In Accentis Enterprise, every inventory item that is designated as a stock item can have a quantity in stock and a total value in stock. When any transaction occurs that affects the quantity in stock, it will also affect the total value of that stock. For example, when you buy more stock and receive it into inventory through a goods Receive transaction, both the quantity and total value of that item will generally increase. When you deliver stock to a customer and remove it from inventory, both the quantity and total value of the stock will generally decrease.
At any point in time and for stock items only, the total value of stock divided by its total quantity in stock is referred to as the item’s Average Cost. If there is no quantity in stock of an item, its average cost is always zero. These calculations are on a per-warehouse basis; the average cost of an item code in one warehouse may not be the same as the average cost of the same item code in a different warehouse.
