Hello @FactoryBlinds,
Thank you for posting here in the Community. I'm here to help you edit the dropdown options of these invoice columns.
These values are preset data you can add using the Enterprise version. You'll need to review the custom fields you've set up for your items to update the dropdown.
Here are some screenshots for your visual reference:
In case you need the steps, here's how:
- Go to the Lists menu and select Item List.
- Double-click any item on the list to open and edit it.
- Select Custom Fields, then select Define Fields.
- Edit the custom fields.
- Hit OK to save.
I've attached an article you can use if you want to import custom form templates in QuickBooks: Use and customize form templates.
Leave me a comment below if you have other concerns about entering sales form templates or editing custom fields. I'll be glad to help you some more.
