SMART Checkout Rules, by E-TRADE PARTNER, is a free Built for Shopify app that gives merchants conditional control over the checkout. Rather than adding upsells, it manages how payment methods, shipping options, and discounts behave based on flexible rules.
Key features
- Payment and shipping control: hide, block, sort, or rename payment methods and shipping options.
- Conditional rules: trigger logic by country, customer tag, cart value, product, or discount.
- Risk management: block high-risk orders or specific methods like COD, PayPal, or credit card.
- B2B and international: streamline checkout flows for B2B, international, or rule-based segments.
- Smart logic: apply shipping or discount rules by cart total, tag, or delivery method.
Pricing and rating
SMART Checkout Rules is completely free. It is available in many languages — including English, German, Spanish, French, Japanese, Italian, and more — and is built on Shopify Functions.
It holds a 5.0 rating from over 420 reviews, with 98% at five stars. Merchants credit it with solving Shopify's checkout limitations and praise quick, professional support for setting up rules like renaming payment options or adding conditions.
Pitfalls
This is a checkout-rules app, not an upsell tool — it controls payment, shipping, and discount logic but does not add upsells, content blocks, or branding to lift AOV. It relies on Shopify Functions, and complex setups may need a quick hand from support.
Conclusion
SMART Checkout Rules is an outstanding, genuinely free way to take control of checkout payment and shipping options, with a strong rules engine and excellent support. It pairs well with a dedicated upsell app: use it for checkout control, and add an upsell tool separately when AOV growth is the goal.
