I handed in an estimate for a very bureaucratic client. I had never worked with them before.
Client: Everything looks fine and we would like to work with you – under one condition. Could you please remove the line about the corrections?
Me: The two corrections per (predefined) project-stage?
Client: Yes, we don’t feel comfortable with limiting the amount of corrections.
Me: No problem, this will not be a fixed estimate then. I’ll change it to the hourly rate and keep you informed of my time spent on the project.
Client: No, we don’t like that. As a professional you should know exactly how many hours you will be working on this.
Me: So, fixed time, with unlimited corrections that could take an unknown amount of time.
