Case Study: How Payflux Cut Checkout Friction and Boosted Conversion 18%

Design · 5 min read

Payflux ran a three-month initiative to rework its merchant checkout experience after analytics showed a 33% drop-off at the payment selection step. The design team started with a heuristic audit and five unmoderated sessions, which revealed users were confused by the mixed order of payment methods, unexpected fees, and redundant confirmation fields.

Design changes included reordering payment options based on user intent signals, surfacing price transparency badges, and consolidating confirmation steps into an inline summary. Crucially, the team implemented a single-row payment selector that emphasized default choices and offered a clear path to edit details without leaving the screen.

A randomized A/B test across 50,000 checkouts delivered an 18% lift in completed transactions and a 26% reduction in customer support tickets about billing. Post-launch telemetry also showed higher repeat purchase rates and a small uptick in average order value, validating that reducing cognitive load at checkout improves both UX and revenue.
