I'm switching to Books from Quickbooks. One of the great features in QB for my business was sub-contacts. This was used for instance to place children "under" their parents as client accounts for a music school. Transactions would be made in the child's account and would be linked to the parent to provide a view of ALL invoices and payments for parents who had more than one child. I'm sure this feature would be useful in other situations which require a sub-client.
This function should be added. Its very important function.

This is the same as "Allow child/parent contacts". The votes should be combined.
One of the reasons (amongst a few others) I can't commit to the change from Quickbooks online, although Zoho books is far superior (apart from reporting) !
