How a leading dairy brand reduced stockouts and drove $2.3mm in incremental sales at Walmart
By using real-time insights to fix inventory gaps, the brand increased availability and achieved 5.5x ROI.
The Challenge
A national dairy brand was struggling to maintain in-stock availability of its top 10 SKUs at Walmart — especially during promotional periods.
One price-driven promotion — a $0.33 reduction on a top-selling 96oz SKU — drove unexpected demand surges. But without the right systems in place to respond, the product frequently stocked out. This created a poorer customer experience, which generated shopper frustration and lost sales, threatening the success of the campaign and long-term brand image.
To turn the tide on the product and buying behavior, the brand needed a solution that would surface out-of-stock trends in real time and enable fast, targeted remediation.
The Trax Solution
Trax deployed a Signal-Based Merchandising (SBM) program tailored to address the brand’s most critical in-store execution gaps.
The approach included:
• Surfacing real-time OOS alerts across key Walmart locations
to keep merchandise displays fully stocked
• Deploying Trax field reps to act on insights quickly, improving shelf conditions such as store displays
• Informing backroom inventory adjustments to better support high-volume SKUs
• Driving compliance with shelf standards to support sales consistency
The data-driven actions helped the brand not only resolve short-term OOS issues — but implement longer-term changes to prevent them in the future and improve its ability to address customer needs.
The Results
The SBM program delivered strong, measurable improvements across availability and sales performance:
