ERP, or enterprise resource planning, is a holistic software suite used to manage a business’s operations. An ERP is meant to integrate many company systems to increase efficiency and productivity. Investing in a robust ERP system is a time-consuming and costly process. As a result, many businesses have to change their internal workflow and business processes to implement ERP. Despite the high cost and lengthy implementation process, companies must select the appropriate open source ERP software to automate processes and boost productivity.

This blog will cover all you need to know about the open source ERP system and how it works. Additionally, we will examine some of the top open source ERP software currently available on the market.

What is Open Source ERP?

In comparison to proprietary software, open-source enterprise resource planning (ERP) systems provide greater control and flexibility. Due to the lack of source code in proprietary software, customers must rely entirely on the vendor’s offers or pay a premium for unique features. However, customers of open source ERP software have access to the source code and can alter it to match their own needs.

Open-source enterprise resource planning software has a lower total cost of ownership. Additionally, ERP software is available to the general public (with some catches). There is, however, no licensing fee, and users of the open source ERP system have free access to the source code. The majority of credible and established open source ERP vendors charge an additional cost for ancillary services such as hosting, support, and enhanced capabilities (more on this later).

Pros and Cons

Open source ERP — software that is freely available, adaptable, and publicly accessible – sounds like a dream. While it undoubtedly has numerous advantages, it also has drawbacks. We’re going to discuss and explain the advantages and disadvantages of open source ERP software below.


Low Cost

As indicated previously, there are no license fees associated with the source code download. As a result, self-hosting your open source ERP system without vendor support is entirely free. For those who dont want to manage their system altogether, a vendor offering software-as-a-service (SaaS) solutions can be found. They are typically billed monthly, and the cost will vary depending on the services you choose and the number of users.

Highly Scalable

When defining your requirements for ERP software, it’s critical to consider the future state of your buisness. This is because adding features or the number of users in the future can cost development or reimplementation if you didn’t select the right open source ERP from the start. Our personal favorite is ERPNext. It works with most size businesses. However, because an open-source system is scalable, a growing organization can adjust to its ERP system as needed.

Access to Open Source Communities

Numerous open-source platforms are backed up by solid user communities – support that is both experimental and transparent. Open source might be an attractive option for IT workers that enjoy being engaged in this environment. These communities are well-known for their rapid response to system faults, the sharing of pre-built customizations or modules, and much more.


Requires Knowledgeable IT Team Or and Open Source ERP Consulting Company

With an open source ERP implementation, you take on the role of the project’s software specialist. This obligation is a significant obstacle, and it might instantly dissuade businesses lacking tech-savvy personnel from giving these solutions a try.

Overly Complex

By their very nature, all ERP implementation projects are challenging, but open-source implementations can seem overly complex. Without a clear plan in place, available adaptations can quickly spiral out of control and become unproductive.

Potential for Increased Risk

Today, highly established and financially solid open-source software vendors are few on the market. Some may view working with startups as a commercial risk.
