Shopify checkout extensibility, Thank you page upgrades and tracking recovery
Shopify has retired checkout.liquid, Additional scripts and script tags on the checkout, Thank you and Order status pages. We rebuild what broke (conversion tracking, post-purchase content, custom checkout logic) with the tools Shopify supports now: pixels, checkout UI extensions and Functions.

Tracking and Thank you page recovery
A fixed-scope job for stores whose tracking or Thank you page content broke with the upgrade. It works on every Shopify plan.
What we do
- Audit which pixels, tags and apps your store used before the upgrade and what runs now
- Reconnect purchase tracking through official channel apps (Google & YouTube, Facebook & Instagram and others) where they exist
- Build custom pixels for the rest, including GTM, affiliate and analytics tools
- Remove old code so purchases aren't counted twice
- Rebuild Thank you and Order status content (surveys, messages, offers) as app blocks
What you get
- Every conversion tool checked with a real test order
- A short handover document listing each pixel and what it sends
- Consent settings that match your cookie banner
Fixed price, quoted after we review your store and the tools you track with.
Checkout UI extensions for Shopify Plus
On Shopify Plus, apps can extend the Information, Shipping and Payment steps. We build custom checkout UI extensions and Functions when an App Store app doesn't fit.
- 01
Custom fields such as delivery notes, PO numbers or gift messages
- 02
Banners, trust content and upsells inside checkout
- 03
Validation rules backed by your own data
- 04
Discount, delivery and payment logic with Shopify Functions, replacing old Shopify Scripts
Moving off legacy customer accounts
If your account pages were customized in Liquid, those changes won't carry over when you upgrade to the new customer accounts. We rebuild what you still need, so the upgrade doesn't take features away from your customers.
- 01
Audit of your customers templates, account apps, Flow workflows and customer segments that depend on legacy accounts
- 02
App Store app blocks where an existing app does the job
- 03
Custom customer account UI extensions on the Order index, Order status and Profile pages, or as new full pages
- 04
Theme header updated with the shopify-account component, and a test plan before you upgrade
- 05
Multipass replaced with your own identity provider and single sign-on (Shopify Plus)

Checkout extensibility questions
No. App pixels, custom pixels and app blocks on the Thank you and Order status pages work on every plan. Plus is only needed for extensions inside the Information, Shipping and Payment steps and for custom apps that contain Functions.
Usually the outcome, not the old code. Tracking is rebuilt with pixels, and content with app blocks. Anything that depended on changing the checkout page with scripts has to be rebuilt the supported way, and we tell you upfront if something isn't possible on your plan.
No. Conversions that weren't tracked while the tags were broken can't be recovered. Once the new setup is live, tracking works from that point on.
A collaborator account with the permissions needed for settings, customer events and apps. You don't need to share your owner login.
After a quick review of your store and the tools you use, we quote a fixed price for the agreed scope, so there are no hourly surprises.
Yes. We list what your legacy account pages do today, replace what we can with existing apps, and build the rest as customer account UI extensions. Liquid changes to the old account templates don't carry over when you upgrade, so this is best done before the upgrade or any theme change.
