# How to Deactivate and Edit Vendors in Inventory

## Problem

You can't deactivate a vendor, and when attempting to add information to another vendor, you receive the following error message: *Action canceled - Object reference not set to an instance of an object*.

## Solution

To deactivate a vendor:

1. Go to the Inventory section in ServiceTitan.
2. Click the **Vendors** tab.
3. Find the vendor you wish to deactivate, click **Edit** to update vendor.
4. On the edit vendor screen, to the right of "*Vendor Details*" turn off the **Active** toggle to deactivate the vendor.

To edit a vendor:

1. Go to the Inventory section in ServiceTitan.
2. Click the **Vendors** tab.
3. Find the vendor you wish to edit, and add an extra character to their name.
4. Click the **Save** button.
5. After the property is saved, go back to the edit mode for the vendor and remove the extra character that you've added to the vendor name.

> [!NOTE]
> **Note:** If you receive the *Action canceled - Object reference not set to an instance of an object* error message when attempting to add information to a vendor, try adding an extra character to their name and saving the information. Then, go back and remove the extra character from the vendor name.

You have successfully deactivated a vendor and edited a vendor in ServiceTitan's Inventory system.
