I've automated hundreds of business processes for clients using n8n. Here are the 5 patterns that consistently deliver the biggest ROI - and the exact workflow for each.

n8n hits a sweet spot for AI-heavy workflows:

Every B2B company needs to enrich inbound leads with company data, social profiles, and intent signals.

```
Webhook (form submission)
  → HTTP Request (Clearbit/Apollo API for enrichment)
  → If/Else (route by company size)
  → Postgres (store enriched data)
  → Slack (notify sales team)
  → Email (personalized auto-reply)
```

**Time saved**: 15 min per lead × 100 leads/month = 25 hours/month

**Cost**: $0.10 per enrichment API call

PDFs, contracts, invoices - extract structured data and route for action.

```
Email trigger (Gmail watch)
  → Download attachment
  → Mistral OCR (extract text from PDF)
  → GPT-4 structured output (extract fields)
  → If/Else (validate extracted data)
  → Database insert
  → Slack notification with extracted data
  → Auto-reply with summary
```

**Use cases**: Contract review, invoice processing, resume parsing

**Time saved**: 20-40 hours/week for legal and finance teams

Turn one piece of content into 10 social posts, email newsletters, and Slack updates.

```
Webhook (new blog post published)
  → GPT-4 (generate 5 tweets, LinkedIn post, email snippet)
  → HTTP Request (Buffer API - schedule posts)
  → HTTP Request (Mailchimp API - send newsletter)
  → Slack (notify team)
  → Database (track all posts)
```

**Result**: 5x more content distribution with same writing effort

**Time saved**: 8 hours/week for marketing teams

Auto-respond to support tickets with AI, escalate to humans when needed.

```
Webhook (Zendesk/Intercom new ticket)
  → AI Agent (LangChain + RAG on docs)
  → If confidence > 0.8: send auto-reply
  → If confidence < 0.8: assign to human
  → Update CRM
  → Track resolution time
```

**Time saved**: 60-70% of tier-1 support tickets handled automatically

**Quality**: Better than junior humans, escalation path for complex

Lead scoring, follow-up sequences, meeting scheduling - all on autopilot.

```
New lead in CRM
  → Enrichment API (company info)
  → AI scoring (GPT-4 analyzes fit)
  → If score > 80: auto-add to high-priority sequence
  → If score 40-80: nurture sequence
  → If score < 40: disqualify + remove
  → Meeting link auto-generated for hot leads
  → Slack notification to AE
```

**Result**: 3x more qualified meetings booked

**Time saved**: 30 hours/week for sales team
