Inventory Sync
Real-time stock tracking synced across your Shopify locations.
Overselling kills trust. Selling a bundle of 4 products is great — until one goes out of stock and you're still taking orders. Manual inventory tracking doesn't scale, and overselling destroys customer trust.
How it works
Get started in 4 steps
01
Install the theme extension
One-click setup, no code editing.
02
Inventory syncs automatically
Shopify webhook fires on every inventory change.
03
Customer buys a bundle
All component stock adjusts in real-time.
04
Order cancelled?
Stock restores automatically, bundle availability recalculates.
Inventory that manages itself.

Smart availability
Bundle quantity equals the minimum number of complete bundles you can make from all components. If you need 2x Product A (100 in stock) and 1x Product B (30 in stock), you have 30 bundles available. Always accurate, always up to date.

Real-time
Webhook-powered sync
Subscribes to Shopify's inventory_levels/update webhook. Fires immediately on any change — manual adjustment, POS sale, or another app updating stock. Only active when you have single-SKU bundles, so there's zero overhead otherwise.

Three handling modes
Show All keeps out-of-stock products visible. Hide Unavailable removes zero-stock products from the bundle. Prevent Purchase blocks adding products when stock hits zero. Plus a third-party inventory toggle for external systems like Brightpearl.
