ERPNext is released under the GPL. Consequently, ERPNext does not require license fees, which is a difference compared to proprietary ERP vendors. In addition, as long as the terms of the licenses are adhered to, modification of the program is possible.
ERPNext has a Model-View-Controller architecture with metadata modeling tools that add flexibility for users to adapt the software to unique purposes without the need for programming. Some attributes of the architecture are:
- All objects in the ERP are DocTypes (not to be confused with HTML DocTypes) and the Views are generated directly in the browser.
- Client interacts with the server via JSON data objects on a Representational state transfer (RESTful) supporting server.
- There is ability to plug-in (event driven) code on the client and server side.
The underlying web app framework is called "Frappe"  and is maintained as a separate Project. Frappe started as a web based metadata framework inspired from Protégé though it has evolved differently.
This architecture allows rapid application development (RAD).
Source Code and Documentation
A complete user manual is available at the project website.
The core innovation has been in the metadata modeling which provides for flexible use of the application without custom programming.
The user interface incorporates usability enhancements designed to improve ease of use and user productivity.
Software as a service
erpnext is available as a Software as a service in addition to user-hosting.
ERPNext provides an embedded reporting system with office suite integration. Report customization is available within ERPNext.
A key weakness of ERPNext is there is limited automated testing. Since August 2011, developers are adding Test Cases to enhance automated testing.
Additionally, user documentation is weak and the application does not currently follow any documented standards for data modeling.
