Ensure Standardisation:

Archetype documents use a consistent house style without any need to specify fonts, tabs, indents, logos, etc. and all have a unique document reference.
Users do not need to be concerned about formatting a document when they create it. Simply enter the required information and print the document, no filename, folders, templates or formatting to get in the way.

No matter who produces the document you get a consistent layout including your choice of fonts, logos, etc.
