Undisclosed International Multi-Brand Manufacturer of Air Distribution Products

Large-footprint European retailers face a compounding challenge: as store counts grow across geographies, manual inventory systems become structurally inadequate. This retailer operated 980 stores across 23 countries, managing a highly seasonal product category — footwear — where size-run completeness and style availability directly drive conversion. Existing tools could not accommodate the operational complexity of cross-border logistics, varied sorter capacities, and shipment constraints at that scale. Planners relied on labor-intensive manual processes to make replenishment and transfer decisions, creating persistent gaps in on-shelf availability. The result was chronic lost sales and inefficient use of distribution center capacity — a systemic drag on both revenue and workforce productivity.

The retailer partnered with invent.ai to deploy two purpose-built AI modules: Store Replenishment and Transfer Optimization. The Store Replenishment solution uses machine learning to generate real-time replenishment orders, matching product quantities and locations to actual demand signals rather than static par levels. The Transfer Optimization module applies predictive analytics to identify imbalanced inventory across the network and recommends inter-store movements that capture demand while minimizing excess stock accumulation. Both solutions were customized to the retailer's specific operational constraints — including sorter throughput limits, shipment windows, and package prioritization rules — which off-the-shelf tools had previously been unable to accommodate. The full deployment across all 980 stores spanned six months, integrating with existing warehouse and store systems to automate decision flows that had previously required manual planner intervention.

The deployment produced measurable improvements across availability, revenue, and operational efficiency within the first measurement period:

• Significant additional sales revenue generated through improved product availability and optimized inter-store transfers
• A meaningful reduction in lost sales, reflecting direct gains from closing availability gaps across the network
• A notable improvement in on-shelf availability, ensuring customers encountered in-stock product more consistently
• 4% increase in the additional sales representative unit ratio, attributable to smarter transfer decisions routing units to highest-demand locations

Beyond the headline numbers, automated decision-making freed planners from manual replenishment calculations, redirecting workforce capacity toward higher-value analysis and exception management.

• Replenishment and transfer optimization compound when deployed together — availability gains reduce lost sales, while demand-driven transfers capture revenue that static distribution would have missed.
• At enterprise scale (900+ stores, multiple countries), AI solutions must be configured around operational constraints like sorter capacity and shipment windows — generic tools will underperform.
• A six-month full-network deployment is achievable when the vendor builds to the retailer's specific operational model rather than requiring process changes to fit a standard product.
• Tracking lost sales reduction and on-shelf availability as separate KPIs provides clearer attribution of where AI is generating value versus where further tuning is needed.
