What Is Lot Tracking in Warehousing? (August 2026)

Faith Artieda • August 10, 2026

Lot tracking in warehousing is the process of assigning and monitoring a unique lot or batch number for groups of products throughout the supply chain. It helps businesses maintain inventory accuracy, improve product traceability, manage expiration dates, and quickly identify affected inventory if a recall occurs.

Key Takeaways

Lot tracking allows businesses to trace products from receipt through fulfillment using unique batch or lot numbers.
It improves inventory accuracy, supports product recalls, and helps businesses manage expiration dates and regulatory requirements.
An experienced 3PL with advanced warehouse technology can simplify lot-controlled inventory management while improving visibility across the supply chain.

Why Is Lot Tracking Important in Warehousing?

For many industries, knowing exactly where inventory came from and where it was shipped isn't just a best practice—it's a business requirement.

Lot tracking gives businesses complete visibility into specific groups of products as they move through the warehouse. Instead of treating inventory as identical units, products are tracked by their assigned lot or batch number, making it easier to identify when they were received, where they're stored, and which customers received them.

This level of traceability is especially valuable for companies that manage products with expiration dates, shelf-life requirements, or strict quality standards.

How Does Lot Tracking Work?

When inventory arrives at a warehouse, each lot is recorded with its unique identification number. Depending on the product, additional information—such as manufacturing dates, expiration dates, or supplier details—may also be captured.

As inventory moves through receiving, storage, picking, and shipping, the warehouse management system maintains the connection between each product and its assigned lot number. This creates a complete record of inventory movement throughout the fulfillment process.

If a quality issue or product recall occurs, businesses can quickly identify which inventory is affected rather than placing every unit on hold.

Which Industries Benefit Most from Lot Tracking?

Lot tracking is particularly important for businesses that distribute regulated or date-sensitive products.

Industries that commonly rely on lot-controlled inventory include:

Food and beverage
Consumer packaged goods (CPG)
Health and beauty
Nutritional supplements
Medical devices
Pharmaceuticals
Pet food

For these businesses, lot tracking supports inventory accuracy while helping ensure products are shipped according to customer and regulatory requirements.

How Does Lot Tracking Improve Inventory Management?

Lot tracking provides greater control over inventory by giving warehouse teams detailed visibility into product movement and availability.

For products with expiration dates, warehouses can follow inventory rotation methods such as First Expired, First Out (FEFO), helping ensure older inventory ships before newer inventory when appropriate. This reduces spoilage, minimizes waste, and improves inventory utilization.

Businesses also gain more accurate inventory records, making forecasting, replenishment, and quality management easier.

How Does Warehouse Technology Support Lot Tracking?

Managing lot-controlled inventory manually can quickly become complex, especially as product volumes increase.

Modern Warehouse Management Systems (WMS) automate much of the lot tracking process by recording lot numbers during receiving, maintaining traceability throughout storage and fulfillment, and providing real-time inventory visibility.

Barrett Distribution utilizes a Tier 1 Warehouse Management System that supports advanced inventory management and real-time visibility across warehouse operations. The company's technology platform, customer dashboards, and reporting tools help customers monitor inventory and fulfillment performance with greater accuracy.

This technology helps businesses manage lot-controlled inventory more efficiently while reducing the risk of manual errors.

Can a 3PL Help Manage Lot-Controlled Inventory?

Yes. An experienced third-party logistics (3PL) provider can simplify the complexities of lot tracking by combining technology with standardized warehouse processes.

Barrett Distribution supports customers with sophisticated inventory control capabilities, including lot and expiration date management for products that require enhanced traceability. These capabilities are particularly important for industries such as food and beverage, where inventory accuracy and product quality are critical.

By partnering with a 3PL that has experience managing lot-controlled inventory, businesses can improve operational efficiency while maintaining confidence in their inventory data.

Is Lot Tracking Right for Your Business?

If your products have expiration dates, are subject to regulatory requirements, or require detailed traceability, lot tracking should be an essential part of your warehouse strategy.

Even businesses outside highly regulated industries can benefit from improved inventory visibility and stronger quality control. As supply chains become more complex, having the ability to quickly trace products throughout the fulfillment process helps reduce risk, improve customer service, and support long-term operational success.

Whether you're shipping food products, cosmetics, consumer packaged goods, or other lot-controlled inventory, working with an experienced logistics partner can help ensure your warehouse processes are built for accuracy and scalability.

What Can You Learn About a 3PL by Walking Through the Warehouse?

By Faith Artieda • September 24, 2026

Every 3PL can build an impressive presentation. You can review technology, locations, capabilities, services, and carefully selected photographs of the operation, all without ever stepping inside the building. Those details matter, of course, but they only tell part of the story. What happens when you leave the presentation behind and actually walk through the warehouse? Almost immediately, fulfillment becomes more tangible. Instead of hearing how an operation works, you can watch it unfold around you. Inventory is being received, orders are moving through the building, teams are communicating, and the people who could eventually be responsible for your products are doing the work right in front of you. For a prospective customer, that experience can reveal far more than another slide ever could. That philosophy is one of the reasons Barrett Distribution Centers hosts open houses. Mary Glenn, Director of Business Development at Barrett, recently reflected on Barrett's Memphis open house and explained that the intention was never to bring prospective customers into a building just to deliver another sales presentation. “This wasn’t going to be a sales pitch. This wasn’t going to be, you know, come and get PowerPointed to death.”

How Can Apparel Brands Manage Seasonal Inventory? (2026)

By Faith Artieda • September 24, 2026

Apparel brands can manage seasonal inventory by combining accurate inventory visibility, demand planning, flexible warehouse operations, and omnichannel fulfillment. The goal is to have the right products available when demand increases without creating unnecessary inventory challenges after the season ends. A 3PL can help apparel brands prepare for seasonal fluctuations by providing warehouse infrastructure, technology, labor planning, and fulfillment processes that can adapt as order volumes change. Key Takeaways Seasonal demand can create major changes in apparel order volume and inventory requirements. Inventory visibility helps brands understand what products are available across the fulfillment operation. Flexible warehouse and labor planning can help operations respond to changing demand. Omnichannel fulfillment is important when seasonal inventory must serve both ecommerce and retail customers. Why Is Seasonal Inventory Challenging for Apparel Brands? Apparel demand can change significantly based on the season, holidays, promotions, and new product introductions. These fluctuations can affect how much inventory enters the warehouse, how much storage is required, and how quickly orders need to move through fulfillment. Barrett identifies retail seasonality, promotions, product introductions, and demand volatility among the challenges involved in omnichannel and retail fulfillment. How Does Inventory Visibility Help With Seasonal Demand? Brands need a clear understanding of what inventory is available as seasonal demand changes. Warehouse technology and reporting can provide visibility into inventory, inbound orders, outbound orders, and operational performance. This information can help brands and their logistics partners make better decisions as inventory moves through the season. Barrett provides customers with secure web-based access to inventory, item master information, inbound and outbound orders, reporting, and operational dashboards. How Can a 3PL Prepare for Seasonal Order Spikes? Seasonal fulfillment requires more than additional warehouse space. Operations may also need to adjust labor and workflows as order volumes change. Barrett's analytics capabilities include labor planning and productivity measurement, while its Barrett PLUS labor management solution incorporates data from warehouse systems and other operational sources. Planning around expected demand can help the warehouse prepare resources before seasonal volume arrives. How Does Omnichannel Fulfillment Help Manage Seasonal Inventory? Seasonal apparel inventory may need to serve several channels at once. An ecommerce promotion can increase DTC orders while the same brand is also fulfilling wholesale and retail demand. Each channel may require different fulfillment processes even when inventory is managed within the same broader operation. Barrett supports B2B and B2C omnichannel fulfillment for consumer, distributor, and retail customers, allowing different order types to be supported within its fulfillment operations. Why Are Flexible Warehouse Processes Important? Seasonal demand rarely looks exactly the same throughout the year. Apparel brands need fulfillment operations capable of adapting to changing order profiles, promotions, and retail requirements. Barrett's WMS capabilities include customer-specific processing and real-time tasking, while its continuous-improvement approach emphasizes documented processes, training, and operational optimization. These capabilities can support a more flexible approach as fulfillment requirements change. What Should Apparel Brands Look for in a Seasonal Fulfillment 3PL? Look for a 3PL that can support more than peak-season shipping. The provider should have strong inventory management, technology, labor planning, B2B and DTC fulfillment, retail compliance, and reporting capabilities. Apparel experience is also important because seasonal inventory often intersects with retail promotions, product launches, value-added services, and customer-specific requirements. Barrett identifies Apparel & Footwear as a core vertical and combines omnichannel fulfillment with warehousing, value-added services, transportation management, and retail compliance. Frequently Asked Questions What is seasonal inventory in apparel? Seasonal inventory is merchandise whose demand is closely connected to a particular season, holiday, promotion, or selling period. How can a 3PL help with seasonal demand? A 3PL can provide warehouse capacity, fulfillment processes, labor planning, inventory visibility, technology, and transportation capabilities to support changing order volumes. Can seasonal inventory support both retail and ecommerce orders? Yes. An omnichannel fulfillment operation can support both B2B and DTC orders, although each channel may require different fulfillment processes. Does Barrett support seasonal apparel fulfillment? Barrett serves the Apparel & Footwear vertical and its omnichannel experience includes managing challenges such as demand volatility, retail seasonality, promotions, and product introductions.

What Should Your First 30 Days With a New 3PL Look Like?

By Faith Artieda • September 23, 2026

The contract is signed. Your inventory is moving. Systems are being connected. After months of comparing providers and talking through every detail, your new 3PL relationship is finally becoming real. The first 30 days should not be about handing over the keys and hoping everything works. They should be about turning everything discussed during the sales process into something your customers can actually rely on. Scott Wilkins , Vice President of Customer Solutions at Barrett Distribution Centers, has described implementation as an important moment in establishing that relationship. “The implementation itself really sets the stage for that relationship. The more information that you have up front, the better off that relationship is going to get off on the right foot.” So, what should those first few weeks actually look like? Week One: Get Everyone on the Same Page The beginning should involve a lot of communication. Your 3PL needs to understand more than how many orders you ship. This is the time to confirm inventory details, sales channels, packaging requirements, retailer expectations, technology needs, transportation requirements, upcoming promotions, and the small details that make your business different. You should also know the people involved. Who is your main contact? Who is responsible for operations? Who handles systems questions? Who gets involved when something unexpected happens? Scott describes the work behind building a customer solution as a team effort, saying, “It takes a small army to develop and submit a potential proposal.” That collaboration becomes even more important once the proposal turns into a real operation. Weeks Two and Three: Turn the Plan Into an Operation This is where a lot of the behind the scenes work happens.
