How Do I Change the Billing Address on my Invoices? ← Billing The billing address shown on your invoices is taken from the address listed under your head office.To change this, head to your company profile and edit your head office. If you have renamed this to something else, you will find your head office at the top of your list of offices. Amend the address details and click save when finished. NB: If you have expenses enabled, you will need to click next to go through to the second step before clicking save.
