QB Online doesn't have the ability to create A/R sub-accounts so you will need to find a new way to track this if you continue with QB Online.  This is a common complaint with QB Online because A/R sub-accounts were a very useful feature in Desktop.  I would suggest creating tags that match your A/R sub-accounts from Desktop, i.e. "1101B-01 Real Estate - Bourne" and assign the appropriate tag to each invoice and credit memo.  You can run a Transaction List by Tag Group report and filter by invoice and credit memo to see the outstanding balance similar to your A/R sub-accounts.  Not sure if that would work for your but that's the best suggestion I can think of.
