bundleinventory

To track inventory at the bundle level (i.e., the total number of complete bundles available), you must use a SKU-based bundle. The system will then manage the stock of the bundle as a single unit.

If you do not need to track inventory at the bundle level and instead want to rely solely on the inventory of the individual product options within the bundle, then you do not need to use a SKU-based bundle. This is the approach used for SKU-less bundles.
