Context
SwiftCart, a D2C electronics marketplace processing $2M/month in GMV, was losing customers at checkout. Their 5-step flow had a 72% abandonment rate — well above the industry average of 55%.
Constraint
We couldn't replace the existing backend; the new checkout had to sit on top of their legacy API layer. And the A/B test framework needed to run both flows simultaneously without impacting page speed.
What We Built
A single-page checkout with progressive disclosure, address autocomplete, saved payment methods, and real-time shipping estimates. We built a lightweight A/B testing harness that split traffic at the edge using Vercel middleware.
“We'd been debating our checkout for months. GoInfoo came in, ran the research, and shipped a measurably better version in six weeks. The ROI was immediate.”
