Thanks for joining this discussion, @courtajohns,

Allow me to join and share some insights on how to resolve this item concern.

At the moment, the option to change inventory to other item type is unavailable. Since you're not going to track stocks, you can create a new item for the products.

1. To do that, tap the Gear icon the choose Products and Services.
2. Click New then pick the type you want to use moving forward.
3. Fill out all the information about the item then press Save and close.

Then, you can replace the items on the sales transactions with the new item one by one. Here's how:

1. Go to the Gear icon again then Products and Services.
2. Find the inventory item then head to the Action column.
3. Tap the drop-down beside Edit then pick Run report.
   
4. All the entries related to the inventory are displayed on the report.
5. Click the entry to open, then change the item manually with the new one.
6. Make sure the amount is correct before saving.

Once everything is cleared, you can make an inventory adjustment to zero out the inventory quantity. This article will help you with the steps: Adjust inventory quantity on hand in QuickBooks Online

You can also make it inactive to remove it from the list of products. Just go to the Products and Services page then select Make inactive in the Action column.
