I'll try to make the time to write up something. It's really a matter of explaining to them why our way of working ends up being faster and less expensive than the flat fee way. With our way of working, there's an assumption of trust, and we keep that trust through visibility of our progress. That way we share risk, and if we can share risk with the client, we can charge less, because we don't have to build in such a big margin in the price to cover our risks.
