I appreciate you joining the conversation, @NateP.

The inventory adjustment will ensure you're correctly tracking your items in QuickBooks. As long as you've posted the adjustment to their proper accounts, your inventory status report will show accurate tracking of your inventory quantities.

To ensure you track your COGS correctly, you can check out this article for more information: Adjust your inventory quantity or value in QuickBooks Desktop.

However, if you need to offset your adjustment, I'd recommend reaching out to your accountant first. This way, your accountant can decide which accounts to use to properly track your inventory. 

If you have additional concerns, let me know by leaving a comment. I'll be ready to pop-in and help.
