Benefits of open source ERP
Reduces costs
If your organization is small or a startup, you will not be able 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 customize 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 must 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. As a result, it reduces the customization time.
Easy upgrade
It will be quickly and frequently upgradable without any disturbance. So 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 must contact the vendor and set 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 publicly available database and examine the software 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. But, 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. Of course, 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 required for your business, 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 challenging process. Furthermore, 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.
Please suggest to us how we can make this list of open source ERP better.
