Design Audit Case Study: Reworking Checkout for a DTC Startup

Design · 6 min read

Shopora, a DTC apparel brand, saw heavy mobile traffic but poor checkout conversion. The design team ran a heuristic audit, session recordings, and five rapid usability tests. They found product pages overloaded with upsell carousels, unclear size guidance, and a cart modal that hid shipping costs until late in the flow—three product-design decisions that caused hesitation.

Instead of a full visual overhaul, the team implemented priority changes: consolidate upsells below the fold, add an inline size assistant with concise guidance and a single-callout exception pattern, and move shipping transparency to the product page and cart summary. A “checkout with saved info” quick path was also added for returning users.

A 28-day experiment showed an 18% lift in mobile conversion and a 12% decrease in cart abandonment. Heatmaps revealed more consistent CTA engagement and fewer back-and-forth navigations between product and cart. Customer support tickets about sizing dropped sharply, suggesting the size assistant also cut post-purchase friction.

The case highlights how audits that tie design heuristics to user behavior yield practical, testable product decisions. Prioritizing clarity over feature density was the central theme—and it paid off in measurable revenue gains.
