Has anyone successfully transitioned a long-term client, who is accustomed to hourly billing, to project-based/value-based billing? I have two long-term clients for whom hourly billing has actually been good for a long time, since their projects are often poorly defined. But the nature of my work with them is changing and so how I bill needs to change as well.
What I'm really wondering is how to frame the switch to them. How to get them comfortable with the idea and a slightly different process.
