Warehouse Management Systems: What You Need To Know

Warehouse Management Systems

A Warehouse Management System (WMS) is a software tool that assists warehouse operators and third-party logistics providers (3PLs) in managing and tracking inventory, orders, and deliveries. A WMS automates tasks such as monitoring inventory levels, optimizing storage layouts, and creating pick lists, which enhances a business’s efficiency and productivity.

The significance of warehouse management systems (WMS) has grown recently due to the increase in online shopping, mobile phone and internet usage, and the pandemic, which has accelerated the need for automated solutions for online businesses. While WMS can be used in small and large warehouses, they become particularly advantageous in spaces larger than 20,000 square feet where operations become more complex.

With eCommerce, growth predicted to increase the global warehouse automation market by €24.8 billion (10.41% CAGR) by 2026, along with the challenges of managing multi-channel listings and courier services, modern WMS solutions are now essential for warehouses, 3PLs, and eCommerce retailers to stay competitive.

Warehouse management is a vital part of the supply chain, handling the storage and movement of materials essential for business operations. This encompasses receiving, storing, and shipping goods, along with managing inventory levels and stock locations. The efficiency and accuracy of the supply chain are directly tied to the effectiveness of warehouse processes. Ineffective warehouse management can disrupt material flow and impede business functionality.

Warehouse Management Systems (WMS) are often used alongside or integrated with other systems like Enterprise Resource Planning (ERP) systems, order management systems, or Transport Management Systems (TMS), such as shipping management software.WMSs are crucial for operations in warehouses and distribution centers, including picking items for shipment and storing received goods. They use data from barcode readers and RFID tags to keep the ERP system updated with the latest inventory information, ensuring synchronized data between the WMS and ERP. The ERP system covers tasks from accounting and invoicing to order and inventory management, while the TMS manages shipping processes.

The TMS stores detailed carrier information and serves as a communication system for planning, executing, and tracking shipments. Integration of TMS with WMS can enhance coordination of inbound and outbound logistics tasks. Orders are generally imported automatically from ERP or order management systems linked to the TMS, including customer details and item information for accurate shipments. The TMS then provides shipment details (such as tracking information, carrier name, and cost) to the ERP system for accounting and order management. This information may also be sent to the Customer Relationship Management (CRM) module to update customers’ order status.

Types of WMS

There are 4 Major Types of WMS:

1. Standalone System

A standalone system is an on-site software typically installed directly on a business’s local hardware. It provides essential features necessary for efficient day-to-day warehouse operations and inventory management. While standalone WMS systems differ from provider to provider, they consistently offer core functions such as:

  •  Inventory tracking
  •  Picking and packing
  •  Shipping
  •  Returns

However, standalone systems may only sometimes support broader functionalities, making them better suited for small warehouse operations with limited budgets and fewer dependencies, such as extensive integrations. For businesses planning significant growth shortly, investing in a more robust warehousing management system may be advisable.

With its primary focus on warehouse management, a standalone system often includes advanced features that streamline various processes. For instance, a small local electronics retailer relies on a standalone WMS to efficiently track inventory, streamline picking and packing processes, and handle shipping and returns.

Standalone systems may lack broader functionalities making them more suitable for small warehouse operations with limited budgets and integration needs.

2. Cloud-Based System

In the past, WMS software was often purchased and delivered as physical media like disks or CDs. In this day and age, cloud-based warehouse management systems have become popular due to their ease of implementation, scalability, enhanced security, and flexible, customizable features.

A cloud-based WMS is a web-based solution hosted on external servers and supported by an external IT team. This eliminates the need for on-site installation and complex integration with existing systems, making it an excellent choice for many businesses. For example, Amazon, a leading e-commerce company, uses cloud-based WMS solutions to manage its extensive warehouse operations efficiently without the need for extensive on-site setup.

Cloud-based systems require no on-site installation or complex integration with existing systems. When upgrades are necessary, the WMS vendor handles them, preventing downtime. For instance, Shopify, an online retail platform, utilizes a cloud-based WMS to manage inventory and shipping processes. When the system needs an upgrade, the vendor takes care of it, allowing Shopify to continue operations without interruption.

With a cloud-based system, the SaaS provider controls the maintenance and improvements of the entire WMS. If a company prefers full control over its system and data, a standalone system might be more suitable. For example, Boeing, with strict data security requirements, might choose a standalone system to maintain complete control over their warehouse management processes.

3. Supply Chain Modules
