TrellisOS

The Structured Support

TrellisOS Overview

TrellisOS is the infrastructure layer for ministry operations—built to keep stewardship, compliance, and growth aligned without sacrificing clarity. The trellis provides structure so the mission can climb.

Meet the personas

Mission

Bring order to the complexity of mission so leaders can focus on people, not spreadsheets.

Automate, Liberate, Amplify

Operating Principles

  • Order over chaos: every workflow has a trusted audit trail.
  • Policy-first: OPA enforces the guardrails before money moves.
  • Multi-tenant by design: RLS protects every organization.

Integrity Layer

TrellisOS keeps the financial core immutable, event-driven, and audit-ready—so stewardship remains defensible under scrutiny.

Payments & Giving

Mocked Stripe checkout plus ledger posting.

Compliance Receipts

Automated receipts with delivery queueing.

KYC Onboarding

Verification workflows with approval gates.
