What the WhatsApp Business Platform actually costs in India

Meta has announced that from 1 October 2026 it will charge for two things this page describes as free: service messages — the ordinary, non-template replies you send inside an open 24-hour window — and utility templates sent in response to a user inside that window. The rates take effect on that date and Meta has said it will publish them by 1 September 2026.

The 24-hour window itself is unchanged, inbound stays free, and the 72-hour Click-to-WhatsApp free entry window is explicitly unchanged. But the sentence that summarises the current model — you pay to start a conversation, not to have one — stops being true.

We have kept this page describing the model in force today, because it is the one you are billed under until October, and marked the two rows that change. The full before-and-after, and what it means for a business running paid acquisition into WhatsApp, is in the note on the October 2026 pricing changes.

Until mid-2025, WhatsApp billed per conversation: a 24-hour session, opened by a template, charged once regardless of how many messages passed through it. That model is gone. Since 1 July 2025, Meta bills per message delivered, and only template messages are chargeable.

This matters more than it sounds. Under conversation billing, a long back-and-forth cost the same as a single message. Under per-message billing, cost scales with the number of templates you send — so a follow-up sequence that fires five templates at a cold lead now costs five times what one does, where previously it may have cost nothing extra.

There are three template categories, and they are not treated the same way. The distinction that governs your bill is not the category on its own, but whether a customer service window is open. That window opens when a user messages your business and stays open for 24 hours from their most recent message. While it is open, ordinary messages are free, with no cap on how many — until 1 October 2026.

There is one meaningful exception. When a user reaches you through a Click-to-WhatsApp ad or a WhatsApp button on a Facebook Page, your first reply opens a 72-hour free window rather than a 24-hour one, and within it every message type is free — including templates.

For anyone running paid acquisition into WhatsApp, this changes the arithmetic of the ad itself: the messaging cost of a lead from a Click-to-WhatsApp ad is nil for three days, which is longer than most qualification conversations need.

India moved to local currency billing on 1 January 2026. Businesses billed in other currencies are expected to migrate their accounts to INR, and Meta has published a deadline of 31 December 2026 for that migration, with conversion APIs provided during 2026.

The switch was not purely cosmetic. India’s marketing rate rose at the same time, and a further increase to international authentication rates followed on 1 April 2026. If you are working from a rate card compiled before 2026, it is wrong in a direction that costs you money.

We are deliberately not printing a per-message rupee figure on this page. Rates have moved three times in eighteen months, and a stale number stated confidently is worse than no number. Meta publishes the authoritative rate card in its developer documentation, and that is the figure to price against.

The second question is worth pressing on. Meta’s own partner terms restrict Tech Providers from marking up conversation fees, so a provider whose margin is buried inside a blended per-message rate is either not a Tech Provider or is not being straight about where the margin sits. Neither is disqualifying, but you should know which you are buying.

The pricing model rewards one behaviour above all others: answering fast enough that the conversation stays inside the free window. That second cost — the leads lost while the window lapsed — is much larger than the first, and it is the subject of the research on lead response time.
