WhatsApp is about to start charging for replies inside the service window. Here is what changes.

From 1 October 2026, Meta begins charging for messages you send inside the 24-hour customer service window — including free-form replies from a human agent and utility messages sent in response to a customer. Those are free today. If your business handles support on WhatsApp, a category of message you have never paid for becomes billable.

It is not a rate rise. It is a change to what counts as chargeable, which is why it catches people who have been watching the rate card rather than the rules.

What is the 24-hour service window?

When a customer messages your business first, they open a 24-hour window. Inside it you can reply freely, without a pre-approved template, and the clock resets each time they send another message.

Until now that window has been the cheap part of WhatsApp. Business-initiated template messages — marketing, utility, authentication — carried a charge. Replies inside a customer-initiated window did not. That asymmetry is why WhatsApp has been an attractive support channel: the customer starts the conversation, and the conversation itself costs nothing.

From 1 October 2026 that stops being true.

What exactly becomes chargeable?

Message type	Today	From 1 October 2026
Marketing template	Charged	Charged
Utility template, business-initiated	Charged	Charged
Authentication template	Charged	Charged
Utility message sent inside the service window	Free	Charged
Free-form agent reply inside the service window	Free	Charged

Service messages are expected to be billed at the same rate Meta already applies to utility and authentication messages in that market, and — unlike utility and authentication — they are not expected to attract volume tier discounts.

Meta publishes current rates by market and category on its own pricing page, and they change. We deliberately do not reproduce them here, because a number copied onto a blog goes out of date quietly. Check Meta’s pricing page for the figures that apply to you.

Who does this actually affect?

Businesses running customer support on WhatsApp. The heaviest impact. A support conversation that took twelve back-and-forth messages cost nothing and will now cost twelve times a per-message rate. If your support volume is high and your conversations are long, this is a genuinely new cost line.

Anyone running an AI or automated agent on WhatsApp. Automated replies inside the window are messages like any other. A chatbot that responds three times where a human would have responded once has just become three times more expensive to run.

Businesses sending order and dispatch updates in response to a query. “Where is my order?” followed by a status update was free. It will not be.

Less affected: businesses whose WhatsApp use is mostly outbound campaigns. You were already paying per template message and nothing about that changes.

What should you do before October?

Measure your service window volume now. Most businesses have no idea how many messages they send inside customer-initiated windows, because it has never appeared on an invoice. Pull that number from your provider before the change, so you can size the impact rather than discover it.

Count messages per resolved conversation. If your average support thread runs to fifteen messages, ask why. Often it is three questions that could have been asked in one, or a bot that acknowledges before answering. Every unnecessary message is now a line item.

Audit your automations. Auto-acknowledgements, “thank you” messages, “is there anything else?” prompts — these were courtesy when free. Review each one and keep the ones that do work.

Check the ad-click exemption. Conversations that begin from an ad that clicks to WhatsApp, or from a Page call-to-action, carry a longer free window. If you advertise, routing enquiries through those entry points is worth understanding properly.

Do not panic-migrate off WhatsApp. The channel still reaches customers who ignore email and never install an app. This is a cost to manage, not a reason to leave.

Does this change whether WhatsApp is worth it?

For most businesses, no — but it changes how you should design the conversation.

Under the old model, more messages cost nothing, so systems were built to be chatty. Under the new one, the efficient conversation is also the cheap one, which pushes in the same direction as good service: answer completely the first time, ask for everything you need in one message, and stop sending messages that carry no information.

The businesses that will feel this most are the ones whose WhatsApp presence grew without anyone designing it. That is worth fixing regardless of the billing.

Common questions

Is the 24-hour window itself going away?

No. The window still governs when you may send free-form messages without a template. What changes is that sending them inside it is no longer free.

Are there still free service conversations?

Meta has provided a monthly allowance of free service conversations per WhatsApp Business Account under the current model. Whether and how that allowance carries into the new arrangement is the detail to confirm with your provider before October, because for a low-volume business it may cover most of the exposure.

Am I charged if a message is not delivered?

Meta bills on delivered messages. A message that fails to deliver is not charged — though a poor quality rating increases the share of messages that never complete delivery, which reduces reach without reducing your provider’s platform fees.

Does moving support to a chatbot reduce the cost?

Only if the bot resolves in fewer messages than a person would. A bot that sends four messages to a human agent’s one has increased both the cost and the customer’s irritation. Measure messages per resolved conversation, not conversations handled.

Where do I find the rate that applies to my market?

Meta’s own pricing page, which is the only source worth relying on. Rates vary by recipient country — billing follows the recipient’s country code, not where your business is registered — and they are revised periodically.
