Except there is usually handling cost. Time spent researching the requirements for mounting. Screws and hardware that isn't in the estimate that you have to get. Conversations with the provider. On commercial institutional jobs which I am more referring to, we usually end up offloading, storing, moving around.I'd guess he typically just has a standard percentage on markup of items sold. Problem is every job has a different amount of items sold so you can't actually count on any fixed number for your overhead.
But at same time if you are not supplying certain items that does reduce some of your overhead. You don't have to spend the time selecting, ordering, no shipping or handling costs. Hopefully you have already factored installation labor or certain other specialty equipment (maybe a lift) or supplies that might be necessary in whether you are supplying the fixtures or not.
I have a reputation as a pretty good estimator in my region. Some of it is feel though. Kwired is right that the overhead and profit are different for each job. But the bottom line is the bottom line. I have won many jobs where I put profit and overhead to cover owner purchased fixtures. We made money. That is most of what matters. A good estimate is ultimately three things answered yes:
Did you want the job?
Did it make money?
Were you close enough to your competitors that you didn't leave a lot on the table?
