Menu engineering
“Which service really earns me the most?”
Each dot is a service. The further right, the more you sell it; the higher up, the more it earns for every hour you spend on it. Top right are the ones to push, bottom left the ones to think about. The size of the dot says how many times you do it.
Why you can trust this number
The sum is on what an hour of your time earns, not on the price of the service. It looks like a subtlety and it's the most useful reversal there is: a €25 blow-dry in twenty minutes earns you more than a €70 colour that takes two hours. A price list read by price would tell you exactly the opposite, and that's why so many salons push the wrong thing.
