When checkout says "Shipping not available", the customer can't pay. Gapscout reads your shipping setup and lists where that can happen: countries a zone forgets, carts heavier or pricier than your top rate, zero-weight products, products outside every rate in your markets or shipping profiles, unused carrier services. Shopify moves every store to market-driven shipping by July 2027: Gapscout checks both setups and can compare rates before and after. Read-only: it never changes your settings.

• Finds countries, weight bands and cart values that get no shipping rate
• Lists products that no rate covers in your markets or shipping profiles
• Flags zero-weight products, unused carrier services and unset locations
• Daily monitoring with in-app alerts when something new breaks
• Read-only: never edits your shipping settings and reads no customer data
