We did a leaf/fall clean up on a 2.5-3 acre property, 4 truck loads of leaves and 1 truck load of brush and debris. I had 5 guys including myself on site for 8 hrs. Looking back through my old estimates and man did I make a big oooops last season!! This years price is more than double of last years price. My thinking is to just bill him because it is what it is on paper and just tell him I made the mistake last year and he should consider himself lucky last year and keep my price what it is. Any thoughts?
