I ran and owned part of a construction materials business in a small market and had 3 other competitors - one and a half too many for the size of the market. When the dust settled every year, we had a Net profit of 2%. This was after all expenses, overhead, payroll, benefits, etc. were paid out, hence Net. The 2% was equal to the cash discounts we made damn sure we took when we paid our bills ON TIME. We operated anywhere from a 5% to 15% gross margin and were considered to be the leading business of our type in the area.
So.....wtf does this have to do with anything?
Can you say VOLUME? Don't fall into the trap of equating points of gross margin with numbers of dollars. 1% of $1B = $10M and that ain't hay.
Only dumbasses fall for that logic.
