Template

What This Template Offers

A best-practice ER diagram for multi-tenant SaaS that maps users, teams, memberships, and billing so you can design, review, and ship with confidence.

Multi-tenant User–Team pattern
One subscription per team constraint
Composite key for team_memberships
Clear PK/UK/FK notation and cardinality
Stripe-ready fields (status, subscription_id)

Use cases

Perfect Use Cases

Kickstart a new SaaS data model

Start from a proven User–Team–Subscription structure instead of a blank page. Reduce ambiguity and align backend, product, and analytics early.

Stripe billing or plan migration

Validate one-subscription-per-team, unique stripe_subscription_id, and status lifecycle (active, past_due, canceled) before you touch production.

RBAC and collaboration design

Model roles per team via team_memberships with a composite key. Make admin/member permissions explicit and auditable.

Engineering onboarding & docs

Hand new teammates a clear, professional ER diagram that explains ownership, joins, and constraints at a glance.

Customize

Keep role values controlled (ENUM or validated list) to prevent permission drift
