I led the design, from discovery to delivery, of a bill payment solution integrated into our existing gateway platform. This initiative, executed with a cross-functional team, reduced churn by 12% within 90 days of launch.

Context

Pagar.me started as a reliable payment gateway for online sellers in Brazil. As the business grew, the goal shifted:

from just processing payments to offering a full suite of financial and banking tools and becoming an essential part of a merchant’s daily operations.

Opportunity

Our user research showed merchants preferred handling all financial tasks in one place.

But Pagar.me didn’t yet support key daily workflows like paying bills pushing them to competitors and increasing churn risk.

Hypothesis

If we add a bill-payment feature inside the existing dashboard, merchants will keep their entire financial routine on Pagar.me, lowering operational costs for them and reducing churn for us.

Approach

Generative research

Generative research

Facing many open questions, I led qualitative and quantitative research to understand online sellers' core banking needs, their alternative solutions, frictions, and most-used financial management services.

Benchmarking

I analyzed and documented the bill payment experiences of several financial institutions to learn their strengths and weaknesses.

Information Architecture

Designed flows aligned with the user's mental model: bill selection, review details, confirmation.

Wireframes & Prototypes

Tested wireframes early with users and iterated based on feedback around usability and clarity.

First iterations and user testing

After learning the main use cases I started to brainstorm a few solutions and get feedback from the team. After a few iterations I decided to test my solutions with real users
