Edit email address that appears on invoice

Edit email address that appears on invoice

Hi

How do I change the email address that appears on invoices, it is showing the email address that i used to sign up to zoho with but I want to change it to another email address that we use for accounts.

also is there a way to edit the position of a field on a template - for example the one i am using is showing my business details on the left of the page so how do I move it to the right of the page.? is that even possible?
