Sainsbury’s Merchandising App

Sainsbury’s Tu Clothing was facing a significant stock availability challenge, with customers unable to find the items they wanted 50 percent of the time. This was directly impacting customer satisfaction and limiting growth. Newton led the development of two new software tools to support over 100 merchandisers across all clothing categories, enabling more accurate stock decisions by moving away from unreliable sales data toward a more insight led approach.

I led the UX partnership between Magnetic and Newton to ensure these tools were not only technically robust, but genuinely usable and adopted in day to day workflows. My role focused on translating complex merchandising logic into intuitive digital experiences that merchandisers could trust and act on with confidence.

I developed a cohesive design system aligned to both Sainsbury’s brand and Newton’s wider software suite, creating consistency across tools and establishing clearer visual standards. Beyond a visual reskin, I drove targeted UX improvements grounded in real user behaviour. This included simplifying layouts, clarifying content hierarchy, and restructuring navigation to reduce cognitive load and speed up decision making.

The result was a set of intuitive, insight driven tools that empowered merchandisers to make faster, more confident stock decisions, helping Tu deliver the right products, in the right sizes, at the right time, and supporting wider goals around availability, customer satisfaction and growth.
