commercial software
commercial off-the-shelf software

    (Or "commercial off-the-shelf software", COTS)
   Software that is produced for sale.  This contrasts with
   free software, which is produced for free distribution,
   meaning without charge and/or without restriction on further
   distribution.

   Some companies that sell software distribute some (versions)
   of products free of charge (but usually with restricted
   distribution rights), this would probably still be called
   commercial software.  Conversely, software that an individual
   distributes for free, but for which he accepts donations,
   would still be called free software.
