Wonder Flavours

We had an issue with some customers using US forwarding addresses and then charging back once they received their order. Bad Customer now tags orders when bill-to and ship-to addresses are in different states (or countries). Now we get a heads up and can contact the customer to verify their order, their payment, and their identity to ensure it's not fraud and that we can fight any future chargeback.

Incredible Inventions

Has found a few potentially bad customers, but what I really like is the quantity limit setting to flag orders with unusually high quantities.

My Righteous Apparel

I like that this app monitors for problem customers from multiple databases at the time the order is placed. By adding to my own blocked list, this app helps me keep track of customers I don't want to sell to (Multiple returns, too much drama, one-star review because of the post office, etc). The blocked list just reminds you. You can still process the order if you choose to. Excellent app with excellent support. Highly recommended.


Definitely a clever approach to fraud detection. Great app! Our Shopify store syncs with our warehouse automatically, so even if we did notice something that seemed suspicious, the warehouse had usually already packed and shipped it. We were able to configure our 3PL to ignore orders with the bc_warning tag so they didn't automatically ship and can just remove the tag if we want to take the risk and ship it anyway.


Great, simple app. Installed it a few days ago and has already saved me from fraudulent customers. Recommended :)


Does what it says. Sneaky customer had a new email and billing address but the same ship-to address and was trying to rip us off again. This app caught it and tagged the order.
