About this gig
Lost custom discount, shipping or payment logic when Shopify Scripts were retired? Need your Plus checkout to do something the settings can't? I'm a senior Shopify Plus developer with 13 years in e-commerce, and I build checkout UI extensions and Shopify Functions the way Shopify now requires.
What I build:
- Discount Functions: tiered, bundle, buy X get Y, customer-tag and volume discounts
- Shipping and payment rules: hide, rename or reorder methods by cart, customer or location
- Checkout validation: order limits, address and product rules
- Checkout UI extensions: custom fields, banners, upsells and trust blocks on checkout, thank you and order status pages
How I work:
- I review your old Scripts or requirements first and confirm what Functions can and can't do
- Built as a custom app on your store and tested with test orders before going live
- You get the source code, setup notes and a short screen recording showing how it works
Not included: Shopify plan or app fees, third-party apps, or design work beyond Shopify's checkout branding settings.
Please message me with your store URL and what your checkout needs to do before ordering.
Respect third-party rights

Senior Shopify Plus developer with 13 years in web and e-commerce. I've spent recent years working inside Shopify Plus agencies on large UK, EU and US stores, so I deliver clean, tested code on deadline.
I build: checkout UI extensions and Shopify Functions (discount, shipping and payment rules, Scripts migration), Online Store 2.0 sections and theme rebuilds, store redesigns, WooCommerce to Shopify migrations, speed and bug fixes.
Every job is tested before delivery, with clear handover notes. Message me before ordering and I'll confirm the scope and timeline.

FAQ
Do I need Shopify Plus?
Checkout UI extensions on the information, shipping and payment steps, and custom apps that use Shopify Functions, need Shopify Plus. Thank you and order status page extensions work on all plans. Message me and I'll confirm what's possible on your plan.
My old Shopify Scripts stopped working. Can you rebuild them?
Yes. Send me your old Script code or describe what it did, and I'll rebuild the logic as Shopify Functions. Most line item, shipping and payment Scripts have a Functions equivalent, and I'll tell you upfront if one doesn't.
Will this slow down my checkout?
No. Functions run on Shopify's own infrastructure and checkout UI extensions run in Shopify's sandbox, so they're designed to keep checkout fast.
What do you need to start?
Collaborator or staff access with permission to develop apps, your store URL, and either your old Script code or a clear description of the rules you need.
Do I own the code?
Yes. You get the full source code and setup notes with the delivery.
Can you also style my checkout?
Yes, as an extra: colors, fonts and layout using Shopify's checkout branding settings.
