paid
Stylist Log, which tracks what a hairstylist quoted against what you actually paid.
The definition
What everyone assumes: What you were quoted is what you paid. Corrected to: Quote and payment are separate fields, alongside expected prep and payment method. Stats run on medians, so one unusual appointment can't drag the picture with it.
Where it broke. Those are two different numbers, and the gap between them is the entire reason to keep the log at all.
