Inventory cost adjusting automatically

Thanks for visiting the Community, @freefallbrewery. Selecting "Yes" to the pop-up message can affect your cost from the previous parts. 

I'd recommend you run the Inventory Valuation Summary report first and look for the adjusted items to make sure everything looks good. Here's how: 

1. Select Reports, then click Inventory.
2. Select the Inventory Valuation Summary, then set the dates to All.
3. Double-click the item in question. 

Should you need to make adjustments, follow the steps outlined in this article: Adjust your inventory quantity or value in QuickBooks Desktop.

To bring back the pop-up message again, follow the steps below: 

1. Go to the Edit menu, then select Preferences.
2. Click General in My Preferences tab. 
3. Check the Inventory and Purchase Orders are Active box. 

The next time you do it, you should see the prompt. Ensure to select "No" moving forward.
