On July 1, 2026 Meta announced it will charge for service messages on the WhatsApp Business Platform. Billing starts October 1, 2026 and covers every reply your business sends from a platform connected to your number, whether written by someone on your team or by a bot. Through September 30, 2026 those replies remain free. Per-market rates have not been published yet; according to Meta's documentation, they are confirmed by September 1, 2026.
In this article you'll find what changes, what remains free to send, how to think about the impact on your account, and what you can do before October to contain the cost.
Note: September 2026 is when Meta publishes the official rates; billing only starts on October 1, 2026. Service messages are all messages that are not templates, in any format — text, image, audio, document or location — regardless of whether a person, a bot or an AI service sends them.
What changes on October 1, 2026
From that date, two things that are free today start being billed:
1. Service messages
A service message is any free-form reply — that is, not a template — that your business sends inside the 24-hour customer service window that opens when a customer writes to you. It includes text typed by a person from your inbox and text generated by a bot or AI solution connected to your number. From October, every delivered service message is billed individually.
2. Utility templates inside the 24-hour window
Today, replying with a utility template while the 24-hour window is open costs nothing. From October 1, 2026 it is also billed per message. The 24-hour window still exists as an operational concept — it defines what you can send without a template — but it stops being a free window.
Concept | Through 9/30/2026 | From 10/1/2026 |
Inbound customer message | Free | Free |
Free-form reply inside the 24-h window (human or bot) | Free | Billed per message |
Utility template inside the 24-h window | Free | Billed per message |
Utility or authentication template outside the window | Billed | Billed |
Marketing template | Always billed | Always billed |
Any message inside the 72-h Click to WhatsApp window | Free | Free |
Key dates
Date | What happens |
July 1, 2026 | Meta announces the change. Billing in Brazilian reais (BRL) begins for Brazil. |
September 1, 2026 | Meta's self-imposed deadline to publish the per-market rates effective October 1. |
September 30, 2026 | Last day when replying inside the 24-hour window is free. |
October 1, 2026 | Billing starts for service messages and for utility templates inside the 24-hour window. |
Note: Meta only changes prices on the first day of each quarter (January, April, July and October 1), with at least one month's notice for rate changes. After October, the next possible change window is January 1, 2027.
How billing works
Billed per delivered message, one by one
Not per conversation or session: every message that leaves your number and is delivered generates a charge. If your bot splits a reply into three bubbles, that's three billed messages. The charge happens on delivery, not on read: a delivered, unread message is billed all the same.
It doesn't matter who writes or sends
Billing doesn't distinguish between a person and a bot: if the message goes out through the platform connected to your number, it's billed. The only exception is a business that replies exclusively from the WhatsApp Business phone app, with no API or connected platform.
No volume discounts
Utility and authentication templates have volume tiers that lower the rate as monthly volume grows. Service messages don't get those tiers: the per-message rate is flat, whatever your monthly volume.
What the service message rate will be
Official per-country rates are published by Meta by September 1, 2026. Until then, no number is official: the only reliable source is the WhatsApp Business Platform pricing page in Meta's documentation:
The rate is determined by the recipient's country code, not by where your business is located.
Note for Brazil: since July 1, 2026 Meta bills Brazil in reais (BRL), with mandatory migration before June 30, 2027.
What remains free to send
Messages your customer sends you
Inbound traffic is never billed, no matter how many messages the person sends or through which channel they arrived.
The 72-hour free entry point window
When a customer starts the conversation from a Click to WhatsApp ad, a 72-hour window opens in which you can send any type of message with no delivery charge, including marketing templates.
What opens the 72-hour window: only ads that click to WhatsApp (shown on Facebook, Instagram or Messenger) and the call-to-action button of a Facebook page. Additionally, the customer must write to you from the WhatsApp app on Android or iOS, and you must reply within the first 24 hours — otherwise the window never activates.
What does NOT open the window: other Meta ads (those leading to a landing page, an instant form or an Instagram DM), floating WhatsApp buttons and widgets on your site (they work with wa.me links), QR codes, and numbers saved in contacts. In all those cases the 24-hour service window applies, which from October 1, 2026 is billed per message.
How to think about the impact on your account
Messages sent per month × your country's per-message rate = monthly cost
To get to "messages sent per month", multiply your monthly conversations by the average number of replies your operation sends in each one. That second factor is what usually surprises people: a bot that splits its replies into several bubbles multiplies the cost without changing the content.
Example — 500 conversations per month: with 5 replies per conversation that's 2,500 billed messages; with 3 replies, 1,500; with 2 replies, 1,000. Going from five replies to two per conversation cuts the cost by 60% without serving fewer customers: same service, fewer messages.
How to reduce the cost before October
Consolidate replies into a single message
The highest-impact lever and the fastest to apply. Every message you eliminate is a message you stop paying for, every month. This is already configurable in Darwin (single message mode, per channel).
Make the most of the 72-hour window from ad traffic
If part of your conversations starts from Click to WhatsApp ads, those 72 hours remain free for any message category. Concentrate lead qualification and follow-up there. Darwin shows you which conversations came in through an ad and how much free time remains before the window closes, with automatic follow-ups inside the window.
Qualify before investing replies
Through September, serving a curious browser costs nothing. From October, every reply is paid. Resolve early in the conversation whether the person has real intent, and save the long exchanges for those who move forward.
Replace back-and-forth with Meta Flows forms
When you need several pieces of customer data — name, address, dates — asking one by one costs a message per item. With WhatsApp Flows you collect everything in a single interaction. Darwin already lets you create and use Meta Flows from the product.
Audit your template categories
The difference between marketing and utility is large and varies by country. Periodically review whether each template's actual content legitimately qualifies for a lower-cost category in the markets where you concentrate traffic.
Consider alternative channels for low-value traffic
Instagram Direct and Messenger are not affected by this pricing change. For high-volume, low-value-per-contact inquiry flows, they can be an alternative with no per-message charge.
Frequently asked questions
Does this change apply to my business?
It applies if your WhatsApp is connected to the WhatsApp Business API, whether through a CRM, a bot or a service platform. It doesn't apply if you reply only from the WhatsApp Business phone app, with no integration.
Am I charged if the customer doesn't read the message?
The charge happens on message delivery, not on read. A delivered, unread message is billed all the same.
Does the 24-hour window disappear?
No. The window still defines when you can send free-form replies without using a template. What disappears is its being free.
Is this the first time Meta charges for these messages?
No. Service messages were billed until November 2024, when Meta made them free. The October 2026 change is a return to billing.
