Big Data Analytics then came to their rescue. Through analyzing their customer’s data from a variety of sources such as their website, call center logs and personal feedbacks, they discovered that their end-to-end cash management system was too stiff for the customers as it hindered their freedom to access trouble-free and flexible cash management system.

Though smaller banks were offering an effortless solution to it. Ultimately, they decided to end their all-in-one offering.

Soon in the year 2009, as a solution to these problems, they launched a website that was a more flexible online product, CashPro Online, and its mobile version, CashPro Mobile later in the year 2010. This was developed with an aim to provide their customers with a one-stop solution for all the services they offer.


With huge amounts of data comes endless opportunities for all kinds of businesses across different domains to exploit that data, and the banking sector is amongst the most benefitted ones. The data that the banking firms collect is as critical and as valuable as anything else for them.
