How to Set Up an AI WhatsApp Assistant for Your Irish Trade Business
WhatsApp is now the default channel for Irish trade enquiries. Customers expect a fast reply — and if you're on a job or it's 9pm, you're losing those leads. An AI WhatsApp assistant fixes this in 10 minutes (simple) or 2–3 hours (advanced).
Quick Answer
Irish tradespeople can set up an AI WhatsApp assistant in two ways: the simple version uses WhatsApp Business's free auto-reply feature (10-minute setup); the advanced version connects n8n, Claude and the WhatsApp Business API to send intelligent, personalised responses automatically (2–3 hour setup). The advanced version costs €22/month (Claude) plus a free tier WhatsApp API provider like AiSensy.
Why is WhatsApp the right channel for Irish trade businesses?
In Ireland, WhatsApp has largely replaced SMS and often replaces phone calls for trade enquiries. Customers find your number online or from a neighbour and WhatsApp you — because it's easier than calling and faster than email.
The problem: you're on a job, your phone is in your pocket, and you see the message 3 hours later. By that point, the customer has texted two other tradespeople. The one who replied first gets the job.
An auto-reply doesn't close the job — but it holds the lead. It tells the customer you've received their message and you'll be in touch. That acknowledgement dramatically reduces the likelihood they'll contact someone else before you call them back.

How do you set up the simple version? (10 minutes)
- Download WhatsApp Business from the App Store or Google Play (free)
- Set up your business profile: name, trade, area, working hours, website
- Go to Settings → Business Tools → Away Message — enable and write your auto-reply
- Go to Settings → Business Tools → Greeting Message — write your first-time contact message
- Save 3–5 Quick Replies for your most common questions (pricing, callout charge, availability)
Away Message Template (copy and paste)
Hi [Name], thanks for getting in touch with [Business Name]. We're either on a job or outside working hours right now. We'll get back to you within 2 hours during the working day (Mon–Fri 8am–6pm), or first thing tomorrow morning. If it's an emergency, please call [phone number]. — [Your Name]
How do you set up the advanced version? (2–3 hours)
The advanced version uses the WhatsApp Business API (via AiSensy or Twilio), n8n, and Claude to send intelligent replies — not just templates.
- Set up AiSensy — Create a free account at AiSensy.com and connect your WhatsApp Business number. AiSensy provides the webhook URL that n8n listens on.
- Create the n8n workflow — Add a Webhook trigger node in n8n. Configure it to receive the AiSensy payload when a new WhatsApp message arrives.
- Pass to Claude — Add an HTTP Request node in n8n calling Claude's API. Include the customer's message and a prompt: "You are a customer service assistant for [Business Name], a [trade] business in [County]. Reply to this WhatsApp enquiry professionally and ask a qualifying question if appropriate."
- Send the reply — Add an AiSensy send node to reply to the customer's WhatsApp with Claude's output.
- Log to Google Sheets — Add a Google Sheets node to record: customer name/number, message, timestamp, and AI reply.
This setup runs 24/7. You review leads in the morning in your Google Sheet. For more on n8n workflows, see our guide on n8n for Irish small business.
What are the GDPR rules for WhatsApp for Irish businesses?
Three rules to be aware of when using WhatsApp for business in Ireland:
- Consent for marketing: You must have explicit consent before sending marketing messages on WhatsApp. Replying to an inbound enquiry is not marketing — it's customer service. No consent issue here.
- Data storage: WhatsApp message content stored in Google Sheets or similar tools is personal data under GDPR. Have a privacy policy that covers this and don't retain data longer than necessary.
- Sensitive data: Don't send health information, financial account details, or PPS numbers through WhatsApp or Claude. Standard trade enquiries (name, address, job description) are fine.
The Data Protection Commission's guidance on AI and GDPR is at dataprotection.ie. For most standard trade use cases, an AI WhatsApp assistant is straightforwardly compliant.

Frequently Asked Questions
Can I use WhatsApp to automatically reply to customer enquiries in Ireland?

What is AiSensy and is it free for small businesses in Ireland?

How do I connect WhatsApp to n8n for automatic replies?
Connect AiSensy to n8n via a webhook. When a WhatsApp message arrives, AiSensy sends it to n8n, which passes it to Claude for a reply, then sends the reply back via AiSensy. Full setup takes 2–3 hours and is covered in the 4-Week Programme.

"Thanks for getting in touch with [Business Name]. We're on a job or outside hours right now. We'll reply within 2 hours (Mon–Fri 8am–6pm) or first thing tomorrow. Emergency? Call [number]. — [Your Name]." Short, gives a timeframe, provides emergency contact.
