Building a $10K/Month SaaS with n8n and No-Code Tools

The exact stack and strategy I used to build a profitable SaaS without writing much code.

From Idea to $10K MRR in 6 Months

What's up builders! Lisa here. Last year I was a burned-out developer. Today I run a profitable SaaS that practically runs itself. Here's exactly how I did it with n8n and no-code tools.

The Backstory

I kept seeing the same problem everywhere: Small businesses drowning in customer reviews across 20 different platforms. They'd miss negative reviews for days, losing customers.

My solution? ReviewRadar - an automated review monitoring and response system.

The Tech Stack (Total Cost: $89/month)

Here's what powers a $10K/month business:

• Frontend: Webflow ($29/month)
• Backend Logic: n8n self-hosted on Hetzner ($20/month)
• Database: Supabase ($25/month)
• Payments: Stripe (2.9% + 30¢)
• Email: SendGrid ($15/month)
• Analytics: Plausible (included in Webflow)

That's it. No AWS bills. No DevOps nightmares.

The MVP in 2 Weeks

Week 1:

• Built the landing page in Webflow
• Set up Stripe checkout
• Created the database schema in Supabase

Week 2:

• Built the core n8n workflow (more on this below)
• Connected everything together
• Launched to 10 beta users

The Magic n8n Workflow

This single workflow does EVERYTHING:

1. Monitors Reviews (every 30 minutes):

   • Google Business
   • Yelp
   • Facebook
   • TripAdvisor
   • 15+ other platforms

2. Analyzes Sentiment:

   • Uses OpenAI to determine if positive/negative/neutral
   • Extracts key themes
   • Detects urgent issues

3. Takes Action:

   • Negative review? Instant SMS + email to owner
   • Drafts a response template
   • Creates a task in their system
   • Updates analytics dashboard

4. Learns and Improves:

   • Tracks which responses work best
   • Suggests improvements
   • Monthly reports on review trends

Getting the First 100 Customers

No fancy growth hacks. Just:

1. Local Facebook Groups: "Hey, I built this tool for local businesses..."
2. Cold Email: 10 personalized emails per day to restaurants
3. Free Trial: 14 days, no credit card
4. Case Studies: Showed how Customer #1 saved a $2K/month client

Month 1: 8 customers Month 3: 47 customers
Month 6: 127 customers at $79/month average

The Numbers That Matter

• Customer Acquisition Cost: $23
• Lifetime Value: $1,847
• Churn: 3.2% monthly
• Profit Margin: 91% (yeah, really)
• Time Spent: 10 hours/week

Lessons Learned

1. Start embarrassingly simple My first version only monitored Google reviews. That's it. But it solved a real problem.

2. Let n8n do the heavy lifting I could've coded all this. But why? n8n handles the complex stuff while I focus on customers.

3. Charge more than you think I started at $29/month. Customers said "that's it?" Now it's $79-199/month.

4. Support is your moat Competitors can copy features. They can't copy giving a damn about customers.

What's Next?

We just hit $12K MRR and hired our first support person. The goal? $50K MRR by year-end without writing more code.

New features coming:

• AI that learns each business's "voice"
• Competitive review analysis
• Integration with POS systems

Your Turn

Stop overthinking. That idea you have? Someone needs it. Here's your playbook:

1. Find a painful, specific problem
2. Build the simplest solution possible
3. Charge money from day 1
4. Use n8n to automate everything
5. Talk to customers constantly

The tools exist. The playbook is proven. What's stopping you?

Question for you: What's the ONE manual task businesses do that drives them crazy? That's your SaaS idea. Build it this weekend.
