I will migrate your shopify checkout liquid to checkout extensibility
Aditya V Singh
About this gig
On August 26, 2026 Shopify permanently removes checkout.liquid, Additional Scripts and Shopify Scripts from every non-Plus store. Anything still sitting in those fields stops firing. Conversion tracking breaks, upsells disappear, and there is no rollback.
I migrate your store before that happens.
WHAT I DO
Audit every legacy customization on your Checkout, Thank You and Order Status pages
Rebuild conversion tracking as Web Pixels in Customer Events (GA4, Meta CAPI, TikTok, Klaviyo)
Rebuild upsells, trust badges, custom messaging and loyalty prompts as Checkout UI Extensions
Port discount, shipping and payment logic to Shopify Functions
Verify every event fires with matching values against your pre-migration baseline
WHY ME
Webneco Infotech, a 15 developer team that has been building on Shopify since 2016. I work on a duplicate theme and a preview checkout first, so your live store is never touched until you approve.
You get a before and after tracking report, so you can prove nothing was lost.
Send me your store URL and I will tell you exactly what breaks on August 26.

FAQ
How do I know if my store is affected?
Open Settings then Checkout and look for Additional Scripts, then check your theme for a checkout.liquid file. If either has content in it, you are affected. Send me your store URL and I will check at no cost.
Will my live store go down during the migration?
No. I build and test on a duplicate theme against a preview checkout. Nothing reaches your live store until you have reviewed and approved the preview.
What if my tracking numbers change after the migration?
I record your current event values as a baseline before touching anything, then compare after. Any mismatch gets fixed inside the revision window at no extra charge.
What happens if I miss the August 26 deadline?
Shopify auto-upgrades your store and silently drops the legacy code. The store keeps selling, but your tracking and checkout customizations are gone. Rebuilding after the fact costs more than migrating now.
