Systemized logistics and warehouse management have increasingly become the backbone of global commerce in a world dominated by just-in-time supply and demand scenarios. Warehouse operations have grown far beyond simple storage or transportation and now require real-time data, interconnected systems, and, most importantly, operational efficiency. 

As enterprises strive to cope with these intricacies, the need for robust Warehouse Management Systems (WMS) has never been more compelling - and critical. These systems offer a multi-faceted approach to managing various tasks, from inventory management to interfacing with enterprise resource planning (ERP). A digital WMS has become the distinguishing gateway to unparalleled competitive advantages for the modern digitalized warehouse.

What is a Warehouse Management System (WMS)?

A Warehouse Management System (WMS) is a software platform that constructs and deploys policies and processes that organize the work conducted in a warehouse. The goal is to ensure that the warehouse or distribution center can meet its objectives while operating as efficiently as possible. 

Today’s warehouse operations necessarily extend beyond software that merely keeps tabs on inventory. Now, warehouse ops require more holistic approaches to managing all its activities. Everything related to warehouse operations management has the potential to be optimized, including inventory amounts, inventory location, order fulfillment, shipping logistics, personnel workflow, and much more. 

Often, multiple systems must exchange information to handle more complex scenarios. Therefore, a WMS often dovetails with enterprise resource planning (ERP) solutions, creating a seamless operational backbone that keeps businesses running smoothly.

Inventory Management

At the heart (and start) of the WMS lies the activity of inventory management - a feature that helps organizations keep track of goods across one or multiple warehouses. Automation and real-time data tracking minimize manual errors and ensure the inventory is always up-to-date. 

Inventory management in a WMS forms the cornerstone for connecting warehousing operations to broader supply chain activities. From this beginning, the WMS has emerged with countless features offering a massive portfolio of benefits to operations teams looking to stay aligned with modern commerce and its consumer expectations. 

WMS and ERP: Strategy and Integration

Beyond the WMS’ feature-rich platform, many other systems still require attention within a supply chain. While a WMS can often perform as a stand-alone tech solution optimizing its target domain, it typically isn’t deployed in a silo. This means other systems must communicate with it, requiring integration functionality to optimize communications and data sharing between platforms.  

Thus, the WMS often works with various technologies in a complementary relationship to deliver comprehensive oversight and granular control to the supply chain.

The rest of this article will focus exclusively on the functionality, benefits, and structure of Warehouse Management Systems. In conclusion, we’ll let you know how to learn more if it’s time to initiate your first WMS or integrate and bring your systems up-to-date.

What Does a Warehouse Management System (WMS) Do?

A WMS plays multiple roles in the warehouse, from operational to strategic. From a functional standpoint, it serves as the linchpin for an array of tasks - from when goods enter the warehouse until they are shipped. 

1. Real-Time Tracking 

Gone are the days when inventory was tallied manually in extensive spreadsheets, prone to errors and inefficient data retrieval. In today’s real-time world, WMSs offer live tracking capabilities that pinpoint each item's location and provide insights into order status, shipping, and other logistics, such as potential delays.

2. Documentation 

Proper documentation is essential for regulatory compliance and smooth operations. Modern WMSs automate this process, integrating it with broader systems to ensure consistency across business operations.

3. Warehousing 

From space utilization to the arrangement of goods, WMSs apply data-driven algorithms to optimize warehousing operations. This approach ensures that each square foot is optimally utilized, directly impacting the bottom line.

Types of Warehouse Management Systems

As with any technology, Warehouse Management Systems come in various forms, each designed to address specific business needs. In general, you can think of these as representations of the complexity, scope, and breadth of your business’s logistical operations. 

Standalone WMS

These are best suited for smaller operations that don’t require intricate features or multiple integrations. They handle basic tasks like inventory tracking and documentation but lack the robust capabilities of integrated systems.

WMS Integrated with SCM

These modular WMSs have been integrated into a more extensive Supply Chain Management digital system (SCM). These are good options for businesses that must manage their warehouse operations in conjunction with other supply chain sectors, including transportation, inventory management, etc.

Integrated WMS to ERP

These are integrated solutions for larger, more complex enterprise operations. Under one umbrella, they bring an arsenal of capabilities, including supply chain management, human resources, and financial planning.

Cloud-based Systems

The Cloud-based WMS offers the best of both worlds: functionality and scalability. It provides the flexibility to adapt to changing business conditions without the need for substantial investment in hardware.

Levels of WMS Complexity: From Basic to Controlled Systems

In the ever-evolving landscape of warehouse management in the age of Industry 4.0 and the Industrial Internet of Things (IIoT) devices, it's crucial to understand the different tiers of WMS solutions available. Here's how they generally differ in terms of features and functionalities:


A WMS primarily focuses on inventory control and location management at its most rudimentary level. Regarding analytics, the scope is often confined to tracking 'throughput,' quantifying the volume of stock flowing through the warehouse within a specific timeframe. It's worth noting that a basic WMS is virtually indistinguishable from an elementary Inventory Management System in both functionality and scope.


An elevated level of WMS capability involves not just inventory and location tracking but also scrutinizes warehouse capacity and stock levels. These systems are also adept at time and labor allocation analysis. Consequently, they generate data that can be instrumental in assessing efficiency and proposing actionable insights for improvement. 

Most WMS solutions deployed (outside East Asia) belong to this category. At this advanced tier, the roles and responsibilities of a WMS might merge with or even eclipse those of Warehouse Control Systems or Warehouse Execution Systems.

Venturing into the realm of controlled WMS solutions introduces a highly complex and integrated approach. These systems can exchange data with external platforms handling non-warehouse-based data, thereby incorporating information beyond the confines of the warehouse itself. 

For example, it can adapt its operational strategy based on external elements like manufacturing requirements, customer orders, and other logistics systems. Moreover, in technologically advanced facilities equipped with automation or advanced IIoT capabilities, a controlled WMS can influence and gather insights from these devices. Some may even incorporate machine learning algorithms to simulate or evaluate strategies for operational optimization perpetually.
