Case Study: De Mandemakers Groep achieves 100% fulfilment and 20% inventory reduction with Slimstock

Slim4 Platform Helps Mandemakers Achieve a 100% Fulfilment Rate for the First Time in Its History

De Mandemakers Groep, the kitchen, bathroom and furniture specialist behind brands like Piet Klerkx and Brugman Keukens & Badkamers, needed better control over rapidly growing inventory across multiple sales channels. As demand became more unpredictable and planners were still relying on Excel, the company faced labour-intensive ordering, higher risk of stockouts, and pressure to maintain strong service levels. Slimstock was brought in to help with inventory planning using the Slim4 platform.

Slimstock implemented Slim4, giving De Mandemakers Groep centralized data, exception-based alerts, and more robust ordering recommendations. The rollout was completed smoothly, and the planning team quickly adopted the system. As a result, De Mandemakers Groep reduced inventory by 20% while maintaining—and even improving—service levels, including achieving a 100% fulfilment rate for a full week for the first time in its history.
