// How to build Real-Time SaaS Platform with Admin & Third-Party Integrations
Supabase gives you auth, PostgreSQL, and realtime out of the box — dramatically reducing build time for a solo or no-team scenario. Next.js on Vercel eliminates DevOps overhead. This stack is opinionated and fast to ship, which matches your ASAP timeline and seed-stage budget, while being scalable enough for micro user scale without over-engineering.

Typical SaaS projects cost $1,800–$5,000 USD and take 6–8 weeks with an Indian dev team. See the full cost guide →

## What to build in the MVP
-User authentication (signup, login, password reset, OAuth via Google)
-Role-based access control (admin vs end-user roles)
-Admin dashboard: user management, basic analytics, and content/config controls
-Realtime data feed or notifications (Supabase Realtime subscriptions on key tables)
-At least 1 third-party integration via API/webhook (e.g. Slack, Stripe, or Zapier webhook endpoint)
-Tenant/account scoping for SaaS multi-user context
-Transactional email notifications (account events, alerts)
-Basic settings and profile management per user

## Engineering risks to plan for
!No team + ASAP timeline is the highest risk: realtime + integrations + admin together require at least 1 full-stack developer fully dedicated — plan to hire a freelancer or agency immediately or timeline will slip.
!Scope creep risk is high: auth + admin + integrations + realtime is 4 distinct complexity layers — without strict MVP discipline, this easily becomes a 5–6 month build.
!Integration ambiguity: 'integrations' is undefined — each third-party API (Stripe, Slack, CRMs, etc.) adds 3–7 days of dev time; the cost range assumes only 1 integration at MVP.
!Seed budget may be tight: if budget is under ₹5L / $6K, you will need to cut either realtime or integrations from v1 — both together push toward the higher end of the range.
!Realtime at scale needs architectural care: Supabase Realtime is sufficient for micro scale, but if user count grows quickly, connection limits on free/pro tier can become a bottleneck requiring migration.
