Perpetual vs. Periodic Inventory
Perpetual Inventory System
- Record the quantity and cost of each item when they are bought, kept in inventory and sold.
- Provide detail information so that merchandise availability can be known.
- Record increase and decrease of merchandise to “Inventory account”.
Periodic Inventory System
- Use temporary account to add the increase and decrease in merchandise, usually called “Purchase account”.
