Since its launch, WhatsApp has become a key building block of digital customer journeys. But to make the most of its potential, you need to understand how messages are billed, particularly in Switzerland.
In January 2026, Meta introduced a major update to its message pricing. Here is a clear, up-to-date and practical explanation to help you run your WhatsApp usage effectively in 2026 and beyond.
Per-conversation pricing
Since January 2026, WhatsApp bills its services on a 24-hour window called a conversation.
A conversation opens when a template message is delivered, or when a user starts the dialogue. It is classified in one of four pricing categories:
- Service conversations: initiated by the user, covering support requests or post-purchase information. Since 1 November 2024 they have been free for all businesses, including with AI agents.
- Marketing conversations: initiated by the business, covering promotional offers and product recommendations. These are the most expensive messages.
- Utility conversations: order confirmations, shipping updates, appointment reminders.
- Authentication conversations: one-time codes to verify identity during logins or sensitive transactions.
| Type | Trigger | Typical use |
|---|---|---|
| Service | Customer → Business | Support, replying to a request, FAQs |
| Marketing | Business → Customer | Promotions, newsletters, product recommendations |
| Utility | Business → Customer | Order confirmation, appointment reminder |
| Authentication | Business → Customer | Sending a security code or OTP |
The free cases
- Service conversations are 100% free, even with an AI agent or a chatbot, within the 24-hour window.
- Conversations started from a click-to-WhatsApp ad get a free 72-hour window, whatever the message type.
- The first 1,000 service conversations each month are free, including via the API.

Per-message pricing from January 2026
On 1 January 2026, WhatsApp adopted a new pricing approach known as "per-message pricing", which applies to template messages sent outside a service conversation.
| Message concerned | Billed in 2026? |
|---|---|
| Marketing template | Yes |
| Utility template, outside a service window | Yes |
| Authentication template | Yes |
| Standard message inside the window | No, free |
| Utility template inside the service window | No, free |
Always free: replies within 24 hours of a user message, and messages from click-to-chat within 72 hours of the click.
