Short answer
Six layers: Meta's per-message fees (which depend on the message category and the recipient's country), your WhatsApp platform or provider fees, AI model usage, the one-off build scope, the integrations with your CRM and calendar, and ongoing maintenance. Quotes only compare fairly when each layer is itemised, so ask every vendor to separate them and check the Meta rate card yourself.

A WhatsApp chatbot is a one-off build plus several running costs that belong to different companies. Some go to Meta, some to a platform, some to the AI provider and some to the person who built and maintains it. That is why two quotes that look the same can differ by a lot after the first year. This page lists the layers rather than quoting figures, because the real numbers depend on your volume, countries and scope.
Start with Meta's messaging fees. As of November 2026, Meta charges per delivered message on the WhatsApp Business Platform, with the rate depending on the message category (for example marketing, utility, authentication or service) and on the country of the recipient. Rules about which messages are free, such as replies within the customer service window, have changed over time, so read the current rate card instead of relying on a vendor's summary.
Outbound marketing messages usually cost more than replies to people who message you first, so a bot that mostly answers inbound enquiries has a different cost profile from one that sends broadcasts. Volume matters, and so does how many conversations the AI handles end to end instead of handing to a person.
Scope creep is the other driver. A bot that answers five common questions and captures a lead is a very different project from one that books, quotes, takes payments and updates three systems. Starting with one workflow and measuring it before widening keeps both cost and risk down.
Use these to make hidden costs visible before you sign. Get the answers in writing, and compare quotes only once every vendor has itemised the same layers.
On Meta's WhatsApp Business Platform pricing page and rate card, which list rates by message category and by country. Check it directly, because rates and rules are updated and a third-party summary may be out of date.
Typically yes, either directly or passed through by the platform, sometimes with a markup. Ask the provider to show the Meta portion and its own fee as separate lines.
Meta's message rates depend on the recipient's country, so a Lebanese audience and a UAE or Saudi audience can be billed differently. The build and maintenance work is largely the same, but local language testing and integrations can differ.
Because the real cost depends on your volume, channels and integrations. Tarek Abou Rjeily scopes first, through a 3-working-day diagnostic or a 48-hour AI Audit, then gives a fixed written quote before any build begins. If scoping shows that a provider's ready-made inbox or the WhatsApp Business app is enough, that is the answer you get, and no build is quoted.
