On this page, we have collected the top ten feature-rich and flexible open source ERP systems. The top guns in this department are Microsoft, SAP, and Oracle. But, their products are expensive. What if the organization cannot afford ERP software developed by these brands? You look at open source solutions.

Businesses with a lot of employees have a wide range of tasks to tackle, including inventory, payroll, finance, accounting, and planning. None of the developers can create separate tools for all the tasks and then stitch them together to perform simultaneously. It’s where you can turn toward enterprise resource planning (ERP) systems.

How to find the best open source ERP system for your business?

  • Consider business growth: You should look for an ERP application according to your needs. So, taking all the components of an ERP might not be a bright idea. However, you should consider future growth and find something that can adapt as per the expansion. Therefore, you can try ERP software with additional modules or plugins available to install when you need to add new functions.
  • Hosting: The open-source ERP systems are available for cloud-based services and on premise installation. Download and install such software only if you have a trained staff to maintain it. Otherwise, go for the cloud version.
  • Support: Ensure the ERP software has complete documentation and support. A user community and knowledge base are helpful. But, a support chat, e, mail or phone number could be better.
