Checkout Guard – Order Blocker for WooCommerce

Checkout Guard is a WooCommerce plugin that lets store owners block unwanted orders by setting up rules based on customer name and email. It’s designed to stop fraud, spam, and abusive customers at checkout — if a customer matches a blocked entry, they’re shown a denial message and prevented from completing their order.

The plugin provides a clean admin interface under WooCommerce where store owners can manage their list of blocked entries, each with optional notes and attribution showing which admin created the rule. The checkout denial message is fully customizable, giving store owners control over the experience when a blocked customer attempts to place an order.
