Thank you for the reply but from a quick overview this doesn't truly solve my problem. First, we are using QuickBooks Desktop Pro (should have established that initially).

Let me try to explain it differently:

• Let's call the company ACME. 
  ACME is setup with Accounts Payable as the first and last name - this is where invoices would be sent by default. 
• A monthly invoice for a recurring service is sent to Accounts Payable - this currently works fine.
• We have now also provided services for two separate divisions of ACME each led by two different representatives: John Smith & Jane Lu. Invoices for these services need to be sent independently to the representatives - one addressed to John and one addressed to Jane.  
• We want to be able to monitor customer balances and perform company wide customer reports (aging for example) inclusive of all invoices sent to ACME - this would include invoices sent to Accounts Payable, John Smith and Jane Lu. 
• John and Jane are both entered into QuickBooks as Contacts with the Customer Information screen:
  

Is there a way when creating an invoice to select which contact the invoices should be sent to? This would result in proper addressing but still attribute the invoices to the proper Customer Account within QuickBooks. 

Thank you!
