# Inventory and dynamic bundles

You do not manage the inventory of a [dynamic bundle](https://doc.sitecore.com/xp/en/users/103/sitecore-experience-commerce/dynamic-bundles.html "Dynamic bundles"). The availability of a dynamic bundle is based on the availability of its constituent sellable items.

The following table illustrates three scenarios that impact the availability of the dynamic product bundle.

| Dynamic<br><br>Bundle | Constituent<br><br>Items | Default quantity | Inventory | Result |
| --- | --- | --- | --- | --- |
| 1 | A<br><br>B (optional)<br><br>C | 2<br><br>2<br><br>2 | 9<br><br>0<br><br>9 | Dynamic bundle 1 is available but the optional sellable item B is not. |
| 2 | A<br><br>B<br><br>C | 2<br><br>3<br><br>2 | 0<br><br>3<br><br>4 | Dynamic bundle 2 is not available because there are not enough of item A in stock. |
| 3 | A (upgradeable)<br><br>B<br><br>C | 1<br><br>2<br><br>3 | 1<br><br>3<br><br>3 | Dynamic bundle 3 is available even if the upgrade selections for item A are not all available. |

A dynamic bundle is *preorderable* or *backorderable* when at least one of its constituent sellable items is configured with the preorderable or backorderable option enabled. The availability date of a preorderable or backorderable bundle is based on the latest availability date of its preorderable or backorderable constituent items.

> [!note]
> Preorder and backorder functionality is not fully implemented in this release.

For example, a dynamic bundle that is composed of the following items is available for preorder and its availability date is December 2 2020.

- Sellable item A - Quantity: 2
- Sellable item B - Quantity: 0 - Inventory shows as preorderable, with an availability date of December 2, 2020.
- Sellable item C - Quantity 0 - Inventory shows as preorderable, with an availability date of June 2, 2020.
- Sellable item C - Quantity: 1
