Shopify checkout rule guides
How to control what shows at your checkout — hide or rename payment methods, hide shipping by country or postcode, block PO boxes, and more. Each guide shows the native Shopify way, where it quietly breaks, and how to do it safely with a preview.
Checkout rules decide what a shopper actually sees at checkout — which shipping options and payment methods appear, and whether they can complete the order at all.
Shopify does some of this natively, through checkout customizations and Functions. Four things it does not do:
- No admin toggle for most cases
- No way to combine conditions
- No preview before a change is live
- Silent failure when a condition does not match
Every guide below covers one real case and answers the same three questions: how far Shopify's own settings get you, exactly where that stops, and how to do it with a rule you can preview first.
-
