# Rate Card Versions

Rate Card Versions represent a snapshot of a Rate Card at a specified point in time. They are used to set the
default rate. Rate Card Versions belong to a Rate Card Set Version and own many Rate Card Roles.

Rate Card Versions cannot be explicitly created. This is done through the creation of Rate Cards or
Rate Card Set Versions.
