Typefaces in their digital form are products distributed and sold like software: it is not the design itself that is sold, but a copy (a font) attached with an agreement to use it: its license.

A license contains terms and conditions granted by the designer and/or the publisher to use the font. There are multiple types of licenses adjusted to the intended use of the potential client. There can be different licenses, with a pricing system specific to particular distributors, according to their marketing philosophy.
