The bulk of the project was about creating a wallet section on the Utility Warehouse Clubhouse mobile app. It was an Android and iOS app that allowed customers to view their account at a glance, and make changes quicker and easier than from the web.

The new wallet section had to be many things, but above all else, it needed to be modern, on-brand, and easy to use. The brief was to redesign the UI for the new wallet and make sure it was intuitive, reliable, and compliant with the latest banking security measures.

The project included:

Intuitive wallet user experience
Full UI strategy
Strict compliance and security testing
Agile delivery process

We started with the app’s account and card management system. To build this, we used an agile delivery process. This meant we could update developers early and often and leave a good amount of time for testing, too.

While the brief was on point, there was one thing missing that we felt would be beneficial to the app and Utility Warehouse. And that was the option to block and unblock a debit card with a click of a button within the app. The Utility Warehouse agreed, and so we added this feature.

This project brought a lot of challenges, too. Like implementing 3D secure card transactions within the chosen framework.
Overall, the project lasted around 8 months. We built a strong relationship with the guys at Utility Warehouse and worked in collaboration to get things done on time and budget.

Since completing the app, we continue to work on regular updates and nice-to-have functionalities, such as form validations to help grow the app.

Here’s what they had to say

"The Untapped team are fantastic partners.  We very much appreciated their open, honest and rapid communication — which is a rare find! They can be counted on to provide holistic solutions that go beyond just meeting the initial brief — and they go the extra mile ensure that the end product is truly exceptional."
"I've had the pleasure of working with Will & Untapped on a number of occasions, most recently at Spirit Health Care where a full overhaul of an existing system was needed. Will always takes the time to ensure that the technical requirements of the project and acceptance criteria are fully understood before embarking on any work, and he provides clear communication throughout the lifecycle of the project. The results of such an approach speak for themselves and I would be happy to recommend untapped to anyone looking for a new solution or technical consultancy."
"Untapped were a pleasure to work with from start to finish. Taking the time to understand our brief and asking the right questions to help us achieve not just what we wanted but also what we needed. Will and his team showed a huge commitment to delivering. Producing eye catching designs that are modern and slick, using an intelligent discovery and UX thought process. Clearly technical experts, web development of our new dashboard in Wordpress was a breeze and an enjoyable process to be a part of. We are very happy with the results and would highly recommend."
"I recently worked with Untapped on a complete re-design of my webflow website. The team took the time to deeply understand what I was looking to achieve and constantly keep in touch throughout the design process. The result speaks for itself with a large increase in traffic and inbound leads from the site. I’d recommed the team at Untapped to anyone looking for web development and design."
"Working with Untapped was a pleasure from start to finish. Throughout the project they were great communicators and ensured that we were informed at every step. They grasped our concept at the early stage and planning meetings were really easy and stress free. The quality of the work that Untapped produced was exactly as we required. I would not hesitate to use them again."
"The Untapped team was a pleasure to partner with on some quick-turn deliverables. They were fast and flexible as feedback came in and held themselves to high production standards, ensuring that our final outputs met everyone's expectations."
"Upon launching a new arm of our business, we needed a quality website setting up that was able to integrate with our internal policy quoting systems. As a business that is predominantly built around internal resource and development, it was important that any third-party we worked with was able to adapt to our business and learn our ways. Untapped have proven to be a considerable asset to us, giving us reassurance that third-party companies can have the same level of care, attention to detail, and investment to understanding the core objective as our own teams deliver. A great quality end result too!"
"Will and James at Untapped took the necessary time to understand our product, then delivered a simple and effective app for watching Virtual Reality films on Android and iOS devices. They’ve continued to provide support for our requirements, resolving multiple technological challenges, while also making valuable suggestions for enhancements aligned with business opportunities for us. They are a great team to work with."
"We worked with Untapped on a VERY last minute project and I couldn't imagine a safer set of hands! Our brief to them was scant at best, but they got to the very bones of it with ease. They approached the job with creativity and flexibility, while we were probably the worst kind of client! They made suggestions and slipped into our working methods with ease. The end product far exceeded our expectations and I wouldn't hesitate to recommend Will and Untapped. I look forward to working with them again soon."
"Having worked with Will and the team at Untappd since the inception of my business in April 2020, I have come to rely on the expertise and support that they have provided throughout my journey into e-commerce entrepreneurship. Without their significant expertise it would have been impossible to get my business off the ground so quickly and professionally. I am indebted to Untapped for their continuing support as my business not only expands but thrives within a competitive industry."
"Untapped has been an incredible help to our project from day one. Constantly challenged to find workarounds and creative solutions thanks to a changing tech landscape, Will and his team never let up. And the final product, The Wayback, is now once again helping those living with dementia to relive their past happy memories."
"Web3 is the fastest-paced and most fluid sector I've worked in. We needed a partner who were able to quickly grasp the basis of the project as well as work with the same pace and flex. Untapped nailed this on both counts and delivered a great looking site in a very small timeframe."
"Love it, thanks again Will Yoxall, Glen Saunders and the team at Untapped. If anybody is looking for fast, affordable and quality design work I can highly recommend the team at Untapped."
"Working with Untapped has been a pleasure. Within two weeks we had a fully functioning e-commerce website and were taking our first veg box orders. They've helped us develop our business, providing continual site upgrades, help and direction to create and establish our business plan and providing weekly marketing graphics to aid sales and boost brand presence. We look forward to using their skills and knowledge as our business grows and develops."
