    Very open source. It has a lot of modules to manage any kind of organization. The UI is simply fantastic and it's pretty darn fast!

    Functionality is matched quite well with a near one-to-one module correlation between the two. For my needs, the MRP module is a MUST. I actually liked ERPNext's manufacturing setup more that ODOO 10.
