This software typically offers cost advantages and flexibility, supported by a community of developers and users.

Benefits of Open Source HR Software
There are sprawling lists of HR software to choose from; so, why choose open-source? Open-source HR software offers numerous benefits for users and organizations. Here are several reasons why you might want to implement open-source HR software in your organization:
- Cost-Effective: The most common benefit of using open-source software is that it's free. By eliminating the high licensing fees associated with proprietary systems, an open-source system reduces overall operational costs for your business.

By choosing open-source HR software, businesses can save on costs and gain the flexibility and control needed to create a system that perfectly suits their needs.

Costs & Pricing for Open Source HR Software
Sometimes it all comes down to price, and open source software is generally very affordable. In fact, in most cases, the software is available to use for free.
Many open-source providers also offer users the option to scale up to a paid version of the same software if you want to access more advanced features. Having that kind of flexibility is great as a user. It means you can download it and spend some time getting comfortable with it before making your decision.
And if you really love it, and want to access more features, you can either scale up, or ask your IT department to try and customize it for your own unique business needs.
Frequently Asked Questions
Here are some answers to frequently asked questions I often hear about open-source HR software:
What does "open source" mean in relation to software?
The term open source refers to a type of software development and distribution model where the source code of a computer program is made available to the public. With that information publicly accessible, other software developers can modify the underlying source code to customize the application for their own specific needs. Open source software is typically developed collaboratively within technical communities of developers who work on the project pro bono (i.e., for free) in order to advance the project along for the greater good of the industry and end users.
What is the difference between HRIS and HRMS?
Human Resources Information Systems (HRIS) are software that offer more basic functions like attendance, time tracking, and payroll processing. Human Resources Management Systems (HRMS) are employee management tools that take functionality a step further by including features like reporting, employee engagement, and performance appraisal.
What software integrations are important for open-source HR software?
Software integrations can save you a lot of grunt work, such as needing to transfer data manually, or via imports and exports, from one system to another. Instead, using native software integration, you’ll be able to improve your team’s productivity and help your HR professionals work more efficiently.
The specific integrations to look for will depend on the type of HR software you’re after, however, integrations with email providers, digital calendars, payroll software, and work platforms like Google Workspace and Microsoft SharePoint are always welcome.
