This extension tracks the product stock by its quantity left in the store's inventory. Usually the quantity refers to the number of individually packaged products. The Inventory Planner can not directly track goods that are sold by measurable size. Still, it is possible to use a product unit of measurement as a quantity for the Inventory Planner to be able to track the inventory amount of such products.
For example, a textile is measured in square meters. If the store that sells textiles uses 1 square meter as 1 quantity on the stock, the Inventory Planner module will be able to track the inventory numbers.
