My company is getting bigger now and I am getting into commercial mowing. I have been doing residential for years this is easy bidding. It is always by the cut no problem now I am bidding small apartment and they want a contract pricing. Our lawn care season is April-Oct 7 months this is how I doing it hours to cut the grass x my hourly rate (per machine) x 31 weeks than divide by 7 and thats there monthly bill and than add in all the extra's fert mulch if they want it and divide that by 7 and than add that to the total monthly bill. Does that make sense? LOL how are you guys doing it?
