Can you suspend or bar a problematic customer's account?

[StevetUK]

Is it possible to suspend a customer account or bar a customer from ordering based on, e.g. email address/telephone number?

We have a couple of problematic customers and while we've tried to resolve things amicably they are causing our business issues and we would like to prohibit them from dealing with us. This includes products that are tickets for events that we do not wish them to attend.

While we can cancel and refund, we lose the transaction fee and so it's costing us.

Can anyone assist?

Thanks Alok - the problem with Fraud Filter is that Shopify processing fees aren't recovered, so it's costly to the business. I'm looking for something that results in net zero cost to us.

Hi @StevetUK 

I am sorry to hear you are having these kinds of issues with some of your customers. As previously mentioned, the Shopify Fraud Filter app would be a great place to start. You are correct that using a fraud filtering app does not recover any transaction fees incurred by accepting payment and then refunding it back to the customer. This is because the Fraud Filter app is designed to block the customer from checking out, so no payment is processed at all. 

I would take a look at the available fraud protection and customer filter apps that are available in the app store and also look at enabling manual payment capture for the checkout until this issue is resolved. Manual payment capture will authorize the customer's payment method but does not process payment until approved by the merchant. This means you can review orders, cancel the necessary ones (avoiding those transaction fees), and capture payment for the remaining ones you plan on fulfilling.

If you are able to successfully block the customer using a fraud filter app, then you don't have to worry about the transaction fees for their orders.
