XV Checkout Customizer

Checkout rules for Shopify that stop fraud and bots, limit orders, and tidy up payment and shipping options — without ever risking a real sale.

• Stop bad orders. Block card-testing bots, known fraudsters, PO boxes and more, right inside Shopify checkout.
• Test before it's live. Every new rule starts in Test mode, so real customers are never affected by a mistake.
• Safe by default. If the app ever has a problem, customers can still check out.

Open the app from your Shopify admin.
