They are now nitpicking at a minimum of one hour billed for one-off projects For no other reason that this, I would drop them. I do not like having to justify my time after the fact. They hired me because I am the expert, as such if it takes 5 hours to complete, they should have an issue with that up front not after the work has been preformed. If a client tries to negotiate hours after they have been performed, it is the last time I work for that client. The issue is, what if they have a huge emergency that required a good portion of hours, if they nit pick over a few, there is a good possibility in this situation, they will have buyers remorse after the crisis is over, potential stiffing you with a lot of hours, worse yet a lot of hours at a sub par bill rate. There is a high potential for you to get stuck holding the bag with a client like this.
