We identify bad customers.

Bad Customer analyzes a customer's refund and chargeback history with other websites and warns you before you ship.

Automatic order tagging.

Set individual thresholds on when suspect orders should be tagged, and (optionally) configure your warehouse so you don't ship those orders.

Supports Private Block Lists

Block known problem customers by adding their email and street addresses to your private block list. We'll catch them if they try to order.

About Bad Customer

5/14/21 Update: Private Block Lists

You can now manually add problem customers to a private block list, so any future orders from them will be tagged for you to review or cancel. This was our most-requested feature since launch, so be sure to send us any feedback once you get a chance to try it out.

Identify problem customers before you ship.

Bad Customer helps you avoid shipping goods to customers who have a habit of charging back their purchases or making 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. If a lot of chargebacks or refunds are associated with that customer or the address they're sending their goods to, we'll warn you and you can decide whether you still want to ship the order or cancel it.

Banks profit from buyer fraud.

Ever wonder why it's so hard to win a dispute? Because credit card companies profit when their customers commit fraud against sellers. In fact, it's so common that the banks even have a name for it: Friendly Fraud. This is why credit card companies almost always side with their customer, even when evidence overwhelmingly favors the seller.

Smart Order Tagging

We've added a few other features too, like the ability to automatically tag orders where the total exceeds a certain amount or quantity of items, orders shipping to PO Boxes, or even where the bill-to and ship-to addresses are in different states. We're always evaluating new features and welcome suggestions.

Sellers helping other sellers.

Lots of apps and websites help customers avoid bad sellers, so we thought it was time an app came along that helped sellers avoid bad customers. By installing the Bad Customer app, you aren't just helping your own business prevent chargebacks -- you're also helping other sellers avoid them too.

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.

This is on purpose.

We found that when bad customers are aware they've been blocked, they will try different email addresses, misspell street names, or use a friend/neighbor's address to receive the goods in order to get around the block. By accepting the order, and tagging it so you can cancel it manually, the customer won't know why their order was canceled unless you tell them.

We hope you'll consider this perspective and consider revising your review, as the app is doing exactly what it aims to do -- detecting and tagging orders from bad customers.

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.
