On August 26, 2026 Shopify shuts off the legacy Thank you and Order status pages, checkout ScriptTags, and the Additional scripts box for non-Plus stores. Tracking pixels, upsells, and custom scripts wired to the old system stop working. CheckoutProof reads your checkout profile's upgrade status, classifies legacy scripts, scores your readiness, and maps each finding to its platform-approved replacement: Web Pixels, Checkout UI Extensions, or native integrations. It never accesses customer data.

• Readiness score with a countdown to your store's shutoff date
• Checks whether your new Thank you and Order status pages are live
• Classifies ScriptTags by where they run and what breaks on the deadline
• Finds legacy tracking scripts and names the Web Pixel replacement for each
• Guided manual checklist for the surfaces no API can read
