Hey there, Isdory. I'm here to provide insights about moving stocks in QuickBooks Online (QBO).
The option to move stocks is unavailable in the program. For now, I'd suggest looking for a third-party app that would help record the movement of your stocks in QuickBooks. Simply go to the Apps menu and select Find apps. Then, look for the app in the Search box.
Furthermore, creating a stock within a stock is also unsupported in QuickBooks. However, you can utilize the Bundle feature to group your stocks under one item. Here's how:
Go to Sales and select Products & services.
Click New.
Select Bundle, then enter the name of the stock.
Add the items under the Products/services included in the bundle section.
Click Save and close.
