# Update an inventory item's quantity and cost

Update an inventory item when your stock quantity, category, description, or purchase cost changes.

### Update the item

1. From the left menu, open **Inventory**, then select **Items**.
2. Find the item you want to update.
3. Select the three-dot menu at the end of its row, then select **Edit**.
4. Update the **Item name**, **Description**, or **Category** if needed.
5. Under **Quantity**, enter the total number of units you now own.
6. Under **Asset cost**, enter the purchase cost of one unit.
7. Review the security-deposit and image settings.
8. Select **Save changes**.

### What happens next

Bundus returns to the inventory list and uses the updated total quantity when calculating availability. **Available Now** may be lower than **Total Owned** when units are already committed to bookings.

> **Rental prices use a separate screen:** select the item's three-dot menu and choose **View rates**. See [Create and manage rental rate periods](/help/inventory/manage-rental-rates.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bundus.gitbook.io/help/inventory/update-inventory-details.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
