Case Study: Tennant achieves 98.5% service levels and 80% efficiency improvement with Slimstock's Slim4

Greater insight enables Tennant to achieve huge efficiency improvements

Tennant, a global manufacturer of cleaning machines that handles 50–60k active SKUs (over 22k in stock), faced a labour‑intensive, specialist‑dependent inventory and forecasting process in its Dutch distribution centre. To tackle this complexity and improve service to EMEA distributors, Tennant engaged Slimstock and adopted its inventory optimisation software, Slim4.

Slimstock’s Slim4 standardized processes and automated forecasting, improving long‑tail management and raising service levels from 96.5% to a stable 98.5%. The solution cut manual workload by about 80% (a task that once took one person two weeks can now be done by four people in one afternoon), reduced back orders and partial shipments, and delivered up to 30% more accurate forecasts, prompting Tennant to expand Slim4 across the business.
