Supervoice is an invoicing app which started out as a side project to test my abilities, learn new things along the way and create an application that I could use in my day to day life.
Throughout the journey, I could see the value it would have, so I decided to turn it into a SaaS product, that would be perfect for freelancers and small businesses.

Brand Identity Horizontal
Collaborating with Joe Taylor on the brand identity, we created a timeless brand mark that is formed from the first letter S and has stacked paper (invoices).
Paired with a beautiful sans serif typeface and vibrant colors, allows us to create beautiful and readable interfaces.

01
The largest part of the UX strategy is defining the structure of the website and app. I began with a small sitemap, a single homepage for the marketing website, then the app with the internal pages accessible only by logging in.
In addition, I create user journeys for specific actions, to make sure all criteria is covered and user goals are being met.

02
Content flows is something that I have found crucial to creating a successful story for each page on a marketing site. And I adapted it to work with web apps as well.
Once I had mapped out what sections I wanted within the marketing site and app, I began crafting some words then taking that into design.

03
The fun begins. Part of the brand story, I explored a couple of ideas that took me into a 3D environment. I came up with the idea of a scene with multiples buildings and crossroads, and instead of cars going from one place to another, it would an invoice. With the added car-like animation added to each invoice as they hit the traffic lights, it really brings it to life.

04
I decided to do the marketing site and app as separate builds. However, both are built in React / Next.js.
The app however, I built it twice. First version using Firebase, then I decided to refresh the UI and rebuild it using Supabase. The only for this was to learn a little backend and also see which would be more comfortable to continue with.

One of the simplest invoicing platforms I've ever needed. LOVE the UI! Hoping to have payments implemented and that'll do everything I need.
