Enterprise-ready playbook

Ship RBAC and custom roles

Updated 2026-07-19

Why enterprises demand it

  • Access must be least-privilege and mapped to the customer's own structure
  • Larger customers demand custom roles, not just admin/member
  • Auditors expect role definitions and periodic access reviews

How to implement

  1. 1Scope roles and permissions to the Organization
  2. 2Ship sensible default roles, then allow custom roles
  3. 3Externalize authorization decisions from scattered app code
  4. 4Plan a path to fine-grained / relationship-based authorization for resource-level access

Standards

  • RBAC
  • ABAC / ReBAC for fine-grained needs
  • OAuth 2.1 scopes

Pitfalls

Global roles ignoring tenancy

Roles must be per-organization or you cannot isolate customers.

Authorization scattered in code

It becomes untestable and unauditable; centralize it.

Fixed roles only

Enterprises need custom roles; a rigid set blocks deals.

Build checklist

  • Org-scoped roles and permissions
  • Default roles plus custom roles
  • Centralized authorization decisions
  • A planned path to fine-grained authorization

What to require of a platform

  • Org-scoped RBAC with custom roles
  • Fine-grained / relationship-based authorization option
  • Centralized policy

FAQ

When do I need fine-grained authorization instead of RBAC?
When access depends on relationships to specific resources (this user can edit these documents) rather than broad roles. Start with clean org-scoped RBAC and move to relationship-based (ReBAC) authorization as resource-level needs grow.
Do enterprises expect custom roles?
Larger customers usually do. A fixed admin/member set blocks deals; enterprises want to define roles that map to their own structure, scoped to their organization.
