Capterra’s blogs aim to be useful to small business software buyers. Capterra participates in vendor affiliate, referral, and pay-per-click programs where available. This means after a content piece is written by our researchers, our affiliate manager converts existing mentions of vendors into affiliate links where possible and adds PPC links where appropriate. When readers click on those links, sometimes we make a small commission and when they make purchases, sometimes we earn an affiliate fee. That said, we do not accept free products or services from vendors in exchange for mentioning them on the site.

No Capterra blogs or blog posts are sponsored by vendors; further, our writers independently choose which vendors to cover and what to write about them. In fact, most of our writers are unaware of Capterra’s affiliate relationships.

Update 7/20/2017: We’ve added some new ERP options and removed those that were out of date.

Solving complicated problems for your business doesn’t mean you have to splash out on a million dollar enterprise resource planning (ERP) system. Oracle and SAP may dominate the field, but there are plenty of free, open source ERP options that can help get your business in shape.

top free and open source erp software

Before we dive in, a word to the wise: putting an ERP in place is a headache. Most implementations go over budget, take too long, don’t deliver on the plan, and just generally make businesses miserable.

Don’t fall into those camps. Having a clear plan, a clear problem, and clear goals is the recipe for ERP success. Even a “free” ERP costs your business time and money.

The following options are presented in alphabetical order.

1. Dolibarr ERP

Dolibarr ERP is super popular, and I feel genuinely remiss for not having added it to this lineup earlier. So far this year, it’s already been downloaded 129,000 times from SourceForge, putting it light-years ahead of my Linux-based keno simulator, “Keno Speaker.”

Dolibarr in action (Source:

Dolibarr comes with everything an ERP needs, including accounting, CRM, HR, and inventory modules. If you want to expand functionality into the weird or incredibly specialized, Dolibarr offers apps through its Dolistore—you can also just build your own, if you’re so inclined.

Due to its popularity, Dolibarr is updated pretty constantly and has a very active user forum for troubleshooting and general discussion. On that note, it’s also a very popular program internationally, meaning Dolibarr is likely to be available in your language—assuming you speak a European language, that is.

Dolibarr is a great option for businesses with in-house tech teams and those that want to be a part of a bigger ERP community.

Cloud installations are possible, though you might be better off outsourcing to one of Dolibarr’s hosting partners. You can read reviews of Dolibarr on the project’s Capterra listing.

2. ERPNext

ERPNext is an open source solution with the modern user in mind. ERPNext is designed for small and medium businesses (SMBs) and is presented as a series of apps. The whole system is designed for the less technical among us, which is both a blessing and a curse.

ERPNext’s simplicity means that it’s easy to set up, using simple forms to enter information about your business and walking you through the whole process in typical setup wizard style. It’s a feeling that quickly becomes familiar, as the ERP is clean and user friendly.

Of course the downside is in expanding the ERP to fit specific needs for larger or more complex businesses. While there are built in tools for designing specific forms and reports, adding more complex elements requires diving head-first into the code.

ERPNext is free for five users when hosted online, or free for any size business when installed on your own servers.

3. iDempiere

iDempiere is a full-fledged ERP, with everything from invoicing to POS integration to warehouse management to forecasting. While iDempiere is open source, installing an ERP is never truly free. Chuck Boecking, an ERP specialist, suggests budgeting between $20 ,000and $100,000 for businesses earning $10 million to $100 million.

iDempiere, like most open source programs, relies on community support for troubleshooting. Businesses may also call in specialists with experience in iDempiere.

The software provides just about everything an ERP could, including product planning, warehouse management, and payroll, among many others.

While it requires more setup than some of the other options on this list, iDempiere is one of the most robust open source options available.

4. MixERP

MixERP is free and open source, built on the framework. In its free iteration, you manage hosting and upgrading, but you’ll have access to support for $49 per issue. It’s a nice mix between do-it-yourself and complete outsourcing.

The free version comes with all the bells and whistles, including inventory management, sales management, accounting, and HR tools to keep your business running smoothly. It does lack manufacturing and payroll management options, though, so larger companies will need to use one of the cloud or on-premises, paid versions.

5. Odoo

Odoo offers one application for free for unlimited users when hosted online, and adding additional apps will typically run you from $12/month-$72/month depending on the app. However, if you install and maintain the software in house, Odoo is totally free.

Odoo’s distinction is that the whole system revolves around a collection of apps. The software has apps to cover everything from warehousing, manufacturing, and sales channels, to timesheets, websites, and purchasing.

You can bolt on access to apps for a monthly fee that help you build a website, install eCommerce portals, run a CRM, and on and on. The benefit of this system is you don’t end up running a bloated system when you could be running a slim setup.

Odoo’s obvious downside is the limitation on the number of free apps or, as with other open source software, the need to have enough in-house technical expertise to set it up and run it yourself. Luckily, adding more apps isn’t prohibitively expensive. With its scaled approach to users and features, Odoo provides a solution that can grow with your business.

6. Openbravo

Openbravo is a retail-focused ERP based on a modular system. The software comes in three “flavors” depending on the needs of your organization. Openbravo Community edition is the free release, offering a stripped down version of the paid Enterprise and Professional editions. These editions include some premium, commercial modules — like financial management and inventory management — that many businesses find necessary.

Moving up to the Professional or Enterprise editions will set you back, so talk to Openbravo for a quote before you make a final decision.

Like Odoo, Openbravo’s open source meets commercialized product approach gives users a place to go for support besides just community forums. Of course, support comes at a cost, which can put a damper on the lower cost option that open source often offers.

7. VIENNA Advantage Community Edition

VIENNA Advantage is an open source ERP out of Germany. The core product includes an ERP and CRM that the rest of the solutions revolve around. The platform is web-based, so you can access it across devices and without having to worry about some of the nitpicky compatibility issues that plague small businesses.

The Community eEdition is a free option for “developers, technical companies and microenterprises looking to deploy a basic set of features.”

There is no built-in support for this edition and you’ll have to have someone with strong technical skills on-hand to get things running smoothly.

That said, once installed, you’ll have access to a ton of free modules. These include document management, accounting, and reporting tools.

If you end up loving the product and want to move management over to someone else, Vienna offers two cloud-based, hosted solutions. One for SMBs and one for enterprise clients.

8. xTuple PostBooks

xTuple makes a range of ERP and manufacturing-focused products, but the core of all these options is PostBooks. PostBooks manages the central functionality of an ERP, which is extended by xTuple’s other offerings.

With PostBooks, four users get access to almost everything you need to run a single-location operation. That means inventory for one location, accounting, billing, reporting, and other sales tools. You won’t get multiple locations, advanced MRP tools, or other advanced planning tools, but you could extend into those features later with one of the paid offerings.

PostBooks is a great fit for service companies, as they don’t have the advanced manufacturing and inventory requirements that would require an upgrade. Even for a smaller, single location warehouse, PostBooks could be a good fit. Just know that you’re limited in your scale if you’re planning to stick with the free option.


The range of open source ERP options should offer a solution for almost any business. While implementations can go awry, making clear plans and having an understanding of the problems that you’re trying to solve with an ERP can take a lot of the sting out of putting one into place.

Thanks for this great resource – we have found there are certainly some interesting solutions out there that are free the problem comes when you need support or any changes done – its difficult to get and honestly no large business will commit to an ERP or any kind of purchasing software system where the support is questionable.

@Andrew, thanks for listing ERPNext. A simple interface can be curse to the product too. ERPNext comes with more out of the box features (like Serialized Inventory) than many of the others listed, but may appear simpler.

@James, on the contrary, for open source products, its much easier to get changes implemented. Most open source products are backed by solid commercial enterprises and there is an army of freelancers that are available based on your budget. Its just a matter of time the perception aligns with reality.

@james In my opinion, Open source business model is the future business model in software. I think it embraces community support and continuous innovation. You maybe surprised by the quality of support open source businesses provide.
P.S. checkout

Hi Andrew, thanks a lot for adding us to the list. Let me add however some comments that I think will help to better understand our offering today.

The screenshot you are sharing belongs to our old version. Since we launched Openbravo 3, we have a much more stylish and productive user interface (

In the past our flagship product was Openbravo ERP. It has evolved to 2 different products. The Openbravo Business Suite (, a global management solution with horizontal ERP, CRM and BI functionality for across industries, and the Openbravo Commerce Suite ( for retailers. So if we talk today about our general ERP solution, we would talk about the Openbravo Business Suite. In fact the prices you are mentioning correspond to the Business Suite.

Do not hesitate to ask about any question you may have and again thanks a lot for mentioning us.

Best regards,

You may also mention Dolibarr Erp Crm ( designed for small and medium businesses.

Can u help me something that i can use for Pharmacy retail..

See also OpenZ ERP. I think its one of the best open source erp system. A great system, with a huge community and a fair pricing model.

Another alternative that is free…completely free…is BlueSeer….available at It is a Universal ERP for manufacturing that has a lot of punch in core manufacturing (MRP, Job Scheduling, Order tracking, Ledger, AP/AR, Timeclock, and EDI). It’s aim is to be a generic community ERP.

Never have heared about Odoo, nevertheless a really great summary 🙂

Hi Andrew,
I strongly think that VIENNA Advantage ERP & CRM should be added to this list. It is the first ever open source ERP & CRM solution with inbuilt Document Management System available on the cloud or on premises.

It was recognized as one of the “20 most promising Open Source ERP solutions in the world by The ERP Insights Magazine >

We have a selection of products which work well both in a cloud and on-site. Before choosing the right option for your business, a few factors are worth considering as both solutions have their pros and cons. Personally, I would be into a cloud-based erp as locally based software usually entails bigger investments

Thanks Andrew for sharing such wonderful list of ERP Software. Keep it up your efforts.

I’m looking for an ERP that has great UI and can do all functions / modules like sales, purchase, inventory, manufacturing, servicing, CRM, taxation, etc

perhaps our Scipio ERP also matches your criteria. The Community Edition is licensed under the ASF 2.0 and is quite modern.


Grate post Andrew!
I’m looking for some useful ERP too! Like Laurent, I think Dolibarr should be added to this list, is really used here, in Europe!
Searching on the web, I’ve found this page: it explains the differences between the biggest ERP, there are no free, but anyway it can be useful for the new business-men!
Thanks by the post!

Hi Andrew,

We offer All types of third party integration and customization service in odoo at reasonable price


Odoo indeed carries a lot of benefits with itself. All the features mentioned make it worth using by the businesses which seek growth and development opportunities. I was also looking for odoo services for my business and I was referred to by a consultant and I was not disappointed at all. They delivered exactly what they promised and what I expected.

Very useful open source ERP list. ERP’s are always interesting and useful for a company to use. Hope our company could contribute to the open source system as well.

We used Odoo since two years for all our consulting operation. Also we provide services on Odoo. We have around 9 years of experience in Odoo.

Odoo is great software to manage your business with great user friendly interface.

A question: why did you mentioned iDempiere (even in first place) and not aDempiere which has more history and more business functions?

thanks for sharing such a informative Blog. Web based ERP Software makes the environment of the school much more user-friendly.

Great post Matt! Seen recently good newcomer, which pretty much meets up all of described features, called EasyERP. And, of course, it`s open source, so it`s quite customizable (as those guys from support say), but it doesn`t lack in any necessary, for good CRM, features. Plus it is also a complete ERP system too. Found it at Hope you`ll find it useful too, and probably will include it in a new list =).

Hi Andrew,

Nice article!
But do you think choosing the best Open Source ERP is such an easy job as there is nothing known as the “best” in the Open Source ERP. The reason being, as most of the ERP companies provide just a skeletal structure of an ERP but not a complete plug and play solution specific to your business irrespective of their pricing or brand equity.

This is a classic case of chicken or egg story. Does the consultant come first or the ERP platform? To our knowledge, it’s always the consultant first. What is important is to choose the right consultant who is willing to work with you closely, understand your business, it’s dynamics like the size of the business & it’s scalability, come up with a vision plan for deploying the ERP & implement it with elan. Because 5 out of the 10 ERP implementations across the industries are a flop owing to different reasons. Majority of them are purely because of the lack of knowledge about the ERP, it’s functionalities, dependencies & of-course it’s fit for your business.

What is important is, the consultant should be a perfect cog in the wheel connecting your business & the features and functionalities of the ERP.

Do you agree?

We have deployed ERPs based on Openbravo ERP mentioned here with 100% success rates. Many of our clients are leaders in their respective industries. One of our ERP solution for Apparel & Footwear retail chain (Details can be found here )was a huge success. Though this may sound like a sales pitch, The fact is the ERP becomes best when there is somebody who can come up with the best solution specific to your business. We are one of the very few who belong to that tribe.
