WhatsApp Chatbot: What It Can Do and What It Costs Since October
Since October 1, 2026, answering a customer's question on WhatsApp also costs money, starting with the 1,001st message per number and month. For most small businesses, that changes little. For a chatbot that sends a lot of messages, it does. Here is what a WhatsApp bot can do today, how Meta bills for it and what you should sort out before you launch.
What a WhatsApp bot can do today
A good WhatsApp bot is not a second chatbot next to the one on your website. It is the same bot on another channel. It uses the same knowledge base, the same rules and the same handoff to your team. That is how we build it ourselves, and that is how it should be: otherwise you end up maintaining two versions of the truth.
- Answers from your content. Opening hours, prices, processes. If it isn't in the sources, the bot doesn't make it up.
- Voice messages. On WhatsApp, a lot of people talk instead of typing. The bot converts the message into text and answers it.
- Images. A photo of the nameplate or the error message often says more than three sentences.
- Selection lists and buttons. Instead of “Please type 1, 2 or 3”, the customer taps an appointment or “Yes, send”.
- Getting things done in the chat. Callback, appointment, ticket or inquiry: the bot asks for the missing details one at a time and creates the request.
- Handoff to people. When someone on your team takes over, the customer can see it. The reply from the inbox arrives back on WhatsApp, along with the conversation so far.
The two rules that decide everything
1. The 24-hour window
When a customer messages you, a 24-hour customer service window opens. Within it, the bot may reply in its own words as often as needed. Every new message from the customer restarts the 24 hours.
2. Outside the window, templates only
Once the window has closed, you may only send templates that Meta has approved in advance. Meta distinguishes three types: marketing, utility (such as an appointment confirmation) and authentication (such as a code). And you need the customer's consent to receive messages from you.
For a customer service bot, this means it almost always responds within the window, because the customer starts the conversation. Things get tricky at the handoff to your team. If an employee only replies after more than 24 hours, a free-form message can no longer go out. Then you need a template.
What it costs
Since July 1, 2025, Meta has billed per delivered message, no longer per conversation. Since October 1, 2026, the following also applies:
| Message | When | Cost |
|---|---|---|
| Service reply | within the 24-hour window | 1,000 per number and month free, charged after that |
| Utility template | within an open window | charged since October 1, 2026, free before that |
| Marketing, utility, authentication | any time, via template | always charged, price depends on country and type |
| Everything after a click on a Click-to-WhatsApp ad | up to 7 days | free |
| Messages from the customer to you | always | free |
Per-message prices are listed in Meta's price list for each country. For a sense of scale: provider overviews put Germany in 2026 at around 11 cents for a marketing template and around 4 to 5 cents for utility and authentication, each plus VAT. Meta's own price list is what counts. If your bot runs through an intermediary provider, their markup may be added on top.
Worked example
A business receives 400 inquiries a month via WhatsApp. On average, the bot sends four messages per conversation: answer, follow-up question, suggested appointment, confirmation. That's 1,600 service messages. 1,000 are free, 600 are charged. If you calculate conservatively with the utility rate of around 4.6 cents, that comes to just under €28 a month. Add 200 appointment reminders sent as templates, and it's a little over €9 more.
The lever isn't the price, it's the number of messages. A bot that sends every answer in three small pieces costs three times as much as one that answers in a single message. So when building the bot, it pays to bundle answers, avoid interim messages like “One moment” and attach buttons directly to the answer instead of sending them separately.
Data protection: what you should know
The WhatsApp Business Platform has its own data processing terms. Under them, WhatsApp Ireland acts as a processor on your behalf. Data may be transferred to Meta in the USA. For this, WhatsApp refers to standard contractual clauses and the EU-US Data Privacy Framework.
In practice, this means three things:
- Update your privacy policy. The WhatsApp channel belongs in it, with purpose, recipients and retention period.
- Redirect sensitive data. Health or account details don't belong in the chat. For these, the bot should send people to a form or to a person instead.
- Customer data only after verification. If someone wants to see their invoice or contract, the bot should first check that it is talking to the right customer, for example with a code sent to the email address on file.
Checklist before you launch
- Set up a Meta Business account and choose a dedicated number for the bot.
- Add a payment method. Since October, Meta no longer delivers service messages without a payment method once the 1,000 free messages are used up. The bot then replies into the void, and nobody notices.
- Get templates approved for everything you want to send outside the window, such as appointment reminders.
- Define the handoff. Who takes over when the bot gets stuck, and how quickly? Nobody should have to wait longer than 24 hours.
- Update your privacy policy and decide which topics the bot hands off to a form or to your team.
Frequently asked questions
Do I need the WhatsApp Business app?
No. A chatbot runs on the WhatsApp Business Platform, which is Meta's API. The Business app on your phone is a different product, meant for answering chats by hand.
What happens if no payment method is on file?
Since October 1, 2026, Meta then no longer delivers service messages once the month's 1,000 free messages are used up. The bot replies into the void.
Can the bot message customers after more than 24 hours?
Only with a template approved by Meta, and only if the customer has agreed to receive messages from you. Free-form replies are only possible within 24 hours of their last message.
Does the bot understand voice messages?
Yes, if it's built for it. The voice message is converted into text and then answered like a written question.
Where can I read up on the rules?
Billing and time limits are covered in Meta's pricing documentation for the WhatsApp Business Platform, data processing in the WhatsApp Business Data Processing Terms.
In short
- A WhatsApp bot should be the same bot as on your website: one knowledge base, one handoff, one inbox.
- It may reply freely for 24 hours after the customer's last message, and after that only with an approved template and consent.
- Since October 1, 2026, 1,000 service replies per number and month are free, and each one after that costs money.
- You control costs through the number of messages, not through the price.
- Without a payment method on file, the bot goes silent once the free allowance is used up.
