Question -  Can I have 2 different logos and set up separate billing templates to select the invoice style to use.  


Answer - You can put one in as the Invoice logo and one as the statement logo and then reference them separately. Companyname-InvLogo.gif and Companyname-StmtLogo.gif will be the file names – you can then reference them in the invoice template. 

You will then be able to select the templates on the fly in the invoice screen.
