The Problem

46% of new users and ~29% of returning users abandon their purchase at the payment step, hurting conversion and delaying repeat purchases.


Over the last 12 months, nearly 46% of new users and 29% of returning users dropped off at the payment step—after selecting a payment method and entering their details—leading to significant conversion losses and an extended time to second purchase.

Other clear indicators of friction emerged, reflected in:

01

Average days to second purchase - 27 days

Asking the right questions

How might we

Simplify the product and payment experience so users can complete purchases effortlessly, with fewer steps and less mental strain?
Build stronger trust signals and clearer reassurances at the payment step to help new and returning users feel safe, informed, and confident enough to complete their purchase?
Detect, prevent, and clearly communicate errors during checkout so users can recover instantly instead of abandoning their purchase?

Listening and learning

Gathering insights

I conducted usability research with 18 participants from Nigeria, Egypt, Kenya, and Morocco who had made zero or fewer than five purchases on the Carry1st Shop within the previous four months to uncover key pain points.

I ensured regional diversity by including a 25% representation from MENA.

During moderated sessions with each participant, I measured their time-on-task, error rate, and task-completion rate across both the product and payment pages.

What I did next

I conducted a thematic analysis on the raw test data to highlight the trends and patterns. After completing the initial usability research, I developed high-fidelity prototypes incorporating the recommended UX improvements and conducted a second round of testing with each participant, measuring time-on-task, error-rate and task-completion rates and comparing them with the first-round results to assess measurable gains in usability.

I also administered a System Usability Survey to capture quantitative insights into the usability score before and after the improved designs were introduced.

I then partnered with the PM and engineering lead to determine the implementation priority for each design output, ensuring we addressed the most critical pain points efficiently.

Redefined structure and information architecture

I began by redefining the product detail page’s structure and information architecture to reduce cognitive load, highlight the most important purchasing cues, and streamline the checkout process.

Progressive disclosure with intuitive flow

Next, I replaced the lengthy, hard-to-scan page with a structured, progressive flow supported by strong CTAs, helping users focus on the right actions at the right time.

Embedded payment forms

Previously, users selected a payment method but saw no form, leaving them stuck on the page and unsure how to proceed. The improved UI embeds the payment form directly after selection, guiding users seamlessly without extra clicks or navigation.
