Types of WMS Systems & Their Role in Supply Chain Management

Every day, millions of products are stored, packed, and shipped from warehouses across the globe. While we, as customers, are mostly concerned with getting the orders delivered on time, businesses have to look after countless moving parts behind the scenes to make those deliveries possible.

When manually dealing with inventories and orders this huge and varied, operational setbacks in the form of stock misplacement, fulfilment errors, and more are bound to arise.

That’s exactly why businesses, today, are turning to Warehouse Management Systems (WMS). These software solutions automate everyday warehouse operations in order to keep the inventory orderly and as its direct consequence, orders flowing.

The best part? There are different types of WMS systems available in the market to meet different business needs. Let’s explore them one by one and while at it, also shed light on the key role they play in making the supply chain more productive.

What is a Warehouse Management System (WMS)?

A warehouse management system is a supply chain management tool that, as the name implies, helps businesses manage their routine warehouse tasks more conveniently. To attain the same, it provides businesses with a clear picture of their inventory and stock movement in real time.

The software also supports receiving, storage, packing, and shipping of deliverables to speed up the fulfilment process. In doing so, it helps reduce manual errors, better manage stock levels and warehouse space, all of this and more to ensure orders reach customers on time.

Types of WMS Systems

Different businesses have different needs. One warehouse management system therefore cannot serve every warehouse equally. This is why different types of WMS systems exist, so businesses can choose a solution that best fits their operational needs and budget.

We have listed some of them below for your convenience…

Core Types of Warehouse Management Systems

1. Standalone WMS

A Standalone Warehouse Management System (WMS) is a software solution programmed to manage warehouse operations. It focuses primarily on what happens inside the warehouse, be it receiving inventory, storing it, keeping track of it, packing it when the times comes, or shipping it to its final destination.

The system also often connects with other business applications, such as accounting, ERP, and eCommerce platforms, but warehouse management remains its core function.

Key Characteristics of Standalone WMS:

• Is built specifically for warehouse and inventory management
• Tracks inventory in real time

The Role of WMS in Supply Chain Management

Here’s everything that a warehouse management system does to make the entire supply chain fast and more reliable…

• Better Visibility of Inventory: With a good WMS in place, businesses get a clear picture of their inventory. They get to know what products are available and where they are stored. This helps them decide how much to order, so they don’t stock in more than what’s necessary or run out of stuff when needed.
• Faster Order Processing: With the help of a warehouse management system, orders, as and when they come, can be quickly picked, packed, and shipped. This reduces delays and helps customers receive their orders sooner.
• Fewer Mistakes: Wrong shipments, missing products, and inventory mismatches can be costly. By keeping track of stock movements in real time, a WMS helps reduce errors that come with manual tracking.
• Smarter Use of Warehouse Space: When you have a reliable WMS in place, it becomes easier to decide where to store products for easy access. This not only keeps the warehouse organized but also makes certain you make good use of all the available space.
• Higher Employee Productivity: A WMS makes sure workers spend more time on fulfiling orders and not searching for products, making the supply chain more efficient.
• Improved Customer Satisfaction: When customers get their orders on time, they are bound to be satisfied and come back for more. All thanks to WMS, businesses can achieve this feat, and how!
• EasiBusiness Growth: As a business grows, its operations become more and more complex. With the help of a warehouse management system, businesses can handle this complexity and growth in demand more easily by exercising greater control over inventory and workflows.
• Stronger Supply Chain Coordination: WMS platforms allow integration with inventory, transportation, and order management systems. This ensures everyone involved in the supply chain works with the same up-to-date information.
