Open Source · Apache 2.0
The Open Operating System for Procurement AI
OpenS2P is a free, open-source Source-to-Pay platform built API-first, event-driven, and AI-native from day one — so any organization, anywhere, can run modern procurement without vendor lock-in.
Our Mission
Enterprise procurement remains one of the least automated, most fragmented areas of business operations. Organizations spend 70–85% of their procurement cycles on low-value data entry, status chasing, and manual exception handling. OpenS2P exists to change that — a vendor-neutral, API-first, AI-augmented procurement platform, built in the open, for everyone.

Architecture Principles
Cloud Native
Kubernetes-first, containerized, no bare-metal lock-in.
AI Native
Agents, confidence scoring, and human-in-the-loop gates are first-class, not bolted on.
API First
Every capability is an API before it's a UI.
Event Driven
Domain boundaries crossed only via typed, versioned events.
Enterprise Secure
Zero-trust posture, policy-as-code, PII-safe AI pipelines.
Vendor Neutral
Swap cloud, LLM, or ERP providers — no strategic lock-in.
Open Source Friendly
Apache 2.0, public ADRs, and a low barrier to contribute.
