Case Study: Aer-Wsale reduces stockouts and stabilizes service levels with Intuendi

Balancing Service Levels in an Extremely Demanding Market

Aer-Wsale, a Croatian wholesaler and dropshipper of e-cigarettes and liquids, faced constant pressure to maintain high service levels in a volatile, high-turnover B2B market. Late detection of demand spikes was leading to stockouts on high-velocity SKUs, lower fill rates, and lost revenue. To address this, the company turned to Intuendi’s demand planning and forecasting platform for a more predictive approach.

With Intuendi, Aer-Wsale used forecasting models that monitored consumption signals early and automatically adjusted replenishment recommendations within daily planning workflows. The team adopted the system’s guidance with 80% adherence, helping stabilize service levels despite demand volatility. The results included a 10% reduction in stockout rate in 2025 versus 2024, stronger protection of fast-moving SKUs, and a planning process that anticipated demand instead of reacting late.
