Ecommerce UI design

Interface redesign for a wholesale and retail supermarket in Paraguay.

Fortis serves two audiences that rarely share the same priorities: everyday shoppers filling a weekly cart, and wholesale buyers managing inventory at scale. The real challenge was building one interface that doesn't compromise either.

Friction Mapping

The existing product was hard to read at a glance. Navigation was slow, pricing was ambiguous, and the product structure didn't reflect how people actually shop, whether they're buying one unit or a hundred.

Pricing Architecture

The redesign started with the one decision that mattered most: how prices are shown. The distinction between unit pricing and wholesale pricing isn't a detail. It's the core of how Fortis users make purchasing decisions, and getting that right shaped everything else.

Decision Support

Two tools were introduced to support real purchasing behavior. A comparison feature to evaluate products side by side. A drink calculator to translate vague event needs into concrete quantities. Both built around how bulk buyers actually think, not how interfaces typically assume they do.
