Once a Product has been added to Silo, various attributes of that product are tracked and kept up to date. For example, Silo keeps track of the latest price of the product (where possible), and Silo tracks when your team 'consumes' boxes of the product. When attributes change (such as an item running low on stock) you may get alerts and warnings.
A product 'Tracked' like this appears in your main Inventory list. If you stop using a product, or want to stop receiving updates about it, you can Untrack it.
To Untrack a product, select it in the Inventory list and click the Untrack icon.
To see all Untracked items, select 'Show Untracked Products' in the Filter dropdown.
