# Tags Add custom 'Tags' in the 'Tags' section when adding or editing an inventory item to distinguish differences between different inventory items that are the same ingredient. (i.e date purchased, batch code, date packaged or manufactured, etc.) When selecting ingredients in the 'Recipe Builder', the tags are visible for inventory items, allowing you, for example, to select to use the older item that is tagged accordingly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
