Warehouse Inventory Management Best Practices

From maintaining strong relationships with your supplier to warehouse automation, here are 13 best practices for warehouse inventory management in 2025. 

Manual tasks are often time-consuming and prone to human error. 

Instead of manually counting your inventory, you can utilize automated solutions like warehouse drones, sensors, wearable devices and RFID tags to track and manage your warehouse inventory efficiently. 

Using cycle counting, you can calculate your inventory items in sections, allowing you to evaluate inconsistencies. The cycle length will depend on your inventory’s product group or type and warehouse zone or section. 

For example, higher-valued items should be counted more frequently. 

While there are different ways to perform a cycle count, here’s an example of a cycle counting process using ABC classification: 

• Categorize inventory items: Use the ABC analysis to categorize inventory items into groups based on their value or importance to your business. For example, category A can include high-value items that represent 80% of the inventory value, category B can include moderate-valued items that represent 15% of the inventory value, and category C might include the least-valued items that represent 5% of the inventory value. 
• Determine cycle counting frequency: Determine how frequently you want to cycle count each category of inventory. For example, you can count category A items once a month, while you can count category C items every six months. 
• Conduct cycle counting: Conduct cycle counting activities according to the schedule. Count a small portion of inventory each time and compare the results to your inventory records to identify any discrepancies. 
• Adjust inventory records: Adjust your inventory records based on the results of your cycle counting. Any discrepancies should be investigated and resolved, and inventory records should be updated. 

You can identify your best-selling products by tracking your orders or by performing an ABC analysis. 

After distinguishing which items are most popular — your category A products — move your fast-moving stock closer to the shipping and packing areas in your warehouse for easy access. 

Of course, there’s an even easier, no-fuss way of ensuring your products are easy to reach. 

Modula’s Vertical Lift Modules (VLM) and Horizontal Carousels (HC) are automated solutions that enable:

• Fast access to a large inventory of goods 
• Safe, secure storage 
• Automated delivery with a simple tap on the Copilot interface or a barcode scan 

Make every square foot count by optimizing your warehouse layout. Here’s how: 

Utilize vertical space by: 

• Installing taller storage units 
• Implementing a multi-tier racking system to stack pallets or bins vertically, doubling or even tripling capacity without expanding your footprint 

Improve navigation with: 

• Clear labeling and signage 
• Color-coded signs for aisles and sections to reduce time spent searching for items 

Leverage automation and smart storage by: 

• Using Modula’s VLMs and HCs to take full advantage of the ceiling height and width 

A warehouse manager is responsible for overseeing the day-to-day operations of your warehouse, such as:

• Handling inventory
• Ensuring efficient use of warehouse space
• Managing warehouse employees.

Hire a warehouse manager to ensure that inventory levels in your warehouse meet consumer demand and goods are received and shipped according to schedule.

Demand forecasting is the process of using historical data to predict upcoming demand and ensure your inventory doesn’t run out.It involves analyzing:

• Trends
• Patterns
• Factors that influence consumer demand to make informed predictions.

For example, seasonality can cause SKU velocity (how often each SKU is picked during a specific period) to fluctuate.

So, you can expect an uptick in demand for beach hats in the summer or hotdogs when the 4th of July rolls around the corner.

By monitoring product expiration dates, you can clear out inventory before it expires by lowering prices or offering special deals.

For example, you can run promotions like “Buy One, Get One Free” on these products or set up a clearance section for items nearing their expiration date, offering discounts of 20% to 50% to encourage quick sales.

Conduct regular quality inspections for incoming and outgoing goods to maintain product quality and reduce returns and defects.

For example, implement a standardized checklist your warehouse staff must complete upon the arrival of new shipments.

This checklist should include tasks such as:

• Verifying the number and condition of items 
• Checking for any visible damage 
• Confirming that the goods match the specifications and quantities outlined in the purchase order 

Develop detailed training modules that cover all aspects of inventory management, including the use of inventory management systems (IMS) or enterprise resource planning (ERP) software.

For example, train staff on how to use barcode scanners and RFID technology for accurate inventory tracking, and invite their feedback to continually refine their processes.

A warehouse management system can provide support, monitor your warehouse, and collect real-time data from your automated storage and retrieval systems, regardless of the location.

With Modula’s Warehouse Management System, you can accurately manage and track individual items, from stock levels to product movement and beyond — more on that below!

Effective inventory control begins by understanding your stock levels, inventory performance and replenishment needs. 

To better grasp your inventory, review your products to determine what you have, their value, and how they’re used. Inventory management software can simplify this process. 

Then, maintain accurate records for each item and ensure your system updates with every inventory change. 

Different businesses have different needs, so identify your goals for an inventory management system. 

If reducing storage costs is your priority, consider just-in-time (JIT) or dropshipping methods. If stockouts are frequent, consider maintaining safety stock or switching suppliers. 

Regular communication helps you negotiate better deals and receive early warnings about supply chain delays, allowing you to find alternatives. 

Strengthen relationships with your suppliers by seeking their feedback, collaborating on improvements and consistently paying on time.  

Key Takeaways:

• Automation plays a central role in reducing manual input and errors, enhancing accuracy, and speeding up operations.
• Cycle counting, demand forecasting, and inventory monitoring are essential for maintaining stock levels that match consumer demand.
• Implementing quality control and staff training ensures your warehouse runs smoothly and efficiently.

8 Warehouse Inventory Management Techniques

Managing inventory effectively means using the right techniques for your operation, especially when you’re facing stockouts, overstock, or shifting demand. Here are eight tried-and-true methods to help you take control.

ABC analysis is an inventory management technique that allows you to identify the value of your inventory based on its popularity.

This technique can help you identify fast-moving (popular) items, so you can consistently meet consumer demands.

ABC analysis works by grouping products into A, B and C categories.

• Category A: High-value, fast-moving items that require close monitoring and frequent restocking 
• Category B: Moderate-value items with average movement, managed with balanced attention 
• Category C: Low-value, slow-moving products that require minimal oversight 

Perpetual inventory management is a technique in which you count your inventory as soon as it arrives using radio-frequency identification (RFID) and point-of-sale (POS) systems, to maintain around-the-clock visibility over your inventory levels. 

Economic order quantity (EOQ) is an inventory management technique that allows you to determine the optimal quantity of goods to order so you can meet customer demands and cut inventory costs. 

Inventory costs include: 

• Shortage costs: Costs when your inventory runs out of stock 
• Order costs: Costs when you place an order to restock inventory 
• Holding costs: Costs when you maintain inventory 

This technique works by calculating the costs of holding inventory and the costs of ordering inventory. 

Here is the basic formula for EOQ: EOQ = √((2DS)/H) 

In this formula, 

• D = annual demand for the product (in units) 
• S = cost to place an order (per order) 
• H = cost to hold one unit of inventory for a year (also known as the carrying cost) 
• EOQ = the optimal order quantity (in units) 

By using the EOQ formula, you can find the optimal order quantity that minimizes total inventory costs. 

Safety stock inventory is an inventory management technique that allows you to meet customer demand despite supply chain disruptions and unexpected fluctuations in demand. 

Safety stock is additional goods that you store in your warehouse in case supply shortages or transportation delays occur. Think of it as your cushion to prevent an out-of-stock situation. 

You can utilize this technique when your supplier can’t deliver more of your inventory or when there’s a shift in customer demand. 

To implement the safety stock inventory technique: 

• Determine the level of safety stock you need — typically about 50% more of your average inventory quantity 
• Monitor inventory levels using a warehouse management system 
• Reorder goods when your inventory levels fall below the safety stock level 

Batch tracking is an inventory management technique that allows you to monitor inventory expiration dates or track defective items back to their original batch to help you ensure quality control and seamless product recalls.

This is particularly important in industries such as

• Food and beverage 
• Pharmaceuticals 
• Cosmetics 

This technique works by assigning a unique batch or lot number to a specific inventory group, to track production and expiration dates, along with storage and handling conditions.

Dropshipping is an inventory management technique that allows you to ship products directly from your third-party supplier or manufacturer, rather than storing inventory in your own facility.

To implement dropshipping, you purchase items from a third-party supplier, who then ships them directly to your customers.

The biggest benefit of this model is that you don’t need to store inventory, avoiding storage costs. This makes it popular among online businesses, allowing them to offer a wide variety of products without major overhead costs.

FIFO, or first in, first out, is an inventory management technique in which you sell your older inventory first, making way for newer items to keep your inventory fresh. 

On the other hand, LIFO or last in, first out, is a technique in which you sell your latest inventory first, allowing you to save on taxes by increasing the cost of goods sold (COGS). 

Just-in-time (JIT) inventory management is a technique that allows you to prevent dead stock, or unsold inventory, by only ordering and receiving items when needed. 

Ultimately, your supplier only delivers inventory to your warehouse once a customer places their order. As a result, you don’t have to store inventory that might end up as dead stock. 

3 Key Principles for Inventory Management

Strong inventory management practices rely on more than just process—they need the right principles and tools behind them. Here are three key areas that support efficiency and long-term success.

Lean principles help eliminate waste and improve daily operations. The 5S methodology is a practical starting point:

• Sort (Seiri): Eliminate unnecessary items from the workspace to reduce clutter and improve organization.
• Set in Order (Seiton): Arrange necessary items systematically for easy access and efficient workflow.
• Shine (Seiso): Maintain cleanliness to identify and address issues promptly.
• Standardize (Seiketsu): Establish standardized procedures to maintain consistency and quality.
• Sustain (Shitsuke): Cultivate discipline to adhere to established processes and continuously seek improvement.

These practices create a more efficient and organized warehouse for better inventory control.

Implementing a Warehouse Management System (WMS) is essential for modern warehouse operations. A WMS offers comprehensive tools to manage inventory, optimize storage allocation, and ensure timely order fulfillment. Key benefits of a WMS include: 

• Improved Inventory Accuracy: Real-time tracking of stock levels reduces discrepancies and enhances inventory control. 
• Optimized Storage Utilization: Efficient space management leads to better organization and increased storage capacity. 
• Enhanced Order Processing: Streamlined workflows result in faster and more accurate order fulfillment. 

By leveraging a WMS, warehouses can significantly boost productivity and maintain a competitive edge in the industry.  

Technologies like AS/RS, AMRs, and barcode systems help automate and optimize daily warehouse operations.

• Automated storage and retrieval systems (AS/RS): speed up picking and minimize errors  
• Autonomous mobile robots (AMRs): move goods within the facility, reducing manual labor  
• Barcode scanners and tracking tools improve data accuracy and reduce cycle time

By adopting these technologies, warehouses can improve productivity and maintain a competitive advantage in the market.

7 Warehouse Inventory Management Processes

Warehouse inventory management involves six core processes, including: 

• Receiving: First, inventory is checked in and logged to ensure items are in good condition and in the correct quantity. 
• Put-away and storage: In this step, the inventory is put away and properly stored in its designated warehouse location. For example, fast-moving items are stored near the shipping area for easier access. 
• Order processing: Next, the customer places an order, which can be verified in person, via email, telephone, or online.
• Picking: Then, the correct product and quantity are picked. Picking aids, such as voice picking technology, put-to-light systems or laser pointers, are utilized to ensure accurate picks. 
• Packing: In the packing step, the picked items are prepared for shipment. Orders are safely packed in bubble wrap or other protective material to reduce the risk of damage. Then, the package is sealed and marked with a shipping label that displays key information, such as the tracking code and the customer’s name and address. 
• Shipping: Finally, orders are documented and shipped out to the right customer at the right time. 
• Returns: Returned items are inspected for damage and resellability. If resellable, the item is added back to inventory and a refund or exchange is issued to the customer.
