! This app can prevent you from fraud. It cancels the order after the order is done & PREVENTS THE CUSTOMERS PAYMENT so you don't pay the payment provider fees. Nick from the Development team also helped us super quickly with some custom rules right from the start for a much lower price than we expected, so we were able to blacklist our main troll customers right in the beginning - I recommend to write to the support before you install the app if you also have this need. :) If I could I would grant 7 stars and more with my review.

This app worked flawlessly to immediately block orders that were marked as fraudulent or potentially fraudulent. Then you can decide how you want to proceed once you review the order details. It really helps keep the orders clean!

We had big problems with fraudsters in the past. After testing several apps, we came across FraudBlock. Through FraudBlock's support, we were able to create rules according to our wishes. We now have the issue of frauds under control. Great app, easy to use and excellent support. I would always recommend it.

This app has helped us so much since we installed it on our Shopify store! We had several fraudulent orders coming in each month, and since downloading, FraudBlock has caught each one and cancelled it for us, saving us so much time, worry, and money due to chargebacks that could have been prevented. The developer was also extremely helpful and friendly with quick replies both times we reached out for help. 10/10!
