Profit first

Author Name: Mike Michalowicz

The author of the classic book, The Pumpkin Strategy, offers a simple and exceptional cash management solution that helps small businesses break out of the doomsday spiral and achieve immediate profitability.
Traditional accounting uses the logical (albeit flawed) formula: Sales – Expenses = Profit. The problem is that businesses are run by people, And humans
They don't always make sense. Successful entrepreneur Mike Michalovich has developed a behavioral approach to accounting to flip the formula: Sales - Profits = Expenses. Just as the most effective weight-loss strategy is to reduce portions by using smaller plates, Michalovich explains that by generating profits first and allocating only the remainder to expenses, entrepreneurs will transform their companies from money-guzzling monsters into cash-generating cash cows.
“Finance is the biggest headache for entrepreneurs. It's essential to read Profit First to avoid bankrupting great business ideas. Smart, easy to apply, and totally effective (plus, you'll enjoy reading it).” – Sofia Macias, author of The Little Piggy Capitalist
