An open source ERP system is a company software whose source code is publicly accessible. This means that companies can not only use the software for free.

However, also adapt it to their specific needs and develop it. This room to adapt is one of the biggest benefits of open source solutions.

Unlike closed systems where one is bound to a provider, open source software has full control.

As with any technology, there are also benefits and disadvantages for open source ERP systems that companies should carefully weigh down.

Benefits:

• Independence: There is no dependency on a single provider (Vendor-Lock-in).
• Community support: An active developer community often offers fast and free support via forums and other channels.

Additions:

• Rollout effort: The adaptation and rollout of an open source ERP system can be complex and requires internal IT know-how or the assignment of external service providers.
• Hidden costs: Even if the software is free, costs for adjustments, training, maintenance and support can be incurred.
• Maintenance and updates: Unlike commercial providers, you are responsible for installing updates and maintaining the system itself.
• Insurance: There is no guarantee for troubleshooting, as the community is not obliged to do so.
