Aruba E-invoicing App

Project overview
Aruba E-invoicing app is a single page app.

Team
I designed it from the ground up.
Up to 3 designers on call.

My role
UX designer - UI designer - Lead designer

When
From 2016 to present.

Problems

Aruba’s E-invoicing software (used for invoicing public administrations) had high support costs due to poor design.
The company plans to redesign it to reduce these costs.

Curiosity

The project manager handed me a project document and told me to start designing it. With ~150k active users, I requested a 6 weeks to conduct user research to create a better experience, suited to their needs. Aruba was known for its low prices but not for the usability of its solutions.

First research iteration

I created a survey to understand the pain points in the current solution.

I requested a set of queries to run on the current database to understand actual usage and identify the personas.

Research insights

People do not understand the terminology specific to electronic invoicing.

The information architecture is unclear, and users cannot find invoice drafts.

Second research iteration

I ran a competitor analysis in Italy and other countries.

I ran a research on the best form-filling patterns.

The idea

I made sketches of the new information architecture and the new invoice creation UI, and I validated them with various types of stakeholders, iterate to the final solution.

I created wireframes using Adobe Illustrator and assembled them on InVision.

Testing

I tested the proposed solutions internally and with real users, running several user testing sessions.

I iterated the design process three times until reaching the final solution.

Testing insights

The assisted input and out-of-focus validation patterns are appreciated by users, as they help prevent errors or resolve them immediately.

The new information architecture is clear and easy to understand.

Users appreciate the table filters, designed similarly to Excel, as they are used to it.

Results

Goal

Six months after the release of the new version of the software, support costs decreased by 80%.

Curiosity

The Italian government decided to extend the use of electronic invoicing to all companies, and our software was easily adapted to include this functionality.

Product growth

Research

We run surveys to understand user satisfaction, their needs, pain points, and to test new business ideas.

We analyze feedback daily, clustering and measuring it against each other; this helps guide the roadmap.

Testing

When we introduce new design patterns or complex features, they are first tested with users.

Results after 7 years

+ 1M users

We have over one million paying users.
We have grown by 614%.

Design win

A Nielsen study states that the primary reason for purchasing the product is its simplicity, with price being the second reason.

Rating

The company’s most complex product has the highest CSAT (4,6) and MOOD rating (3,2).

Modules

We have created 4 additional modules, making the product an almost complete management system.
