If your client has requested a change to the billing address on an invoice or asked to send the invoice to a completely different company, we recommend creating a new billing address under the client:
Go to the client's detail page.
Click on "+Add new billing address."
Then, go to the invoice you want to edit.
Click on the "Edit" button.
In the first invoicing step, change the current billing address to the new one.
Continue through the next steps and click on "Update."
