Invoice Templates:
Invoices are generated using the default invoice templates. Web Suite gives you the ability to change the invoice template here before printing or emailing it to the client. Click 
to open the Invoice Selection screen where you can select and preview invoice templates.
Typically, this change is only for the selected client. However, if you mark the check box on the left and assign a different template to an invoice here, you are prompted to permanently change the invoice template for all the projects associated with this client.
