Guides for stores that outgrew the app store.

What broke after the 2026 Shopify deadlines, how we rebuilt it, and what to check on your own store. Written from production systems, not docs.

Need this built, not just explained? Tell us what's manual, what's breaking, what Shopify won't do. One email is enough to start. We reply within one business day with questions or a plan.
