Almost every quote you receive for a WhatsApp chatbot covers the build and goes quiet on what it costs to run. That second number is the one that decides whether the project makes sense, and it is the number a supplier is least likely to volunteer.
This post is the version we give clients before they commit. Lacewing Technologies is an AI and software development company in Navi Mumbai, and WhatsApp bots are the single most requested thing we build, so these figures come from quotes we have actually issued rather than from a pricing page.
What are the three costs of a WhatsApp chatbot?#
There are three, and only the first is a one-off. Suppliers quote the first and stay silent on the other two.
| Cost | Type | Typical range (India, 2026) |
|---|---|---|
| Build and integration | One-off | ₹45,000 – ₹2,00,000 |
| Meta message fees | Per message | ₹0.1150 – ₹0.8631 before GST |
| Model usage | Monthly | ₹2,000 – ₹8,000 at SMB volume |
| Hosting and monitoring | Monthly | ₹1,500 – ₹5,000 |
| Business Solution Provider | Monthly | ₹0 – ₹5,000 depending on provider |
The build range is wide because it is driven almost entirely by integrations. A bot that answers questions from your own content sits at the bottom. A bot that checks live stock, takes a payment, writes to your CRM and does all of it in three languages sits at the top.
What changed when Meta moved to per-message pricing?#
This is the part that makes older advice wrong, including the earlier version of this post.
Until mid-2025, Meta billed per 24-hour conversation window. You paid once when a conversation opened, and everything inside that window was included. The design advice that followed from it was sensible: resolve the enquiry inside the window, and message count did not matter.
That model is gone. Meta moved the WhatsApp Business Platform to per-message pricing on 1 July 2025, and you are now charged when a template message is delivered rather than when a conversation opens.
The practical consequence is a reversal. Under conversation billing, a chatty bot cost the same as a terse one. Under per-message billing, every extra template message you push out has a price on it. Broadcast-heavy and reminder-heavy designs got more expensive; inbound bots that answer questions inside an open service window got cheaper.
If a supplier quotes you a "per conversation" cost in 2026, they are working from a rate card that expired more than a year ago. Ask them to requote.
What do Meta's India rates actually work out to?#
Meta prices by message category, and the gap between categories is large enough to shape how you should design the bot.
| Category | What it covers | India rate (before GST) |
|---|---|---|
| Marketing | Promotions, offers, re-engagement | ₹0.8631 |
| Utility | Order updates, reminders, confirmations | ₹0.1150 |
| Authentication | OTPs and login codes | ₹0.1150 |
| Service | Replies inside an open 24-hour window | Free today |
One caveat on those figures. Meta documents the pricing model publicly, but the per-country rupee amounts live in rate cards selected by market and currency rather than on the pricing page itself. The numbers above are the list rates being published for India at the time of writing; treat them as accurate to the rupee only as of this post's date, and pull the current card before you build a business case on them.
Even so, the ratio is the durable part. Marketing costs roughly seven and a half times what a utility message costs, and that ratio should drive your template design more than anything else. A delivery update written as a marketing template, because someone added a discount line to the bottom, costs you seven times more than the same message sent as a utility template.
Two dates matter for budgeting. India marketing rates rose about 10% on 1 January 2026, from ₹0.7846 to ₹0.8631. And the current concessions, free service messages and free utility messages inside an open service window, are scheduled to end on 1 October 2026. Messages inside the 72-hour free entry point window, conversations that begin from a click-to-WhatsApp ad, are expected to stay free. If your business case depends on free utility messages, model it again without them before you sign anything.
All published India rates exclude GST, and 18% is added on the invoice. A ₹0.8631 marketing message costs ₹1.0185 delivered. Volume discounts of up to about 30% exist on utility and authentication as monthly volume grows, which matters at scale and is irrelevant for most first deployments.
What does the build itself actually cost?#
Build cost tracks integration count, not conversation cleverness. In rough order of what adds money:
- Content and FAQ training only. Your pages, price list and policies. Bottom of the range.
- Lead capture into a sheet or CRM. One integration, well-understood, adds modestly.
- Appointment booking against live availability. Needs a calendar system that can actually be queried.
- Live catalogue or stock lookup. Depends entirely on whether your inventory has an API.
- Payments inside the conversation. Adds reconciliation work and testing.
- Additional languages. Each language is more testing than translation, especially for Hindi and Marathi mixed with English.
Most SMB deployments we quote land between ₹60,000 and ₹90,000 for the build. Below ₹45,000 you are usually buying a template on someone else's platform, which is a legitimate choice as long as you know that is what you are buying and that you cannot take it with you.
What is the Business Solution Provider actually charging you for?#
You cannot connect to the WhatsApp Business Platform directly as a small business. Access runs through a Business Solution Provider, and their commercial models differ enough to change your total materially at the same message volume.
Three models are common in India. Some providers charge a flat monthly platform fee and pass Meta's rates through at cost. Some add a per-message markup on top of Meta's published rate and advertise no monthly fee. Some bundle a fixed allowance of messages into a monthly plan, which looks simple and is usually the most expensive per message once you exceed the allowance.
The question worth asking is blunt: what is your markup on Meta's published rate, and what is the monthly platform fee? A provider who will not answer that directly is giving you your answer. At the volumes most first deployments run, a flat fee with pass-through pricing is usually cheapest, and the calculation flips only once you are sending tens of thousands of marketing templates a month.
Check also whether the provider will let you migrate the number away later. The WhatsApp Business Account should be yours, and number portability between providers should be a supported process rather than a negotiation.
What should you ask a supplier before signing?#
Four questions. The answers tell you more than the quote does.
- What is the modelled monthly cost at my expected volume? Give them your real numbers: enquiries per day, expected broadcasts per month, ratio of marketing to utility templates. If they cannot produce a monthly figure, they have not built enough of these to know.
- Which of my messages will be marketing and which will be utility? A supplier who has not thought about template categorisation will cost you seven times over on every reminder.
- Have you repriced for the October 2026 change? It tests whether they are current.
- Who owns the code and the WhatsApp Business Account? The account should be registered to your business, not to the agency. Everything Lacewing Technologies builds transfers to the client on final payment, and you should expect that as standard rather than as a concession.
The honest summary#
A WhatsApp chatbot is one of the few AI projects where the numbers usually work, because the before-state is a person retyping the same four answers all day. But the payback depends on the running cost, and the running cost depends on message mix, not on how good the bot is.
Get the monthly figure modelled before you commit. If it is not in the proposal, it is not in the plan.
