KontraktorOS overview
What is KontraktorOS?
KontraktorOS is a cloud-based ERP platform built for contractors and construction companies operating in the Indonesian market. The platform consolidates core contractor workflows into a single system, covering bill of quantities (RAB) management, project procurement, warehouse and inventory management, and end-to-end construction project operations management.
By centralizing these functions within one ERP environment, KontraktorOS reduces the operational overhead of managing disconnected tools across budgeting, procurement, and logistics. Project teams gain visibility into cost planning through RAB management, while procurement and warehouse modules coordinate material sourcing and stock control in alignment with active project demands.
The platform targets contractors and construction firms that require structured, integrated oversight of project financials and supply chain activity. As a web-based application delivered under a SaaS model, KontraktorOS is accessible without on-premise infrastructure, supporting deployment across project sites and office locations within Indonesia's construction sector.
