Most n8n examples online are trivial: connect Gmail to Slack, notify a channel when a row is added to a sheet. Useful for learning the tool, useless for understanding what it can do in a real business. Here are 8 automations we've actually built and deployed for clients.
1. Invoice reconciliation pipeline
What it does: ingests PDF invoices from email attachments, extracts structured data with Claude Vision, matches each invoice against open POs in a PostgreSQL database, auto-approves matches above 98% confidence, and sends a Telegram alert for exceptions with the discrepancy highlighted.
Details:
- Trigger: email received with PDF attachment
- Tools connected: Gmail, Claude API, PostgreSQL, Telegram
- Outcome: 97%+ invoices processed without human involvement, monthly close time cut from 5 days to 1
2. Lead enrichment and qualification
What it does: when a form is submitted, the workflow fetches company data from Apollo, passes the enriched record to Claude to score ICP fit (1-5) with reasoning, routes high-scoring leads to a specific rep in the CRM with a Slack notification, and drops low-scoring leads into an automated nurture sequence.
Details:
- Trigger: webhook from website form
- Tools connected: Apollo, Claude API, HubSpot, Slack
- Outcome: rep research time cut from 2+ hours/day to 20 minutes
3. Production reporting bot
What it does: field operators submit production numbers via Telegram throughout the day. n8n aggregates all inputs, calculates totals and variances against targets, Claude formats a plain-English daily summary, and leadership receives the report in Telegram each evening without anyone compiling it manually.
Details:
- Trigger: scheduled (6pm daily) + Telegram message listener
- Tools connected: Telegram Bot API, PostgreSQL, Claude API
- Outcome: daily reporting shift from 45 minutes of manual aggregation to zero
4. WhatsApp customer support
What it does: incoming WhatsApp messages are classified by Claude into categories (order status, returns, product question, complaint, other). FAQ-type queries are answered directly from a knowledge base. Complaints and complex queries are routed to a human with a summary. All interactions are logged to the CRM with classification and resolution status.
Details:
- Trigger: incoming WhatsApp message via Business API webhook
- Tools connected: WhatsApp Business API, Claude API, HubSpot
- Outcome: 75% of queries handled without human, response time under 2 minutes 24/7
5. Competitor monitoring
What it does: every Monday at 7am, n8n scrapes the pricing pages and feature pages of 5 competitor sites. Claude compares the current content to the version from last week and writes a brief highlighting what changed - new pricing, removed features, new product announcements. The brief lands in Slack before the team starts their week.
Details:
- Trigger: weekly cron (Monday 7am)
- Tools connected: HTTP scraper, PostgreSQL (stores previous versions), Claude API, Slack
- Outcome: competitive changes caught immediately instead of weeks later
6. Contract expiry monitoring
What it does: a daily job queries a PostgreSQL contracts table for contracts expiring in the next 30, 60, and 90 days. For each one, Claude drafts a personalized renewal outreach email using the contract details. Drafts go into a review queue in Notion. The sales rep reads and approves or edits, then sends. No contract slips through unrenewed.
Details:
- Trigger: scheduled daily
- Tools connected: PostgreSQL, Claude API, Notion
- Outcome: contract renewal rate increased, manual tracking spreadsheet eliminated
7. E-commerce abandoned cart recovery
What it does: when a Shopify checkout is abandoned, n8n waits 2 hours, then passes the cart details (products, prices, customer history) to Claude. Claude writes a personalized recovery email referencing what was left in the cart. The email is sent via Klaviyo from the brand's sending domain. Not a template - a generated email specific to that cart.
Details:
- Trigger: Shopify webhook (checkout abandoned)
- Tools connected: Shopify, Claude API, Klaviyo
- Outcome: recovery rate 2x compared to previous template-based sequence
8. Supplier reorder automation
What it does: a daily job checks inventory levels for each SKU in a Google Sheet. When a SKU drops below the reorder threshold, Claude drafts a purchase order email to the supplier including SKU, quantity needed, and delivery address. The draft goes to a Telegram approval queue. One tap to send. All orders are logged to a tracking sheet.
Details:
- Trigger: scheduled daily
- Tools connected: Google Sheets, Claude API, Gmail, Telegram
- Outcome: stockouts eliminated, reorder process cut from 1 hour to 5 minutes per week
Getting started with n8n
n8n cloud starts at $20/month for individuals and small teams. Self-hosted runs on any VPS (DigitalOcean, Hetzner) for $30-50/month with no execution limits. The learning curve is real - plan a day or two to get comfortable with the interface before building production systems. If you need something running in production quickly and reliably, working with an agency that knows the platform is faster than learning it from scratch.
