It's vague, because it's a high level idea. I want to earn more than I can by time, therefore I have to get clients to start thinking about how much value they are getting and paying for that. Practically I've had success recently by charging weekly. I keep this rate deliberately lower (about half my old full time consulting rate). Then I send them a weekly report along with the invoice every week. They get to see exactly what they got for the money. It usually takes me 15-20 hours to deliver enough value for the weekly rate. So there are lots of things to try. Small changes in billing can have a large impact on your relationship with your client.
