To be integrated in October 2014, the tool provides downloadable bank accounts for its customers.
Westpac customers will be able to track their spending through real-time mobile receipts that will be received immediately after purchasing a product.
In addition, they can compare their average spend against their actual spend for a month through a graph that uses colors such as red, yellow and green to show the difference.
Westpac chief digital officer Simon Pomeroy said: "The key to this set of features is the ease of use.
"It is developed with the digital age and the mobile consumer in mind.
"There is very little manual set up, it comes preloaded with 12 categories and other features and the way graphs are displayed delivers quick and effective budget and money management information in real time."
The integrated system will also provide customers with regular feedbacks and money management decisions.
Moven founder and CEO Brett King said: "Our objective is to get as many people as possible around the world using our tools everyday.
"When you are talking about providing banking services, however, that also requires great bank partners in those markets where we launch. Our partnership with Westpac is yet another example of their commitment to world-class innovation."
