BackOffice Overview

CSSI’s BackOffice Services act as a firm’s in-house operations outsourced as a reconciliation staff (or staff supplement). The services include daily account reconciliation, entry of paper statements, price and index updates and backup of audit trails and logs. CSSI administers the services remotely on the customer’s system, which allows the customer to maintain control of both the operation and the data.

CSSI does not host any of the customer’s data but rather performs the daily download and reconciliation directly on the customer’s system by connecting securely via the customer provided secure remote connection.

This setup is advantageous to the customer as it allows them to maintain control of the operation and the data, rather than having to conform to a standard setup over a hosted application.
