For almost two years, replying to customers on the WhatsApp Business Platform cost nothing. A customer messaged, you had 24 hours to reply as much as you liked, and Meta didn’t bill those messages. That ended on 1 October 2026.
If you use WhatsApp through an API provider (AiSensy, Interakt, Wati, Gupshup and so on), your invoice for October will look different. Here is what changed, what it costs at India rates, and what to do about it.
This applies to the WhatsApp Business Platform (the API). The free WhatsApp Business app on your phone is a separate product and is not affected.
The two changes that matter
Meta’s pricing update notes list several changes. Two of them hit small businesses directly.
1. Service messages are billed after a free tier. A service message is a normal, non-template reply sent inside the 24-hour window that opens when a customer messages you. Meta had made these free from 1 November 2024. From 1 October 2026, each business phone number gets 1,000 free delivered service messages a month, and every one after that is charged. Unused free messages do not roll over.
2. Utility templates sent inside the window are now charged. Order confirmations, appointment reminders and delivery updates are utility templates. Until September, a utility template sent while the customer’s 24-hour window was open was free. From October it is billed at the normal utility rate.
There is a quieter third change. If your account has no payment method, Meta will deliver service messages within the free tier and then stop delivering them. A business that never set up billing because “replies are free” could find its support replies silently failing in the last week of the month.
What it costs in India
Meta bills per delivered message, by category and by the country of the recipient’s number. India is its own market on the rate card. The India rates that WhatsApp providers publish from Meta’s card, before tax, are:
| Category | Rate per message (India) |
|---|---|
| Marketing template | ₹0.8631 |
| Utility template | ₹0.115 |
| Authentication template (OTP) | ₹0.115 |
| Service message (after 1,000 free) | ₹0.115 |
These are the figures listed by providers such as Watsberry, citing Meta’s rate card, and checked on 20 October 2026. Confirm the current numbers in WhatsApp Manager before you budget, since Meta updates rates during the year. Your provider adds GST and usually its own platform fee or markup on top.
Utility and authentication rates also drop at higher monthly volumes. Marketing does not get volume discounts.
A worked example
Take a hypothetical salon chain with one WhatsApp number. In a month it sends:
- 3,000 service replies to customers who messaged first
- 4,000 utility templates (booking confirmations and reminders)
- 2,000 marketing templates (a festive offer)
The Meta cost, before GST and provider fees:
- Service: 3,000 minus 1,000 free = 2,000 × ₹0.115 = ₹230
- Utility: 4,000 × ₹0.115 = ₹460
- Marketing: 2,000 × ₹0.8631 = ₹1,726
That is about ₹2,416 a month. Before October, the same month could have cost close to just the marketing line, because many of those utility reminders went out inside an open window and every service reply was free.
The example shows the real lesson. The new charges are small per message. Marketing broadcasts are still where most of the money goes.
Seven ways to keep the bill sensible
- Find out what you actually send. Ask your provider for October’s message count by category. Most owners have never seen this split.
- Stop sending three messages where one will do. “Thanks”, “Your booking is confirmed”, “Here’s the address” can be a single service reply. Every delivered message is now a line item once you cross the free tier.
- Use the free tier per number. The 1,000 free service messages apply to each business phone number. A business with separate numbers for two branches gets the allowance on each, though you should only split numbers if it makes sense for customers.
- Be choosy with marketing broadcasts. At roughly 7.5 times the utility rate, a blast to your full list should earn its cost. Send to people who bought or enquired recently, and check how many replies a campaign gets. Our lead cost calculator helps you decide what a reply is worth.
- Let customers start the conversation. When a customer comes in through a Click to WhatsApp ad or a Facebook Page button, Meta opens a free entry point window in which your replies are not charged. A plain WhatsApp link on your website also gets the customer to message first, which opens the service window.
- Check your provider’s markup. Some charge a flat monthly fee and pass Meta’s rates through. Others add a percentage on every message. The difference matters more now that more messages are billable.
- Migrate to INR billing before 31 December 2026. Meta’s pricing page says eligible India accounts must move all messaging accounts to INR by 31 December 2026, or messages from non-INR accounts stop being delivered from 1 January 2027. If your provider handles billing, ask them to confirm this in writing.
Should you still use the API?
For most businesses that get more than a few dozen WhatsApp enquiries a day, yes. The API gives you shared inboxes, automated replies, CRM sync and order updates that the phone app cannot. A few hundred rupees a month in service charges is small next to one lost enquiry.
What changes is the habit of treating WhatsApp as free. Every message now has a price, which is a good reason to make each one useful.
If you want help setting this up, our WhatsApp Business API marketing service covers templates, broadcasts and inbox setup. An AI customer support employee can also answer the repeat questions inside the service window, with one well-written reply instead of three.
