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 change, customize and distribute it as they like.
This open approach promotes teamwork and clarity and allows the system to tailor exactly to the custom needs of a company.
The advantages of Open Source ERP
The decision for a Open Source ERP brings a number of benefits that make it a superior option for many companies.
Flexibility and adaptability
The biggest advantage of open source ERP systems is its enormous room to adapt.
Since the source code is open, companies can adapt the system to their specific business processes to the smallest detail.
Whether it comes to integrating extra modules, changing workflows or developing completely new functionalities, the options are virtually unlimited.
This creates a tailor-made solution that adapts to the company and not vice versa.

With an open source ERP system, companies do not depend on a single provider. They are not linked to their product cycles, price policy or support offers.

Here companies can either rely on their own developers
