Inventory. Stocks of goods held by the firm over a period of time.

In the I-O accounts, inventory includes:

  • products purchased for resale, generally held by wholesalers and retailers
  • materials and supplies for use in the production of goods for sale or in the provision of a service
  • products that are partly processed and that require further processing prior to sale (work in process), and
  • finished goods held for sale.[1]
