WhatsApp AI Chatbot for Irish Businesses: Setup, Rules and Real Costs

Quick answer: WhatsApp is where Irish customers actually message. Here is how a compliant AI chatbot works on the Business Platform, what the message-window rules mean in practice, and what it costs per conversation.

Answer Summary

A WhatsApp AI chatbot connects an AI assistant to a verified WhatsApp Business Platform number so customers can ask questions, book appointments and get updates by message. For Irish businesses it suits high-message-volume trades, clinics, salons and hospitality. It requires a verified business account, opt-in before you message first, and template approval for anything outside the 24-hour reply window.

<a id="why"></a>Why WhatsApp rather than web chat?

Because of where the customer already is. Web chat only works while someone is on your site; WhatsApp continues after they close the tab, keeps the history, and reaches them with an update three days later without an email going unread. For trades and service businesses there is a second advantage that is easy to overlook: photos. "Send me a picture of the boiler" is a normal WhatsApp request and an awkward web-chat one, and photo triage saves wasted call-outs.

<a id="requirements"></a>What do you need before you start?

None of this is difficult, but it is sequential, and the verification step is the one that slips timelines.

  • A WhatsApp Business Platform account through Meta or a business solution provider. Personal WhatsApp and the free Business app cannot run a compliant automated assistant at volume.
  • A dedicated phone number not already registered to WhatsApp.
  • Business verification with Meta — expect to supply company details; allow days, not hours.
  • A display name that matches your business.
  • Approved message templates for anything you send outside an open conversation window.

<a id="window"></a>How does the 24-hour window work?

This rule shapes every WhatsApp build. When a customer messages you, a 24-hour window opens in which you can reply freely with any content. Outside that window you may only send a pre-approved template message. You cannot message someone first without opt-in and an approved template. Practically, that means: Designing as if you can message anyone at any time is the most common way these projects fail approval.

  • Automated replies during the window can be conversational and AI-generated.
  • Booking reminders, quote follow-ups and delivery updates must be templates, approved in advance.
  • Your opt-in mechanism — a website checkbox, a QR code, a click-to-chat link — needs to be real and recorded.

<a id="capabilities"></a>What can the AI actually do?

A well-scoped Irish SME build typically handles: The handover matters. Nobody should have to repeat themselves to a human after five minutes with an assistant.

  • Answering questions from your prices, service area and policies.
  • Taking booking details and writing them to a live calendar.
  • Collecting photos for quoting and attaching them to a CRM record.
  • Sending appointment reminders and on-the-way notifications by template.
  • Handing over to a person, in the same thread, with full history.

<a id="cost"></a>What does it cost in Ireland?

Two layers again: A business handling 1,000 conversations a month typically lands under €150 a month all in. Check Meta's current Irish pricing at scoping — the rate card changes and we quote from the live one rather than from memory.

  • Build — from €4,250 for a single-number assistant with calendar or CRM write-back. Payments, multi-agent inboxes and multilingual handling push it higher.
  • Running — Meta charges per 24-hour conversation, not per message, with different rates by category (service, utility, marketing) and by country. For an Irish SME the practical range is usually €0.02–€0.09 per conversation, plus €20–€80 a month in model usage.

<a id="gdpr"></a>What are the GDPR obligations?

Message content is personal data, and the obligations are the ordinary ones applied properly:

  • Record opt-in with a timestamp and source.
  • Disclose the automated assistant at the start of the conversation.
  • Set a retention period for chat history and stick to it.
  • Process and store transcripts in the EU.
  • Provide a working opt-out — "STOP" should genuinely stop everything.
  • Cover WhatsApp explicitly in your privacy notice.

<a id="wrong"></a>What goes wrong most often?

  • Trying to run it on a personal number. It works for a fortnight, then it does not.
  • Templates written after the build. Approval takes time; write them early.
  • No opt-in record. The one thing you will be asked for if a complaint lands.
  • Marketing templates disguised as service messages. Meta enforces this, and the penalty is quality-rating damage that throttles your delivery.
  • No human escalation. WhatsApp feels personal; an unanswerable bot in that channel is worse than none at all.

How does a WhatsApp AI chatbot work?

It runs on the official WhatsApp Business Platform. When a customer messages your verified number, an AI assistant reads the message, answers from your own prices and policies, and can book appointments, collect photos or write to your CRM before handing complex cases to a person.

Can I run a WhatsApp chatbot on my normal WhatsApp number?

No. Automated assistants require the WhatsApp Business Platform with a verified business account and a dedicated number not already registered to WhatsApp. Personal accounts and the free Business app are not built for compliant automation at volume.

What is the WhatsApp 24-hour messaging window?

When a customer messages you, a 24-hour window opens during which you can reply with any content. Outside that window you may only send pre-approved template messages, and you cannot message someone first without recorded opt-in and an approved template.

How much does a WhatsApp AI chatbot cost in Ireland?

A build with calendar or CRM write-back starts at about €4,250. Running costs are charged per 24-hour conversation rather than per message, typically in the range of a few cent per conversation, plus roughly €20 to €80 a month of model usage.

Is a WhatsApp chatbot GDPR-compliant?

It can be. Record opt-in with a timestamp and source, disclose the automated assistant at the start, keep transcripts in the EU under a defined retention period, honour opt-out requests immediately, and describe WhatsApp messaging in your privacy notice.

Can a WhatsApp AI chatbot take bookings?

Yes. It reads live availability from your calendar or booking system, offers real slots inside the chat, confirms the appointment and sends reminders using approved template messages closer to the date.

What are the WhatsApp Business API rules an Irish business needs to know before setting up a chatbot?

WhatsApp requires businesses using automated messaging through its official Business API to get customer opt-in before sending proactive messages, and template messages used outside an active conversation window need pre-approval from WhatsApp itself, which can take a few days. Businesses cannot simply message any phone number that has previously contacted them without following these opt-in and template rules, and doing so risks the business account being restricted. Responding to a customer who messages first is generally more straightforward, since that opens a standard conversation window during which more flexible replies are allowed. Any Irish business setting up a WhatsApp chatbot should have this compliance step handled properly during setup rather than discovering restrictions after launch.

How much does it typically cost to run a WhatsApp AI chatbot on an ongoing basis?

Beyond the initial setup, ongoing costs usually include a small per-conversation fee charged by WhatsApp itself once free conversation limits are exceeded, plus the cost of the underlying AI service processing and generating responses, which scales with message volume. For a small Irish business handling a modest volume of enquiries, monthly running costs are typically manageable, but a business expecting high message volumes, such as a busy retailer during a sale period, should ask for a volume-based cost estimate rather than assuming a flat monthly fee will cover everything. Digital Bridge's AI projects are quoted in writing for setup, with ongoing running costs discussed transparently based on expected message volume before the project begins.
