How I Built My First SaaS App for $10: A Weekend Builder’s Journey

4 min readJun 21, 2025

1. The Real Problem I Saw (Idea behind MokshaMetrics)

Over one weekend, I noticed friends, who are freelancers, solo consultants and part-time professionals, managing client info across spreadsheets, calendars, email, and chat apps. One missed a follow-up and lost a client; another accidentally sent invoices twice. That sparked a mission: centralize leads, automate follow-ups, and streamline invoicing — all on a shoestring budget.

2. Setting the Weekend Challenge

Goal: Build a functional MVP in just 48 hours, with only a domain purchase (~$10) as budget. No paid hosting, no complex setup.

Tech stack:

Frontend: React
Backend: Node.js + Supabase for auth, database, and storage
Hosting: Netlify (free tier)

3. Day 1: Planning, Schemas & Authentication

Mapped core workflows: lead capture, email scheduling, invoice creation, and calendar sync
Drew quick UI sketches: dashboard, lead-detail view, invoice modal
Set up Supabase schema
Implemented social/email-based signup and a blank user dashboard by evening

4. Day 2: Core Features + Integrations

Lead management: Create, edit, delete, add notes
Email scheduler: Pick follow-up times → Node server schedules → Supabase triggers via SendGrid
Invoice builder: Select lead → Add items → Generate PDF with jsPDF → Send via dashboard
Calendar sync: OAuth integration with Google Calendar to add events directly

By evening, every feature worked — just needed fine-tuning.

5. Day 3: Polish, Responsive UI & Launch Prep

UI cleanup: Custom React components, mobile-first responsiveness, refined color palette
UX polish: Loader indicators, toast notifications
Screenshot: Captured a high-res dashboard showing “Send Invoice” & “Schedule Email” buttons for visual clarity
Beta testing: 3 friends tested the complete flow; UX bugs were logged and fixed
Deployment: Launched live via Netlify and shared the URL with 10 users

Initial reactions:

“Super fast and intuitive — did more in 10 minutes than my old system in 2 days.”
“This is exactly what I needed.”
