# Inventory

Inventory items constitute everything within your enterprise that you buy or sell. An item is interchangeably known as stock, for example in terms such as "Stock Adjustment".

Every item is identified within Accentis Enterprise using a unique, alpha-numeric, user-definable item code. All functions within the system that deal with inventory, such as Sales Orders, Dispatches, Stock Adjustments use item codes.

Items can be classified as stock items or non-stock items. A stock item is an item whose current quantity and value is tracked at all times, whereas a non-stock item is one that can be bought and sold but whose current quantity or value is not tracked (for example, you may want to purchase something called "Stationery" as an office expense without actually stocking it).
