Hi Jshoplist,

Entering a bill or expense transactions add the quantity on hand of your items. You'll want to edit the quantity of the items. Then, enter an invoice so it will deduct from your product and services quantity on hand.

Here's how:

1. Click the Gear icon.
2. Select Product and Services.
3. Select the item, click Edit under the Action column. 
4. Change the Quantity on Hand value.
5. Click Save and close. 

Moving forward, create an invoice if you want to be deducted from your product and services quantity on hand. Please check this article for the detailed steps: Create Invoices in QuickBooks Online. 

You can also track inventory that you're donating, please check this article for more information: Track Donated Inventory.

Feel me in if you have any other concerns. I'm always right here to help.
