I will migrate one checkout page from checkout liquid to checkout extensibility
Paul B.
About this gig
I will migrate shopify checkout.liquid to checkout extensibility and setup ga4 tracking
Shopify shut down checkout.liquid if your store relies on it for upsells, custom fields, or tracking, it's at risk of breaking. I migrate stores to Shopify's checkout extensibility framework properly, with zero data loss.
What I handle:
Checkout liquid fix and full migration to checkout extensibility
Custom checkout ui built with shopify functions
Web pixels api setup so GA4 and Meta pixel tracking survive the move
Ga4 tracking setup and validation post-migration
Branding api configuration to match your store
Shopify custom code and shopify liquid dev for anything checkout.liquid can't replace
Shopify migration support for Shopify Plus and standard plans
Shopify checkout fix for broken upsells, discounts, or shipping logic
Whether you need Shopify Plus dev-level work or a standard checkout extension rebuild, I'll get your checkout compliant and your tracking intact.
Order the package that fits your store, or message me first if you're unsure which tier to pick.

FAQ
Do I have to migrate off checkout.liquid?
Yes, Shopify has deprecated it in stages, and Shopify Scripts stop working entirely by mid-2026. Migration isn't optional anymore.
Will I lose my GA4/Meta pixel tracking data?
Not if it's done right, I rebuild your tracking using the Web Pixels API before removing the old scripts.
What's the difference between checkout UI extensions and Shopify Functions?
UI extensions handle the visual/front-end pieces (banners, upsells); Functions handle backend logic (discounts, shipping rules).
Do you work with Shopify Plus?
Yes, including custom checkout branding and advanced Functions work.
Will my current upsells/custom fields survive the migration?
I audit them first and rebuild anything that has a supported replacement.
How long does a full migration take?
Basic is 2 days for a single page; full checkout + tracking rebuild is 4-6 days depending on complexity.
Do you need my store access?
Yes, collaborator access to Shopify admin and checkout settings.
Can you fix a checkout that's already broken from a failed migration?
Yes, that falls under the checkout liquid fix service.
Is this just for Shopify Plus stores?
No, non-Plus stores also need to migrate before their August 2026 deadline.
Do you guarantee it'll pass Shopify's review?
I build to Shopify's current API standards, so compliance isn't in question, the checkout will function correctly once migrated.
