Learn procure-to-pay the way language apps teach languages: one small stop at a time. Each stop is a three-minute idea and one question. Get it right, the next stop unlocks. Four units take you from "someone needs boxes" to reading the cost engine like a senior. Your progress saves in this browser, leave and come back anytime.
Stops unlock in order. The star stops are checkpoints: a few questions on everything before them. Wrong answers cost nothing, you just try again. By stop 20 you will know the accounting story behind every purchase, which is the skill that separates seniors.
