What is inventory?

Definition

Inventory is the goods a business holds to sell, along with the materials it holds to turn into products for sale. It covers finished goods on the shelf, raw materials waiting to be used and work in progress. Inventory is also called stock or trading stock, and its value appears as a current asset on the balance sheet.

Inventory is money in another form. Cash goes out when stock is bought, and it comes back only when the goods are sold and the customer pays. Until then the stock can be damaged, go out of date or stop selling, so a large inventory figure on the balance sheet is not the same as goods that will turn into cash.

What separates inventory from other assets is whether an item is meant for sale, on its own or as part of something the business makes. A café's coffee machine is equipment it keeps and uses, a fixed asset, while the same machine on an appliance shop's shelf is stock.

Accurate inventory records depend on recording every movement of stock: deliveries from suppliers, sales, customer returns, goods sent back to suppliers, and items damaged or thrown out. A stocktake then checks those records against what is physically there.

In Australia

business.gov.au says inventory, also known as trading stock, covers what a business acquires or produces so that it can sell or exchange it. Its glossary gives the two words slightly different meanings: inventory is a list of the goods or materials held for sale, while stock is the goods or materials on hand.

Its inventory management guide suggests listing every item you stock with its name or code, a description, the quantity, supplier details, and its cost and selling price, then grouping items by product type, location or inventory type. It also suggests setting a reorder point for each item, the lowest level you want to hold before ordering more.

Its balance sheet template lists inventory among current assets. Its guidance on improving cash flow ties stock to cash: unsold stock holds money the business could otherwise use. It suggests keeping stock levels from running too high, clearing items that are not selling or are out of date, and considering buying stock only when a customer orders.

Common mistakes

  • Listing tools and equipment the business keeps for its own use as inventory, alongside the goods it sells.
  • Recording sales in the stock records but not customer returns, goods sent back to suppliers or damaged items.
  • Judging the business's position from the inventory figure without checking how much of that stock is slow to sell.
