Quite honestly I don't want to charge different prices and have to keep track of what task I'm working on. I try to figure three different things: material cost, laser time, labor time. My "hourly wage" and overhead remains the same and I generally don't break it out as far as if I'm running the laser or the computer.

The pricing module I am testing determines a flat minimum rate I should charge for any billable time no matter what I'm doing. So, let's say the module gives me $50/hr as my minimum. That will cover my hourly wage and overhead. According to many people on the forum running a laser $50/hr is quite cheap so I would figure production time at $50/hr and add the laser time at $x/hr and marked up material costs. That should cover all my bases.

I'm still new and learning with each job. We'll never all agree on one perfect pricing strategy. As long as my customers are happy and I make a decent living doing what I love, I'll be happy.
