About this gig

I develop Shopify checkout extensibility and Shopify Functions the replacements for checkout.liquid and Scripts.


Use this gig if you need a custom checkout field, banner, upsell, discount function, or delivery rule that still passes Shopifys checkout review.


What I build

Checkout UI extensions (fields, banners, USPs, upsells, trust)

Shopify Functions (discounts, delivery, payment customisation)

Thank-you and order-status extensions (Plu and non-Plu)

A small app so the extension installs and updates


Shopify Plus

Checkout steps (information, shipping, payment) need Plus. Non-Plus stores: Thank You and Order Status only. I will not sell Plu features to a Basic plan.


How we work

Message me one paragraph: the rule (hide express under $50, gift message field, volume discount). I confirm Plus vs not, then you order.
