Amen on the upselling bonus. Make it a commission just as if one of the salespeople had done it. Paid THAT week. And I understand about being able to do better work in less time but still getting the same bonus. In that case it is up to the owner to figure out who is doing the best and most work, and reward them accordingly. When I said to split up the percentage between the installers I didn't neccesarily mean to split it evenly.
