Hey there, Anchor Caddie1.
The inventory quantity of an item won't be reduced if you create a non-posting transaction such as estimate/quote.
You might want to set a reorder point for the inventory item so QuickBooks will notify you if it has a low quantity moving forward.
- Click Lists at the top menu.
- Select Item List and double-click the item.
- In the Edit Item window, go to the INVENTORY INFORMATION section.
- Enter the Reorder Point and click OK.
Then, you can reorder the stocks by creating a bill. This will increase the inventory quantity of an item.
If you need any other assistance, feel free to post below. Thanks for your time and have a nice evening.
