Do you know of any good resources for getting started with value billing, especially for web design/development? We mainly build websites for small/medium sized businesses, and I anticipate needing to do a lot of education/selling on a possibly unfamiliar pricing system. I'm aware of this book aimed at consultants: http://www.amazon.com/Value-Based-Fees-Ultimate-Consultant-Pfeiffer/dp/0470275847 http://www.amazon.com/Value-Based-Fees-Ultimate-Consultant-P... but I'm not sure how well that will apply to my situation.
