FAQ
Do I need Shopify Plus?
For checkout page (info/shipping/payment) customization, yes. Thank You & Order Status extensions work on ALL Shopify plans.
Is this future-proof after the checkout.liquid deprecation?
Yes. Checkout UI Extensions are Shopify's official, supported API — unlike deprecated checkout.liquid.
Can you migrate my old checkout.liquid customizations?
Yes — migration is a specialty. Send me your current setup for a quote.
Will I own the code?
100%. Full source code and rights are transferred on delivery.
Do you handle the backend/hosting for advanced features?
Yes. I build hosted Laravel/Node backends with Admin API and app proxy (Premium package).
How is the app installed — do I need App Store approval?
No. It's installed via custom distribution — a private app for your store only.
