What Is the Difference Between Periodic and Perpetual Inventory?

Inventory management is a critical part of any business that deals with physical goods. Whether you’re running a retail store, an e-commerce business, or a manufacturing unit, how you track your stock can significantly impact efficiency, profitability, and customer satisfaction. That’s where the debate between perpetual vs periodic inventory comes in.

Understanding the difference between periodic and perpetual inventory system helps businesses determine the most effective method for tracking their stock. Some businesses require real-time stock updates to ensure smooth operations, while others operate just fine with scheduled stock counts at the end of an accounting period.

At Infizo Stock, we empower businesses with advanced inventory tracking solutions tailored to their operational needs. Whether you need barcode/RFID-enabled perpetual tracking or a structured periodic inventory management system, our software ensures accuracy, efficiency, and seamless stock control.

In this blog, we will explore the periodic vs perpetual inventory system, their advantages, and which approach best suits different business models.

What Is Periodic Inventory?

A periodic inventory system is one of the oldest methods used for stock tracking. Businesses update their stock records at scheduled intervals, typically weekly, monthly, quarterly, or annually. Instead of tracking inventory in real-time, businesses conduct physical stock counts to determine stock levels and the cost of goods sold (COGS).

How Periodic Inventory Works

1. Physical Count-Based Tracking
   • Businesses rely on scheduled manual stock counts to determine inventory levels.
   • The frequency of counts depends on the industry, business size, and available resources.
2. Retrospective COGS Calculation
   • Since inventory is not tracked in real-time, COGS is calculated retrospectively at the end of the period.
   • Formula: Beginning Inventory + Purchases - Ending Inventory= COGS
3. Less Dependence on Technology
   • Unlike perpetual inventory, periodic inventory does not require advanced tracking systems.
   • Ideal for businesses with a simple inventory structure and budget constraints.

How Infizo Stock Supports Periodic Inventory

1. Scheduled Physical Stock Audits
   • Infizo Stock automates reminders for periodic stock checks.
   • Businesses can configure custom stock verification schedules.
2. Accurate Inventory Reports

   • Provides data-driven insights for improving replenishment cycles.
3. Ideal for Cost-Conscious Businesses
   • Small businesses, wholesalers, and companies with slow-moving inventory can manage stock effectively without investing in complex tracking technologies.

Although periodic and perpetual inventory systems both track stock, periodic inventory is better suited for businesses that do not require continuous stock tracking.

What Is Perpetual Inventory?

‍Unlike periodic inventory, a perpetual inventory system accounting continuously tracks stock in real-time. Every sale, purchase, or movement is recorded automatically, ensuring instant updates on stock levels.

‍How Perpetual Inventory Works

1. Continuous Tracking
   • Inventory records are updated instantly after every transaction.
   • Eliminates the need for manual inventory counts.
2. Technology Integration
   • Uses barcode scanning, RFID tracking, and cloud-based inventory software.
   • Ensures accurate and automated stock control.
3. Instant COGS Calculation
   • Unlike periodic inventory, COGS is updated automatically in real-time.
   • This helps businesses monitor financial data more accurately.
