ERPNext’s simplicity means that it’s easy to set up, using simple forms to enter information about your business and walking you through the whole process in typical setup wizard style. It’s a feeling that quickly becomes familiar as the ERP is clean and user friendly.
Of course the downside is in expanding the ERP to fit specific needs for larger or more complex businesses. While there are built in tools for designing specific forms and reports, adding more complex elements requires diving headfirst into the code.
ERPNext is free for five users when hosted online, or free for any size business when installed on your own servers.
