Overview
Slimstock develops Slim4, a supply chain planning platform that handles demand forecasting, inventory optimization, replenishment, and sales & operations planning (S&OP). Founded in 1993 in the Netherlands, the company positions Slim4 as a planning layer that connects to a company's existing ERP rather than replacing it, pulling transactional and master data from the ERP and feeding back recommended forecasts, order proposals, and stock targets. The platform is used by more than 1,700 organizations across wholesale, retail, and manufacturing.
The product is organized around several planning domains. Demand management covers statistical and machine-learning forecasting, demand sensing, and seasonality/promotion modeling across daily-to-annual horizons. Inventory management covers stock optimization, automatic replenishment, multi-echelon inventory optimization (MEIO), network balancing, and shelf-life handling for fresh goods. Supply chain planning adds supply and production planning, scenario planning, integrated business planning (IBP), and S&OP/S&OE workflows. A control-tower dashboard surfaces KPIs, exceptions, and workflow status in one view.
Slim4 is offered as a cloud-native platform, with on-premise and fully hosted options also available according to vendor and review-site descriptions. Implementation is consultant-led, and Slimstock pairs the software with its own supply chain consultants and training. The platform integrates with major ERP systems including SAP, Microsoft Dynamics, Oracle, NetSuite, and Salesforce; a published Slim4 connector exists for Microsoft Dynamics 365 Business Central. Pricing is quote-based and not publicly listed.
