Under the agreement, Count will replace its aging proprietary wealth management system WealthPlanner with IRESS' XPLAN platform.
WealthPlanner was developed in 2000, and is due to be decommissioned at the end of next year.
Implementation of the XPLAN system will begin in early 2011, with the rollout tentatively scheduled for March.
Count CEO Andrew Gale said IRESS had been chosen as a partner after an extensive review of available software.
“Ultimately it was clear that XPLAN could provide the integrated and adaptive solution we were looking for,” he said.
Count has estimated that adapting XPLAN can help it increase productivity of active processes by up to 50 per cent.
IRE shares closed 1.58 per cent higher at $8.990, while COU shares grew 0.79 per cent to $1.280.
