How is inventory managed for bundles and their child items?

On Simple Bundles, inventory for both parent bundles and individual child items is automatically tracked and updated, ensuring you never oversell.

How inventory tracking works

Inventory is calculated based on the lowest-stocked item in the bundle. If one item runs out, the whole bundle will be marked as sold out. You can check inventory for both individual items and bundles inside the Simple Bundles app. Everything stays in sync with Shopify, so your storefront always reflects the correct inventory number.

When a customer buys a bundle, each child item is deducted from stock. The bundle inventory updates too, and you’ll see the changes in both Simple Bundles and Shopify’s inventory tab. If you adjust stock manually, that also gets reflected across both platforms.

Automatically trigger inventory sync for all bundles

If you've updated products in a bundle or changed inventory settings in Shopify, your inventory quantities may go out of sync. In this case, you can manually trigger a sync across all of your bundles, by going into your Settings page > Bundle inventory section and clicking on Resync all bundle quantities.
