Commissions: hourly rate or one flat price?
Some artists swear by hourly — it protects you from scope creep and rewards every minute spent. Others refuse to quote anything but a flat fee — clients get certainty, you get rewarded for speed, and nobody's watching the clock. I go back and forth on this myself; both camps have a point, and both have gotten burned the other way.

A flat fee makes the most sense to me: I don’t think it is fair to be punished for either taking your time or being super efficient with your time. That calculation should be done on the artists side only. The actual hours of work do not show the full process and the experience that built up the skill used in those hours.
