3 Free and Open Source ERP Software

Jump to:


For most organizations, enterprise resource planning (ERP) is a critical tool as it offers complete visibility into important aspects of the business. It gives the senior management a single-window view to monitor organization-wide data.

There are several paid and proprietary ERP tools available on the market. Depending on the vendor, each tool’s capabilities would vary, but mostly all are very robust. But should you always pay to use one?

In some cases, your needs may be too simple to justify paying for an ERP solution. Or you may have never used an ERP system before and want to make sure investing in one is worthwhile. That’s where free or open source ERP software solutions help.

Such ERP tools cost nothing to use and you can upgrade to a paid version to access additional features when you scale. Below, you’ll find three free and open source software tools and learn how much each costs to upgrade. These tools (arranged alphabetically) have been picked from the 2021 Capterra Shortlist for ERP software. (See full selection methodology here.)

How to choose the right free and open source ERP tool for your business

These considerations can make selecting a free and open source ERP system a little easier:

  • Look for a scalable solution. As your business grows, you’ll need to handle more business units, more data, and more complex operations.
  • Compare the free usage limits of the products (such as the number of users and available features) and shortlist tools accordingly.

Common questions to ask while selecting a free and open source ERP tool

You’ll probably have certain concerns when selecting a free and open source ERP system. Here are a few key questions to consider asking the ERP vendor:

  • How frequently do you release new updates? The answer to this will help you gauge how active the vendor is in maintaining and improving their ERP software. If the vendor hasn’t released any update or a new feature in a while, this can be a sign that the ERP tool may soon become outdated.
  • Will I need additional training to use the tool? Check with the software provider how complex the ERP tool is. Ask if you’ll need additional training to get familiar with its features and if this training will cost you extra.
  • Does the software upgrade cost include phone-based tech support? This will help you get clarity on the type of premium support you’ll receive when you start paying for the ERP tool.
