About Bad Customer

Bad Customer helps you avoid shipping goods to customers who have a habit of charging back their purchases or make excessive refund requests. We say enough is enough. Bad Customer isn't like other anti-fraud tools. Most anti-fraud tools use algorithms to try to look for suspicious activity. We think the solution is much less complicated; we identify the "bad customers" by looking at their chargeback history with other sites. Identifies customers who have charged back on other sites. Flag orders to PO Boxes or when billing/shipping are in different states. Flag orders from customers who create multiple accounts. Show more Show less

Seems to be working great. It would be nice if I could define custom attribute & value for blocklist or at least we had a phone number block list alongside email blocklist. I would like to block customer by email as well as phone number.

Would be a great app if you could search emails or addresses after you input them. Our list is long and it's a pain to have to look through the whole thing to find one customer to see why they are blocked. Please add a search feature! Thanks for adding the feature so fast!

— WOLFpak

Exactly what I needed: I add a customer's email or address in the black list and I get notified by email when the customer makes an order! Great!

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 chargebac...

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

— Incredible Inventions

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 ex...

— My Righteous Apparel

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 a...

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

— HIDDEN CULT

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.

— SideShaper

Remove a note from a customer's order for no reason. Idk if it was a glitch but because the app auto removed the customer's note even though they were not flagged and we ended up missing the note asking us to hold their order and ended up getting a chargeback from the customer cause we sell perishable products and the customer was not able to be there to receive their order and blamed us for not s...

I used this app to help stop repeat offenders from being able to make purchases, loaded all the information required (address and zip) for every previous chargeback customer and in the 12 days it has been installed we have had 3 orders come in from previous chargeback customers go through without being tagged. Further more we have had new chargeback customers in that week and when you use this app...

— Ride Out Supply

Would be a good app if it actually blocked bad customers. All it does is email an alert which is easy to miss prior to processing the order.

— Tech Instrumentation

I have downloaded this app twice and it still won't load. it gets to a blank screen and then nothing after that

— shadezhut llc

the block list I thought would block people from actually ordering but it doesn't. it just adds them to a list to show the orders placed by the flagged clients.
