Meta will start charging South African businesses for the replies they send customers on WhatsApp from 1 October, ending an exemption that has made customer service on the platform free since November 2024 – but with six weeks to go, it has not said what those replies will cost.

The charge applies to service messages on the WhatsApp Business Platform: the free-form replies a support agent or a chatbot sends inside the 24-hour window that opens when a customer messages first. It bites at platform level, hitting every business on the application programming interface, whichever provider sits in between, and there is no opt-out.

Meta has committed to publishing per-market rates by 1 September, a month before it starts billing. Until that happens, the service column on its rate card reads “n/a”, and every figure in circulation – including the 12c/message doing the rounds locally – is an industry estimate reverse-engineered from what utility and authentication templates cost today.

WhatsApp is not a marketing sideline for South African banks, insurers and mobile operators – it is a primary service desk. Absa has run full banking services inside the app since 2024, and there is even a WhatsApp-managed bank card on the market locally.

Meta has illustrated the shift: a single hour-long exchange that opens with a marketing message, moves through automated replies and a handover to a human agent, and closes with an order confirmation. Today that produces one billable message. From 1 October, by Meta’s own count, the same exchange will produce five charges.

Johannesburg customer experience firm Helm, which runs WhatsApp channels for DStv, Absa, Telkom, Capitec and MTN, has done the local arithmetic to give clients something to plan against. Its working estimate is 10c to 15c/message, built on current utility and authentication pricing converted at about R16.80/US$, roughly July’s rate. The rand has since firmed to about R16.21.

Enormous numbers

A retail order query can easily run to half a dozen replies. A fintech or insurance interaction, a know-your-customer check, a claim, an account dispute, can run longer and have more steps. Telecommunications queries are short but arrive in enormous numbers. In each case, the cost is a function of how many times the business has to reply, and a support conversation is nothing but replies.

Arno van Huyssteen, Helm’s chief solutions officer, argues the channel still wins on cost even after October, though the firm has an obvious interest in customers staying on it. “It’s easy to read this as WhatsApp getting more expensive, full stop,” he said. “But even with the new fees, customer service conversations on WhatsApp still cost around four times less than running the same volume through a traditional call centre. That gap doesn’t close in October, it just narrows slightly.

He said “it’s clear” businesses “need to start adjusting their message flows now in order to lessen that impact”.

The standard advice when WhatsApp gets more expensive is to move traffic into templates, which are billed but predictable.

But solution providers tracking Meta’s documentation have warned that utility templates sent in reply to a customer inside the same 24-hour window, free since July 2025, also become billable on 1 October. So, the obvious dodge, to reclassify the reply as a utility template, no longer escapes the charge if it happens inside the service window.

Template routing still helps where a message genuinely belongs in a template and can be sent outside the window, but the blanket version of the tip does not survive the change.

There is one door that stays open: a conversation that starts from a Facebook or Instagram click-to-WhatsApp ad opens a 72-hour free messaging window the October change leaves alone, which effectively lets a business use paid advertising to buy a stretch of free support capacity.

Even that carries an asterisk, though: businesses using Meta’s own Business Agent are charged for the tokens it burns inside that window, a charge that began on 1 August at $2 per million tokens, or roughly four to five US cents a reply. That token meter is a third way to be billed for a reply, alongside the per-message service charge and the utility template, and it scales with how complicated the answer is rather than how many messages it takes.

For ordinary WhatsApp users, nothing changes. Meta has said it does not intend to charge for messaging or core features, and its consumer monetisation in South Africa has so far run through cosmetic extras such as the R28.99/month WhatsApp Plus tier that launched locally in June.
