The hypotheses and assumptions

The hypotheses and assumptions

The hypotheses and assumptions were informed by the founders' and investors' vision, the designed MVP, user feedback regarding competitors, as well as the needs and pains of the companies.

Research Hypotheses

  1. Centralized Financial Management Improves User Efficiency
    Hypothesis: A mobileapp th at centralizes bill registration, payment tracking, and financial planning will help users manage multiple bills more efficiently and reduce the likelihood of missed payments. (VALIDADED)


  2. User-Friendly UI Enhances Engagement and Retention
    Hypothesis: A redesign that emphasizes quick interactions (via card systems, big number displays, and intuitive calendar integrations) will boost user engagement, shorten the learning curve, and increase daily/monthly active usage. (FOR VALIDATION/INVALIDATION)

  3. Automated Reminders and Personalization Drive Payment Compliance
    Hypothesis: Incorporating features like personalized notifications, automatic renewals for recurring bills, and customizable interfaces (themes and category organization) will improve the rate of on-time payments and overall user satisfaction. (FOR VALIDATION/INVALIDATION)

  4. Heuristic-Based Design Reduces Errors and Increases Trust
    Hypothesis: Applying Nielsen’s heuristics (e.g., “visibility of system status,” “error prevention”) in the UI design will minimize technical issues such as double charges and unintended actions, thereby increasing user trust and reducing support demands. (FOR VALIDATION/INVALIDATION)

  5. Integrated API Solutions Benefit Business Clients
    Hypothesis: Offering robust API integrations for companies—allowing them to embed bill management functionalities within their existing systems—will attract a significant portion of the B2B market and drive a new revenue stream. (VALIDADED - 2024)



Research Assumptions

  1. Market Readiness and Adoption
    Assumption: A substantial segment of the Brazilian market, with over 150 million internet users (of whom an estimated 50% are economically active), is in need of a digital tool to simplify bill management. (VALIDADED)

    Assumption: The growing mobile adoption trends and digitalization in Brazil create a fertile environment for such a product. (VALIDADED - OUTSIDE BRAZIL TOO)

  2. Pain Points in Existing Bill Management Solutions
    Assumption: Current solutions suffer from issues such as disorganized bill tracking, technical glitches (e.g., double charges, lack of support), and non-intuitive interfaces that confuse users. (VALIDADED)

    Assumption: Users and companies are seeking tools that not only consolidate bills but also provide advanced functionalities like detailed reports and financial planning. (VALIDADED - FOR B2B)

  3. Financial Viability Through Subscription and Commission Models
    Assumption: With even a modest market penetration (e.g., 1% of individual users and 20% of companies), the revenue models—whether through monthly subscriptions or per-transaction commissions—are financially viable. (VALIDADED)

    Assumption: Both traditional users and business clients value the convenience and potential cost-savings offered by a streamlined, integrated solution. (VALIDADED)

  4. Design Choices Impact User Trust and Intuitiveness
    Assumption: The use of established design principles—such as an 8-pixel grid, clear visual hierarchies, and a color scheme (e.g., purple for trust, green for OK statuses)—will make the app feel secure and intuitive. (VALIDADED)

    Assumption: Typography choices and adherence to consistent standards contribute to overall user satisfaction and ease of use. (VALIDADED)

  5. Improvement Metrics Will Reflect Design Success
    Assumption: Key performance metrics such as DAU/MAU, conversion rates (from bill registration to payment), and user satisfaction scores (NPS) will improve post-redesign, reflecting the effectiveness of the UI enhancements. (VALIDADED)

    Assumption: Tracking user journeys through defined funnels (onboarding, payment, retention) will reveal areas of success and opportunities for further refinement. (FOR VALIDATION/INVALIDATION)

UI Analysis

The MVP

The first version of the product was designed with the sole purpose of receiving the bill. This prototype was a great success, and the startup was delighted to secure the first round of investments. They then set about thinking about how to improve the product, focusing on two key areas: the architecture and the overall design.

The Home

The home is the heart of this product. It's where the magic happens! With it, the user has a bird's eye view of all the main functionalities, which help them tackle problems and interact quickly, boosting their productivity. So, we're giving the home a makeover to bring something more relevant and competitive to the market!

Home Mapping

Home Mapping

Once I'd done all the research and analysis, I started to map out the old journey, which would be the basis for the new one. I focused on the points for improvement that had been raised previously in the research and analysis.

The Design Solution

The Design Solution

We really focused on the main points of the brief and tried to resolve all the problems related to it. We'll take a look at the solution point by point, so you can see exactly what we did.

The visual solutions and the whys

Why did I design the solution this way?

SourceSans Pro is excellent for apps due to its high legibility across screen sizes. Its neutral style and wide language support offer versatility. Being open-source makes it a practical choice for developers. Futhermore, this font it’s defined in the Conta Comigo brandbook for usage.

Typography

This kind os solution is based on two of the Nielsen Heurístics, the “visibility of system status” and the “consistency and standards”

Heuristics

This kind of solution is based on two of the Nielsen Heurístics, the “Error prevention” and the “consistency and standards”

Heuristics

8-pixel spacing is a standard in design and market, because it looks good, adapts well, easy to scale, and is easy to use.

Spacing: 8 Pixels

Purple is the primary color defined in the Conta Comigo Brandbook and it’s direct related to the trustworthiness and calmness.

Main Color

The other colors follow the market standards and the heuristic “Consistency and Standards”, like “Green for OK” and “Yellow for Attention”, helping the user to use the solution intuitively.

Other Colors

Home interactions

Home interactions

The home is the heart of this product. It's all about making your life easier! With it, you can see all the main functionalities at once, so you can quickly deal with any problems and get on with your day.

Home + Menu, user name and Notifications icon.

We made sure to place the menu where our customers would find it most convenient based on some market research I did.

The menu area has its importance, but in validation meetings, the stakeholders wanted to maintain it on the top more discreetly.

The “menu” writing was maintained considering the new phase of this product, and based on a “safe play” to help the user clearly understand what is/where the menu is.

Calendar + Big numbers

I've designed both to be easy to use, following the concept of the carousel components. This makes it super simple to keep on top of your bills soon!

The two carousels work independently, but the calendar is the main link. It influences the big numbers and the view of the card's bills, so it's a vital part of the system!

Notifications

and Alerts

Here we have the market standard that helps the users quickly remember if a bill is coming closer to the payment day.

And other information about the connection with new companies selecting the Conta Comigo to send their charge to the user.

Filters

More market standards about the filter functionality with some additions based on the context of the app.

Calculator

This is a special functionality that helps the user to calculate specific bills they want by pressing and holding one bill and unlocking the selector.

They also can mark multiple bills as paid.

Delete and Archive

Another special functionality is the quick action for deleting or archiving a bill by sliding the specific bill the user wants to right. The Toast with the option to cancel the action is related to a heuristic of error prevention.

Mark as Paid

The same slide functionality exists. For marking a bill as paid, the user just have to slide the card to the left.

Pop-up

The pop-up it’s another important functionality that helps the business and marketing to offer promotions or ask the user to accomplish a specific action.

Home Heat Flow

Home Heat Flow

With more information, we need more caution with the overall structure of the flow, so the understanding of some areas was necessary.

By including more possibilities in the app’s home screen, the flow needed to be carefully rethought.

The calendar was shortened to give more room for the carousel of information with big numbers (important for the users) and give more space for the cards.

The filter system received a good space directly above the cards.

The menu and notifications were shrunk a little but without prejudice in overall perception.

The input bill button now has a fixed area at the bottom of the screen.

The screen rhythm now follows a more fluid sequence thinking in a way that every part has its importance, but, trying not to invade the different zones.

Validations about Handoff

Validations about Handoff

While the designs are being created, I sometimes needed to chat with the front-end team and the architect to get their input. They're great at suggesting alternatives to help us work around any technical limitations we might face with the technology we're using in this project.

Once we've got their seal of approval, the designs go for final validation with the startup owners and investors. If all goes well, we hand them over to the development team and get started on the design documentation.

About Metrics and Funnels

To ensure the success of the app, it's crucial to define metrics and funnels that monitor and optimize the user experience while evaluating the solution's financial performance. Here are the key recommended metrics and funnels that we define while the product is designed:

Metrics Management Suggestions

Acquisition and Activation

Number of downloads: This will help the marketing team understand the effectiveness of the marketing campain

Activation Tax: This will help understand what is the % of the users that download the app and completed the sign up flow and started the app

Engagement

DAU and MAU: Helps to understand how many users use the app daily or monthly, this reflects on the engagement.

Retention Rate: % of users thath keeps using the app after a defined period of time (ex. 7 days, 30 days, 90 days, etc).

Usage Frequency: How many times a user acess the app for a spectif period.

Session time: How long the user stay in the app for each session.

Conversion

Conversion tax for payments: % of bills that are payed through the app.

Avarege time for the first payment: How long a user takes from the sign-up flow to the first payment.

Monetization

Average Revenue per user (ARPU): Revenue generated per user for a period of time.

Acquisition Cost per User (ACU/CAC): How many cost to acquire a user that really uses the app for pay they bills?

Lifetime Value (LTV): Total value estimated generate by a user in they whole lifetime in the app.The total value estimated by the app for a user's whole lifetime

Support and Satisfaction

Churn Rate: Percentual of users that left the app after a certain period.

Net Promoter Score (NPS): The probability of users recomend the app for other people.

Time for Support Resolution: Average time to solve user's problems.

Funnels

Onboarding

Steps: Download > Sign Up > Onboarding > First bill registration

Objective: Understand where the user is dropping off and optimize the activation testing solutions to improve the retention in this moment.

Payment

Steps: Bill resgistration > Bill visualization > Payment journey > Payment finish

Objective: Monitor the conversion in each step of bill payment journey to understand where are the barriers that can help the conclusion.

Retention

Steps: First use > weekly recurring use > monthly recurring use >

Objective: Evaluate the usage of the product and includestrategies to improve rentention.

About the Components

About the Components

All elements in the app were componentized. Because in my context I've worked solo on this project for 5 months, and the project focus was related to reducing the time to market at the extreme, I just did the basic structure directly in Figma with proper documentation to help the devs code the components more quickly
