I have planned a revenue of 600k this year. As Brooke suggests in the Entrepreneur Bookkeeping, I have deducted my profit first, taxes and marketing costs, to see how much I have left for expenses. Now, the thing is that if I don’t make that revenue (which would be a little more than double last year’s revenue) I don’t have that money to spend. If I don’t spend that money, I won’t make that revenue. What do you recommend, how should I look at this?
