Your WhatsApp bill has three layers, and most pricing pages show you only one of them. The first layer is Meta: on the rate card effective 1 October 2026, a delivered message to an Indian number costs Rs 0.8631 for marketing and Rs 0.1150 each for utility, authentication and service. The second layer is your provider, the software company whose inbox and automation you use, charged as a monthly plan, a markup per message, or both. The third layer is 18% GST, applied on top. As of November 2026, budget with all three layers or your first invoice will surprise you.
The short version: Meta's India rate card
These are Meta's list rates per delivered message, before provider charges and GST. The rate follows the recipient's country, so this card applies to messages delivered to Indian (+91) numbers.
| Category | Per delivered message | When you use it |
|---|---|---|
| Marketing | Rs 0.8631 | Offers, promotions, broadcast campaigns, cart and re engagement messages |
| Utility | Rs 0.1150 | Order confirmations, dispatch and delivery updates, statements, service notices |
| Authentication | Rs 0.1150 | OTPs and login verification codes |
| Service | Rs 0.1150 | Free form replies inside the 24 hour service window, after the free tier below |
| Authentication international | Rs 2.4971 | A narrow rate for large senders based outside India sending OTPs to Indian numbers. It is not the rate an India based business pays |
Source for the card: Meta, WhatsApp Business Platform pricing, rate card effective 1 October 2026. Check the live card on Meta's pricing page before you commit a budget, because Meta changes rates only on quarter starts: 1 January, 1 April, 1 July and 1 October. The next possible change after this card is 1 January 2027.
Two numbers from this table drive every buying decision. Marketing costs about seven and a half times the utility rate, so the category of a template is a pricing decision, not a labelling detail. And service messages, which were free for a long period, are now charged, which changes the cost of running a support heavy number.
How billing actually works
Per message, not per conversation. Since 1 July 2025, Meta charges per message. Older guides that quote a per conversation price, or say the first 1,000 conversations across all categories are free, describe a billing model that no longer exists.
You pay on delivery. A template message that is delivered is charged. A message that fails is not. Inbound messages from customers are free: you are not charged because a customer wrote to you.
The template category sets the price. A marketing template costs the marketing rate even if you send it to an existing customer. A utility template must genuinely be a utility message, tied to a transaction or an account the customer already has with you. Meta reviews template categories, and a promotional message dressed as utility is both a pricing risk and an account quality risk.
There is no licence fee for the API itself. Access through Meta's Cloud API carries no separate licence charge. You pay the per message rates, plus whatever a provider charges for its platform if you use one. Any page that presents a provider as a legal requirement for reaching the API is selling, not informing.
What is free, and what stopped being free on 1 October 2026
The free service tier. Each business phone number gets 1,000 free service messages per month. Service messages are your free form replies inside the 24 hour window after a customer messages you. Beyond 1,000 in a month, each service message costs Rs 0.1150. The allowance resets monthly and does not roll over.
What changed on 1 October 2026. Service messages were free from November 2024 to 30 September 2026. That ended. From 1 October 2026, service messages above the free tier are billed at the utility rate. Utility templates sent inside the 24 hour window, which used to escape charging, are also charged now. If your cost model was built before October 2026, rebuild it: a support heavy business that paid nothing for replies now pays for most of them.
The free entry point window. When a customer starts the conversation by clicking a Click to WhatsApp ad or a similar entry point and messaging you first, the messages in the window that follows are free for up to 7 days across categories, on the terms Meta publishes for entry point conversations. This is why ad led support and sales chats can cost less than their message count suggests, and why the source of a conversation belongs in your cost sheet.
The free Business App vs the API: which one do you need
The WhatsApp Business App is free, and for many small businesses it is enough. The API is a different product, bought for capabilities, not for status.
| Question | Business App | Business API |
|---|---|---|
| Cost | Free | Per delivered message, plus provider platform cost, plus GST |
| Phones and users | One phone, with linked devices for a small team | Multi user shared inbox, roles and assignment |
| Broadcasts | Limited lists, manual work | Template broadcasts at scale, with category pricing |
| Messages outside the 24 hour window | Not available as templates | Available, using approved templates |
| Automation and chatbots | Basic greetings and away messages | Full automation, flows and campaign tools |
| Connection to other software | Very limited | CRM, billing and support software connections |
| Best fit | Solo owner, low daily volume, replies by hand | A team sharing one number, order updates at volume, campaigns |
If one person answers every message on one phone, stay on the App and spend nothing. If two or more staff share a number, if order updates go out daily, or if you want your customer records and your chats in one system, you are in API territory. The software choice that usually follows is covered in CRM for a WhatsApp first business.
The provider layer, honestly labelled
Most small teams do not build on the raw API. They buy a provider: a shared inbox, template tools, automation and support, from companies such as AiSensy, Interakt and Wati. What you must separate is the Meta layer from the provider layer. Some providers pass Meta rates through and charge a plan fee. Others mark up every message. A single blended per message price tells you nothing until you split it.
The table below is drawn from a published India comparison checked on 29 October 2026. Provider prices move often, so treat this as the shape of the market, date stamped, and recheck the provider's own pricing page on the day you buy.
| Provider | Plan fee in the comparison | All in per message price in the comparison | Notes |
|---|---|---|---|
| AiSensy | Basic at Rs 1,500 per month | Marketing Rs 1.09. Utility, authentication and service Rs 0.145 | All in credits sit above Meta rates: compare with the card above to see the margin |
| Interakt | Growth at Rs 2,799 per month | Marketing Rs 0.949 to Rs 0.970 | Plan led pricing, per message cost varies by plan |
| Wati | Growth at Rs 2,699 per month for 3 users, billed quarterly | Template charges on top of the plan | User count drives the plan, so a growing team pays more before sending a single extra message |
Read any provider quote with three questions. Is the per message price Meta pass through or marked up, and by how much against Rs 0.8631 and Rs 0.1150? Is the plan fee monthly, quarterly or annual in the small print? Does the plan charge per user, and what happens when your team grows from three people to eight? The answers decide whether a cheap looking plan stays cheap. Providers sit inside a wider tools stack, which five digital tools for a small team puts in context.
How to get the API
Whether you go direct or through a provider, the setup has the same core steps.
- Create a Meta Business account for your business, if you do not have one.
- Create a WhatsApp Business Account inside it, with your business details.
- Add a phone number for the API. A number already locked into a conflicting setup can block activation, so decide early whether you will use your existing business number or a fresh one.
- Add a payment method to the account. Meta bills delivered messages against it, unless your provider bills you for messages instead.
- Create your first templates and get them approved in the right category. Write the template for the job it actually does, marketing or utility, because the category sets the price.
- Connect your inbox or software: your own build on the Cloud API, or a provider account linked to the same WhatsApp Business Account.
One deadline belongs in every India setup plan. Businesses Meta lists as eligible for billing localisation must move all their WhatsApp Business Accounts to INR billing by 31 December 2026. From 1 January 2027, Meta will stop delivering messages from their non INR accounts. If your account still bills in another currency, treat the migration as part of this project, not as a January problem.
A worked example: one retailer's month, all three layers
Take an Indore home furnishings retailer, turnover Rs 2.4 crore, with one WhatsApp number. In one month it sends 5,000 marketing templates that are delivered, 4,000 utility templates that are delivered (order and dispatch updates), and 3,500 service replies inside the 24 hour window. Assume a provider that passes Meta rates through and charges a plan fee of Rs 1,500 per month, at the AiSensy Basic level shown in the comparison above.
Step 1: Marketing. 5,000 multiplied by Rs 0.8631 equals Rs 4,315.50.
Step 2: Utility. 4,000 multiplied by Rs 0.1150 equals Rs 460.00.
Step 3: Service. 3,500 minus 1,000 free equals 2,500 billable messages. 2,500 multiplied by Rs 0.1150 equals Rs 287.50.
Step 4: Meta subtotal. Rs 4,315.50 plus Rs 460.00 plus Rs 287.50 equals Rs 5,063.00.
Step 5: Add the provider plan. Rs 5,063.00 plus Rs 1,500 equals Rs 6,563.00.
Step 6: Add GST at 18%. Rs 6,563.00 multiplied by 18% equals Rs 1,181.34. Total bill for the month: Rs 6,563.00 plus Rs 1,181.34 equals Rs 7,744.34.
Now the sensitivity that decides your provider negotiation. If the same retailer used a markup provider at Rs 1.09 per marketing message, Step 1 alone becomes 5,000 multiplied by Rs 1.09 equals Rs 5,450, which is Rs 1,134.50 more in a single month, before GST. Volume makes small per message gaps large.
Common mistakes
1. Budgeting on the old per conversation model. That model ended on 1 July 2025. Any quote or blog built on conversations, or on free service messages without the 1,000 limit, will understate your bill.
2. Assuming replies are still free. Since 1 October 2026, service replies cost Rs 0.1150 each after the first 1,000 per number per month. A busy support number feels this first.
3. Comparing a markup price with a pass through price. Rs 1.09 all in and Rs 0.8631 plus a plan fee are different structures. Split every quote into Meta layer, provider layer and GST before you compare.
4. Forgetting GST. Meta and provider charges carry 18% GST on top. A pre GST total is not your bill, as Step 6 of the example shows.
5. Using a marketing template for a utility job. An order update sent as marketing costs Rs 0.8631 instead of Rs 0.1150. At 4,000 messages a month, that single habit costs about Rs 2,992 extra. Classify templates by the job they do, and use AI tools for drafting and support workflows where they genuinely help, as set out in the best AI tools for a small business in India.
Frequently asked questions
Start on the free Business App if one person handles chats on one phone. Move to the API when you need several staff on one number, automation, template broadcasts, or a connection to your customer records. The App is a starting point, not a failure to upgrade.
