X-Sitter – Your WMS becomes a digital process bridge – “Mini-SAP” for SMEs

API-first, real-time transparency and flexible automation – quickly integrated, instantly scalable

What is X-Sitter?

X-Sitter X-Sitter transforms outdated WMS/ERP landscapes into a modern, API-based platform. You can use X-Sitter either as a middleware layer for rapid integration of your systems or as a standalone, modularly configurable warehouse management system (a "mini-SAP" for SMEs). This harmonizes data flows, automates processes, and provides real-time visibility into inventory and process status.

What problems does X-Sitter solve?

  • Standalone solutions & media breaks: X-Sitter connects systems, tools and devices via a unified API – instead of manual coordination.
  • Lack of transparency: Inventory, orders, returns and status are visible in real time – for team, customers and management.
  • High manual effort: Rule-based automations reduce errors, save time and lower integration costs.
  • Scaling is difficult: New customers, locations, or processes can be rolled out more quickly – without having to rebuild everything.
