What is the best AI sales bot for WhatsApp Business? It is the one that does four jobs in the same chat: it answers with your real prices, qualifies the lead, books the appointment and sends the payment link, and it hands the customer to a person when it should. To choose one, check that it runs on Meta's official WhatsApp Business Platform, that your customers can always reach a human, and how much you will pay Meta in message fees on top of the tool. ## The best AI sales bot for WhatsApp Business does four jobs in one chat A sales bot has to carry the conversation all the way to a booked appointment or a payment. - **It answers with your real information.** Prices, hours and services, in your tone, instead of generic replies. - **It qualifies.** It asks what the customer needs and when, so you know who is ready to buy. - **It books.** It offers open slots from your calendar and confirms the appointment in the chat. - **It collects.** It sends a payment link at the moment the customer says yes. A WhatsApp bot that only answers with your real information is a support bot. A support bot answers questions, but it will not take a sale to the finish line on its own. ## A small business can automate simple WhatsApp replies for free with the WhatsApp Business app The free WhatsApp Business app handles fixed answers you write in advance. WhatsApp describes the WhatsApp Business app as free to download, with automated greeting and away messages, quick replies with pre-written answers to common questions, and labels to organize your chats. The Business app's greetings, away messages and quick replies are written once, in advance. An AI sales bot is what you add when every answer depends on the question, your calendar and the amount you need to charge. ## Meta's rules decide which WhatsApp bots are safe to use An AI bot connects to WhatsApp through Meta's WhatsApp Business Platform. Three rules matter when you compare options. - **Permission first.** Meta's WhatsApp Business Messaging Policy says you may only contact people who gave you their number and opt-in permission to receive your messages. - **A clear path to a human.** The same policy allows automation when you reply within the 24-hour window, but it requires "prompt, clear, and direct escalation paths", such as an in-chat transfer to a human agent, a phone number or an email. - **General-purpose AI is not the product.** Section 4.7 of the Meta Terms for WhatsApp Business Platform (last modified September 23, 2026) strictly prohibits AI providers, such as large language model and general-purpose AI assistant providers, from using the platform to offer those technologies when they are the "primary (rather than incidental or ancillary) functionality", with exceptions for certain countries. Meta decides that "in its sole discretion", and the same section lets a business retain an AI provider as its solution provider. Before you sign with any WhatsApp bot vendor, ask them to show you how their bot meets Meta's three rules: permission first, a clear path to a human, and AI that works for your business instead of being offered as a general-purpose assistant. ## WhatsApp chatbot pricing has two parts: the tool and Meta's fees Whatever bot you pick, Meta charges for messages separately from the software. Meta's developer documentation says it has charged "on a per-message basis" since July 1, 2025, that businesses are only charged when a message is delivered, and that it does not charge for messages users send to your business. The rate depends on two things: the message category (marketing, utility, authentication, service or Meta Business Agent) and the country calling code of the person who receives it. Since October 1, 2026, Meta also charges for service messages, the free-form replies your business sends while a conversation is open, after a free tier of 1,000 per business phone number per month. The customer service window is the open conversation between your business and a customer. It lasts 24 hours from the customer's last message, and outside it a WhatsApp bot can only send pre-written template messages. On top of Meta's fees you pay for the tool. Respond.io's pricing page, checked on October 27, 2026, lists its Advanced plan, which includes AI Agents and AI Agents for voice calls, at $279 a month billed yearly ($349 billed monthly), and says "WhatsApp fees are not included in any respond.io subscription". Wati's pricing page also says that additional message costs apply. When you compare quotes, add both parts: the subscription and Meta's fees for the volume you expect in your customers' countries. ## A subscription platform or a bot built for you depends on how you sell Subscription WhatsApp bot platforms, such as Respond.io or Wati, charge a plan for the tool, and Meta's message fees come on top. Respond.io lists AI Agents in its Growth and Advanced plans, and Wati describes a shared inbox with an AI copilot and autonomous AI agents in its plans. A bot built for your business fits when it has to work with your own prices, your calendar and your payment provider, and when you want to keep the system if you change providers. With any option, ask five questions in writing: can you set the questions it asks to qualify a lead, can it offer open slots from your calendar and book them, can it send a payment link from your own provider, who owns the conversation data, and what happens to the bot if you stop paying. ## MAGIA Solo gives you a WhatsApp assistant that answers, books and collects in 15 days MAGIA Solo is our package for professionals and small businesses. In 15 days we hand you a system that answers, books and gets you paid: an assistant that handles WhatsApp day and night with your voice and your prices, offers your open slots, sends reminders and shares a payment link in the chat. It also includes your professional page and a dashboard with clients, appointments and sales. The MAGIA Solo assistant is set up to stay within what it knows about your business, and when a question gets sensitive or falls outside its scope, it hands it to you instead of improvising. Code, data, domain and accounts are in your name from day one, and we work in Spanish and English. MAGIA Solo is a one-time build of $4,500 USD, with training and 6 months by your side included. Monthly operations (hosting, WhatsApp and the AI that answers) are paid at cost, directly to the providers and in your name. If you want the MAGIA Solo system to stay hosted and operated by Catalizadora, that requires an active plan, from $99 USD a month. MAGIA Solo is designed for consultants, coaches, independent professionals and teams of 1 to 5. If your team is larger, MAGIA Core is built for companies of 20 to 300 people, and on a first call we tell you which path fits. The MAGIA Solo build is a one-time payment, made by milestones, instead of a monthly subscription. See everything that is included and how the 15 days work on the [MAGIA Solo page](/en/magia/solo), or compare every path on [our pricing page](/en/pricing). ## Preguntas frecuentes ### What is the best AI sales bot for WhatsApp Business?
