Abstract: Systems, methods, computer systems, and computer-readable code for implementing methods for client relation management in which fewer call-in numbers need to be maintained. A method for client relation management preserves a more-complete record of online and offline interactions of a customer with systems provided by a plurality of service providers. A session identifier (SID) is associated with a customer upon interaction of the customer with a website provided by a first service provider. Website interaction information is received from the first service provider and is associated with the SID. Information associated with an incoming call from the customer at a call-in number at a call center maintained by a second service provider is used to associate the incoming call with the SID, creating a record of an offline interaction between the customer and an agent of the call center. The record of the offline interaction is associated with the SID.
