Inventory management has become a strategic challenge for companies operating across multiple sales channels, outsourcing their logistics, or working with several warehouses. In this context, having a high-performing Inventory Management System (IMS) is essential to control stock levels, secure the customer promise, and manage costs.
However, logistics organizations have evolved significantly. Inventory is now spread across multiple locations, often managed by third-party logistics providers (3PLs), and handled through heterogeneous systems (ERP, OMS, WMS, e-commerce CMS). The challenge is therefore no longer just choosing an IMS, but ensuring a reliable, shared inventory view across the entire logistics ecosystem.
Spacefill positions itself as a next-generation IMS, designed for multi-warehouse and multi-3PL environments. Spacefill acts as a stock synchronization and visibility layer, capable of connecting IMS modules integrated within broader systems (ERP, OMS) as well as existing WMS platforms, including those used by logistics providers. It enables companies to fully leverage their inventory management, even in outsourced and complex logistics environments.

Spacefill does not replace an IMS—it connects it to operational reality.
There are many powerful IMS solutions on the market, each suited to specific contexts.
But once logistics operations become distributed or outsourced, performance no longer depends on an IMS alone, but on its ability to be connected and synchronized across the entire logistics ecosystem.
This is where Spacefill positions itself as a key complement to IMS platforms, bringing visibility, orchestration, and collaboration where traditional tools reach their limits.
