Periodic Inventory vs Perpetual Inventory: What’s the Difference?

An accounting period may consist of weeks, months, quarters, calendar years, or fiscal years. The accounting period is useful in investing because potential shareholders analyze a company’s performance through its financial statements, which are based on a fixed accounting period. Furthermore, certain firms may require management to look around at what’s going on in the company and market.

Without the time period assumption, businesses wouldn’t be able to issue these timely reports. Ultimately, the decision to use periodic inventory depends on sales volume and available resources.
