## What it does

This skill outlines Twilio governance across three layers: Organization, Account, and Subaccount. It defines when to keep programmatic subaccounts under consolidated invoicing and when to create managed accounts with separate billing (limited to 10 by default). It also codifies permissions for the single Owner role alongside Administrator and Standard users.

Guidance includes corporate domain verification rules (Restricted, Auto-enrollment, Blocked), identity provider SSO setups, and automated lifecycle management via SCIM 2.0. It also specifies how a Prime organization absorbs a Candidate during a merge and how HIPAA compliance flags apply per account after executing a BAA.

A single user profile can belong to only one Organization at a time, and generic email domains such as `gmail.com` cannot be registered as verified domains.

## When to use it
- structure multi-team environments using Owner, Admin, and Standard roles
- enforce SSO and automated user provisioning via SCIM 2.0
- decide between independent organization accounts and subaccount pools
- merge separate Twilio Organizations under verified corporate domains
- apply HIPAA compliance flags to individual managed accounts

## Example prompts
- Help me configure SSO and domain auto-enrollment in Twilio Organizations.
- What are the requirements to merge a Candidate organization into our Prime org?
- Compare Twilio Organizations and subaccounts for our multi-tenant billing architecture.

  Set up and manage Twilio Organizations for centralized account and user
  governance. Covers the Organization > Account > Subaccount hierarchy,

## Overview

Every Twilio customer automatically gets an Organization when they sign up (auto-created since May 2024 for new signups; since June 2024 for existing paying customers). An Organization is the top-level container that groups accounts, users, and security policies. The creation has no effect on existing account functionality. Most developers never need to touch it — but as soon as you have multiple accounts, teams, or compliance requirements (SSO, HIPAA), Organization setup becomes essential.

**Hierarchy:** Organization > Accounts > Subaccounts

| Layer | What it is | When you need it |
|-------|-----------|-----------------|
| **Organization** | Centralized governance: users, accounts, domains, SSO | Multiple teams or accounts, SSO, HIPAA designation |
| **Account** | Application boundary: all Twilio products, resources, billing live here | Always — you need at least one |
| **Subaccount** | Isolated partition under an account: separate resources, consolidated billing | Multi-tenant apps, per-customer isolation |

---

## Organization vs Subaccount — When to Use Which

| Dimension | Organization (Managed Accounts) | Subaccounts |
|-----------|----------------------------------|-------------|
| **Management** | Console UI + Organizations API | REST API (`/2010-04-01/Accounts`) |
| **Billing** | Independent per account | Consolidated to parent account |
| **Account limit** | 10 per Organization (default) | 1 per unupgraded account; 1,000 per upgraded account (contact AE for more) |
| **User management** | Full lifecycle: invite, roles, SSO, SCIM | None — no user concept |
| **SSO/SCIM** | Supported | Not applicable |
| **HIPAA designation** | Per-account toggle in Admin console | Inherits from parent (new only) |
| **Resource isolation** | Separate accounts, separate credentials | Separate but parent can access all |
| **Cost** | Free | Free |

**Rule of thumb:** Use **Organizations** when different teams/users need separate billing and access control. Use **Subaccounts** when your application needs programmatic multi-tenant isolation with consolidated billing.

## Organization Roles

| Role | Capabilities | Limit |
|------|-------------|-------|
| **Owner** | Full control + sole authority to delete the Organization | 1 per Organization |
| **Administrator** | Invite/remove users, add/create accounts, modify settings | Unlimited |
| **Standard User** | Access only to specified accounts — no org management | Unlimited (default) |
