What Is Open Source ERP Software?

Open source ERP software is an enterprise resource planning system with a source code anyone can inspect, modify, or enhance. This lets users and businesses create and customize software as they see fit rather than pay for these services through a software vendor. Typically available for free, open-source ERP software is significantly more cost-effective than proprietary or closed-source programs.

Open source ERP software includes all of the needed functionality that regular ERP software has. This includes invoicing, inventory management, sales management via eCommerce platforms, human resources, and project management. Yet companies with open source ERP gain more control over their IT investment and get insurance against vendor inattention.

Is Open Source ERP Software Really Free?

If an ERP solution is advertised as open-source, the source code is 100% free. Once installed, you’ll have full access to the software at no cost.

To better illustrate the difference between free, open source, and paid options, you can view our table below:

Free Open Source Paid
Description: Simple, reduced version with limited features Source code is made publicly available Licensed and bought from a software provider
Target Market: Start-ups and small businesses Knowledgeable IT departments Medium to large businesses
Advantages: Free Community-backed Robust features
Disadvantages: Limited functions Requires a higher level of IT knowledge Expensive to implement and maintain

Some open source software developers offer paid versions with additional functionality. There might also be additional costs for adding new users or increasing data storage. However, the source code will still be free.

Other costs an open source ERP software might have include:

  • Implementation fees: Setting up the software correctly may require the assistance of the developer or IT consultants.
  • Deployment method: On-premise implementation can require new hardware to run. A cloud-based deployment can cost around $40 per month for a VPS.
  • Support: Maintaining the ERP can lead to costs from in-house IT teams or hiring outside specialists.

Benefits of Open Source ERP Software

There are many benefits to using open source ERP solutions over some well-known ERP options like Oracle or SAP. It’s usually available for free or at a significantly reduced cost. A free ERP system can provide major savings to businesses of all sizes.

Other top benefits include:

Freedom from Licensing

The main reasons companies prefer open source enterprise resource planning software are lower costs and ease of customization. These benefits come from a lack of licensing usually found in a commercial ERP system.

Open source ERP software systems use open source databases and operating systems, making it a license-free option. Commercial systems may require the use of expensive commercial databases and operating systems. Open source ERP software means you don’t need to rely on proprietary software, which may not be as open to product development ideas.

Community Support

Since open source ERP systems are developed by a community, they rely on input from users, which usually come from passionate developers. In-house IT departments can benefit from having a community-driven support network. While very new and experimental, IT professionals can use the community to solve problems instead of relying on the vendor to solve software issues at a high cost.

Fully Customizable and Scalable

The flexibility of open source ERP software remains one of the top reasons to consider using one. Access to the source data allows developers to improve existing code. These improvements are usually shared within a community and made easy to implement. It also allows your in-house users and participants to modify and redistribute the underlying source code at will. Overall, open source ERP systems are far easier to upgrade and scale.

The best benefit of heavy customization capabilities is that the software can be fine-tuned to your organization’s needs. Any changes to the program code or added functionalities created by the development community also help save costs on paying a commercial software provider to custom-create that feature for you.

Drawbacks of Open Source ERP Software to Consider

Implementing an open source ERP system isn’t without certain drawbacks. Your business must weigh the pros and cons equally to determine if open source ERP software is right for you.

Security Concerns

A common misconception with open source software is the perceived lack of security. This can cause concerns when housing sensitive financial data in the system. Fortunately, the availability of source code has no impact on the operational security of the software. Because of this, open source ERP is no more or less secure than a commercially developed ERP system. However, as the purchasing company is usually responsible for both the implementation and further development of the system, open source ERP can be considered a slightly more risky option in case of errors or system failures.

Limited Support

Community-supported products will only be as successful as the community size allows for. Using a lesser-known option will yield fewer results when looking for troubleshooting assistance. If a company doesn’t buy a support plan from a provider, you’ll have to rely on your internal IT staff or the volunteer community, which poses uncertainty in a major system failure. If a company does buy a support plan from a provider, it may also be instead of a package deal with other advanced features, proprietary modules, or training, which could be just as sizable of an investment as what you would get with a normal ERP software.

No Easy Installation or Training Process

While open source ERP does not require any substantial licensing costs, it could still result in higher IT costs if you are making your own customizations in-house. If not, you must pay a developer to make the needed changes. And if you don’t pay for professional training, you’ll be looking to educate your entire staff solely on documentation found online and through support communities, which may slow down your implementation process.
