Workflow Integration: Complete System in Action

Real-world integration examples showing how all tools work together for launching and running a SaaS business

Complete System in Action

This chapter shows how all the tools work together in real-world scenarios, demonstrating the power of integrated workflows.

Total Cost: $0/month for the complete stack during MVP phase

30-Day SaaS Launch Scenario

Real timeline showing how a solopreneur launches a SaaS product using the complete tech stack.

Week 1: Foundation Setup

Development Environment:

# Initialize project
git init saas-mvp
cd saas-mvp

# Create Next.js app
npx create-next-app@latest . --typescript --tailwind --app

# Setup Supabase
npx supabase init
npx supabase start

# Deploy to Vercel
vercel --prod

Tools Activated:

  • GitHub (version control)
  • Vercel (hosting)
  • Supabase (database + auth)
  • VS Code (development)

Outcome: Live staging environment with database and authentication ready.

Week 2: Core Product Build

Development Workflow:

// Feature branch workflow
git checkout -b feature/user-dashboard

// Build with Cursor AI assistance
// - Design database schema
// - Implement auth flow
// - Create dashboard UI

// Push and deploy preview
git push origin feature/user-dashboard
// Vercel auto-deploys preview URL

Tools Activated:

  • Cursor AI (code generation)
  • Supabase (data modeling)
  • Vercel (preview deployments)
  • PostHog (analytics setup)

Outcome: Working MVP with user authentication and core features.

Week 3: Launch Preparation

Marketing Setup:

## Launch Checklist

1. Landing page (Vercel-hosted Next.js)
2. Email collection (Tally forms → Mailchimp)
3. Social media content (Buffer scheduling)
4. Analytics tracking (PostHog events)
5. Documentation (Notion workspace)

Content Creation:

  • Write launch blog post (Notion → export → deploy)
  • Create social media graphics (Canva)
  • Schedule launch day posts (Buffer)
  • Setup email welcome sequence (Mailchiip free tier)

Tools Activated:

  • Tally (waitlist forms)
  • Mailchimp (email marketing)
  • Buffer (social scheduling)
  • Canva (design assets)
  • Notion (documentation)

Outcome: Complete launch funnel ready to drive signups.

Week 4: Launch & Iterate

Launch Day Workflow:

# 1. Deploy production version
git checkout main
git merge develop
vercel --prod

# 2. Activate monitoring
# - PostHog session recordings ON
# - Sentry error tracking ON
# - Supabase logs monitoring

# 3. Social media blitz
# - Buffer publishes scheduled posts
# - Monitor engagement in real-time
# - Respond to feedback via Gmail

# 4. Data collection
# - Tally forms capture signups
# - Mailchimp sends welcome emails
# - PostHog tracks user behavior

Daily Iteration Cycle:

  1. Check PostHog analytics (user behavior)
  2. Review Sentry errors (fix bugs)
  3. Read user feedback (Gmail + social)
  4. Document learnings (Notion)
  5. Plan next features (GitHub Projects)
  6. Ship improvements (Vercel auto-deploy)

Outcome: Live product with active users and data-driven improvement loop.

Integration Flow Examples

Flow 1: Code to Production

Complete deployment pipeline from code to live site with monitoring.

    A[VS Code/Cursor] --> B[GitHub Push]
    B --> C[Vercel Auto-Deploy]
    C --> D[Supabase Sync]
    D --> E[PostHog Tracking]
    E --> F[Sentry Monitoring]
    F --> G[Live Production]

Step-by-Step:

# 1. Write code in Cursor AI
cursor .

# 2. Commit and push
git add .
git commit -m "feat: add user dashboard"
git push origin main

# 3. Vercel auto-deploys (triggered by push)
# 4. Supabase migrations run automatically
# 5. PostHog tracking activates on new pages
# 6. Sentry monitors for errors

# Result: New feature live in ~2 minutes

Flow 2: User Signup to Engagement

Complete user acquisition and onboarding flow.

    A[Tally Form Submit] --> B[Mailchimp Add Contact]
    B --> C[Welcome Email Sent]

    D --> E[Supabase Auth Signup]
    E --> F[PostHog User Identified]
    F --> G[Dashboard Access]
    G --> H[Usage Data Collection]

Configuration:

// Tally form webhook to Mailchimp
{
  "trigger": "form_submit",
  "action": "add_to_mailchimp",
  "list_id": "welcome_sequence",
  "tags": ["new_user", "mvp_launch"]
}

// Mailchimp automation
{
  "trigger": "list_subscribe",
  "delay": "immediate",
  "email": "welcome_template",
  "next_email": "+2 days"
}

// PostHog user identification
posthog.identify(user.id, {
  email: user.email,
  signup_date: new Date(),
  source: 'tally_form'
});

Flow 3: Content to Distribution

Complete content creation and marketing workflow.

    C --> D[Vercel Deploys Blog]
    D --> E[Share via Buffer]
    E --> F[Track in PostHog]
    F --> G[Analyze Engagement]

Workflow:

## Content Pipeline

1. **Draft**: Write blog post in Notion
2. **Review**: Share Notion page for feedback
3. **Export**: Download as Markdown
4. **Deploy**:
   - Add to `content/blog/`
   - Git push triggers Vercel build
5. **Distribute**:
   - Buffer schedules social posts
   - Mailchimp sends to subscribers
6. **Measure**:
   - PostHog tracks page views
   - Analytics measure engagement
   - Notion documents learnings

Key Integration Points

GitHub ↔ Vercel ↔ Analytics

Setup:

# Connect GitHub repo to Vercel
vercel link

# Add PostHog environment variables
vercel env add NEXT_PUBLIC_POSTHOG_KEY
vercel env add NEXT_PUBLIC_POSTHOG_HOST

# Every push triggers:
# 1. Vercel build
# 2. PostHog tracking activation
# 3. Analytics data collection

Tally ↔ Mailchimp ↔ Gmail

Email Workflow:

// Tally webhook sends to Mailchimp
// Mailchimp automation:
// - Day 0: Welcome email
// - Day 2: Feature introduction
// - Day 7: Ask for feedback

// Gmail receives:
// - User replies (manual response)
// - Mailchimp notifications
// - Feedback submissions

Buffer ↔ Analytics ↔ Notion

Content Analytics Loop:

1. Schedule posts in Buffer
2. Posts include UTM parameters:
   - `?utm_source=twitter&utm_campaign=launch`
3. PostHog tracks traffic from social
4. Review analytics in PostHog
5. Document insights in Notion:
   - Which platforms drive signups?
   - What content resonates?
   - Optimal posting times?
6. Refine Buffer strategy based on data

Pro Tip: Setup weekly review ritual using this stack:

  • Monday: Check PostHog analytics (what happened?)
  • Wednesday: Review Sentry errors (what broke?)
  • Friday: Document learnings in Notion (what did we learn?)
  • Sunday: Plan next week in GitHub Projects (what's next?)

Real-World Example

SaaS Product: "DevTimer" (Time Tracking for Developers)

Month 1 Results:

  • 127 signups (Tally → Mailchimp → Supabase)
  • 89 active users (PostHog tracking)
  • 12 bugs fixed (Sentry → GitHub → Vercel)
  • 23 features shipped (GitHub → Vercel)
  • $0 infrastructure costs

Tools in Action:

  • Cursor AI: Wrote 70% of initial codebase
  • Supabase: Handled all user data and auth
  • Vercel: 847 deployments (every push)
  • PostHog: Tracked 12,000+ events
  • Sentry: Caught 12 critical errors
  • Buffer: Scheduled 60 social posts
  • Mailchimp: Sent 400+ emails
  • Notion: 150+ pages of documentation

Reality Check: The free tier limits will appear around Month 2-3:

  • PostHog: 1M events/month (upgrade to $0-20/month)
  • Mailchimp: 1,000 contacts (upgrade to $13/month)
  • Supabase: 500MB database (upgrade to $25/month)

Total cost at scale: ~$58/month for 1,000+ users
