Step 1 of 5

What this does

Your register already wrote down every sale you made. We read ninety days of it, set it beside how many people were in the room at the time, and tell you the headcount your bar makes the most money at. There is nothing to install and nothing to change about how you work — you send us two files your till and your door counter already produce.

dR/dN is math shorthand for: what's one more customer worth?
