Tracking ROI & ROAS on B2B non-ecommerce website

[jebernier]

Hello,
My company has a B2B website and they do not sell their products online. They sell via distributers and through emails and phone calls to their main office.
How do I determine PPC ROI for calls, emails and form submissions? They do not want to pay for PPC call tracking, they have one form on the website that send’s email to a sales@ email address and that email address is also posted all over the website as a link along with their phone number.
I can track on the form submissions but will miss ROI on the phone calls and email hyperlinks.
Any suggestions?

Thanks-in-Advance

For the form submissions add a hidden field that contains the campaign info and saves it for conversion counting.

For the generaic emails/calls you can add a "priority code" next to the contact info. Asking customers to mention this priority code when they call in
