I was unable to import sub accounts in QBO. Is it possible to import sub accounts in QBO ?

Hello there, mubbasher.

Yes, you can import sub-accounts in QuickBooks Online. I'm here to share more information about it.

When importing (CSV) the accounts, ensure to add the sub-level account under the Account Name column. See the sample format below:

Once you're ready, follow these steps to start the import process:

1. From the Gear icon, select Import Data.
2. Choose Chart of Accounts, and then Browse.
3. Then, find and select the spreadsheet you saved.
4. Select Next.

To learn more about this process, check out the following articles:

Also, did you encounter an error while importing sub-accounts? Let me know so I can provide the solution that fits the error.

You can always get back to the thread. I'll be around to guide you.
