A 'design fee' tactic is suggested every so often in the context of the concern that an end users might shop an integrator's design to others or just waste the time of an integrator to get an extra bid.
An integrator here said:
I was contemplating using the "design fee" tactic. I am new to the game and have already been burned by two companies looking to keep their same integrator honest. Do you feel the fee works for you and also do you think it shy's a lot of people away from even trying to get a bid from you?
So what is your experience with the 'design fee' tactic? How often does it work?
