perpetual inventory system

Dictionary of Accounting Terms for: perpetual inventory system
perpetual inventory system

one keeping continual track of additions or deletions in materials, work-in-process, and cost of goods sold on a day-to-day basis. Physical inventory counts are usually taken at least once a year in order to check on the validity of the book records. Cost of goods sold therefore is kept on a day-to-day basis rather than being determined periodically.
