// checkout extensions
Checkout extensions are the official way to customize the Shopify Plus checkout without breaking upgrades. I build extensions that increase average order value, collect data and personalize the payment experience — all within Shopify's secure sandbox.
// context
Checkout extensions are UI components rendered inside Shopify's checkout using the Checkout UI Extensions API. Unlike checkout.liquid (deprecated), they run in a sandbox, are upgrade-safe and work on all devices. This is the future of custom checkout.
// capabilities
[ upsells ]
Complementary products at checkout with cart-based logic. Average 8-15% increase in order value.
[ custom fields ]
Extra fields at checkout: tax ID, delivery instructions, gift message, special notes. Real-time validation.
[ payment ]
Reorder, hide or rename payment methods based on cart contents, location or customer tags.
[ post-purchase ]
One-click post-purchase offers. Satisfaction surveys. Cross-sell before the thank you page.
