I mentioned two of the most popular software options for warehouse management: WMS and ERP systems. These systems have some overlap, and the terms are even sometimes used interchangeably, but they’re not the same. It’s important to understand exactly what each system is designed to do. In this article, we’ll go into detail about WMS vs ERP, including some strategies on how to pick the right one for your business.

What are WMS Systems? 

A warehouse management system, also known as a WMS, is a type of software businesses can use to better manage and optimize their warehouse operations. These systems give businesses real-time visibility into their inventory as long as it is within the four walls of the warehouse. So how does a WMS work? As each item in your warehouse is received, stored, picked, packed, and shipped out, a WMS seamlessly tracks it for you.  


i. Faster to Implement 

Because a WMS focuses solely on one area of your business — inventory and warehouse management — it’s quicker to implement than broader solutions like ERPs.  

ii. Designed for Comprehensive Inventory Management 

A WMS is a sophisticated tool that can help you manage complicated warehouse management processes. Different types of warehouse management systems offer specific, advanced features and can automate repetitive warehouse tasks.  


i. Isolation from Other Areas of Your Business 

The specialized nature of a WMS offers some advantages over more general solutions like ERP systems, but it can also lead to your warehouse data being isolated from other functional areas in your business. You’ll have to integrate the WMS with a broader solution for easy cross-department information flow.  

ii. Only Includes Warehouse Operations Features 

Unlike an ERP system, a WMS cannot help you manage supply chain activities outside the warehouse or business functions like accounting.

What are ERP Systems? 

Enterprise resource planning systems, or ERP systems, have a broad scope and allow companies to manage multiple business functions from one platform. These systems utilize integrated sets of modules, each dedicated to a different business process. They’re designed to automate processes across departments rather than focusing on just one. 

Some examples of the functions you can track and optimize in ERP systems include: 

  • Finance and accounting 
  • Customer relationship management 
  • Procurement 
  • Order entry and processing
  • Inventory and warehouse management 

When you use an ERP system, information from each of these processes can easily flow between functional areas of your business. As you may notice, most ERP systems include some warehouse management functionality.   


i. Offer a Centralized All-in-one Solution 

With an ERP, you can manage many departments from one central solution. This makes it easy for employees across departments to access key business information in the system.  

ii. Can Help Streamline Your Whole Business 

Instead of focusing on only one functional area, you can use an ERP system to streamline many different regions of your business.


i. Strong Learning Curve 

Because ERPs connect to many business areas, there’s a steep learning curve to understanding and using the application effectively. It will take considerable time and effort for your employees in each department to get used to using the new ERP.

ii. Less Detailed Warehousing Controls

The WMS portion of an ERP system is much less comprehensive than a standalone WMS. You won’t get the same breadth of warehouse controls and inventory management insights with an ERP.

How to Choose WMS vs ERP for Your Business 

WMS and ERP systems can both be incredibly useful for a wide variety of businesses. Instead of asking which is better in general, you should ask yourself which is the best option for your business. When you’re trying to decide between ERP vs WMS for your business, consider these five important factors: 

i. Type of Business 

The type of business you run is highly relevant to your decision of adopting a WMS or ERP system. If you have comprehensive warehouse processes in your business, a warehouse management system is likely the better option than ERP. If you only have basic warehouse processes, an ERP system would probably offer enough warehouse management features for your needs.  

ii. Your Motivation for Purchasing the Software 

During the decision-making process, you should also ask yourself why you want to purchase one of these types of software. Are you looking specifically to streamline your warehouse operations? If so, a WMS is the best choice. However, if you’re more interested in streamlining processes across your business, including the warehouse, an ERP system is more appropriate. These systems are designed to operate in many functional areas of your business, not just the warehouse.  

iii. Your Long-Term Business Goals

Whenever you’re thinking about purchasing new software or tools for your business, you need to consider your long-term business goals. These tools may not offer an immediate return on investment, so you have to look toward the future to ensure you pick a solution that fits your goals for the company over the long term. Focusing only on your immediate needs and goals could lead you to overlook the best overall solution for your business.  

iv. Your Budget

Generally, implementing an ERP system is more expensive than putting a standalone WMS into place. ERP systems work across many different business departments, and you’ll have to connect processes in each of those departments to the system. The whole implementation process is costly and time-consuming for your business. And if you ever need to add additional modules to your ERP system as you scale your business, that will only drive the cost up further.  

By comparison, implementing a WMS is typically a more affordable option than ERP. With a WMS, you only have to worry about connecting your warehouse operations to the system.  

v. Your Existing Systems and Processes 

With either a WMS or ERP system, you’re introducing a new system that will have to integrate well into your existing systems and processes to be useful. Consider your existing warehousing and inventory processes to decide which type of system will work best with what you already have.  

Final Thoughts 

Depending on your needs and goals, either a WMS or ERP system may be the best choice for your business. A WMS is a more specialized application focused on helping you manage warehouse operations. An ERP system, by contrast, is a broader tool with applications across departments. Choosing the right software for your business can ultimately improve efficiency and cost.
