Osu

Osu supports sole traders with a business management and payment app integrated with accounting software. The client initially asked us to design and develop the front end for their open-banking service, including a payment widget and admin system. Yojji delivered a widget and dashboard for merchants to track payments, manage users, and customize features. After a successful MVP launch, we continued developing an app to create and track payment requests. Today, we’re actively enhancing the mobile app with new features.
