Implementation Guide

How to implement MVP Development in SaaS — step by step

01

Scope Day (Day 0)

  • Write a one-sentence problem statement: '[User type] who [problem] wants [solution] so they can [outcome]'
  • List every possible feature — then cut everything that isn't required for the core value prop
  • Draw the data model (entities, relationships) before writing any code
  • Define your definition of done: what does 'shipped' actually mean?
02

Build Sprint (Days 1–4)

  • Set up Next.js + Supabase + Tailwind + Vercel in Day 1
  • Build auth and core data models before any UI polish
  • Use AI coding assistance for boilerplate, tests, and repetitive logic
  • Ship to a staging URL every day — never code without deploying
03

Production Audit (Day 5)

  • Check all auth flows: signup, login, password reset, session expiry
  • Validate all user inputs — never trust client-side data
  • Add rate limiting to all API routes
  • Test database queries under realistic load
  • Verify environment variables are not exposed to the client
