The rise of the cloud has made it necessary to distinguish between solutions that are hosted and solutions that are installed on location. This distinction requires a term for the latter – and “premises-based” or “on-premises” are what we often use.

They are great words that, unfortunately, are frequently misspelled, “premises” being erroneously replaced with “premise.” “Premise-based” or “on-premise” appear everywhere, from help forum posts to UC magazine articles to analyst white papers. But “premise” and “premises” are two very different words:


plural noun
A house or building, together with its land and outbuildings, occupied by a business or considered in an official context:

  • The company has moved to new premises.
  • Alcohol is not allowed on the premises.
  • [treated as singular] The three had negotiated a lease for a premises in Boothstown, Manchester.



singular noun
Logic – a previous statement or proposition from which another is inferred or follows as a conclusion:

  • If the premise is true, then the conclusion must be true.

An assertion or proposition which forms the basis for a work or theory:

  • The fundamental premise of the report.


“Premises-based” refers to a solution that is based in your physical location. A “premise-based” solution would be one that is based on an idea or logic – which, ideally, would be true of any solution, hosted or not. And does happen to be true of Mitel’s solutions, which range from hosted to premises-based to everything in between.
