Claude Code + n8n: The Automation Stack That Replaces 3 Employees

Most automation tools fall into two camps:

• No-code tools (Zapier, Make) are easy but dumb. They do if-then. They can’t think.
• Code-based tools (Python scripts, Node.js) are smart but fragile. They break when an API changes.

Claude Code + n8n is different. Claude Code handles intelligence (decision-making, reasoning, custom logic). n8n handles orchestration (connecting tools, scheduling, error handling, retries).

Together, they automate 90% of the repetitive work that employs 3 people in a typical company.

The Problem They Solve

Typical operations team spends time on:

1. Lead Qualification — Reading form submissions, researching companies, determining fit (15+ hours/week)
2. Invoice Processing — Entering invoices, matching to purchase orders, coding to GL account, forwarding approval (12+ hours/week)
3. Content Publishing — Formatting blog posts, resizing images, uploading, updating social links (10+ hours/week)
4. Report Generation — Collecting data from 5 sources, formatting Excel, emailing to stakeholders (8+ hours/week)
5. Client Followup — Checking if proposals were opened, following up with prospects, scheduling calls (10+ hours/week)

Total: ~55 hours/week of busywork. At $40/hour fully loaded, that’s $114,400 annually for one person doing this work.

Claude Code + n8n replaces that person. Not partially. Completely.

How It Works: The Architecture

You build two things:

1. Claude Code Skills (Intelligence Layer)

Skills that Claude Code can invoke to make decisions. Examples:

• /lead-qualifier — Evaluates if a lead fits your ICP
• /invoice-processor — Extracts line items, matches POs, suggests GL codes
• /content-formatter — Optimizes markdown, generates metadata, creates social snippets
• /report-generator — Pulls data, analyzes trends, writes executive summary

Each skill is 50-200 lines of markdown. It tells Claude what to evaluate and how.

2. n8n Workflows (Orchestration Layer)

Workflows that trigger skills, handle data, and act on results. Examples:

• “When new form submission arrives → call /lead-qualifier → if qualified → add to CRM → send email”
• “When invoice PDF lands in folder → call /invoice-processor → save data → create accounting entry”
• “When blog post is drafted → call /content-formatter → save formatted version → post to site + social”

n8n does all the heavy lifting: timing, retries, error handling, logging, scheduling.

Real Examples

Example 1: Lead Qualification Workflow

Manual process:

1. New form submission arrives
2. Someone reads it
3. They research the company (website, LinkedIn, Crunchbase)
4. They check if they fit your ICP (company size, industry, growth stage)
5. They determine priority level (hot, warm, cold)
6. They add to CRM
7. They send personalized follow-up email

Time: 20-30 minutes per lead.

Automated process:

Trigger: New form submission arrives in Slack webhook

Step 1: Extract form data
  - name, email, company, use case, budget

Step 2: Call Claude Code skill /lead-qualifier
  - Input: company name, use case, budget
  - Claude researches company, evaluates fit, scores lead

Step 3: Branch on score
  - If score > 80 (hot): continue to step 4
  - Else: save to followup queue, end

Step 4: Fetch from CRM (Salesforce API)
  - Check if company already exists

Step 5: Add/update contact in CRM
  - Company, contact name, email, lead score, qualification notes

Step 6: Send email
  - Use /email-ghostwriter skill to generate personalized response
  - Send via Gmail

Step 7: Create calendar event
  - Schedule intro call (10 days out)
  - Invite both parties

Step 8: Log in Slack
  - "#leads" channel: "New hot lead: Acme Corp"

Time: 90 seconds. Per 100 leads: 150 minutes saved = 2.5 hours/week.

Example 2: Invoice Processing Workflow

Manual process:

1. Invoice PDF arrives in email
2. Someone extracts: vendor, amount, line items
3. They match invoice to PO in system
4. They verify amounts match
5. They code to GL account
6. They create payment request
7. They forward to approver

Time: 15-20 minutes per invoice.

Automated process:

Trigger: Invoice PDF arrives in shared email (via IMAP)

Step 1: Download PDF, extract text (OCR)

Step 2: Call Claude Code skill /invoice-processor
  - Input: PDF text
  - Claude extracts: vendor, invoice #, amount, line items, terms
  - Output: structured JSON

Step 3: Query Supabase
  - Search POs for matching vendor + approximate amount

Step 4: Verify match
  - If amounts within 5%: mark as verified
  - Else: flag for manual review, end

Step 5: Call /gl-code-mapper skill

The Tech Stack

You need 5 things:

1. Claude Code — Intelligence layer (available from Anthropic)
2. n8n (self-hosted or cloud) — Orchestration engine
3. Skills — Markdown files defining Claude’s behavior (included in Claude Skills 360)
4. API keys — For each external tool (Salesforce, Stripe, Gmail, etc.)
5. Database — To log actions and results (Supabase, PostgreSQL, or Google Sheets)

The integration is straightforward:

n8n sends HTTP request to Claude Code API
  {
    "skill": "/lead-qualifier",
    "input": { company, use_case, budget },
    "context": "Evaluate if this lead fits our ICP"
  }

Claude Code processes
  → Runs the /lead-qualifier skill
  → Returns decision + reasoning
  {
    "qualified": true,
    "score": 87,
    "reason": "Series B SaaS, marketing focus, $50k+ budget"
  }

n8n receives response
  → Branches on "qualified"
  → Adds to CRM if true
  → Continues workflow

Real ROI

One 15-person marketing agency implemented Claude Code + n8n:

Before:

• 1 operations coordinator @ $50k/year
• Spent 40+ hours/week on:
  • Lead qualification (15h)
  • Invoice processing (12h)
  • Report generation (8h)
  • Client follow-up (10h)
  • Misc data entry (5h)

After (3 months to build + test):

• Automated 90% of the above
• Coordinator reduced to 10 hours/week administrative (scheduling, exceptions)
• Hired 0.3 FTE instead of full person
• Annual savings: $35k (salary + benefits)
• Time savings per week: 35 hours (reallocated to client work)

Result: Increased billable hours per employee by 25%. Revenue impact: +$150k/year.
