Hello lroth,
I’m here to share how adding a sub-account works in QuickBooks Online (QBO).
When adding a sub-account, the parent account must be the same category type. For example, if the sub-account is Other Current Assets account, the parent must also be an Other Current Assets account.
Here’s how to add a sub-account:
- Go to Accounting on the left pane.
- Click the New button at the top, then enter the needed details for the sub-account.
- Check the box next to Is sub-account.
- Select the parent account.
- Click Save and Close.
You can also take a look at this article for reference: How do I create a new account or subaccount in QuickBooks?
There you have it. I’d be glad to help if you have further questions while working in QBO. Enjoy your weekend.
