The SaaS MVP Checklist: What to Build (and What to Skip)
The biggest mistake founders make isn't building the wrong thing — it's building too much of the right thing. An MVP that takes 12 months to ship isn't a minimum viable product. It's just a late product.
Here's how to scope your MVP correctly and ship in 4–8 weeks. If you haven't validated your idea yet, start there first — read How to Validate Your SaaS Idea before scoping anything.
The MVP Rule
An MVP is the smallest version of your product that delivers the core value proposition to your target user.
Not the smallest version that might succeed. The smallest version that proves whether the core value is real.
What Every SaaS MVP Needs
Core value loop
The one thing your product does that makes someone's life measurably better. One workflow. One outcome. Everything else is secondary.
User authentication
Email/password or magic link. No OAuth integrations in v1 — just make it work.
Basic onboarding
Users need to reach their first "aha moment" without you holding their hand. A 3-step onboarding wizard is enough.
The core feature — nothing else
Build the one thing your product is about. Not five things. One thing, done well.
Billing (if charging from day one)
Stripe integration. Monthly subscription. One plan. That's it.
Basic error handling
Users will hit errors. Log them. Show a helpful message. Don't crash silently.
Email notifications
At minimum: welcome email, password reset. Maybe one transactional email related to the core feature.
What Your MVP Does NOT Need
Team/multi-user features
Build for one user first. Multi-tenancy doubles your complexity.
API or integrations
"It integrates with everything" is a Series B feature. Ship the core.
Mobile app
Unless mobile is the core value, a responsive web app is sufficient for v1.
Admin dashboard
You can manage data directly in your database or with a simple script.
Advanced analytics
Google Analytics + a simple events table in your DB is enough.
Social login (Google, GitHub, etc.)
One auth method works. Add OAuth after you have users asking for it.
White-labeling, custom domains, SSO
Enterprise features belong in your roadmap, not your MVP.
The 4-Week MVP Sprint
Week 1: Foundation - Auth (signup, login, password reset) - Database schema - Basic UI shell (navigation, layouts)
Week 2: Core Feature - Build the one thing your product does - Hardcode what can be hardcoded — optimize later
Week 3: Polish + Billing - Stripe integration - Onboarding flow - Error states and loading states
Week 4: Launch Prep - Landing page (see How to Write a High-Converting SaaS Landing Page) - Basic SEO (title, description, OG tags) - 10 beta invites sent to target users
Prioritization Framework
For every feature request or idea, ask:
- Does it deliver the core value proposition? If no — cut.
- Will the product be unusable without it? If no — defer.
- Are 3+ target users asking for it? If no — defer.
- Can it be faked manually? If yes — fake it first.
The "Fake It" Principle
Many features can be faked for the MVP:
| Real Feature | Fake Version |
|---|---|
| AI recommendation engine | You manually send email recommendations |
| Automated report generation | You generate reports manually and email them |
| Real-time dashboard | Daily email digest |
| API integration | CSV import |
| Chat support widget | Email to your personal inbox |
Faking is not cheating — it's discovering whether anyone wants the feature before you build it.
After Launch: The 30-Day Rule
After your MVP launches, don't add new features for 30 days. Instead: - Talk to every user who signs up - Fix bugs immediately - Improve the onboarding based on where users drop off - Ask churned users why they left
The feature requests that come up in 5+ conversations get built next. Everything else goes on the backlog.
When you're ready to go public, follow the SaaS Launch Checklist to cover every channel and technical requirement before launch day.
