Most providers avoid this conversation until after you have signed. Here is the whole picture, including the parts that are not in Meta's rate card.
Meta stopped charging per 24-hour conversation on 1 July 2025 and now bills per delivered message, in four categories. India moved to rupee billing in January 2026. The indicative Meta rates are roughly ₹0.8631 for a marketing message and ₹0.115 for a utility or authentication message. Since 1 October 2026, service messages (your replies inside a customer-initiated chat) are charged too, at about ₹0.115 each after 1,000 free per business number each month, and utility templates sent inside an open service window are no longer free. On top of Meta's charge you pay 18% GST and your provider's platform fee. Utility and authentication rates fall as monthly volume grows.
| Category | Indicative Meta rate | Typical use | How to spend less on it |
|---|---|---|---|
| Marketing | ₹0.8631/ message | Offers, launches, festival campaigns, re-engagement | Segment hard. A message to a list that will not convert costs the same as one that will. |
| Utility | ₹0.115/ message | Order confirmations, dispatch and payment updates, reminders | Charged even inside an open service window since 1 Oct 2026. Combine updates into one message where you can. |
| Authentication | ₹0.115/ message | Login OTPs and verification codes | Volume tiers reduce this as monthly traffic grows. |
| Service | 1,000 free/ number / month | Your replies within a chat the customer started | Charged per message beyond the monthly free tier since 1 Oct 2026. Resolve chats in fewer, fuller replies. |
Rates are set by Meta, exclude 18% GST and our platform fee, and change periodically — we confirm the live rate card before you launch. A fuller walkthrough with worked examples is in our guide to WhatsApp Business API pricing in India.
A Coimbatore retailer sending 5,000 order updates, 2,000 OTPs and one 8,000-contact festival campaign in a month is looking at roughly ₹805 of utility and authentication traffic and about ₹6,905 of marketing — under ₹8,000 of Meta charges before GST and platform fee.
Move even half those order updates inside an open service window and the utility line drops toward zero. That is the kind of restructuring we do during onboarding, and it is usually worth more than negotiating the platform fee.
WhatsApp is not automatically cheaper. An authentication message at ₹0.115 competes closely with a transactional SMS, and SMS needs no app, no internet and no prior opt-in — which is why banks still send OTPs both ways.
Because we run the SMS gateway too, we will tell you when SMS is the better channel for a given flow, and set up automatic fallback to it when a WhatsApp message cannot be delivered.
Most of your customers read Tamil first. Every message that starts a conversation must use a template Meta has approved, and the Tamil version is approved as its own entry under the same template name. Three we set up often for Coimbatore shops, distributors and service firms:

A retail chain with several stores around Coimbatore was answering order questions, delivery queries and returns from one personal WhatsApp number. We moved it to the official API with order notifications, an FAQ chatbot for routine questions and a shared team inbox, so staff stopped copying and pasting replies. Read the case study →
