How We Chose the Best Open Source ERP Software

Enterprise resource planning (ERP) software allows businesses to streamline their accounting, planning, and scheduling procedures. While it’s possible to have multiple applications that facilitate these processes, it’s not advisable. Ideally, you want a singular platform to manage the various aspects of resource planning effectively.

We find that the key features to look for are integration possibilities and user-friendliness. Through third-party apps, professionals from any industry can make use of the software. Although you can find paid versions of different ERP platforms, there are many free options available.

That said, spending a bit more on the right software can save you valuable time and money down the road. While it may be more appealing to go for a free program, paid versions are more likely to have reliable support and access to advanced features.

Some of these platforms have a community, while others depend on the developers’ direct assistance. To save you the trouble of scouring the internet, we’ve sourced 15 top ERP programs.

We have particular criteria when it comes to labeling something as the best open source ERP software. The following aspects were all taken into consideration during our evaluations.

ERP Features

There may be similarities between the different ERP programs. When deciding on what will work for you, look at your needs. Contrary to popular belief, more features aren’t always a good thing.

Some platforms allow an incredible amount of customization ability at the cost of developer-level knowledge. Being stuck attempting to apply a plug-in during an event like Black Friday can cost your business dearly.

When selecting the best open source ERP software, our advice is to focus on what you need. Test different platforms and look for scalability options. What might seem trivial today could be of vital importance next week.

When selecting the right programs, consider the following:

  • Scalability
  • Hosting options
  • Fraud detection
  • Support capabilities
  • Integrations

Regardless of the software, you decide to use, make sure it has the proper documentation and working support. Whether it’s community-based or customer service, look for one that offers efficient assistance. The last thing you need is to wait for help while your CRM is down.


When sifting through your options, it’s essential to assess the integration possibilities. The best open source ERP software provides unified functionality for a variety of external tools. Although we mainly look at programs with versatility, some are so well-designed for a specific purpose that we have to include them.

Keep the following integration options in mind:

  • Accounting systems
  • E-commerce
  • Warehouse management
  • Expansion options


When generating reports, information needs to be accurate and up to date. The best open source ERP software offer statistics, metrics, and inventory tracking.  These tools help you monitor operations and evaluate performance. They also provide insightful data you can use to streamline your business activities.

While it may seem arbitrary, a user-friendly interface also makes things a lot easier. The ability to customize your UI can save valuable time and money down the line.

Look for features that include:

  • Warehouse and inventory tracking
  • Performance statistics and metrics
  • Accurate reports
  • User-friendly CRM

The 15 Best Open Source ERP Software of 2021

We evaluated numerous programs to bring you 15 of the best open source ERP software available. In the spirit of objectivity, we listed them alphabetically and not by favoritism or cost. While we have our perspectives about all of them, we aim for complete detachment.

In the table below, you’ll find vital information such as pricing, free trial/demo options, and links to each respective provider. After that, you’ll find objective reviews of each software solution so that you can make an informed decision.

Apache OFBiz

Apache OFBiz
Apache OFBiz is an extremely user-friendly application. It comes with product and pricing management, supply chain fulfillment functions, and add-on modules. Because it’s a stand-alone application, you’ll need to download and install it on your system.

Pros & Cons of Apache OFBiz Open Source ERP Software

You can download the Apache OFBiz application from the provider’s website. As free software, anyone can give it a try, regardless of industry or technical experience. While this open-source software has an active community, it’s smaller than others. If you’re looking for help, it could take some time for someone to come to your aid.

ApacheOFBiz also lacks a performance metrics function, so you’ll need to find an alternative solution. All things considered, though, it still packs a punch with its range of features.

>Fully customizable
>Scalable to fit your business
>Free and open source
>Doesn't offer performance metrics

What Customers Are Saying

Users praise Apache OFBiz as one of the best open source ERP software because it’s “helpful for all kinds of people.” Having “easily understandable features” allows customers to make quick changes without the need for assistance. However, some have said that it can become “challenging for a developer to keep track of technologies.”

Pros & Cons of Compiere Open Source ERP Software

The Enterprise Edition of Compiere is one of the more affordable ERP software on the market. Because you have to pay, it helps that you get a 30-day tailor-made trial demo when you request a quote. However, the fact that the customer support team is only available by phone during business hours means you may have to wait for assistance. There’s also a noticeable lack of supply chain and HR management features, which isn’t a problem if it’s not something you require. Still, it offers sales lead tracking and multiple currency support.

>Sales lead tracking
>Multiple currencies

What Customers Are Saying

Pros & Cons of Dolibarr Open Source ERP Software

Dolibarr has many fantastic features that let you expand with growth. However, one of the things it doesn’t have is social media integration on the CRM. On the upside, it offers task and warehouse management as well as email and marketing automation functions.

ERP5 is an enterprise system with various core and business templates. Because it’s generic and customizable, you can adapt it to meet specific business needs.

It has financial management features and industry templates and supports numerous plug-ins. The idea behind ERP5 is to model the system according to the needs of any industry or business.

Pros & Cons of ERP5 Open Source ERP Software

The beauty of ERP5 is that it’s accessible on multiple platforms, with the option of carrying data over. You can contribute to the software development if you’d like, but the developers ask that only advanced users do so.

The extensive manufacturing and inventory management applications are user-friendly and easy for anyone to learn. On the downside, there’s no warehouse management integration. Moreover, you’ll need to log a request and get a ticket before reaching customer support. For free software, that’s not too bad, though.

>Free and open-source
>Large application library
>No warehouse management
>Support is only reachable through ticketing

What Customers Are Saying

ERP5 has mostly positive reviews. The majority enjoy that it’s “highly configurable” and has a “high level of flexibility.” Customers say that it “could power websites and provide integration of front and back-office in a single system.”

Pros & Cons of ERPNext Open Source ERP Software

ERPNext also comes with a range of reporting and tracking tools for employee attendance, assets, payroll, tasks, and leads. There are also timesheets and a real-time cash flow feature. While it may have everything you need, it’s still reasonably young. That means there are frequent updates and improvements.

Still, ERPNext is at the top of the list for many companies due to its versatility. However, advanced knowledge may be required for some customizations, and customer support can take a while.

>Asset, attendance, and payroll reports
>Real-time cash flow view
>Timesheet, task, and lead tracking
>Support can be slow to respond
>Heavy coding knowledge required for more advanced customizations

What Customers Are Saying

Customers say that the best part about ERPNext is that it’s “truly fully open source.” Clients praise its customization possibilities, stating “the flexibility of ERPNext is unrivaled.” As we mentioned in the cons list, some users find it overly complex and claim that “upgrades are a bit difficult for someone non-technical.”

Pros & Cons of Flectra Open Source ERP Software

Flectra offers next-level assistance to its customers. With 24/7 online availability and priority support for businesses, you can resolve any issue before it becomes a problem.

Because there’s only a paid version of the program, the 10-day demo comes in handy. You’ll be able to take Flectra for a test run and try out its features. However, you won’t find project scheduling or order management among them.

Pros & Cons of iDempiere Open Source ERP Software

iDempiere is a versatile software that’s compatible with almost any device. Its main features include resource planning and customizable CRM, but it lacks HR, warehouse, and financial tools.

There are free servers available for testing, and you can even download the program to host a local one. Remember, most of the support is from the online community, so fixing problems takes time.

>Fully customizable CRM

What Customers Are Saying

There has been lots of positive feedback about iDempiere. Because it’s a free platform, you “have access to all the functionalities developed within [the] community.” Customers are “really amazed” that you “can customize [it] without changing [the] core in hardcode.” Other users conclude that it’s a “serious enterprise software suitable for medium businesses.”


Metasfresh is an open source ERP software used in industries like food, wholesale, trade, and service. Because of its flexibility and adaptability, it’s perfect for SMEs as well as start-ups.

Pros & Cons of Metasfresh Open Source ERP Software

Metasfresh is fantastic if you’re looking for a free platform with comprehensive reporting and tracking functions. However, it doesn’t offer HR management. That said, the only difference between the hosted and non-hosted versions is the inclusion of support.

The paid option gives you access to a live rep 24/7. It’s not all bad news for free users, though, as the community has many FAQ sections and is always happy to help.

>Live rep support available 24/7

What Customers Are Saying

Users say Metasfresh is a “very flexible and widely configurable software.” We tend to agree with them. Even when using the free version, it’s “very nice and easy to work with.” However, some customers say there’s a “steep learning curve to do [your] own configuration.”

Pros & Cons of Odoo Open Source ERP Software

There are very few ERP solutions that offer the same level of functionality across multiple devices as Odoo. The price of premium support, however, can be a bit costly.

Fortunately, the Odoo free version has the same essential features and a massive community that’s at your beck and call. However, you may want to learn a bit of coding if you’re going to utilize the customization abilities to the fullest.

>Free community version

>Difficult to customize

What Customers Are Saying

There are mixed reviews for Odoo. Businesses say Odoo is “an extremely powerful software,” while others state that “customization is not easy.” Generally, users report that it’s “hard to learn and difficult to maintain without an IT department.” Fortunately, “the software has many functions out of the box.”

Pros & Cons of OpenEducat Open Source ERP Software

Ideal for schools and universities, OpenEduCat allows you to record attendance and achievements. Students can access information through the mobile app and update schedules. There are also over 300 modules and controlled examination tools.

The main focus for OpenEducat is towards education, which creates a limit to the functional capabilities. The lack of warehouse and inventory management is negligible, given the focus industry. As a premium product, there’s no free version, either.

Pros & Cons of Tryton Open Source ERP Software

We find it difficult to find fault with Tryton. There’s no specific pricing model, which can be confusing until you realize you have access to a wealth of community plug-ins. Support can also take time as there’s no direct contact number. Usually, the community can help you resolve issues, though.

With webERP, sales and purchase orders are seamless, while inventory management and tracking ensure complete oversight. Moreover, PDF reports make it easy to collate and share pertinent data. However, webERP lacks 24/7 customer support, so you’ll need to wait until business hours before receiving assistance.

xTuple PostBooks

xTuple PostBooks
xTuple PostBooks was a free-to-use, open-source ERP solution that was discontinued in 2019. While you can still find it on GitHub, it’s no longer officially supported by its creators, xTuple.

However, the company still uses the same software, albeit closed-source, with many subsequent improvements. If you’re not a developer particularly concerned about xTuple’s non-free, proprietary licensing, then it’s still an excellent platform worth considering.

It’s designed for manufacturers to grow their businesses using inventory management software. The system has various automated features that can save time on many back-office processes.

You can choose between an annual rental license and an owner license. There are four pricing options available, all of which include a 90-day trial.

When you buy the cloud version, you also gain access to the disaster recovery service, which has off-site data backups.

Features include:

  • Warehouse, distribution, and inventory management
  • Reporting and analytics
  • Supply chain management
  • CRM functionality
  • Operations management

What Is Open Source ERP Software?

Open source ERP software is an online or offline platform that helps your business manage inventory and customer relations. It can come with built-in features that grant increased functionality and adaptability. The critical focus of ERP software is integrating multiple third-party add-ons to provide increased workflow possibilities.

Multiple deployment options exist for ERP software. Although most of them are available on web-based, cloud, and SaaS systems, you can find a few mobile applications, too.

Most open-source software platforms have a large community of developers behind them. Regardless of whether you opt for free software or paid counterparts, you’ll find solutions to any problems you may encounter via specific forums. That said, it helps that most paid versions have 24/7 customer support.

ERP software collects activity information and tracks data to increase productivity. The right program avoids inefficient workflows and improves departmental collaboration. Through the integration of all your financial information, your company’s reporting is unified, too.

Benefits of Open Source ERP Software

Regardless of your company’s size, open-source ERP software offers numerous advantages. Apart from versatile third-party integrations, here are a few salient benefits:

  • Streamlined workflow: Employee reports, attendance registers, and schedules allow you to monitor workforce performance. Moreover, calendars and reminders ensure collective and simultaneous disclosures.
  • Optimized inventory management: Manufacturers can meet customer needs while managing essential resources through real-time data. With tracking, inventory updates, and warehouse management, you’ll have a semi-automated enterprise. These features enhance performance, giving you more time for other business activities.
  • Reduced costs: With ERP software, you can replace a series of functions and programs across various departments. Not only does it aid in improving workflow but it also cuts costs.
  • Collaboration: Through communication tools, you can facilitate interactions and employee participation. A stable and user-friendly CRM will allow you to keep track of customer needs, ensuring you’re able to meet them.
  • Usability: Most ERP software is available as web-based programs. Plus, they’re often compatible across multiple devices and platforms, with the same customization and functionality.

Must-Have Features of Open Source ERP Software

When looking for the best open-source ERP software, keep an eye out for these essential features:

  • Customer relationship management or CRM: Without a CRM tool, you’re unable to keep track of customer needs. The more customization possibilities you have, the better your overall engagement will be.
  • Warehouse management: The optimal warehouse management system gives you full control over all process flows. You should have access to lot availability and capacity.
  • Integrations: The best open source ERP software should be fully integrable. Through multiple plug-ins and add-ons, your workspace should be fully customizable.
  • Financial management: A reliable financial management integration permits you to do all your accounting from a central database. By creating automated double entries and regular data backups, your ledgers will remain accurate and secure.
  • Inventory management: Modern ERP software allows organizations to improve customer service by providing real-time access to inventory information. By using a cloud-based ERP system, you can manage distribution processes without forgetting about costs.

The Cost of Open Source ERP Software

As you can see from the above, there are numerous options for each ERP platform. Many allow demo access to the software, while some ask for a small fee or a subscription for the hosting service. Because they’re open source, a few are entirely free to use.

Payment plans vary among different platforms. Some have an annual or monthly subscription, while others offer one-time purchases. We noticed that the range could be anywhere from $4 per month to $1,000+.

That said, some ERP software products require you to request a quote. Depending on your company size and needs, most provide you with a tailor-made program. Usually, they offer anywhere between seven-day and 90-day free trial versions. For custom ERP solutions, the price range varies between $300 and $4,000 monthly.
