Head Office Accounting directs Invoices and Credit Notes raised at Branch level to be recorded against the Head Office Account rather than the issuing Branch. However, you can ignore this option and still direct the Invoice to the Branch Office.

See:

Managing Customer Master Records‍ 

Set up the accounts as outlined in Managing Customer Master Records, making the following changes.

• Head Office Account: In the Account Settings tab, tick Head Office Account to add it to an internal list of Head Office Accounts. Then when setting up the Branch Accounts, it will be available for selection.
• Branch Accounts: When setting up the Branch or Subsidiary Accounts, the Invoices and Credit Notes raised need to be recorded in the Head Office Account Sales System. In the Accounts Settings tab, tick Invoice Head Office and select the appropriate Head Office Account from the dropdown.

Sales Orders can be created against the branch account and once the Sales Order is delivered, it will be invoiced automatically to the head office.

Only Sales Item Invoices and Sales Item Credit Notes , including Recurring Sales Invoices‍ can be directed to the Head Office Account. Batch Invoices and Credit Notes will still be directed to the Branch or Subsidiary Account.  

In the branch office, raise an Invoice or Credit Note as normal. The system will recognise that the account is linked to a head office and ask if you want to invoice the head office instead. 

• Click OK to direct this Invoice to Head Office, whereupon the Account Code will change to that of the Head Office Account.  
• Click Cancel if you want to ignore this option and just want to invoice the Branch Office as normal.
