Available-to-Promise (ATP)
The uncommitted inventory a business can promise to new orders right now.
Also known as: ATP
What is Available-to-Promise (ATP)?
Available-to-Promise (ATP) is the quantity of inventory that is genuinely available to commit to new orders — on-hand stock minus what is already allocated, plus expected inbound within the horizon. It is the number that should drive what you can sell, but many brands quote from raw on-hand and oversell. Accurate ATP across every channel is the foundation of not promising stock you don’t have.
How Endless handles it
Endless computes ATP in real time across channels from one inventory truth, so a unit promised on Amazon can’t also be promised to a wholesale PO.
