OVERVIEW
pay.com.au is an Australian B2B payments and rewards platform built for small and medium-sized businesses. Business owners use it to pay suppliers, the ATO, payroll and rent by credit card or bank transfer, even when the payee doesn't accept cards, and earn PayRewards Points on every eligible payment.
With a well-established web app already at the centre of their customers' finances, pay.com.au was ready for its next step: meeting business owners wherever they are.
Their brief was clear. Bring the full web experience to mobile so customers can pay a bill, manage payees and track their rewards on the go, with the same confidence they have at their desk.

PROJECT OVERVIEW



/
WHAT WE DID
From mapping the web platform to delivering a production-ready design system, we brought pay.com.au's payments and rewards experience to mobile. The result gives customers the freedom to pay bills and earn points wherever business takes them, with a consistent experience across web and app and a design foundation ready to scale with the product.

OUR PROCESS
Mapping the web experience
We analysed pay.com.au's existing user flows end to end, understanding how customers add payees, make payments and manage their rewards on the web.
Reimagining flows for mobile
We translated each journey into a native app experience, reshaping steps and hierarchy for smaller screens while keeping familiar patterns for existing customers.
Wireframing and prototyping
We wireframed the core journeys and built interactive prototypes in Figma, bringing the app to life before a line of code was written.
Testing and refining
We put the prototype in front of real users, observed how they paid on the go and refined the experience around what we learned.
Building the design system
We created a design system library from scratch, giving pay.com.au a scalable foundation of components and patterns, then handed over to development with everything needed to build with precision.
