Difference Between Open-Source and Free ERP

Now that you’ve seen the best open-source ERP, let’s talk about the difference between open-source and free ERP.

Open-source ERP is a system that allows you to tailor its coding with features and attributes to meet your company’s needs.

Free ERP is a solution that doesn’t have any licensing or upfront fees attached. The source code isn’t readily available, either.

Virginia Miller, marketing coordinator for Simpl Fulfillment, described the advantages of open-source ERP.

Distinct from free ERP, open-source ERP is essentially a treasure trove of coding that businesses manipulate to suit their operations, while free ERP is basically what you see is what you get. In terms of customization authority, open-source ERP really shines. By allowing businesses to experiment with and modify the source code, they can bring about bespoke solutions that align perfectly with their processes.”

Vladimir Terekhov, CEO of Attract Group, said free ERP is a limited adaptation of the paid system.

Free software may not cost anything to use, but it often comes with limitations or may be a stripped-down version of a paid product. Open-source software, while sometimes free, is more about the accessibility of the source code.”

Mark McShane, managing director of AED, said free ERP solutions aren’t always free.

While free ERPs may waive initial fees, they often mask hidden costs for support, maintenance and extra features. Conversely, open-source ERPs signify more than mere exemption from license charges. Understanding the freedom to inspect, modify and enhance software is essential for businesses as they make their decisions.”

Pros and Cons

Open-source ERP – a publicly available, mostly- cheap and customizable software – sounds like a dream. While it certainly does have many advantages, it comes with downsides, too.

Miller discussed opensource ERP’s cost-effectiveness and risk.

Open-source ERP’s cost-effectiveness springs from its versatility. A business can often avoid expensive add-ons or modifications by simply tweaking the open-source code as per their requirements. However, this does introduce potential risks. Instances of faulty code or security gaps, for example. Therefore, security and regular maintenance should be high on your agenda.”

Terekhov explained that an open-source ERP’s public-access code garners risks and benefits.

Without a centralized authority overseeing the code, vulnerabilities may go unnoticed. However, with a vigilant community and proper security practices, these risks can be mitigated.”

Let’s dive deeper into the pros and cons of open-source ERP software.

Pros

Free Source Code

Open-source ERP can cost some, but the open-source code is typically cost-effective.

For those who don’t want to manage their system, you can find a vendor that offers a software-as-a-service (SaaS) solution. Typically, these systems have monthly billing and pricing, but it depends on what services you select and how many users you have.

McShane described how competitive an ERP open-source system market can get.

Companies can bypass steep license fees and redirect finances toward customization and process optimization. Moreover, the model fosters a competitive market for support and services.”

Highly Scalable

When gathering your ERP software requirements, it’s essential to consider what your business will look like in the future. Adding features or users down the road requires expensive re-implementations.

However, with the scalability of an open-source system, a growing business has the flexibility to make changes to its ERP system as needed.

Authority Over Customization

Direct access to source code allows users to be the sole authority over their system customizations. With this control, users can reach a whole new level of personalization.

Access to Community Support

Vibrant user communities support many open-source platforms – the support is experimental and transparent. For IT professionals who love immersing themselves in this environment, open-source can be a good solution.

These communities are known to quickly tackle system bugs, share their pre-built customizations or modules and more.

Independence From Vendors

From infinite flexibility to endless opportunities for innovation, independence from vendors can open many doors for software users. Think about it: open-source software users can always conduct business on their terms and schedules.

Cons

Requires Knowledgeable IT Team

With an open-source ERP implementation, you become the software professional on the project.

This responsibility is a significant roadblock, and it can automatically deter companies without access to a tech-savvy team of people from giving these systems a shot.

Overly Complex

All ERP implementation projects are complicated, but open-source implementations take the cake for complexity. Free-reign on customizations can get out of hand and become counterproductive if you don’t have a set plan in place.

Potential for Increased Risk

Highly established and financially stable open-source software vendors aren’t widely available on the market today. Some may consider it a business risk to work with companies that are still in their infancy.

Lack of Proprietary Engineering

One of the things that companies pay for with proprietary products is specific software engineering that serves their goals.

For example, all of the research and development that a proprietary vendor has done on their products can support less downtime, reduce different kinds of failure rates and increase ease of use, which supports the you-get-what-you-pay-for notion.

Independence From Vendors

Let’s revisit this one – while independence from vendors can serve as a perk, it comes with great responsibility. Open-source ERP users can only rely on themselves and their user community for support.

Less-Qualified/Knowledgeable Support

Proprietary ERP vendors and companies typically have a well-versed support team to rectify issues if any arise. Open-source software relies more on community forums and your IT staff to fix problems or bugs.

These forums can be a disadvantage because if you receive complex bugs, malware, spyware or viruses that are hard for your IT personnel to fix, how will you resolve the issue?

If someone in the support forum hasn’t faced this problem or doesn’t know how to rectify it, how will you reach a resolution?

Miller described that some open-source ERP support teams don’t fully know their terrain like those on a regular ERP system.

One can argue [this instance as] a case of depth versus breadth. [Open source ERP support] is less about having a structured support team and more about having access to a vast, diverse community of users and developers.”

McShane said open-source ERP system’s diverse community support can offer a wealth of knowledge, but often leads to “erratic customer service experiences.”

Pricing Considerations

While debating between regular and open-source ERP software, consider these pricing factors before you begin your search.

What’s the ideal deployment option?

Are you interested in cloud, on-premise or a combination of both? Picking the deployment choice that best accentuates your company is critical to choosing the ideal solution.

Cloud programs enable you to host the software and data on a third-party vendor while giving you real-time access on mobile devices. Review bank statements during lunch breaks or check invoice statuses before your next stakeholder meeting.

Conversely, on-premise strictly holds your software and data on your company servers, typically in one location, depending on your license. This option is usually ideal for small businesses.

Hybrid merges cloud and on-premise qualities into one option.

What are the company’s most requested requirements?

Develop a thorough list of requirements for your software.

Gather all of your department leaders for accounting, HR, marketing automation (MA) and more in one setting and poll them on what they need. Then rate how your ideal vendors’ solutions perform these requirements based on their data and demos.

How big is the company?

Are you a small business looking to expand into a Fortune 500 within the next five to 10 years? Are you an enterprise with national and global partners, stakeholders and clients? Are you looking to downsize in the next few years?

These and other questions are something to think over regarding company size. Some solutions can scale with your company as you add more employees, sectors, facilities and more. When choosing software, size does matter.

A new system or add-ons?

If your current system doesn’t work because it’s outdated and slow, it’s best to invest in a new program. It’s common sense. However, if you like your current system, you can purchase integrations and add-ons, saving you money.

For example, you have an ideal accounting platform, but you need to manage manufacturing, enterprise reporting and professional services automation (PSA). You can purchase separate solutions or get add-ons that integrate with your current platform.
