Org-first SaaS boilerplate for serious multi-tenant B2B

Org model done right, docs thin

I've hand-rolled org/membership/role tables twice now and both times the invite flow ate a weekend, so the fact that orgs, personal accounts and role-scoped billing are wired up and actually covered by tests is the part that sold me. Better Auth as the base is a solid pick over rolling custom sessions, and having three deploy targets configured means I didn't spend the first day fighting Vercel vs. a VPS. $200 one-time is fair for what you get, but go in knowing it's a Next.js 16 App Router codebase with Prisma baked in, so if you're on an older Next version or prefer Drizzle you'll be ripping out plumbing for a while. The docs cover the happy path but got thin when I wanted to understand how org-level subscriptions interact with seat changes mid-cycle, and I ended up reading the webhook handlers directly to figure it out. Would also like clearer guidance on what's safe to customize vs. what's load-bearing for the auth flows, because the repo is big enough that it's not obvious. Still,
