+1What the file tells you
A price rise is a bet on how many customers stay. This sheet makes the bet honest: for every price you are considering it shows profit after the customers you expect to lose, and the one number that settles the argument — how many you could lose before you are worse off than today.
Freelancers, makers and small businesses who have not raised prices in two years and are afraid to.
