Launch Your SaaS in 14 Days: Step by Step with Next.js

Launching a SaaS can feel like running a marathon without a map. You know the finish line exists, but every step seems uncertain. Should you build the dashboard first? Or set up authentication? How do you handle payments?

With Zero to SaaS, you can finish the journey in just 14 days. Here's how developers, indie hackers, and aspiring founders structure their launch.

Day 1-3: Set Up Your Foundations

Start by creating your Next.js project and configuring Tailwind + DaisyUI for fast UI design. These first days are about:

• Folder structure and project setup
• Environment variables and configuration
• Installing dependencies
• Planning your database models

The goal is a stable base, so the next steps build on solid ground.

Day 4-6: Authentication and User Management

Authentication is the backbone of any SaaS. Focus on:

• Email signup and login
• Google OAuth integration
• Secure password storage
• Route protection

By the end of day 6, you should have a fully working user system, ready to handle real signups.

Day 7-9: Database and Core Features

Now, implement your MongoDB models and API routes. Add your first core features. Typical tasks:

• Create collections for users, subscriptions, and data
• Build APIs to read/write user data
• Test endpoints with Postman or Insomnia
• Integrate feature logic into your dashboard

Focus on one core feature to ensure a usable MVP by day 9.

Day 10-12: Payments and Subscription Logic

Stripe integration can intimidate many developers. Zero to SaaS teaches it step by step:

• Set up Stripe checkout
• Create subscription plans
• Implement webhooks to track payments
• Connect billing to user accounts

By day 12, your app can securely handle paying users.

Day 13: UI Polish and Testing

Take a day to:

• Improve UI with Tailwind + DaisyUI
• Test workflows
• Validate forms and error handling
• Run end-to-end tests

This ensures your MVP feels professional and works smoothly.

Day 14: Deploy Live

Finally, deploy on Vercel:

• Configure environment variables
• Deploy backend and frontend together
• Test production features
• Celebrate your live SaaS
