Mobile Checkout

Product Design
Project Overview
This project is a redesign of the checkout process for a second-hand e-commerce platform in Brazil. The website offers two purchasing methods: directly messaging sellers via chat or buying online like a traditional e-commerce store. The main goal of this project was to improve the mobile shopping experience and increase conversion rates on mobile devices.
My Contributions
As the team's Product Designer, I was responsible for analyzing the usage of the checkout, gathering quantitative and qualitative data from users, exploring solutions in both low and high fidelity, designing the interface and new components for the page, and building the interactive prototype.

Data analysis revealed that mobile checkout had a lower conversion rate than the web, despite over 50% of users accessing the site via mobile. With the increasing trend of mobile shopping, this project aimed to optimize the checkout experience to reduce friction and improve conversions.
Payment Methods
The ideation process generated several hypotheses, which were prioritized to introduce small, continuous changes. These changes were tested in isolation to ensure they did not negatively impact the existing conversion rate.The testing began with the payment methods interface, as we had received numerous user complaints stating that the site only accepted Pix payments in a single installment. This was because, by default, new customers were presented with Pix as the primary option, as it was the most cost-effective for the company. However, for users who had previously made purchases using a credit card, the credit card option was displayed instead.
Delivery Methods
Delivery is a crucial part of the online shopping experience, and giving customers the ability to choose the method and timeframe for receiving their products can be the difference between repeat purchases or abandoning the site altogether.By default, the estimated delivery time shown to customers is 8 business days—a lengthy timeframe that accounts not only for the logistics partner’s delivery period but also the time the seller has to ship the product.

With the addition of new logistics partners in certain regions, we introduced two new delivery methods: Express, with delivery in 3 business days, and Lightning, with delivery in just 1 business day. Displaying all available options enhances the shopping experience, allowing our delivery times to better compete with other e-commerce platforms.
Stepped Checkout
The tested hypothesis is that a step-by-step checkout experience provides a more focused experience for mobile device users by presenting each task separately on a dedicated page. This approach makes it easier for users to complete the necessary actions at each stage more smoothly, avoiding the modal pop-ups that frequently caused errors and a fragmented experience in the one-page version
Future View
The future vision for the checkout aims to redesign flows that, due to technical constraints, could not be prioritized at the time. This includes the flows for adding payment cards, adding addresses, and improving the pickup process for products directly from sellers or lockers.
