A bundle sold, but a component was already out of stock. Now you're refunding, apologizing, or scrambling to a supplier. Shopify's bundle availability ignores components that are untracked or set to continue selling, and third-party bundle syncs can drift. Bundle Guard scans every fixed bundle, shows how many are truly buildable from component stock, flags the risky configurations, and emails you the moment a bundle becomes unfulfillable. Read-only: it changes nothing in your store.

• See true buildable stock for every fixed bundle
• Flags untracked and continue-selling components — the silent oversell holes
• Alerts when a component stockout makes a bundle unfulfillable
• Detects drift between bundle and component availability
• Fully read-only — no theme changes, no store writes, no customer data
