Problem Framing
Context
Our e-commerce platform was experiencing a 68% cart abandonment rate—significantly higher than the industry average of 55%. Customer support tickets revealed confusion around shipping options, hidden fees, and trust concerns during payment.
Goals and Success Metrics
Reduce cart abandonment rate from 68% to below 50%
Increase checkout completion rate by at least 20%
Reduce average checkout time from 4.2 to under 3 minutes
Constraints
8-week timeline
Existing payment gateway integration
Mobile-first approach required
WCAG AA compliance
User Research and Insights
Research Methods
User Interviews
15 participants
Analytical Review
3 months data
Competitive Audit

Key Findings
Unexpected costs
"I got all the way to the end and then saw a $15 shipping fee I wasn't expecting. I just closed the tab."
Account requirement friction
73% of users abandoned when forced to create an account before checkout
Trust and security concerns
Users expressed hesitation about payment security with no visible trust badges or SSL indicators
How Might We Statements
• How might we make costs transparent from the start?
• How might we reduce friction for first-time buyers?
• How might we build trust during the payment process?
Approach and Strategy
North Star Metric
Checkout completion rate
We focused on the percentage of users who start checkout and successfully complete their purchase
Design Principles
1
Transparency: Show all costs upfront
2
Simplicity: Remove unnecessary steps
3
Trust: Reinforce security at key moments
Key Hypotheses
• Guest checkout will increase conversions by 15%+
• Showing shipping costs earlier will reduce abandonment
• Progress indicators will increase completion rates
Design Process and Iterations
Wireframes Evolution
Before: Multi-step Form
4 separate pages with unclear progress
• Forced account creation
• Shipping cost revealed at final step
• No save progress option
After: Single-page Checkout
All info on one scrollable page with live preview
• Guest checkout default
• Live shipping calculation
• Auto-save in progress
Key Design Decisions
✓
Single-page checkout over multi-step
Testing showed users preferred seeing all fields at once with a progress bar, reducing cognitive load from navigating between pages
✓
Live shipping calculator in sidebar
Real-time cost updates as users enter their zip code eliminated surprise fees at the end
✓
Guest checkout as default with optional account creation
Moved account creation to post-purchase, with benefits highlighted to encourage sign-ups without blocking purchase

Learnings and Next Steps
What Worked Well
✓
Early and continuous user testing caught major issues before development started
✓
Close collaboration with engineering prevented scope creep and technical surprises
✓
Guest checkout option had immediate, measurable impact on conversions
What I'd Do Differently
→
Conduct more international user testing—we discovered localization issues post-launch
→
Plan for analytics instrumentation earlier in the design process
Next Steps and Future Enhancements
Test one-click checkout for returning users (in progress)
Explore digital wallet integrations (Apple Pay, Google Pay)
Add saved address autocomplete for faster mobile entry
