Standard engagement
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.

What ships during the engagement.
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
What you walk away with.
- Auth: email + password, magic link, OAuth (Google/GitHub/etc.)
- Multi-tenant orgs with role-based access
- Stripe subscriptions + Customer Portal
“They scoped, shipped, and operated our RAG pipeline in twelve days. Citation accuracy on our eval set landed at 92%, and ongoing tuning costs us less than a Slack seat.”
- Which 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.
- Do 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.
