Jessica Spencer this specific situation has not happened to me, and I believe that offering to credit the NOR is important as a hook to get the client to commit to the NOR to begin with. What you should make sure is that always even your most basic amount of work should be higher than what you charge for the NOR, so you can always charge a difference. If you think the job is small and there is a chance that the hired work is equal or lower than what you charged for the NOR then don’t offer to credit it. Now you are in a tough pinch, unfortunately. I am not sure I have any ideas on how to manage this.
