Here is our curated list of open-source ERP software to manage your business like a pro.

Running a family of four, I often see resources lying unused and wasting their life cycles. You can tolerate that at your home, but doing that with your business is never a good thing.

Most organizations combine micro-level disparate systems needing an alignment. That's precisely where Enterprise Resource Planning (ERP) comes into the picture.

Now you can either self-host or go for cloud management. Self-hosting is more secure and generally an economical option. You can host software on your favorite cloud platform and have full control over customization, security, etc. But Cloud can be easy to back up and is aimed at non-tech savvy business owners.

So, let's start with the list and see what's there in the offer with these self-hosted Open-Source ERP Software.

Odoo

Odoo provides a suite of applications to manage every aspect of your business. These individual applications are integrated and can be purchased separately.

Applications include:

  • Blog, eCommerce, and eLearning platforms builders. Create forums & live chats to directly talk to your customers.
  • CRM, quotation, and Point of Sale applications. Rental and subscription management.
  • Finance Apps for accounting, invoicing, expenses, eSignatures, etc.
  • Inventory and Manufacturing applications for product life-cycle, purchase, maintenance, quality management, etc.
  • Manage recruitments, time-offs, appraisals, fleet management, etc.
  • Marketing automation utilities like email marketing, SMS marketing, event, and survey management.
  • Optimize projects, field services & customer service, appointments, and meetings.
  • Team communication utility, VoIP, and IoT management.
  • Odoo Studio to build mobile applications.

Odoo ERP comes in two formats: community and enterprise editions. The community version is free and open-source with limited features.

The best way is to start with the community edition and upgrade if need be. Notably, cloud hosting is free and costs the same as self-hosting subscriptions. However, extra costs do apply for allowing custom modules.

Alternatively, you can get Odoo hosting on Kamatera with one click.

Conclusion

The real cost of implementing an ERP lies with the hosting and support. This is a tough lesson my previous employer learned the hard way and switched back. He was lucky as the organization was small, and there wasn't any vendor lock-in.

So, ensure a fluid roll-back policy before transitioning to any ERP software.

And while the free option seems tempting, implementation support and cloud hosting has proved a life savior in most cases.

Generally, an ERP software with separate individual applications is the best one to start with. Conclusively, go slow and be informed.
