UI Viking | Alex Borisson | Car Wash POS

Product design

The handheld POS built for car washes

One of my biggest project for the car wash industry. Nine months of fascinating and hard work. Weeks of research, 480 hours of design and 300+ screens.
Working hand in hand with the Android developers for more than 6 months. 2 months of testing and debugging and finally release on PAX STORE.

Introduction

My goal was to re-build the outdated .NET Core Car Wash POS System used on more than 2000 car washes across United States.
Switch POS to Android handled devices and keep the “evolution, not revolution” concept for wide range of the Android devices from PAX.

The Old Version

These are just a few screenshots of the old version of POS. I believe that was designed back in 2000. The POS was user-unfriendly, buggy and slow.

The Target Audience

Car wash managers and attendants are the target audience for this product. And there were a few things I had to keep in mind:
  • UI Viking | Alex Borisson | Car Wash POS
    Some tunnel and in-bay car washes have up to 1000 vehicles a day, so the employees can be in real rush;
  • UI Viking | Alex Borisson | Car Wash POS
    The elements on the screen have to be a bit bigger, so car wash employees can easily tap on any element when they are in rush;
  • UI Viking | Alex Borisson | Car Wash POS
    Car wash workers can take the device outside;
  • UI Viking | Alex Borisson | Car Wash POS
    And of course, the interface have to be clean, intuitive and user-friendly.

Mind Map & Wireframe

Firstly I had to understand all business logic and processes, so I spent a few weeks using the old POS and made a massive document with the notes.
And only then started mind mapping and got to the wireframing.

Mock-ups

At first we were planning to use PAX E600 only, so I started from the vertical layout for the 8-inch 800x1280px screen.
Later on, top management decided to add one more device and that’s where landscape layout started.

On The Go

Since a lot of car washes were using previous POS software for more than 10 years, I had to keep the same core features:
  • UI Viking | Alex Borisson | Car Wash POS
    Read & save license plates (we use Open ALPR);
  • UI Viking | Alex Borisson | Car Wash POS
    Subscribe customers for the unlimited plans;
