I think you both make good points. I'm more in agreement with you than the author, but I voted up the article for this line which is a gem: > Any client will have grand dreams of his product. He will constantly ask for new things, and think those were naturally implied from his vague sketches. If you have quoted a fixed price, and you were smart enough to have a detailed contract, you will need to fight him on every step, saying "we didn't spec that". Whereas, with an hourly rate, you can say "sure, let me estimate how much will this be". The client can then decide if it's worth the money. Perhaps his method is better for projects with unclear scopes or first time buyers, and yours for clear scopes and veteran buyers? I see merit and potential uses for doing it either way, depending on the circumstances.
