I was on a comission plan before I went out on my own. It was 1% of my gross income from jobs I did that month......some jobs I sold myself but most were already setup quoted price.

The commision was in addition to my regular check also.

In my case the commision was based more on production than on what I sold. It gave employees the extra incentive to get the job done as quickly as possible, there was also clauses that made sure the job passed all inspections and was actually profitable.

For us it worked out, I averaged $40,000/month in jobs and I got an extra $400/month average, I made sure my helper was taken care of also... lunch bought for him everyday etc. as they say "everything rolls down hill" that applies to good and bad

Now to what you guys are saying, I agree, I don't think this should apply to people actually selling the job, I mean that would make us like a car salesman selling the undercoating
