Ruel, you can't/ won't want to climb forever. Developing your own client base and building your biz, including establishing biz credit for buying equipment, while collecting a check from someone else seems to be many people's recipe for success.
Anyone who wants to show profits/ give percentages, should also show a log of hours off the jobsite for billing, bidding, repairs, licensing, etc, etc. Show the cost of worker's comp, costs for repairing equipment, GL insurance.
If the boss is clearing 20K profit, and has 20K invested its one thing. If they're cleaning 20K a month, and have to manage 10 employees, and have $3M invested, its different worlds.
I was wondering recently, what people's Gross Revenue: Net Income ratios are like.
I kept over half my revenue. I imagine larger corps don't, in part because I am not accounting for all the hours I spend working. Actually, i have no idea how many hours I work in a year.
