ERP is an abbreviation for “Enterprise resource planning”. ERP systems are used in small, medium and large businesses to do the work that the company needs from day to day. You can think of it as the software responsible for managing the companies activities.

How should you choose your ERP?

As usual, there are proprietary closed-source ERP systems that cost a lot, and there are open source ERP systems that can be used alternatively. Which one to use depends on your own scenario; You organization’s size, number of staff, the type of modules and features you need and other similar criteria.

Almost all the solutions that we are going to see offer two versions: A managed SaaS (software as a service) service that you pay for each month according to the services and the number of users you have in your organization, or a self-hosted open source version that you can download for free with no support.

Apparently, the first step should be trying that ERP system that you like on your local machines, testing whether it’s sufficient for your tasks and employees, and if so, you could either purchase it as a SaaS, or request professional support when needed with the open source, free version.

But why would you choose one software over the other? The reasons are many: The offered functionality of that ERP system, the user interface design, the programming language of the system, is your IT department capable of modifying and developing that open source ERP system even further, localization, GDPR compatibility.. And many similar criteria.

Today, we would like to present 7 open source ERP systems that you can depend on.

Odoo offers tons of apps; CRP, accounting, invoices, website builder, eCommerce, email marketing, project management, inventory and many more other apps. Such wide set of possible applications make is suitable for almost any type of business you may have. Additionally, the UI design of the system is very modern to today’s standards.

Odoo also supports 3rd-party apps, which are apps that are developed by the community for the Odoo system.

Odoo Studio allows you to build your own Odoo app and distribute it, if you want.

If you are from EU, then you would be happy to know that Odoo is compatible with the new GDPR law.

This ERP system is more classic. The UI isn’t really suitable enough for 2019, but still it provides many functionalities that you may find useful. Dolibarr is written in PHP and released under GPL 3. Its development started back in 2002.

Just like the others, Dolibarr provides modules to manage CRM, sales, finances, human resources, electronic documents, projects, calendars.. And many similar tasks.

Tryton

Using “modularity, scalability and security” as its slogan, Tryton is a very unique ERP system comparing to the other options. Its architecture uses a three-tier model to maximize the modularity of the software, making it closer to being a framework that can be developed later for any further requirements. Tryton system consists of 3 parts:

  1. Tryton Database: Data storage system such as PostgreSQL.
  2. Tryton Server: Main application responsible for providing the Tryton functionalities.
  3. Tryton Client: A desktop/web software to communicate with the server.

What’s unique is that Tryton is mainly using a desktop client for its operations, making it working natively on various Linux distributions (You can even find it in the official repositories). All the system is written using Python, and uses GTK library for its desktop client. There’s also a web client if you need.

Tryton provides modules to manage CRM, accounting, sales, inventory.. But also provides modules for supply chains, manufacturing and shipping, making it suitable for factories or shops.

Tryton also provides a free demo, docker images, prebuilt binaries for Windows, Linux and macOS. It is also available as a Python package to be installed using pip. Many 3rd-party modules can be installed for the system using pip as well.

Describing itself as the “most powerful open source ERP system”, ERP5 includes a huge set of modules that makes it suitable for almost any type of buisness. Those modules include banking, accounting, CRM, HRM, projects, eCommerce, PDM, KM, forums, consulting, barcode, email marketing, invoicing and manufacturing management modules.

ERP5 is indeed very popular in all parts of the world, you may find your ordinary retail shops or country’s official banks using ERP5 somewhere on their ecosystem.

One downside, however, is that the user interface of the system is very old and classic. It’s not modern like the other ERP solutions mentioned here.

Flectra

7 Open Source ERP Systems That are Actually Good 29 open source erp

Flectra is another ERP system that was released just few years ago. Flectra is actually fork of Odoo, however, Flectra was created for seemingly two main reasons: First, to allow a more open, collaborative development of the source code, and also offer much better pricing for the SaaS subscriptions provided by Odoo, and secondly to provide more features that are needed by the community.

Odoo initially didn’t like that move, as it saw Flectra as one of its possible competitors but using their own open source code, so they started a lawsuit. A lawsuit which would continue for almost a year before a jury in India announces that there are no copyright infringements in Flectra and that it’s OK to proceed working.

Thus, Flectra provides the same modules that Odoo provides, but with much better pricing and a noticeably newer user interface. There are also many new features that are supported by Flectra that are not supported by Odoo.

    I would also recommend Idempiere ERP (www.idempiere.org). It’s a fork of Adempiere ERP (www.adempiere.net), but adds OSGI framework and thus the ability to create functional vertical plugins which are isolated from the core ERP.

      Peoplesoft is not Open Source so doesn’t belong on a list of Open Source ERP systems.

      If your business is growing, surely tally will not be able to handle your business needs. This is a critical stage where you need a process to be in place and have a clear visibility of stock and inventory along a handy mobile app and with a technology which can help you for atleast next 2 decades.
      You should now go for ERP.

      As I feel naming something as ERP doesn’t actually means it’s an an ERP. Accounting software companies are playing with the users mind by using ERP with there product name.
      ERP comes with controls, process driven scenario and lot many features.
      Why dont you check out EPPS Gro, it’s avery good ERP which caters to client who are in growing stage and citywide also it’s cheap giving you a real process driven environment and once you are acquainted with process you can move to the higher version Of EPPS ERP i. e. PRO..
      Remember one thing small steps leads to success.

    And what about the IDempiere Business Suite? Odoo comes out of the box with very simple options. If you are coming from QuickBooks, and you need a simple ERP system help you manage your business, Odoo will look and feel comfortable.

    But iDempiere comes out of the box with every feature installed and configured to run a $200M+ USD business. If your business is growing rapidly, and you are willing to invest the time to learn an enterprise accounting system, then iD/AD will give you confidence.
