Top 15 Free and Open Source ERP Solutions

Top 15 Free and Open Source ERP Solutions

Searching for ERP software can be a daunting (and expensive) process, one that requires long hours of research and deep pockets. The most popular ERP systems often provide more than what’s necessary for non-enterprise organizations, with advanced functionality relevant to only the most technically savvy users. Thankfully, there are a number of free and open source ERP solutions out there. Some of these solutions are offered by vendors looking to eventually sell you on their enterprise product, and others are maintained and operated by a community of developers looking to democratize ERP.

In this article we will examine free and open source ERP software, first by providing a brief overview of what to expect and also with short blurbs about each of the currently available options in the space. This is the most complete and up-to-date directory on the web.

Free ERP solutions defined

Free ERP software refers to products that are offered commercially free by the solution provider. These offerings are usually trimmed-down versions of the expert or enterprise editions, offering basic functionality that enables users to generate reports or data visualizations. Commercially free ERP tools typically offer less functionality on the whole than their open source counterparts, but are often a great way to gain more than a free trial if its a product you were already considering.

What is open source ERP?

Open source ERP is software with a source code that anyone can inspect, modify or enhance. These tools are designed to be publicly accessible and are commonly managed and maintained by organizations with a specific mission in mind. The open source ERP solutions included in this list are surprisingly full-featured, offering an expansive list of capabilities for a variety of users.

It’s important to remember that some of the open source offers included in this list require some development skills, and that may make them less than ideal fits for your use case. We recommend that you read each tool’s FAQ to see just how much coding is required to take advantage of the software. The open source tools usually do a good job of explaining the requirements for use on the download pages.
