Paybill builds foundational platforms for modern SaaS systems and safe AI-driven applications.
We focus on control, predictability, and security — enabling platforms and AI agents to operate within clearly defined boundaries rather than uncontrolled automation.
Our work is centered around two core systems:
Paybill Control Plane
A cloud-agnostic, multi-tenant control plane designed to simplify tenant onboarding, subscription management, billing-aware provisioning, and tenant lifecycle orchestration. It supports multiple isolation strategies — Silo, Pooled, and Bridge — allowing SaaS platforms to evolve their architecture as they scale.
The control plane integrates deeply with Terraform, databases, and major cloud providers including AWS, Azure, Google Cloud, Oracle Cloud, and IBM Cloud. Infrastructure is deterministic, auditable, and subscription-aware by design.
Paybill Framework
A TypeScript framework that gives AI agents the ability to act safely and reliably within production systems. Instead of free-form agents, Paybill enforces controlled workflows, explicit access management (ACL), schema-driven database operations, and predictable execution paths.
Paybill enables teams to use AI where it matters — without sacrificing security, data integrity, or operational clarity.
Our principles • Constraints over freedom
• Workflows over prompts
• Schemas over assumptions
• Security by design
• Predictability at scale
Paybill is open-source and built for platform engineers, SaaS architects, and teams building systems that must scale responsibly.
Control the platform. Constrain the agent. Scale with confidence.
