We need to be able to have a customer parent child chain.
eg. If I'm selling to ACME PTY LTD i would like them to be the parent customer but i might have two people that purchase from me from that company say John Dow and Jane Dow, they need to be able to have there own customer profiles with their individual contact information and record of their individual purchases, but then the invoices need to show at the parent customer level for payment.
