Written by the CustomerEagle team
For almost two years, replying to a customer on WhatsApp cost a business nothing: Meta made service conversations free on 1 November 2024. That ended on 1 October 2026. Replies inside the 24-hour customer service window are billable again once a phone number has used its monthly free tier. This article sets out what Meta's own documentation says, what a support team should count, and how to keep the bill predictable. It quotes no per-message rates, because they differ per country and Meta can change them every quarter.
How WhatsApp Business API pricing works
Meta moved from per-conversation to per-message pricing on 1 July 2025. A business is charged only when a message is delivered, and the rate depends on two things: the message category and the market of the recipient's phone number. Template messages (marketing, utility and authentication) can be sent at any time. Free-form replies, which Meta calls service messages, can only be sent while a customer service window is open: a 24-hour timer that starts when the customer messages or calls you and restarts when they write again.
| Category | When you can send it | Billing since 1 October 2026 |
|---|---|---|
| Service (free-form reply) | Only inside an open 24-hour customer service window | 1,000 delivered messages free per phone number per month, then charged per message |
| Utility template | Any time | Charged per delivered message, including inside an open window |
| Authentication template | Any time | Charged per delivered message |
| Marketing template | Any time | Charged per delivered message |
| Messages from the customer | Any time | Free |

What changed on 1 October 2026
- Service messages are billable again. Each business phone number has one free tier of 1,000 delivered service messages per month. Meta charges from the 1,001st message, and the unused part of the tier does not carry over to the next month.
- A payment method is now required to keep replying. Meta delivers service messages within the free tier, but without a payment method on file it does not deliver them once the tier is used up.
- Utility templates inside the window are no longer free. They had been free in an open customer service window since 1 July 2025; that exception ended on 1 October 2026.
- Rate cards moved. Meta lists rate changes for that date, including markets that left a regional group and now have a rate of their own. Check the current card for the countries your customers are in.
- Eligible governments and non-profits keep free service messages beyond the free tier through 31 December 2027.
What stays free
Three things. Messages your customers send you are free. The first 1,000 delivered service messages per phone number each month are free. And when a customer starts the chat from a Click to WhatsApp ad on Android or iOS and you answer inside the customer service window, a free entry point window opens in which Meta does not charge for marketing, utility, authentication or service messages; Meta's documentation says that window may remain open for up to 7 days.
What a support team should count
The unit is the delivered message, not the conversation. That changes the estimate. A team that handles 400 WhatsApp conversations a month and sends six replies in each delivers 2,400 service messages: 1,000 fall in the free tier and 1,400 are billable at the rate for each customer's country. The same 400 conversations answered in three replies each deliver 1,200 messages, of which 200 are billable. Reply count per conversation is now a cost driver, which it was not before October.
Replies written by an AI agent are sent as service messages as well, so they draw on the same free tier as replies your agents type. If you are planning AI on this channel, the rollout checks in WhatsApp AI support: an operational readiness guide still apply; add a message budget to them.
Five ways to keep the cost predictable
- Pull your real numbers first. Export one month of WhatsApp conversations and count the business replies per phone number. Most teams have never needed this figure.
- Answer completely in one message. One reply with the answer, the condition and the next step costs a third of three short ones.
- Add the payment method before you need it. Without one, replies stop being delivered when the free tier runs out, mid-month and mid-conversation.
- Move confirmations into the conversation where you can. A shipping update the customer asked for inside the window can be a free-form reply; a template sent later is always billed.
- Review the rate card each quarter. Meta can change rates on the first day of January, April, July and October.
Where CustomerEagle fits
CustomerEagle connects through the official WhatsApp Business API and is included from the Professional plan. Meta's message charges are not marked up or resold: Meta bills them directly to your WhatsApp Business Account, so the invoice you check is Meta's own. WhatsApp conversations land in the same inbox as web chat and email, and Eagle AI answers from the same approved knowledge on each channel. Set-up and plan details are on the WhatsApp integration page; seat prices are on the pricing page.
Frequently asked questions
Partly. Since 1 October 2026 each business phone number gets 1,000 free delivered service messages per month. Meta charges per message from the 1,001st, and unused free messages do not roll over to the next month.
No. The charges described here apply to the WhatsApp Business Platform, the API that help desks and automation tools connect to. A business that only replies from the WhatsApp Business app on a phone does not pay Meta per message.
Meta still delivers service messages inside the free tier of 1,000 per phone number per month. Once that tier is used, service messages are not delivered until a payment method is added to the WhatsApp Business Account.
It depends on the country of the customer's phone number. Meta publishes the rates per category and market in the rate card linked from its pricing documentation, and it can change them on 1 January, 1 April, 1 July or 1 October.
A free-form reply inside the customer service window is a service message whether an agent or an AI agent wrote it. Both count toward the same monthly free tier and are billed the same way after it.
