Hi there, @adl, 

Thanks for letting me know the steps you’ve tried to help resolve your item notes concern.

I’ll share some information about saving item notes in QuickBooks Desktop (QBDT) Enterprise.

When you save notes to an item, it will automatically save to the Notes section on the Inventory Center. Here’s how to check the item notes:

1.    Go to the Inventory menu at the top.
2.    Select Inventory Center.
3.    Select the inventory item.
4.    Click the Notes section at the bottom and the notes will appear.

Please refer to the screenshot below to guide you through the steps. 

If you want to show the item notes when editing the item on the Item List, I’d suggest sending feedback to our Product Development Team. Let’s share with our engineers to help them implement this feature into future updates.  Here’s how:

1.    Go to the Help menu at the top.
2.    Select Send Feedback Online.
3.    Choose Product Suggestion.
4.    Click the Product Area drop-down.
5.    Input your suggestion.
6.    Click Send Feedback.

Your suggestion would be a great help to make entering and saving item notes better in QuickBooks Desktop.

If I can be of further assistance, I'm just a post away. I'm always here to help. Have a wonderful day, @adl!
