WhatsApp Business APIWhatsApp Business API pricing, explained for a support team
Meta bills the WhatsApp Business API per message since July 1, 2025, and the price depends on what kind of message it is. For a support team the news is good: replies to a customer who wrote to you are free inside the 24-hour service window. Here is how the model works, and what Sellio charges for WhatsApp, which is nothing.

How Meta's model works
Service replies are free
When a customer messages you, a 24-hour customer service window opens. Free-form replies inside it are not billed.
Utility inside the window is free too
Order updates and similar utility templates sent inside an open service window are free; outside it they are billed.
Marketing is always billed
Marketing templates are charged on every delivery, inside or outside a window. Support teams rarely send them.
Authentication
One-time-passcode templates are billed outside a service window and free inside it.
Free entry points
A conversation started from a Click-to-WhatsApp ad or a Facebook Page call-to-action opens a 72-hour window in which all messages are free.
What a support team actually pays
- Step 1
Inbound is free
Customers messaging you costs nothing. Replying within 24 hours costs nothing.
- Step 2
Re-opening costs a template
If you need to reach a customer more than 24 hours after their last message, you send an approved utility template, billed per message at your country's rate.
- Step 3
Sellio adds nothing
WhatsApp is a channel on every Sellio plan from Mini. You pay Meta for the API and Sellio for the workspace, with no per-message or per-conversation fee from Sellio.
