In many countries, WhatsApp is where customers already talk to businesses. A WhatsApp chatbot lets you answer questions, take enquiries, confirm orders, and book appointments in a channel your customers use every day, without asking them to install anything new.
This guide explains how business chatbots work on WhatsApp, the rules to know, and how to get started.
WhatsApp Business app vs WhatsApp Business Platform
There are two different products, and the difference matters:
- WhatsApp Business app. A free app for small businesses, with basics like quick replies and labels. It is managed from a phone and has limited automation.
- WhatsApp Business Platform (API). The official way for medium and large businesses, or any business that wants real automation, to connect WhatsApp to software. This is what chatbots use.
To build a chatbot, you work with the Business Platform, usually through Meta's Cloud API or an approved provider.
What a WhatsApp chatbot can do
- Answer frequently asked questions, any time of day
- Share order and delivery status
- Book, confirm, and remind people of appointments
- Collect lead details and pass them to your CRM
- Send updates and notifications customers have agreed to receive
- Hand the chat to a human agent when needed
Rules you need to know
WhatsApp has policies designed to protect users. The details change, so always check the current official terms, but the main ideas are:
- Opt-in. You need permission from people before messaging them.
- The customer service window. After a customer messages you, you can reply freely for a limited period. Outside that window, you generally need to use pre-approved message templates.
- Templates. Messages you start, such as reminders or updates, must use templates that WhatsApp approves.
- Content policies. WhatsApp prohibits certain types of content and misuse, and restricts some kinds of general-purpose AI assistants on the platform. Business-specific bots for support and sales are the intended use.
- Business verification. A verified business profile builds trust and may be required for some features.
What to plan for in cost
Costs usually come from:
- Development. Building the conversation flows, knowledge, and integrations.
- Platform and provider fees. Meta charges for certain message categories, and providers add their own fees.
- AI usage. If the bot uses a language model, you pay for the text it processes.
- Maintenance. Updating content, templates, and integrations.
Because pricing models change, get an up-to-date estimate from your provider rather than relying on old figures. Our guide to chatbot cost factors explains what drives price.
Designing a good WhatsApp bot
- Be short and clear. People read on small screens.
- Use buttons and lists for common choices, which reduces typing.
- Give a human option. Make it easy to reach a person.
- Support your customers' languages, including mixed-language messages where relevant.
- Respect privacy. Do not ask for sensitive information unless needed, and explain how you use it.
Step-by-step start
- Pick one goal, such as order tracking or appointment booking.
- List the top questions and the data the bot needs.
- Set up a WhatsApp Business account and a number dedicated to the bot.
- Build and connect the bot to your systems, such as your CRM or order tool.
- Create templates for any messages you will send first.
- Test with real conversations, then launch to a small group.
- Measure and improve: resolution rate, handovers, and customer feedback.
Common mistakes
- Messaging people who have not opted in
- Using a personal or shared number
- No fallback to a human
- Trying to automate every conversation on day one
