Any business with more than one storage location - a shop floor and a back warehouse, say - can track stock separately per location while still seeing the combined picture.
From the sidebar, go to Inventory to see your Total Stock Value, Unique Products count, Inventory Turnover, and any Stock Alerts (low or out-of-stock items) at a glance.
This breaks down stock value and item counts per warehouse, so you can see which location is overstocked or running low.
Open a warehouse to see its individual stock levels and locations (aisles, shelves, etc.) within it.
If a physical count doesn't match the system (damage, loss, a manual count), use the stock adjustment option on a product to correct it - every adjustment is logged.
