I will build shopify checkout extensions and shopify functions for shopify plus
Himel
Level 2
About this gig
Shopify Scripts stopped running on June 30, 2026, and checkout.liquid is gone. If your discounts, shipping rules or checkout customizations broke, I will rebuild them the modern way with Shopify Functions and Checkout UI Extensions.
I'm a Shopify app developer with 7+ years of coding experience. I build and run my own apps on the Shopify App Store, so I work with the Shopify checkout, Functions and APIs every day.
What I can build for you:
- Checkout UI extensions: custom fields, banners, trust badges, upsells, Thank you page blocks
- Shopify Functions: custom discounts, tiered and volume pricing, BOGO, bundles
- Shipping and payment customizations: hide, rename or reorder rates and methods
- Cart and checkout validation rules
- Shopify Scripts to Functions migration
- A custom Shopify app to manage it all from your admin
Why work with me:
- Clean, documented code that you fully own
- Tested on a development store before going live
- Fast replies and 7 days of free support after delivery
Note: checkout UI on the information, shipping and payment steps needs Shopify Plus.
Message me before ordering so I can confirm the scope for your store.

FAQ
Do I need Shopify Plus for this?
For checkout UI on the information, shipping and payment steps, and for custom apps that use Shopify Functions, yes. Thank you and Order status page blocks work on every plan. Not sure? Send me your plan and I'll tell you what's possible.
My Shopify Scripts stopped working. Can you replace them?
Yes. Send me the script code or describe what it did, and I'll rebuild the same logic as a Shopify Function for your discounts, shipping or payment methods, then test it on a development store before it goes live.
Will this slow down my checkout?
No. Shopify Functions run on Shopify's own servers in milliseconds, and checkout UI extensions are rendered natively by Shopify, so your checkout stays fast and secure.
Do I own the code?
Yes. You get the full source code for the app and extensions, deployed to your store. I can also push it to your GitHub repository.
What do you need from me to start?
Collaborator access to your store (or a development store), a clear description of what you want, and any existing Script code. I'll confirm the scope with you before I start.
Do you offer support after delivery?
Yes. You get 7 days of free bug fixes after delivery. For new features later, just send me a message.
