How to Choose an Open Source Warehouse Management System

With so many different open source warehouse management systems available, it can be challenging to make decisions on what open source warehouse management system is going to be the best fit for your needs. As you're shortlisting, trialing, and selecting open source warehouse management systems, consider the following:

  • What problem are you trying to solve - Start by identifying the warehouse management feature gap you're trying to fill to clarify the features and functionality the open source warehouse management system needs to provide.
  • Who will need to use it - To evaluate cost and requirements, consider who'll be using the software and how many licenses you'll need. You'll need to evaluate if it'll just be the ecommerce team, or the whole organization that will require access. When that's clear, it's worth considering if you're prioritizing ease of use for all, or speed for your ecommerce software power users.
  • What other tools it needs to work with - Clarify what tools you're replacing, what tools are staying, and the tools you'll need to integrate with, such as accounting, CRM or HR software. You'll need to decide if the tools will need to integrate together, or alternatively, if you can replace multiple tools with one consolidated open source warehouse management system.
  • What outcomes are important - Consider the result that the software needs to deliver to be considered a success. Consider what capability you want to gain, or what you want to improve, and how you will be measuring success. For example, an outcome could be the ability to get greater visibility into performance. You could compare open source warehouse management system features until you’re blue in the face but if you aren’t thinking about the outcomes you want to drive, you could be wasting a lot of valuable time.
  • How it would work within your organization - Consider the software selection alongside your workflows and delivery methodology. Evaluate what's working well, and the areas that are causing issues that need to be addressed. Remember every business is different — don’t assume that because a tool is popular that it'll work in your organization.
