What ATUM does
Inventory management with purchase orders, suppliers and stock forecasting for WooCommerce.
It sits in the inventory part of a WordPress stack and is sold by Stock Management Labs on a freemium basis. We recommend it in our inventory guides because it does that one job well without asking you to rebuild the rest of the site around it.
Every plugin adds work to a page request, so treat this as a decision with a cost. Record a speed test before you install it and run the same test afterwards, on the same page, so you know exactly what it charged you.

Where ATUM ranks elsewhere
ATUM does not appear in the published "best of" lists we track from WPBeginner, TechRadar, Kinsta, Themeisle and similar sites. That is not a mark against it - those roundups are short and skew towards the biggest names.
What changed in the latest version
ATUM does not publish a changelog we can read automatically, so check the vendor's own release notes before you update a live site.
