Expert data migration services for investment management firms
CSSI over the last 15 years has done a number of system merges into Axys/APX and other systems. With the acceleration of acquisitions in the market place CSSI has completed a number of large and small conversions in a matter of weeks on small ones and in a few months on larger ones. CSSI has also completed a number of move to other systems from Axys/APX. When thinking about your system merge or data conversion there are a number of tasks and analysis that needs to be completed. CSSI can project manage, perform the project, or assist your firm.
Timely and accurate data for your portfolio management system
CSSI Solutions knows that a portfolio management system without timely data is not very useful. Over the years, we have established our own direct feeds and worked with partners to assist in data aggregation.
CSSI's Trevport utility can be used with any datafeed that the customer has access to for prices, positions, transactions, and more. It is CSSI's swiss army knife data utility.
BAA has thousands of direct and indirect feeds that can be used in your portfolio management system and continues to grow the list regularly.
WT has done an excellent job of pulling together a large number of custodian relationships which cover a large portion of the custodial universe. WealthTechs also provides flexible custom development in a timely manner.
Comprehensive BackOffice Services with ByAllAccounts integration
CSSI's ByAllAccounts (BAA) BackOffice Services offers a one-stop source for reconciliation outsourcing and data needs. This offering can apply to a portion or to all of your accounts.
Through CSSI's relationship with BAA, the customer won't need to pay the annual Custodial Integrator fee. The customer will pay for all BAA data feeds and for reconciliation services only on the accounts that are active.
Data projects often spill into consulting, back-office operations, or cloud hosting once the migration touches workflow, reconciliation, or infrastructure decisions.
