The light bills are always paid from your net revenue and not your gross..... Net profits always vary from person to person and are contingent upon a variety of different things including how the company was setup, type of expenses, etc. When considering any opportunity, always do your own math as even at the same gross number, two businesses can have two VERY different net numbers. (This is why you avoid the “how profitable is lane “x” “ because it isn’t the lane that determines the profit, it is how you run YOUR business! The lane can only render you a gross number...)
