AI receptionist on WhatsApp: what it does, costs and the rules

What does an AI receptionist on WhatsApp actually do?

It's an assistant connected to your business's WhatsApp number. It reads each message, works out what the person wants and replies from the information you've given it: services, opening hours, location, prices, booking rules. It doesn't make things up, and it doesn't wander into topics you haven't signed off.

What it handles most often:

• the questions you answer ten times a day: "how much is it?", "have you got anything tomorrow?", "where do I park?";
• booking straight into your calendar, with a confirmation;
• rescheduling and cancellations, by your rules;
• collecting the details you need for a quote, so nobody has to ask twice;
• handing over to a person when it doesn't know, when the customer is unhappy, or when they ask.

What the AI handles and what stays with your team

What the customer writes	What the AI receptionist does	What stays with a person
Opening hours, location, services	Answers from your approved information	Nothing, as long as the information is current
"How much is it?"	Quotes the exact price from your list	Discounts, negotiation, special offers
"Can I book in?"	Finds a free slot, books it and confirms	Exceptions: emergencies, out-of-hours requests
Rescheduling or cancelling	Handles it by the rules you've set	Cases involving fees or disputes
A complaint, an unhappy customer	Acknowledges it and hands over straight away	The actual conversation
Medical, legal or technical questions	Doesn't answer on substance; hands over	The specialist answer
"Can I speak to someone?"	Hands over immediately	Everything from there on

Our rule of thumb: if someone on your team gives the same answer every time, by the same rules, the AI can take it. If every case needs judgement, it stays with a person, and the AI just gets things ready for them.

How much does an AI receptionist on WhatsApp cost?

There are three separate costs, and it's worth seeing all of them before you start.

1. Building and running it

At SWAGG, an AI receptionist is an automation like any other, at the same price: €490 once to build, test and launch it, then €49/mo. The monthly fee covers running, monitoring, fixes and up to an hour of small changes a month. It's live in 7–14 days. Prices are final: we're not VAT-registered, so nothing gets added on the invoice.

2. WhatsApp messages, paid to Meta

Meta's official WhatsApp Business Platform pricing page (checked on 22 October 2026) sets out the model like this:

• Per message, not per conversation. Since 1 July 2025, Meta charges for each message a business delivers to a customer. Messages customers send to you are free.
• The price depends on category and country. Template messages are marketing, utility (transactional or informational) or authentication; free-form replies are service messages. Rates are set per category and per recipient market.
• The 24-hour window. When a customer messages you, a 24-hour customer service window opens, and it resets with every new message from them. Inside it you can reply freely, automation included. Outside it, you can only send template messages.
• The 1 October 2026 change. Meta has resumed charging, per message, for service messages beyond the first 1,000 delivered each month on each business phone number, and for utility messages sent inside the 24-hour window, which had been free since July 2025.
• Click to WhatsApp ads. If someone messages you from one of these ads in the Android or iOS app and you reply within the service window, a free entry point window opens that can stay open for up to 7 days.

The same page says Meta only changes rates on the first day of a quarter, so check them before you set a budget. When you estimate, count messages, not conversations: a single booking can mean five or six replies from the assistant. A reminder you send on your own initiative, when the customer hasn't written in the last 24 hours, is a template message and is charged separately.

3. The AI model

The model that reads the messages and writes the replies is billed by usage. You pay both the model and the WhatsApp messages at their actual cost, with no mark-up from us, and we estimate them on your volumes before we start.

Do you have to tell customers they're talking to an AI?

Yes. Regulation (EU) 2024/1689, the AI Act, says in Article 50(1) that AI systems intended to interact directly with people must be designed so that those people are told they're dealing with an AI system. The only exception is where that's obvious to a reasonably well-informed, observant and circumspect person. Article 50(5) adds that the information must be given in a clear and distinguishable way, at the latest at the first interaction.

When does it apply? Article 50 has no date of its own, so it follows the general application date in Article 113: 2 August 2026. The "AI Omnibus" simplification package, in force since 27 July 2026, pushed back other deadlines, but the consolidated text on the European Commission's AI Act Service Desk doesn't mark paragraph 1 as amended.

In practice, don't lean on the "it's obvious" exception. Have the assistant's first message say what it is: "Hi! I'm the virtual (AI) assistant for X Clinic. I can help with bookings and information, or put you through to a colleague." Strictly speaking, the Article 50(1) duty falls on whoever builds the system, but the conversation carries your business's name, so it's your reputation on the line. The receptionists we build never pretend to be human.

WhatsApp's own rules: opt-in and a route to a person

On top of the law, WhatsApp has its own rules for businesses: the WhatsApp Business Messaging Policy, last updated on 23 September 2026. Three of them matter for an AI receptionist:

• Opt-in. You may only contact someone who has given you their number and confirmed they want to hear from you. For reminders, or anything else you send unprompted, get that permission first.
• A route to a person. Automation is allowed when replying within the 24-hour window, but you must offer prompt, clear and direct escalation paths: a hand-over in the chat, a phone number, email or a support form.
• Opting out. If someone asks you to stop messaging them, on WhatsApp or anywhere else, you must respect it.

GDPR: what happens to your customers' messages?

A WhatsApp conversation is full of personal data: a name, a phone number, sometimes details of a problem or an appointment. The GDPR principles, as the European Commission summarises them, boil down to a short checklist:

• A legal basis. When a customer messages you to book, processing is needed to take the steps they've asked for before a contract. Anything beyond that needs its own basis, consent for example.
• Only the data you need. The assistant asks only for what you'll use. For a booking, that's usually a name, the service and a time.
• The shortest time possible. Set a period after which conversations are deleted or reviewed.
• Transparency. Explain in your privacy notice how conversations are used and who processes them.
• Security. Appropriate technical and organisational measures: access only for people who need it, accounts in the business's name.

We build every automation on your own accounts. We tell you in writing what data it uses and where it's stored, and where we can, we choose providers with servers in the EU. This guide is general information, not legal advice; for sensitive cases such as health data, speak to a lawyer or your data protection officer as well.

When an AI receptionist is worth it, and when it isn't

It pays off where messages arrive often and slip through easily: in the evening, at weekends, while you're with a client. The typical cases are clinics, salons and practices that live on bookings, service businesses that field lots of quote requests, and small teams where the owner is still answering the phone at night.

It isn't worth it if you get a handful of messages a week and already reply quickly, or if every enquiry is unique and needs a long conversation. There, an automatic confirmation and a person who answers fast will do more. Not sure which camp you're in? Our Business X-ray shows you in a few minutes where the time goes.

How it gets set up, step by step

1. You list the questions that keep coming up. Your "how much", "any availability", "where do I park" list is the starting point.
2. We agree the rules in writing. What it may say, which prices it quotes, what it stays away from and when it hands over.
3. We connect the accounts. Your number on the WhatsApp Business Platform, your calendar, and your CRM or invoicing software if needed.
4. We test on real cases. Genuine messages from your business, not textbook examples, so we can see where it needs to hand over.
5. We launch and keep watching. We read the conversations in the first weeks and adjust whatever isn't working; fixes are covered by the monthly fee.

The whole thing takes 7–14 days. What matters most is how quickly we get access to your accounts.

One automation, a bundle, or AI in your business?

It depends how clearly you know what you need. There's more detail on our AI automation page:

• One automation, €490 + €49/mo: you know exactly what's wrong, say WhatsApp messages going unanswered in the evening. Booking reminders are a separate automation, at the same price.
• Customers from ads, €990, then €239/mo from month 2: a sales landing page, tracking setup, one AI automation (a WhatsApp receptionist, for example) and the first month of Ads Start.
• The AI audit, €190, in 5 business days: you feel you're losing time but can't say where. If the report doesn't help, you get your money back.
• AI in your business, €1,990, in 4 weeks: the audit, 3 automations and team training. If you've already paid for the audit, it's deducted from the price.

Your next step

We use the automations we sell: anyone who books a call on swagg.studio automatically gets the Google Meet link and the reminders. If you'd like something similar on your business's WhatsApp, there are two ways in:

• In the configurator, pick the automation and get a written proposal on the spot, at the final price. Reserve within 24 hours with €99 and you get 5% to 20% off, depending on the quote's value; the €99 comes off your deposit and you can ask for it back within 3 days. The audit, AI in your business and ready-made bundles get no extra discount.
• If you'd rather talk first, book a free 30-minute call and tell us what messages you get and how often.
