Asher, 

You are correct. As ona accountant said to me about a similar cost in a
manufacturing setting "they are a variable fixed cost"  . After hearing that
explanation I was glad I was getting ready to change professions.

I looked at it as a fixed cost because I typically  have a pretty good handle
on how many trades per month my system will generate and I can also determine
in advance what my average margin of success needs to be to cover my costs. 

So as a result I consider them as fixed. Regardless, as you pointed out the
real issue is how does that cost impact my system and how do I evaluate that
cost.

Thanks for your input.
