Under the new agreement, wealth management licensees at Commonwealth Financial Planning, Bankwest Financial Advice and Financial Wisdom will move to the Xplan financial planning solution.

The software is already being used in the business and private banking operations of Count Financial and CBA, according to a statement from CBA.

In addition, CBA will become the first company to use IRESS’s new scaled advice platform, Xplan Prime.

Executive general manager of advice, Marian Perkovic, said the aim of the partnership was to provide a simpler and more cost-effective service to clients.

"This investment in technology will help us secure and improve the financial wellbeing of our customers by ensuring all Australians have easy access to quality and affordable financial advice," she said.

The transition will take approximately two years and will bring all CBA advisors to the same platform, the statement said.

IRESS chief executive Andrew Walsh said Xplan Prime provides an alternative to full consultancy services.

"While end-to-end advice will remain an important part of the landscape, many end clients are looking for specific advice or less assisted simple transactions," he said.

Xplan and Xplan Prime were fully integrated systems that allowed advisers to have mobile access, he said.

"Importantly, these channels are interconnected and need to exist across multiple devices, so unifying technology strategies for retail consultancies are key," said Mr Walsh.
