Found a nice explanation here:
In addition to the authentication and authorization process, an extension of
the RADIUS protocol provides an accounting function. Typically, when a user
logs in, the Network Access Server (NAS) sends an "accounting start" record
to the security server in order to signal that an accounting session has
started. When the user logs out, the NAS sends an "accounting stop" record
to indicate that the accounting session has ended. This record contains
information about the amount of time used, data sent and received during the
session, and other relevant billing information.
You can configure the NAS to send accounting records to a server for both
standard and RADIUS users. This is a guaranteed service - each request is
acknowledged by the server, making it a reliable way of gathering user
access information.
