A WhatsApp AI assistant for a business is a bot connected to the official WhatsApp Business Platform that answers customers in Arabic or English from your own information: prices, services, opening hours, order status and bookings, and hands the conversation to a person when it should. It needs three parts: an approved WhatsApp Business number, an AI model limited to your content, and a link to your systems such as your store, CRM or booking calendar.
This guide explains how it works, what it costs to run, and what to decide before you build one.
What can a WhatsApp assistant do?
- Answer common questions about services, prices, delivery areas and policies, at any hour.
- Check order or booking status by reading from your store or system.
- Take bookings and leads: collect the customer's name, need and preferred time, then pass them to your team or CRM.
- Send updates such as order confirmations, delivery notices and appointment reminders.
- Hand over to a person when the customer asks, when the question is outside what the bot knows, or for complaints and payments.
How does it work?
- WhatsApp Business Platform. The assistant runs on Meta's official platform (the Cloud API), either directly or through an approved provider. The ordinary WhatsApp Business app on a phone is not built for this, and unofficial tools risk getting the number banned.
- Your knowledge. The AI model answers from your own documents and data, not from general knowledge. This is usually done by searching your content first and giving the model only the relevant parts, so answers stay accurate and on topic.
- Your systems. For order status, bookings or leads, the assistant calls your store, CRM or calendar through their APIs.
- Rules and handover. You decide what the bot may answer, what it must never promise, and when it passes the chat to a person, with the conversation history attached.
What does WhatsApp charge?
Since 1 July 2025, Meta charges per template message instead of per 24-hour conversation. In practice:
| Message type | Example | Cost |
|---|---|---|
| Service reply | Answering a customer who wrote to you, within 24 hours | Free |
| Utility template inside the 24-hour window | Order confirmation after the customer messaged you | Free |
| Utility template outside the window | Delivery notice days later | Charged per message |
| Authentication template | One-time login code | Charged per message |
| Marketing template | Offer or campaign | Charged per message |
Rates differ by the customer's country and by volume, so check Meta's current rate card. On top of this you pay for the AI model's usage and for hosting, which depend on the number of conversations.
What should you decide before building?
- Scope. List the 20–30 questions customers ask most. A focused assistant that answers these well beats a general one that guesses.
- Language and tone. Saudi customers write in Gulf dialect, Modern Standard Arabic, English and a mix. Test with real messages, not only formal Arabic.
- What the bot must not do. Promise discounts, confirm payments it cannot see, or give legal or medical advice.
- Handover. Who receives the chat, in which hours, and what the customer sees outside working hours.
- Personal data. Conversations contain names, phone numbers and sometimes addresses, so they fall under Saudi Arabia's Personal Data Protection Law. Decide where conversations are stored, for how long, and who can read them. Our guide to hosting and the PDPL covers this.
- Opt-in. Customers must agree before you send them template messages, especially marketing.
Note that Meta's WhatsApp Business terms restrict general-purpose AI chat services offered as the product itself. An assistant that serves your own customers about your own business is the intended use; check the current policy with your provider before launch.
How do you know it is working?
Track a few numbers from the first week:
- The share of chats the bot resolves without a person.
- How often it hands over, and why.
- Response time compared with before.
- Leads or bookings created through WhatsApp.
- Wrong answers found in a weekly review of a sample of conversations.
