# Inventory variants

A **variant** is a specific combination of parameter values within an inventory type.

For example, a work-boot type can use **Shoe size** and **Toe cap**. Each permitted combination becomes a distinct variant whose quantity is tracked separately.

Inventory+ uses the type's configured parameters and allowed values to keep nomenclature consistent and prevent arbitrary duplicate variants. Quantities, transfers and write-offs always refer to a specific variant.
