This project reinforced the importance of designing payment experiences around reassurance, not just transaction completion. For SNAP customers, checkout is not simply a final step in the purchase flow; it is a moment where unclear balances, credits, or remaining charges can create real anxiety. By testing with eligible shoppers and closely examining how they interpreted the ledger, I learned how small hierarchy and labeling issues can undermine trust when users are managing constrained benefits and multiple payment methods. I also learned that high-impact research does not always require broad, open-ended discovery. With a tight go-live timeline, the value came from focusing the study on the riskiest moments in the experience, translating confusion into specific design changes, and helping the team prioritize improvements that could ship quickly. The work showed how targeted usability testing can clarify complex edge cases, reduce customer uncertainty, and improve confidence at a critical point in the shopping journey.
