If you think of Flappy Bird and Facebook when someone mentions smartphone apps, it's time to think again.
More and more businesses are using apps to improve productivity and their connection with customers and clients.
The IRD has joined in, with the App4IR Challenge, hoping to find a mobile app to connect to the Government department with its 420,000 small-business customers.
The winner will get $10,000 for the design and an opportunity to collaborate on the development of the app, which will be funded by the IRD.
The best app ideas will be selected and presented to a panel of judges. IRD is collaborating with Creative HQ, the business startup incubator on the project, to encourage creative entrepreneurs to step forward.
