A significant advantage to choosing an open-source solution like ERPNext is the ability to easily customise and extend the software to give your business an edge over the competition.

frappe have done an excellent job in making the framework and therefore ERPNext extremely flexible when it comes to customisation. For example you can do the following:

1. Create custom fields, server (python) and client (javascript) scripts and save them from the cloud UI. This makes small modifications extremely fast;
2. For larger changes, create apps that sit on top of frappe and ERPNext to add to or even override the default behaviour without modifying the vanilla code. This makes upgrades later much easier and allows you to deploy your code and therefore business multiple times;
3. If required you can also start fixing bugs and enhancing the original open-source projects.
