ERPNext is released under the GNU GPLv3 license. Consequently, ERPNext does not require license fees as opposed 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 "Frappé"  and is maintained as a separate open source project. Frappé started as a web based metadata framework inspired from Protégé though it has evolved differently.
This architecture allows rapid application development (RAD).
