Services / build / platform

Auth + Billing Foundation

The boring 2 weeks every SaaS skips and regrets.The full auth + billing layer your app actually needs: signup, login, password reset, magic link, OAuth, multi-tenant orgs with roles, Stripe subscriptions, customer portal, audit log, admin impersonation. Done in 2 weeks instead of the 6 it takes when you build it yourself between feature work.

Where this fits in the services matrix.

Every service page now names the buyer state, the commercial shape, and the next route. That keeps the catalog navigable instead of feeling like disconnected offers.

The offer is a route, not a loose task list.

This diagram gives every service page a concrete operating model: intake, system design, implementation, proof, and handoff.

Auth + Billing Foundation moves from fit check to scoped work, then into build/proof/handoff so the buyer can understand how the engagement actually runs.

01// what you walk away with

The outcome, not just the output.

  • 01Auth: email + password, magic link, OAuth (Google/GitHub/etc.)
  • 02Multi-tenant orgs with role-based access
  • 03Stripe subscriptions + Customer Portal
  • 04Audit log of every sensitive action
  • 05Admin impersonation for support workflows
02// scope

Concrete artifacts you keep — and what we leave out.

Working code, written docs, dashboards your team owns. We also list what this engagement deliberately does not cover, so scope is honest before you click.

// deliverables
  • Auth provider integrated (Clerk / Auth.js / Supabase Auth — your call)
  • Org / workspace model with roles (owner / admin / member / billing-admin)
  • Stripe billing wired to org subscriptions
  • Customer Portal embedded
  • Audit log table + writer for every sensitive action
  • Admin impersonation flow with audit trail
  • Email transactional templates (verification, reset, invite)
  • 30-day Slack support
// not included
  • SAML / SSO for enterprise customers (add-on)
  • SCIM provisioning (add-on)
  • Compliance certifications (use SOC 2 sprint)

04// questions

Common questions.

01Which auth provider is best?
Honest pick depends on stage. Clerk: fastest to ship, costs scale with users. Auth.js: zero per-seat cost, more wiring. Supabase Auth: best if you are already on Supabase. We default to Clerk for B2B SaaS under 10k users.
02Do you build it from scratch?
No. We use battle-tested providers and write only the glue. You get a 2-week build, not a 2-month one.
03What if we already have auth?
We can layer billing + orgs + audit log on top of your existing auth. Scope shrinks to ~1 week.
