What the WhatsApp Business Platform actually costs in India
Last updated: 2026-07-30
If you have asked three WhatsApp providers what messaging costs, you have three different numbers. None of them is necessarily lying. The confusion is structural: Meta changed how it bills twice in eighteen months, India moved to rupee billing partway through, and most published rate cards bundle Meta’s charge together with the provider’s own margin without saying which is which.
This page separates the two. It covers what Meta charges you and when, what is genuinely free, and what to ask a provider so their quote is comparable to anyone else’s.
The billing model changed in July 2025
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.
What is actually chargeable
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 it stays open for 24 hours from their most recent message. While it is open, ordinary messages — text, images, documents, anything that is not a template — are free, with no cap on how many.
| Message type | Inside an open 24-hour window | Outside the window |
|---|---|---|
| Ordinary (non-template) replies | Free, unlimited | Cannot be sent at all |
| Utility template (order updates, appointment reminders) | Free | Charged |
| Authentication template (OTPs) | Free | Charged |
| Marketing template (offers, re-engagement) | Charged | Charged |
Two consequences follow, and they drive most of the cost difference between businesses on the same rate card.
Inbound-led conversations are close to free. If a lead messages you first and you answer within 24 hours, the entire exchange — however long — costs nothing in Meta messaging fees. A business whose volume is genuinely inbound pays far less than its message count suggests.
Silence is what costs money. The moment a lead goes quiet for more than 24 hours, re-opening the conversation requires a template, and re-engagement templates are marketing-category. This is the single largest controllable line on a WhatsApp bill, and it is a function of how fast you reply, not how much you send.
Free entry points: the 72-hour window
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.
What changed for India
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.
Why every provider quotes a different number
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 published third-party numbers diverge for four reasons, and knowing which one applies turns two incomparable quotes into comparable ones:
- GST.18% applies to Meta’s messaging charges and to the provider’s platform fee. Some rate cards show it, most do not, and that alone is an 18% gap between two otherwise identical quotes.
- Staleness. Rate cards published before January 2026 predate both the currency switch and the marketing increase.
- Bundling. Many providers quote a single blended per-message price with their margin already inside it, so you cannot see what Meta charged and what the provider added.
- Category mix.A quote of “X per message” is meaningless without knowing the split between marketing and utility, which differ by roughly an order of magnitude.
What to ask a provider
Four questions make quotes comparable:
- Is your per-message price inclusive of GST, and inclusive of Meta’s charge?
- Do you mark up Meta’s conversation charges, or do you pass them through at cost and charge separately for the platform?
- What is your platform fee if I send zero messages in a month?
- What date is this rate card from?
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.
How this shapes what you should build
The pricing model rewards one behaviour above all others: answering fast enough that the conversation stays inside the free window. A business that replies to enquiries within minutes pays for very little; a business that replies the next morning pays a marketing-rate template to restart every conversation it let lapse — and, separately, loses most of those leads regardless of what the message costs.
That second cost is much larger than the first, and it is the subject of the research on lead response time.
