Multi-tenant model
Tenant isolation patterns and membership so orgs stay separated from day one.
Stripe billing
Plans, checkout, customer portal hooks, and webhook handling for subscriptions.
Auth ready
Sign-up, login, sessions/tokens, and role checks you can extend for SSO later.
Teams and invites
Invite flows and basic org management so customers are not stuck as solo users.
API surface
REST endpoints and a clear place to hang your domain features.
Postgres schema
Migrations and a sensible starting schema instead of a greenfield scramble.
Stack
Modern defaults you can keep or swap as you grow
Next.js
App Router, TypeScript, Tailwind

Auth middleware, Stripe webhooks
