Commercial Open Source Software (COSS) offers some elements of openly published free software, but enhanced capabilities such as enterprise and interface functionality is available only as closed software with fees.

"Dual-licensed open source" is an administration method whereby companies provide software with open source licenses and also license the very same code with a proprietary license for organizations whose procurement systems require one. The principle with dual-licensed software is the same: it can be FOSS if all versions are made available in a FOSS license approved by the OSI.
