Blacklist Customer

Blacklist Customer is a Shopify app in the Fraud category. Customer Blacklist lets your rental business blacklist bad customers- those who've caused damage, chargebacks, theft or other issues. It also cross-references a customer's details against other orders (e.g. in a case a customer is trying to mask their identity with a fake name but same postal address). New order > the app checks the customer's name, email, phone, and address against your register > if there's a match, your staff get an alert before dispatching the order (so no false positives).

Open the Blacklist Customer listing in the Shopify App Store at apps.shopify.com/dress-blacklist, choose "Add app," and complete the Shopify install flow. After installation, you can configure Blacklist Customer from your Shopify admin under Apps.
