A system for updating parameters of financial transactions associated with
financial services initiated and completed on behalf of or directly by a
user through access to a data-packet-network into more than one
electronic interface accessible to the user is provided. The system
comprises, a main electronic interface supported by back-end software,
the main interface for registering all user accounts into at least one
portfolio group, the accounts accessible in detail through the main
interface, at least one cobranded electronic interface supported by
back-end software, the cobranded interface mirroring the accounts
registered in the main electronic interface and a plurality of
institution-specific electronic interfaces for providing direct account
registration, reporting, and maintenance specific to accounts provided by
the associated institutions. Through direct linking between the main,
cobranded, and institution-specific interfaces, any parameters associated
with any action initiated to a specific account through any of the
interfaces is immediately propagated to the other interfaces.
