WhatsApp Business API Pricing 2026: Per-Message Rates and the 1 October Change

Updated 30 September 2026. From 1 October 2026 Meta charges for WhatsApp service messages, the replies you send inside a customer’s 24-hour window, after the first 1,000 each month per phone number. This guide explains the whole 2026 pricing model, works through a real month, and shows how to keep the bill down.

WhatsApp Business API pricing is two bills from two companies. Meta charges per message, at a rate set by the message category and your customer’s country. Your software provider charges a subscription for the inbox, the chatbot and everything else on top. Most pricing pages blend the two, which is why a support lead gets surprised three months in. This page keeps them apart.

Key takeaways

• Meta bills per message, not per conversation. That has been true since 1 July 2025.
• From 1 October 2026, service replies cost money after 1,000 free per phone number per month, at the utility rate for the customer’s country. The allowance resets monthly and does not roll over.
• You need a payment method on your WhatsApp Business account. Without one, Meta stops delivering service messages once they become charged.
• Utility templates are still free inside an open 24-hour window. Marketing templates are charged every time, at the highest rate.
• Your software subscription is separate. On Tendabot it is $29, $99 or $299 a month with AI replies included, and we add nothing to Meta’s fees.

What changed on 1 October 2026

From November 2024 until 30 September 2026, every free-form reply inside the 24-hour customer service window was free. That made WhatsApp support cheap: a customer wrote, you answered as often as you liked, and Meta charged nothing.

From 1 October 2026 those replies, which Meta calls service messages, are charged per message at the same rate Meta charges for utility templates in that market. Every business phone number gets 1,000 service messages free each month. Meta charges from the 1,001st, the count resets on the first of the month, and unused messages do not carry over.

The deadline that matters: if your WhatsApp Business account has no payment method on file, Meta stops delivering service messages once they become charged. For a business that sends more than 1,000 replies a month, that means customers stop getting answers partway through the month. Add a card in WhatsApp Manager under payment settings. It takes two minutes.

How Meta bills WhatsApp in 2026

Every message you send falls into one of four categories. The category decides whether you pay and how much.

Category	What it is	What Meta charges
Service	A free-form reply inside the 24-hour window after the customer’s last message	First 1,000 per number per month free, then the utility rate for the customer’s country
Utility	A template about something the customer asked for: order confirmed, shipped, appointment reminder	Free inside an open 24-hour window. Charged outside it
Authentication	One-time passwords and login codes	Charged per message
Marketing	Offers, announcements, anything promotional, including broadcasts	Charged per message, at the highest rate

Rates depend on the country code of the person you are messaging, not where your business is. The spread is wide: utility and service rates run from well under a tenth of a cent in some markets to around five cents in parts of Western Europe, and marketing costs several times more than utility in most places. Always check Meta’s current rate card for the countries you actually sell to. Rates change a few times a year.

One more rule worth knowing: when a customer messages you from a click-to-WhatsApp ad or a Facebook Page call-to-action, a 72-hour free entry window opens, and messages inside it are free. That makes ad-driven chats cheaper than they look.

The second bill: your software

Meta only provides the pipe. To answer customers you need something on top: an inbox for your team, a chatbot or AI, templates, broadcasts, contacts. That is what platforms like Tendabot, Wati, AiSensy or Respond.io charge for.

There are three ways platforms charge, and it pays to know which one you are looking at:

• A subscription for the software, usually by plan and number of seats.
• A markup on Meta’s messages. Some providers resell Meta’s messages at their own rate card rather than letting Meta bill you. Independent comparisons have reported markups of around 20% on some platforms. Ask directly: does Meta bill my WhatsApp Business account, or do you?
• AI as an add-on. Many platforms sell the AI agent separately from the plan. Check whether “chatbot” in the plan means a flow builder or an AI that actually answers questions.

Tendabot charges a subscription only. Meta bills your own WhatsApp Business account directly for every message, and AI replies are included in the plan. You can compare platforms side by side on our pricing comparison page.

A real month, worked through

Take an online homeware shop in the UK that uses WhatsApp for customer service and order updates. In a typical month:

• 600 customers start a chat. On average the shop sends three replies each: 1,800 service messages.
• It sends a shipping update for 400 orders. About half go out while the customer’s window is still open, so 200 utility templates are charged.
• It sends one broadcast about a sale to 1,000 opted-in customers: 1,000 marketing messages.

For the maths, suppose the UK service and utility rate is $0.02 per message and the marketing rate is $0.05. Those are round numbers for illustration, not Meta’s rate card, so swap in the real rates for your countries.

Line	Messages	Free	Charged	Cost
Service replies	1,800	1,000	800	$16.00
Utility templates outside the window	200	0	200	$4.00
Marketing broadcast	1,000	0	1,000	$50.00
Meta total				$70.00

Then the software. If Tendabot’s AI writes 1,500 of those 1,800 replies and the team types the rest, the shop needs Pro at $99 a month, which includes 3,000 AI replies. Replies typed by a person never count against the allowance. So the month costs about $99 for Tendabot plus $70 paid to Meta, and the two show up as two separate invoices.

Before 1 October the service line would have been $0. That is the change in one number: for a business sending about 2,000 replies a month, service replies now cost roughly the price of a small subscription.

Six ways to keep the Meta bill down

1. Answer a burst with one reply. Customers send three short messages instead of one. If your system answers each line, you pay three times. Tendabot can wait a few seconds for the customer to finish, then answer everything in a single reply. See auto replies.
2. Stop replying to “ok thanks”. A polite bot that answers every thank-you with another message doubles the count at the end of each chat. Tendabot does not reply to a closing “okay” or thumbs-up when nothing was asked.
3. Send order updates while the window is open. A shipping template sent within 24 hours of the customer’s last message is free. Sent a day later, it is charged.
4. Use click-to-WhatsApp ads for acquisition. The 72-hour free entry window covers the whole first conversation.
5. Segment broadcasts. Marketing is the most expensive category. Sending to people who bought in the last 90 days instead of your whole list cuts the bill and the opt-outs. Tendabot shows reach and cost before anything is sent. See WhatsApp broadcasts.
6. Keep a payment method on file. It will not save money, but it stops the worst case: replies silently not arriving once you pass 1,000 in a month.

What Tendabot costs

• Starter, $29 a month: 500 AI replies, 3 seats, 1 WhatsApp number.
• Pro, $99 a month: 3,000 AI replies, 10 seats, 3 numbers.
• Scale, $299 a month: 15,000 AI replies, 50 seats, 10 numbers.

AI is included on every plan. Meta bills your WhatsApp Business account directly with no markup from us. With WhatsApp Coexistence you keep using the WhatsApp Business app on the same number. Full details are on the pricing page, and you can see how the AI works on the WhatsApp chatbot page.

Frequently asked questions

Is the WhatsApp Business API free?

Access is free, but messages are not. Since 1 October 2026 Meta charges service replies after the first 1,000 a month per number, and it always charged marketing, authentication and utility templates sent outside the 24-hour window. Your software provider charges separately.

How much does a WhatsApp message cost?

It depends on the category and the recipient’s country. Utility and service messages cost from well under a tenth of a cent to a few cents; marketing costs several times more. Check Meta’s current rate card for your markets.

Are messages from the WhatsApp Business app charged?

The app itself stays free. The charges on this page apply to messages sent through the WhatsApp Business Platform, the API that tools like Tendabot use.

What happens if I do not add a payment method?

Meta stops delivering service messages once they become charged. In practice, your first 1,000 replies each month go out and the rest do not.

Do replies my team types by hand count?

For Meta, yes: every service message counts toward the 1,000 and is charged beyond it, whoever wrote it. For Tendabot’s plan allowance, no: only AI replies count.
