What is a perpetual inventory system?

Perpetual inventory management relies on technology to track inventory with timely data and a high degree of accuracy.

These systems not only streamline inventory control, but also transform warehouse processes into a powerful tool for competitive advantage.

Imagine the impact on your operations if you could all but eliminate stockouts and overstocks. Or reduce carrying costs. Or have reliable visibility at all times. Or deliver exactly what your customers ordered with perfect accuracy.

Perpetual inventory methods offer these benefits and more.

In this article, we will explore the implications, benefits, and implementation of perpetual inventory systems.

Understanding Perpetual Inventory Systems

A perpetual inventory system is a method of inventory management in which transactions are recorded in real time, providing continuous updates to stock levels.

If your operation uses Enterprise Resource Planning (ERP) software, the perpetual inventory system updates the ERP as inventory transactions occur.

To ensure that updates are recorded as they happen, perpetual inventory systems use a combination of software and barcode scanning.

By integrating these technologies with the system of record (e.g. ERP system), every transaction is recorded instantly. Stock levels and order statuses are adjusted automatically. As a result, inventory counts are always up to date.

Technologies Used in Perpetual Inventory Systems

Perpetual inventory needs the right technologies to maintain real-time speed. Essential tools may include:

  • Barcode scanners
  • Tablets or smartphones
  • Radio-frequency identification (RFID) tags
  • Internet of Things (IoT) sensors
  • Point-of-sale (POS) systems
  • Voice picking technology

These physical technology systems are supported by robust inventory management software that integrates with other business systems.

Today’s best inventory management software is built for mobile devices. This way, workers can scan and process inventory wherever they work.

To get perpetual inventory for an ERP, organizations must adopt a high-performance mobile inventory management system.

By integrating some or all of these technologies (including mobile), the business gains a holistic view of inventory levels, sales patterns, and potential issues in real time.

Comparison with Periodic Inventory Systems

In contrast to a perpetual inventory system, a periodic inventory system is a methodology in which updates are made in batches. It’s common for inventory records to be updated at the end of the day or the end of an accounting period.

Naturally, periodic inventory management is sluggish and inefficient. Data is always lagging and visibility is all but absent. Meanwhile, manual processes leave many opportunities for human error.

Needless to say, periodic inventory systems represent the old way of handling stock.

Many warehouses hold on to periodic inventory systems because they are perceived as low cost or just the way they’ve always handled goods. They fail to realize the significant amount of overhead bloat and inefficiency these systems create.

For instance, processing inventory or performing physical counts requires significantly more labor and can lead to discrepancies due to theft, loss, or data entry errors. Unreliable stock records result in wasted time and money, not to mention added stress.

Whereas perpetual inventory provides continuous insights, eliminating the guesswork and inaccuracies associated with manual counts and delayed reporting.

Only with consistently accurate inventory counts can businesses make informed business decisions that positively affect profitability.

Key Advantages of Perpetual Inventory Systems

Companies that implement a perpetual inventory system see many compelling benefits over manual processes. These benefits include:

Real-time Data and Accuracy

The real-time functionality of perpetual systems ensures that inventory records are always current. Compared to paper processes and data entry, the perpetual inventory method leads to drastically fewer errors.

It also eliminates the gap between when work is performed and when it is entered into the system. As a result, overstocking and understocking become far less likely.

With highly accurate inventory data, organizations can bolster operations and maintain customer trust.

Enhanced Warehouse Efficiency

Once inventory movements are updated in real time, managers can pivot quickly. This applies to reordering, sales strategies, allocation of work, and nimbleness to adapt to changing conditions.

Optimally stocked shelves mean picking processes don’t get bottlenecked by stockouts, supplying production and outbound steps with seamless continuity.

Technology plays a large role here. In addition to keeping things moving, solutions like mobile barcoding can also greatly enhance worker productivity and process efficiency by 30% or more.

Cost Management and Reduction

Live, accurate information is essential to reducing overhead and labor costs. Excess inventory can be trimmed. Meanwhile, reliable data helps reduce emergency restocking and expensive last-minute shipping fees. Holding costs such as storage and insurance also go down.

For businesses that handle electronics or perishables, real-time operations lower the risk of obsolescence or spoilage of goods.

Regulatory Compliance and Reporting

Many organizations operate in regulated markets. Regulation means compliance, and compliance hinges on being able to quickly pull the necessary data on demand.

In this way, accurate inventory records facilitate compliance with government and industry regulations while also enabling more precise financial reporting.

During an audit or recall, a perpetual inventory system’s real-time data allows requested information to be easily accessed and verified. This not only speeds up the audit process but positions the company in an agile state of recall readiness.

Improved Customer Satisfaction

At the end of the day, fulfilling customer needs stands above all in terms of importance. Leveraging a mobile inventory solution that enables a perpetual inventory system helps boost customer service.

Some of the ways perpetual inventory systems improve customer service include:

  • Faster order fulfillment
  • Up-to-date stock levels
  • Fewer returns and chargebacks
  • More perfect orders
  • Reduced bottlenecks or delays

Challenges and Considerations

Despite the many benefits of perpetual inventory systems, there are also several challenges and considerations to keep in mind. Addressing these issues will help ensure the system functions effectively and delivers the intended benefits.

Handling Data Inaccuracies

Even the most sophisticated systems can encounter data inaccuracies due to human error, scanning errors, or technical glitches. To mitigate these issues, businesses should implement checks and balances such as routine audits and cross-verifications between the digital and physical inventory.

Training employees on proper scanning techniques and maintaining the hardware in good working condition are also crucial steps.

If adopting an advanced barcode solution like RFgen, the software validates all data against the ERP, preventing invalid inputs from being entered. Human error in regular transactions is very unlikely. Because of this, less effort is required to reconcile inaccurate data.

Periodic Audits and Physical Counts

While perpetual inventory systems significantly reduce the need for frequent physical counts, they do not eliminate the need for periodic audits completely.

These checks are necessary to ensure the accuracy of the system and to identify any discrepancies that might indicate issues like theft, loss, or damage.

Regularly scheduled physical counts can serve as an additional verification layer to reconcile digital records with physical reality.

Alternatively, implementing a system of cycle counts may prove more effective. Automating as much of the cycle counting process as possible with intelligent mobile software is advisable.

Security Concerns

With inventory data being stored and processed digitally, cybersecurity becomes a paramount concern. Therefore, it’s vital to take the necessary steps to protect business data from unauthorized access, data breaches, and other cyber threats.

This involves implementing strong security protocols, regular security audits, and possibly hiring dedicated IT security staff.

A mobile data collection can add an additional layer of security by acting as the hardened exterior barrier shielding your ERP from outside threats.

Implementing a Perpetual Inventory System

When transitioning to a perpetual inventory system, it’s important to be strategic. Walking into such a big change can be disastrous without appropriate planning.

During your preparation, be sure to:

  • Evaluate your current inventory processes

Integrating Perpetual Inventory Systems with Other Business Functions

It’s better to integrate your perpetual inventory technologies with other key business functions than to let it operate in a silo. Connecting disparate systems can significantly enhance operational efficiency and visibility while streamlining data flow across departments.

Some things to consider—

Critical Integration Points

What are your critical integration points? Consider how and where your inventory data can be used.

For instance, integrating a mobile inventory solution with your ERP system can extend the ERP’s capabilities to point-of-work. This equips frontline staff with the ability to transact against the ERP, no matter where they work.

Another integration point may be purchasing and supplier management. Connecting inventory systems with purchasing ensures that procurement decisions are based on current stock levels and forecasted demand, optimizing inventory turnover, and reducing excess items.

Accounting and finance is another area to consider. Integration with financial systems (in addition to the ERP) ensures that inventory transactions are automatically reflected in financial statements, aiding financial analysis and reporting.

If your business uses a sales and customer relationships management (CRM) system, then consider integrating it with your new inventory system. This integration allows sales teams to access up-to-date inventory levels and product information. In doing so, they can better manage customer expectations and upsell or cross-sell based on availability.
