1. Automated email routing and first response
How it works: Every inbound email hits an AI model that reads the content, classifies it (support request, sales inquiry, complaint, partnership, spam), and either routes it to the right inbox, sends an automated first reply, or flags it for human review.
Time to build: 3–4 hours. Time saved: 45–60 min/day for most teams.
Tools: n8n + Gmail API + Claude/GPT-4 API.
2. Automatic invoice and document data extraction
Supplier sends you a PDF invoice. Instead of manually opening it and copying numbers into your accounting tool, an AI reads the PDF, extracts vendor name, amounts, dates, and line items, and pushes them directly into your system.
Time to build: 4–6 hours. Time saved: 2–4 hours/week for businesses receiving 20+ invoices.
Tools: n8n + Google Drive trigger + AI extraction + Google Sheets or Xero API.
3. Lead qualification from contact forms
Someone fills out your contact form. An AI reads their message, company, and context, scores them based on your criteria (budget, fit, urgency), and sends you a prioritized summary. High-quality leads get an instant personalized reply. Low-fit inquiries get a polite automated response.
Time to build: 2–3 hours. Time saved: 30–60 min/day depending on lead volume.
4. Weekly reporting on autopilot
Every Monday at 8am, your system pulls data from your CRM, e-commerce platform, or spreadsheets, generates a summary with key metrics and trend annotations, and sends it to you and your team — formatted, readable, with highlighted anomalies.
Time to build: 4–8 hours. Time saved: 1–3 hours/week.
Tools: n8n scheduled trigger + data sources + AI summary generation + Gmail/Slack.
5. Onboarding document generation
New client or employee fills in a form. The system automatically generates all relevant documents (welcome email, contracts, NDAs, access credentials), sends them for e-signature, and creates the right records in your CRM or HR tool. Zero human steps between "form submitted" and "documents signed."
Time to build: 6–8 hours. Time saved: 2–4 hours per onboarding event.
Pick the one that takes the most time right now, or the one your team complains about most. That's your first automation. Build it, run it for a week, then add the second.
