WhatsApp Chatbot Pricing: The Per-Message Model Explained
Most WhatsApp pricing guides are out of date. Meta moved from per-conversation to per-message billing on 1 July 2025, and the old free allowance of 1,000 service conversations is gone.
Prices verified 18 July 2026. Vendors change pricing often, so every figure links to its source.
If a guide tells you WhatsApp bills per 24-hour conversation window and gives you 1,000 free service conversations a month, it is describing a model Meta retired. Per Meta's own pricing documentation: "Effective July 1, 2025, Meta charges on a per-message basis", and charges apply "when a template message is delivered".
That single change rewrites the budgeting maths, because what you pay for is now template messages sent, not conversations opened. It also means a lot of what is free is defined by whether a customer service window is open.
How Meta bills WhatsApp now
You are charged when a template message is delivered. Category determines whether it is billable, and the customer service window determines whether it is free.
| Message type | Billing | Notes |
|---|---|---|
| Marketing template | Charged | Promotional sends are always billable |
| Utility template | Charged outside an open service window | Free when delivered inside an open customer service window |
| Authentication template | Charged outside an open service window | Used for OTPs and verification |
| Any non-template message | Free inside an open service window | Your normal back-and-forth replies |
| Free Entry Point traffic | Free for 72 hours | User-initiated via ads or a Page button |
| Monthly free allowance | None stated | The old 1,000 free service conversations no longer applies |
Rates vary by country and by category, and Meta applies volume-based discounts on utility and authentication messages. We are not reproducing a country rate card here because those change frequently; read the current numbers on Meta's pricing page for the countries you actually message.
The three bills behind a WhatsApp chatbot
WhatsApp chatbot pricing is not one invoice. It is Meta, plus a provider, plus your chatbot software.
1. Meta message fees
Charged per delivered template message, as above. This is the layer that scales with how much outbound you send, and the one you control by sending fewer, better-timed templates.
2. Business Solution Provider (BSP) fees
You reach the WhatsApp Business Platform through a provider such as Twilio, 360dialog, MessageBird or similar. Some charge a monthly platform fee, some add a per-message markup, some bundle Meta's fees into one rate. Pricing models differ enough that we are not quoting figures we have not verified; get a written quote at your expected volume and ask specifically whether Meta's fees are included or passed through.
3. The chatbot platform
The AI software that actually answers. matram.ai is flat monthly at $29, $69 or $199 with unlimited team seats, and a 7-day free trial with no credit card. There is no per-message or per-resolution charge on our side, so the variable part of your WhatsApp bill comes from Meta and your BSP, not from us.
How to keep WhatsApp costs down
Under per-message billing, the levers are which category you send and whether the service window is open.
- Answer inside the open customer service window, where non-template messages are free.
- Prefer utility templates over marketing templates where the message genuinely is transactional.
- Use Free Entry Point traffic (click-to-WhatsApp ads, Page buttons), which opens a 72-hour free window.
- Resolve in fewer sends: a bot that answers correctly first time costs less than one that needs three follow-ups.
- Check whether volume-based discounts on utility and authentication apply at your send volume.
- Ask your BSP whether Meta fees are bundled or passed through, so you are not surprised by two invoices.
Where matram.ai fits today
Being straight about status: matram.ai's WhatsApp channel is on the roadmap, not live.
We are not going to sell you a WhatsApp integration we have not shipped. Today matram.ai deploys to your website widget plus Slack, Facebook Messenger, Crisp, Freshchat, Zendesk, Zoho SalesIQ and Google Chat. WhatsApp and HubSpot are marked coming soon.
If WhatsApp is your primary channel right now, use this page to budget Meta and BSP costs correctly, and pick a platform that supports it today. If your priority is the website and the channels above, the integrations overview lists what is live, and the Messenger integration covers the Meta channel we do support.
