Total inventory value and number of items.
Inventory turnover and days in stock.
Distribution by e.g. category and department.
Use the field selectors to split inventory.
Switch to Inventory and Inventory details to go deeper.
Inventory value is cost-based (valued at the cost price of each stock movement).
