# Discrepancy between the received quantity and the inventory quantity for a purchase order

## Problem

Items were received, but the inventory does not account for all of them.

## Solution

> [!NOTE]
> **Note:** Depending on your account's configuration, you might see one or more of the following:
> 
> - *Items and Pricing* instead of *Pricebook*.
> - *Customer* instead of *Homeowner*.
> - *Procurement* instead of *Inventory*.
> 
> The names are different, but everything works the same way. For more, see [Commercial Personalization Platform - FAQ](https://help.servicetitan.com/commercial/docs/commercial-personalization-platform-faq).

### Discrepancy between the received quantity and the inventory quantity for a purchase order

A discrepancy in the received and inventory quantities is likely because the item was not active for inventory tracking when the PO was created. To confirm this:

1. In the main navigation menu, click **Pricebook.**

2. In the left side menu, click either **Materials** or **Equipment**.

3. Search for the item and select the *Actions* icon on the right side of the item row.

4. Click **View/Edit Materials** or **View/Edit Equipment**

5. Click the Inventory Settings tab

6. Review the date inventory tracking was enabled. If it was enabled after the PO creation date, you need to [create an inventory adjustment](/commercial/docs/create-edit-and-copy-inventory-adjustments#create-an-inventory-adjustment) manually.
