WhatsApp starts charging for service messages on 1 October 2026
From 1 October 2026, Meta charges for every message your business sends as a reply inside WhatsApp's 24-hour customer service window, which has been free since November 2024. If your WhatsApp account has no payment method on file by 30 September, your replies stop being delivered on 1 October; check with your provider today. On the same day, utility templates sent inside that window, free since 1 July 2025, start being charged too. It affects any business that serves customers through the WhatsApp Business Platform (the API), whether a team, a chatbot or an AI assistant does the replying.
What a service message is
When a customer messages you on WhatsApp, a 24-hour customer service window opens. Inside that window your business can reply with ordinary messages, no approved template needed. Meta calls those replies service messages. Until now they were free. According to Meta's documentation on non-template messages, from 1 October 2026 they are charged per message, the same way templates already were.
"Any non-template message is charged as of October 1, 2026."
Meta, pricing for non-template messages
Meta adds three details. In each market, a service message costs the same as a utility or authentication message. There are no volume tiers for service messages. And only one charge applies per message. Meta also says the charges are for delivered messages: you pay for messages that are delivered, not for every message sent.
Here is how a typical conversation now looks. The customer's messages carry no charge. Every message the business sends does.
Until 30 September, this conversation cost nothing. From 1 October it creates three charges: two service messages and one utility template, all at your market's utility rate. The exception Meta keeps: if the customer arrived from a Click to WhatsApp ad or a Facebook call-to-action button, messages sent inside the 72-hour free entry point window remain free for message delivery.
What it means for a small business
The cost no longer depends on how many customers write to you, but on how many messages you send to serve them. A chatbot that answers in five short messages what it could say in two costs more than twice as much. The same goes for a team that replies "one moment" before giving the real answer.
An example with round, hypothetical numbers, worked out on 27 September 2026. A shop in Spain handles 500 conversations a month and its assistant sends an average of six replies per conversation: 3,000 messages. In Meta's rate card in euros effective 1 July 2026, the utility rate for Spain is 0.0166 euros per message (0.0200 US dollars in the USD card). That comes to about 50 euros a month in Meta charges alone. If the same assistant resolves each conversation in three replies, it is about 25 euros.
That will not sink anyone, but it is a new cost that grows with every extra message. Before relying on the example, check the rate in force for your market in Meta's rate card on the day you do the sums.
Replies per conversation × conversations per month × utility rate for your market
- Plus your WhatsApp provider's (BSP) markup, per message or as a fee.
- Plus, if you use an AI assistant, the model cost for each message it writes.
What to do before the first invoice
- Fewer, fuller replies. Put in one message what today takes three. Drop the "one moment, let me check" messages that add nothing.
- Resolve in fewer turns. If the assistant asks for details one at a time, have it ask for them all at once. If it has the information, have it answer instead of asking.
- Ask your provider. Check that your BSP passes Meta's price through as it is, and what it adds on top, per message or as a fee.
- Watch the October invoice. It is the first with service messages on it. Compare it with your estimate and see which conversations produce the most messages.
Custom assistant or Meta Business Agent
Meta charges differently depending on who writes the reply. If a person or a third-party AI replies, each message is charged as a service message, and the AI provider bills you for the model separately. If Meta Business Agent, Meta's own AI agent, replies, it has been charged per token since 1 August 2026: 2 US dollars per million tokens, with about 20,000 to 25,000 tokens per message according to Meta, which is roughly 4 to 5 US cents per message. Because only one charge applies per message, that message does not also pay the service rate.
Which works out cheaper depends on how many messages each conversation needs and what the model you use costs. We compare the two in more detail in Meta Business Agent vs a custom WhatsApp assistant.
