Year

2018

Focus

Research, product strategy, prototypes, interface design, and launch.

The Solution

Transform complexity into productivity

Equals helps companies understand sales, taxes, and payment flows across many banks and acquirers. We used an explainer video early on to make the product easier to understand for clients and internal teams.

Clear framing first. Interface decisions second.

The Problem

One merchant, many moving parts

The credit card market is full of different machines, contract rules, and tax rates. For business owners, that means more doubt, more manual checks, and more stress. The app needed to reduce that noise.

Many acquirers

Stone, Cielo, Rede, Getnet, and others all behave a little differently.

Many sales types

Debit, credit, installments, and other sales rules all affect the final numbers.

Many tax rules

Each contract changes what the merchant receives and when the money arrives.

The Process

A simple structure for a hard topic

1. Research

Competitor review, field interviews, user canvas work, and surveys.

2. Ideation

Information architecture, feature framing, MVP definition, and first sketches.

3. Validation

Low and high fidelity prototypes tested with internal and external users.

4. Development

Close work with developers on alpha, beta, and adjustments from real feedback.

5. Launch

Final polish, support material, onboarding, and app store delivery.

User Survey

Start with what people struggle with

We mapped frustrations, needs, and expectations with surveys and follow-up calls. That gave the team a shared view of what really needed to be fixed first.

Work In Progress

From research to testing

The Final Result

Simplicity is the result of hard design work

After several rounds of testing, the product reached a dashboard that gives merchants a broad view of transactions without exposing all the backend chaos. The complexity is still there, but the user no longer has to carry it alone.
