Out of stock customizable bundles

Have this strange situation where the two parts to a customized bundle are in stock and show in checkout but the bundle itself is marked as sold out. To be clear it still gets to proceed to checkout. Is this a bug or am I missing some details?

Hey @DanielPatricio - thanks for reaching out!

This is likely tied to how customized bundles are handled versus fixed bundles. For fixed bundles, Shopify maintains sellable quantity on the parent bundle variant based on component inventory. For customized bundles using cart transforms, the parent bundle line can still have its own availability/display state, while the component lines are checked in cart/checkout if that makes sense.

So if the components are in stock and checkout can still proceed, this may be the cart UI reading the parent bundle variant as sold out, while checkout validation is correctly validating the components. I’d check that the parent variant is marked with requiresComponents: true, especially if this is in POS, since that’s required for complete cart transform support there.

Hope this helps, but let me know if I can clarify anything on our end here.
