In today's digitalized business world, an efficient enterprise resource planning (ERP) system is crucial for the success of a company.
It integrates and automates central business processes such as finance, human resources, manufacturing and supply chain management.
While traditional proprietary ERP solutions dominated the market, open source ERP systems are becoming increasingly important.
But what exactly is behind the term Open Source ERP and what opportunities and risks are associated with it?
In this article, we highlight the advantages and disadvantages of open source ERP systems to provide you with a sound basis of decision.
What are open source ERP systems?
Short: Open source ERP systems are enterprise software solutions whose source code is publicly accessible.

They are not bound to the product and price policy of a manufacturer and can freely choose the service provider for support and maintenance.
This creates a greater negotiating power and long-term security.
4. Transparency and security
The open source code allows developers and security experts to check the code for vulnerabilities. This often leads to higher safety, as errors and
