From 1 October, replying to a customer on the WhatsApp Business Platform will cost you money. Free-form service messages sent inside the 24-hour customer service window have been free since November 2024. Meta confirmed in July that they will become billable per message, charged at the same rate as a utility template in the recipient's country.

It applies whether the reply comes from a human agent, your own chatbot or a third-party AI tool.

Two details matter more than the headline. There is no volume discount on service messages, so a business sending 50,000 replies a month pays 50,000 times the rate rather than a tiered bulk price. And utility templates sent inside that window, free since July 2025, start carrying charges again on the same date.

Only the Cloud API is affected, so the free WhatsApp Business app and WhatsApp Web stay free, which is a reprieve for the smallest operators rather than a strategy for anyone growing. Meta publishes country rates by 1 September, leaving one month to model the impact.

Separately, Meta's own Business Agent moved to token billing on 1 August at $2 per million tokens, roughly four to five cents a message. Conversations opened from a click-to-WhatsApp ad keep their free 72-hour window.

Hypertext reported the change via Helm, a local AI and customer experience company, whose chief solutions officer Arno van Huyssteen argues service conversations on WhatsApp still run roughly four times cheaper than the same volume through a call centre, and that October narrows the gap rather than closing it. TechTimes notes the practical effect is that no reply inside an open conversation remains free. Wati, a Meta solution provider, points out that authentication templates were always charged in-window.

Free was never a feature. It was customer acquisition, and it worked. SA businesses moved support onto WhatsApp because the marginal cost of a reply was zero, and the rate card arrives now that the behaviour is locked in.

The businesses that feel it hardest are the ones whose volume is mostly inbound questions rather than outbound sales, so clinics, property managers, delivery operations and anyone running a service desk.

Two moves before October. Model your volume against the rate card the day it publishes, and consolidate replies that your workflows currently split across two or three messages, because each one is now a separate line item.
