✅ Step 1: The Idea + Tech Stack

I wanted to create a simple task management tool for freelancers and small teams. 💡 The goal was to:

Create and assign tasks
Use Firebase for real-time collaboration
Have a sleek, modern UI with TailwindCSS

💻 Tech Stack:

Frontend: Angular + TailwindCSS
Backend: Firebase (Firestore DB)
Authentication: Firebase Auth
Hosting: Vercel
Payments: Razorpay (₹10K revenue)

✅ Step 2: Building the SaaS MVP

🔥 1. User Authentication (Firebase Auth)

I added Google Sign-In and email authentication.

🔥 This allowed easy onboarding with a single click.

🚀 2. Real-time Task Management (Firestore)

I used Firestore to store and sync tasks in real-time.

✅ This allowed instant task updates across all devices.

🎯 3. Styling with TailwindCSS

Tailwind made the UI look clean and modern.

🔥 With just a few Tailwind classes, I had a beautiful, responsive UI.

✅ Step 3: Deployment & Hosting

I deployed the SaaS on Vercel with a single command:

✅ Vercel's free tier handled the initial traffic smoothly.

✅ Step 4: Monetizing the SaaS (₹10K Revenue)

I added Razorpay for payments:

🔥 I offered:

Free tier: For basic task management
Pro plan (₹499/month): For advanced features

Within the first month, 20 users upgraded to Pro → ₹10K revenue 💰

✅ Lessons Learned:

Keep the MVP simple: Focus on solving one problem effectively
Firebase + Vercel → Fast, free, and scalable
Monetize early: Even a simple SaaS can generate revenue

🎯 Conclusion:

Building a SaaS with Angular, Firebase, and Tailwind was easier than I expected. By keeping it simple and launching quickly, I was able to validate the idea and make ₹10K in revenue.

🔥 Thinking of building your own SaaS? Start small, iterate fast, and you’ll be surprised how quickly you can earn revenue. 💰
