+## Stock Location
+
+A stock location represents a physical real-world location where *Stock Items* are stored. Locations are arranged in a cascading manner and each location may contain multiple sub-locations, or stock, or both.
+
+## Stock Item
+
+A *Stock Item* is an actual instance of a [*Part*](/part/part) item. It represents a physical quantity of the *Part* in a specific location.
+
+### Stock Item Details
+
+The *Stock Item* detail view shows information regarding the particular stock item:
+
+**Part** - Which *Part* this stock item is an instance of
+
+**Location** - Where is this stock item located?
+
+**Quantity** - How many items are in stock?
+
+**Supplier** - If this part was purcahsed from a *Supplier*, which *Supplier* did it come from?
+
+**Supplier Part** - Link to the particular *Supplier Part*, if appropriate.
+
+**Last Updated** - Date that the stock quantity was last updated
+
+**Last Stocktake** - Date of most recent stocktake (count) of this item
+
+**Status** - Status of this stock item
+
+### Stock Tracking
+
+Every time a *Stock Item* is adjusted, a *Stock Tracking* entry is automatically created. This ensures a complete history of the *Stock Item* is maintained as long as the item is in the system.
+
+Each stock tracking historical item records the user who performed the action.
