What is WMS for eCommerce? All You Need to Know

In the fast-paced realm of eCommerce, competition is fierce and there’s little room for error. Ensuring customer satisfaction and efficiently managing operations are crucial for the success of any eCommerce business. While often overlooked, one key factor that significantly impacts success is having a reliable and effective Warehouse Management System (WMS). 

What is a Warehouse Management System?

A Warehouse Management System (WMS) specifically tailored for eCommerce is a specialized software platform that handles all aspects of warehousing operations. Think of it as the conductor behind the scenes, skillfully managing inventory movements to ensure that each product or SKU reaches customers promptly and smoothly. The WMS software provides a comprehensive framework to oversee various stages, starting from receiving goods into the warehouse all the way to order dispatch. This includes tasks such as product storage, order processing and even tracking orders throughout their journey.

Why are Warehouse Management Systems Important?

Understanding how WMS empowers eCommerce businesses is essential for navigating this competitive landscape successfully. Warehouse Management Systems (WMS) play a crucial role in the world of eCommerce, acting as a control tower for every movement within the warehouse. They offer: 

  1. Inventory Management: A WMS allows you to monitor and control your inventory levels in real-time, preventing overstocking and understocking scenarios. This translates to cost savings and improved order efficiency.
  2. Efficiency and Accuracy: Warehouse management systems enhance the efficiency and accuracy of warehouse operations, reducing errors in order fulfillment and, in turn, reducing inventory shrinkage.
  3. Customer Satisfaction: An efficient WMS ensures that products are readily available and orders are processed promptly, leading to quicker deliveries and higher customer satisfaction.
  4. Order Management: With a WMS, order management becomes seamless. It provides real-time order tracking, streamlining order processing, and ensuring that your goods reach your clients swiftly and accurately.
  5. Data-Driven Decision Making: WMS software offers comprehensive data about your inventory and order management. This information empowers eCommerce retailers to make data-driven decisions to further streamline their operations and services.
  6. Scalability: As your eCommerce business grows, the complexity of your warehouse operations will increase. A WMS system can scale along with your business, making it easier to manage larger inventories, more customers, and an increased flow of orders.

A robust WMS is more than just a tool to manage your eCommerce warehouse or distribution center. It’s an essential system that helps improve service to your customers, providing you with a competitive edge in the highly competitive marketplace. 

Key Components of a Good Warehouse Management System

A well-functioning WMS should have several key components to streamline your warehouse operations and support your eCommerce business needs:

  1. Integration Capabilities: The WMS should integrate seamlessly with your eCommerce platform, whether it’s Shopify, WooCommerce, or any other. Moreover, it should also integrate with other essential systems such as ERP (Enterprise Resource Planning), EDI (Electronic Data Interchange), and shipping carriers to streamline the supply chain operations.
  2. Inventory Control: An effective WMS provides complete visibility into your inventory, enabling real-time tracking of stock levels at different locations. It helps in maintaining accurate inventory data, avoiding overstocking or stockout situations, and ultimately reducing storage space and costs.
  3. Order Management: A comprehensive WMS aids in efficient order fulfillment, from picking, packing, to delivery. Some systems offer batch-picking functionality, further improving order processing speed and efficiency.
  4. Analytics and Reporting: Your WMS should provide insightful reports and analytics, giving you crucial information about your operations, such as performance metrics, shipping costs, and other essential data. These insights can guide your decision-making process, helping to optimize processes and increase profits.
  5. Scalability: The WMS should be scalable to accommodate your business’s growth and evolving demands. Whether you’re expanding your product range or increasing the number of orders, the system should seamlessly scale with your needs.
  6. Ease of Use: The user interface should be intuitive, ensuring your warehouse staff can easily navigate the system. The easier the system is to use, the less time your staff will spend on training and the more time they can dedicate to core tasks.

Types of Warehouse Management Systems

Standalone WMS

A standalone WMS is a traditional form of warehouse management software that operates independently from other systems in your business. It is often a cost-effective option and can be tailored to meet the specific needs of your warehouse operations. However, integration with other systems like ERP or eCommerce platforms might require additional investments.

Integrated WMS

An integrated WMS is typically part of a larger software suite, like an ERP system. It is designed to work seamlessly with other business processes, from order management to transportation and logistics. While an integrated WMS might require a larger upfront investment, it often leads to increased efficiency and accuracy by unifying all operations under a single platform.

Cloud-based WMS

Cloud-based WMS systems have gained popularity in recent years due to their scalability and flexibility. They are hosted on the vendor’s server and accessed via the internet, often through a browser or an Android app. This model reduces the need for a large upfront hardware investment and offers the flexibility to access the system from anywhere. Additionally, updates and maintenance are typically handled by the provider, making it an attractive option for many eCommerce businesses.

On-site WMS

An on-site or ‘on-premise’ WMS is a system installed directly on the company’s servers and managed by the company’s IT staff. It often requires purchasing hardware such as servers and barcode scanners and a significant upfront investment. However, it offers complete control over the system, which can be beneficial for companies with specific security or customization requirements.

Benefits of a Warehouse Management System For eCommerce

More Accurate Inventory Counts

A robust WMS equips you with advanced features and functionalities to maintain accurate inventory counts. Automation plays a pivotal part in this process, reducing the risk of human error and ensuring that you always have an accurate view of your stock levels. For instance, suppose a customer adds an item to their shopping cart on your eCommerce platform. In that case, the WMS automatically updates the inventory count, ensuring that your stock levels are accurate in real-time.

Better Order Efficiency

WMS enhances your order efficiency, offering methods and techniques that streamline every step of your order fulfillment process. From the moment a customer submits a request form or adds an item to their shopping cart, to the point where the order is packed and shipped, the WMS is there to ensure the process runs smoothly. 

More Productive Warehouses

By automating numerous tasks within the warehouse, WMS frees up time for your warehouse staff to focus on other essential operations. For example, with a WMS, users no longer need to spend hours manually counting stock. Instead, the system does it for them, allowing them to allocate their time to more value-adding activities, thus making your warehouses more productive.

Less Cost

Investing in a WMS may seem like a significant upfront cost. However, it’s important to look at this as a long-term investment. By improving order efficiency and reducing errors, WMS can save you a considerable amount of money in the long run. Plus, by providing accurate inventory data, a WMS helps prevent overstocking and understocking situations, further reducing your costs.

Enables Faster Shipping

Speedy delivery times are a crucial part of a positive customer experience, and a WMS helps by streamlining your order fulfillment processes and enabling faster shipping. And, many WMS solutions can integrate with various shipping carriers, allowing you to choose the most efficient shipping method for each order.

How to Choose the Ideal Warehouse Management System for Your eCommerce Business

Accuracy of Information

A good WMS should provide accurate and real-time data about your inventory, supply chain, and order status. This visibility into your operations is vital for making informed decisions and optimizing your workflows. Look for a system that minimizes errors and offers features like barcode scanning for accurate data entry and tracking.


Implementing a new WMS will involve a learning curve for your staff. Consider the training support provided by the WMS vendors. Will they assist with onboarding? Do they offer comprehensive training resources? Remember, the easier the system is for your team to use, the quicker you’ll see a return on your investment.


As your eCommerce business grows, your WMS should be able to scale with it. This means being able to handle increasing inventory levels, more complex fulfillment operations, and integration with additional tools or services. Evaluate your potential WMS options for their scalability to ensure they can support your growth.

Return on Investment

While it’s essential to consider the upfront costs of a WMS, don’t lose sight of the long-term value it brings. Features like improved inventory control, increased order accuracy, and better warehouse efficiency can lead to significant cost savings over time. Analyze your options for their potential return on investment, including cost savings and improvements in customer satisfaction.

On-site vs Cloud-based

On-site and cloud-based WMS options each have their pros and cons. On-site systems may offer more control and customization options but require a larger upfront investment and ongoing maintenance. On the other hand, cloud-based systems are typically more scalable and have lower upfront costs but depend on a reliable internet connection. Consider your business’s specific needs, budget, and IT resources when deciding which option is best.


Integration with your existing systems, such as your eCommerce platform, shipping services, and 3PL providers, is a critical factor to consider. An integrated WMS can streamline your operations by allowing data to flow seamlessly between different parts of your supply chain. Check what integrations each WMS option offers and how easy it is to set them up.

Implementing WMS for eCommerce Fulfillment

Evaluating Your Current System

Before choosing a new WMS software, you must first assess your current system. Are there any shortcomings that need to be addressed? Do you need better visibility into your orders, inventory, and shipments? This initial evaluation should also include an analysis of your current order processing, order tracking, and order fulfillment systems. 

Collecting Team Needs

Involving your team in the decision-making process is a key part of implementing a new WMS. Collect input from different areas of your operations, including order management, shipping, and customer service. By understanding their needs and challenges, you can find a WMS that not only improves operational efficiency but also enhances customer satisfaction and makes life easier for your employees.

Finding and Evaluating Vendors

There are various WMS providers to choose from, each offering different features, functionalities, and pricing models. When evaluating vendors, it’s important to consider how well their platform integrates with your existing systems, including your eCommerce platform, whether it’s Shopify, WooCommerce, or another service. Look for a WMS that can handle your business’s unique needs, from managing individual SKUs to tracking complex shipments.
