n8n for Automation — Connecting Your World Without Code
What n8n Is and Why It's Different
n8n is an open-source workflow automation platform similar to Zapier or Make (formerly Integromat), but with three key advantages: it can be self-hosted (your data stays on your infrastructure), it supports code nodes (you can write JavaScript or Python for complex transformations), and it has 350+ native integrations including a Claude/Anthropic node.
The core concept: a workflow is a series of nodes connected by edges. Each node receives data, transforms it, and passes it to the next node. Triggers can be webhooks, scheduled cron jobs, email receipt, form submission, or API events. Actions include sending emails, creating database records, calling APIs, generating documents, and messaging via Slack/WhatsApp/Telegram.
For Darkice Interactive, the highest-value n8n workflows: (1) New client intake — form submission triggers CRM record creation, Xero client setup, Toggl project creation, and welcome email. (2) BathCheck report notification — when an OT completes an assessment, trigger PDF generation, email to client, and Xero invoice creation. (3) Support ticket routing — inbound emails classified by AI and routed to appropriate team members or auto-responded.
Building Your First n8n Workflow with AI
n8n's AI nodes (Claude, OpenAI, and others) integrate directly into workflows, allowing you to add intelligence at any step. A practical example for BathCheck:
Workflow: New assessment submitted → n8n webhook receives JSON data → Claude node: 'Given this assessment data, generate a professional clinical summary in 200 words' → Format output into PDF template → Send PDF via email → Create Xero invoice → Update ClickUp task as complete.
This workflow would take 3–4 hours of developer time to build in code. In n8n, it's 30–60 minutes for someone with basic familiarity. The maintenance burden is also lower — non-developers can update the Claude prompt or change the email template without touching code.
n8n self-hosting: run n8n on a Digital Ocean droplet ($6–$12/month) or a Cloudflare Worker setup. For a small business, the Digital Ocean approach is simplest. Use n8n's Docker image and set up SSL with Caddy. Your entire automation infrastructure costs $10–$20/month and handles hundreds of workflow executions per day.
⚡ Today's Action
Identify the most repetitive manual task in your business that involves moving data between two systems (e.g., from a form to a spreadsheet, from a client email to a ClickUp task, from Xero to a client notification). Build an n8n workflow to automate it. Time how long it takes — this is your ROI baseline.
💡 Pro Tip
Start with n8n's cloud offering (free tier with 5 workflows and 500 executions/month) to learn the platform before self-hosting. Once you're confident in the workflows you need, migrate to self-hosted for unlimited executions and data control.
