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.
