I have been in the residential design build and irrigation business for six years. Recently I have started bidding commercial jobs and winning every bid. I'm not losing money and am doing a descent profit margin on these jobs but somehow feel I'm still leaving money on the table. Different contractors have have given a lot of varying advice on how to bid government and commercial jobs. I'm a bit confused here in Podunk America. Id there some sort of set standard for figuring this? Say a $20,000 residential job would be ??? if it were a commercial job. Thanks for any input.
