Instant payment app

Project background

The coronavirus pandemic forced big and small businesses to adapt to unprecedented circumstances in 2020. Technological solutions offered a variety of options to both support end users and help businesses overcome the negative economic impact of the pandemic. The telecommunication industry was no exception. 

According to Statista research, in 2021, technology spending in the telecommunication services industry grew to 1.45 trillion U.S. dollars, with an increase of nearly 5% from 2020. 

Our client, a well-established UK telecommunication company, was looking for a reliable software vendor to help develop native mobile applications for iOS and Android users. This instant payment app included integration of all telecom-related finance operations into one solution for customers’ comfort.  

Business needs
