About FraudBlock Fraud Prevention

The app automatically cancels 'high-risk' orders, send a cancellation confirmation to the customer (optional), restocks the inventory, and refunds/voids the customer's payment (if any).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. 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/refund, preventing any chargebacks. Automatically deal with fraudulent orders Re-stock inventory - when an order is canceled, FraudBlock restocks the items Automatic refunds - automatically refund/void the customer's payment Optionally send an email notification to the customer and/or the store admin Saves you from accidentally fulfilling fraudulent orders & chargebacks Show more Show less

Great app and great customer service! Definitely recommend using it!

— DigiPax

Very good app for blocking unacceptable customers

— Modaps International

Works flawlessly. "Automatic refunds - automatically refund/void the customer's payment" If you get hit with chargebacks, this is a must. While shopify will block any high risk order anyway, this fraud filter cancels the payment so you don't get a chargeback. It also emails the customer on the email they checked out with to inform them its cancelled. Very important if you sell digital items. This...

— Lizosoft Ltd

Perfect! I had questions during configuration and was guided through the personalization of customer emails. Thank you very much for your patience. The application does the job. Great.

Lightning fast customer support and super helpful with customer support ideas for contacting customers

— Yana

Very easy to setup, and complete peace of mind with it automatically blocking fraud orders. We were slow to respond to a high risk order placed on a weekend when we were away prior to using this app and had issues with Shopify payments. We've had no such problems since. More than satisfied and worth the money.

— The Jewellery Stop

App does what it says it does. Works flawlessly, super fast. Does not affect my store at all in anyway. Highly recommended!

— MyDiscounts.ca

I am loving the app because it helps us eliminate the fraud with no hassle plus the chat customer support is superb!

— Dream Controller

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!

— Skeie's Jewelers

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 using "No Fraud Fraud Protection", has everything I need and customer service is friendly. You can ***only*** get the Blacklist option via request. And even after request there is no convenient button to use so you always have to use the link they give you. Pretty basic need for a "fraud app", but no - they don't have it

— Breethe Activewear

FraudBlock Fraud Prevention will cancel the order and refund the customer but with 3rd party fulfillment networks that fulfill immediately after the order is placed, doesn't detect. I lost $3,000+ depending on this app to do this job when I should have done my own due diligence.

— Gilgamesh

i used this app for last 1.5 months and found this app blocks all highrisk orders and cancels the orders but will sometimes not refund the amount, and later on you will be issued with a chargeback of additional $25 from bank. The funniest part is if we contact the customer service they will say everything is all good from their side its issue of the shopify app in converting the currency and will...

— COOLJOULSS

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!

— QueenBeast

Its only good for one Option. Auto refund high risk Orders. In my Opinion this Option should be integrated in ShopifyPayments.

— Peer Online Shop

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.

— Spyra EU

Orders from potential fraudsters are automatically cancelled and refunded. The app is great! The support is always available and very helpful. We are now very well protected against fraudsters and annoying chargebacks.
