Shopify checkout customization rebuild: $2k–$10k per shop, 4–8 weeks for complex Scripts
Created 2026-05-22
Claim: Custom Shopify Function migrations (rebuilds of checkout.liquid / Scripts customizations as Checkout UI Extensions) typically cost $2,000–$10,000 per shop depending on logic complexity (SANOMADS, 2026). "A complex Scripts setup takes 4-8 weeks to migrate" (Revize.app, 2026).

Confidence: Industry-consensus.
Per Shopify Help Center, unmigrated customizations "will be lost" in the January 2026 auto-upgrade. This is not a "consider migrating" recommendation — it's a "your code will be deleted on this date" event. See Shopify checkout.liquid sunset (Aug 2024 → Aug 2025 → June 30 2026) — unmigrated customizations will be DELETED for the full timeline.
