How can I block or blacklist certain customers from placing orders?

Hi @BriBri

Dani here from Shopify.

First of all, welcome to Shopify! I hope you’re finding the migration process smooth, we’re here to help if you do have any questions at all!

As Brian suggested, the Fraud Filter app may work well for you! It’s a free Shopify developed app that can either automatically cancel certain orders, or alert you that a possible fraud order has been made. You can set a variety of custom filters to add extra protection to your store. Take a look at our help doc for more information on this app.

There are many additional third party fraud apps you could consider as well! A few that I found which you may be interested in are:

For future orders, you may want to consider our Fraud Protect program. With Fraud Protect, all eligible orders are protected from chargeback risk based on a custom percentage for your store. If a chargeback does come in on a protected order, Shopify will cover the chargeback cost and fees!

That’s really impressive that you have been online for 20+ years! I’m curious, what’s been your favourite thing about Shopify so far? And what advice would you give to someone just starting out in their online business venture?

All the best,

Dani
