Benefits of open source ERP

  • Reduces costs: If your organization is small, or a start-up you will be not in the position to consume more money for ERP software. In this case, open-source ERP is the best solution. For open source ERP software, you need not pay license charges to get source code. You can install, implement, and customized it freely. Many open-source ERP solutions have a wide range of features.
  • Easily customizable: If you have cloud ERP solutions or any paid solutions, you have to contact your vendors for customization. It takes more time to communicate with each other. But with an open-source ERP solution, you can easily customize internally without a vendor. It reduces the customization time.
  • Easy upgrade: It will be easily and frequently upgradable without any disturbance. You can increase the number of users without cost.
  • Availability of demo: If you want a demo session while implementing an ERP system in your company, you need to contact the vendor, set a time for a meeting and demo session. It consumes more time. But it will not happen with open source ERP because you can get the license through the database that is available publically and examine the software by yourself without communicating with vendors.
  • Quality coding: Open source provides good quality coding because it is built and reviewed by many individual developers. The only thing is your IT team members should check the working of the software process with business data.

Challenges of open source ERP

  • Unexpected expenses: You know that open source code is free. Don’t think you will get everything free. You have to pay for its implementation. Implementation costs consist of hardware charges, software backup charges, internal IT staff, and security charges. If you need external It staff, the charges will be more.
  • Limited features: Vendors offer open source ERP modules. But the fact is they provide limited features with open source code. If you need more advanced or additional features that are required for your business, then you have to pay or subscribe to those features on a monthly payable basis.
  • Needs IT department with advanced knowledge: With the open-source ERP, you only need to design and install the required customization as per your business requirements. For that, you need well knowledgeable ERP expertise. The vendor will not support your technical issues or any crush or error of the software. You have to solve these problems internally.
  • Impression of management: Open source means its source code is publically available. Hence management may be worried about its security. In that case, the implementation team should take responsibility and demonstrate and convince the management about its safeness.
  • Absence of documentation: Open source ERP will be successful with user training. This training session requires some study materials and reference documents. You will get these documents from commercial vendors. But open-source software vendors will not provide such documents. Hence IT team or implementation team should generate training documents to train users adequately.
  • Time and money consuming: Implementation of an open source ERP software is not an easy task. It is a long and difficult process. It requires excess money and time to customize the software potentially. With the help of proper guidelines, planning, and objectives, you may reduce the wastage of time and money.
