WhatsApp chatbot for business: what it costs in India in 2026, and when it is worth setting up
Meta now bills WhatsApp per message, and service replies past 1,000 a month are no longer free. Current India rates, Wati and AiSensy prices, and real monthly budgets.
One r/StartUpIndia user built a WhatsApp bot for a wooden furniture manufacturer that gets 50 to 60 IndiaMART leads a day. It replied to every lead in under 30 seconds. Then, in their words, "Meta silently dropped 50% of my messages in week one." Customers were also typing things like "price kya hai bhai", which a plain AI prompt kept missing.
That is a WhatsApp chatbot for business in practice: useful, cheaper than a staff member, and full of rules nobody mentions up front.
The short answer on cost: in India, a small business on a platform such as Interakt, Wati or AiSensy pays about ₹2,800 to ₹4,000 a month in subscription, plus Meta's per-message charges and 18% GST. Most land between ₹3,000 and ₹8,000 a month ($35 to $90). Here is where that money goes, and what changed on 1 October 2026.
WhatsApp Business app or the API: which one you need#
There are two products, and people mix them up.
The WhatsApp Business app is free. It has a business profile, catalogue, quick replies and greeting messages. Since July 2026 it also includes Meta Business Agent in India, an AI that learns from your past chats, website and catalogue and replies for you. Meta says it is free each month up to an included allowance, with more replies through its paid Meta One plans.
Solo owners should try it first. Early reviews are mixed: one r/WhatsappBusinessAPI user found it did well from chat history alone, then "fed it a word doc with instructions + an excel and its got worse." Another pointed out that once you have a team or a CRM, "the native tool just isn't there."
The WhatsApp Business Platform (the Cloud API) is what proper chatbots run on. You need it for bots that use your own booking or order systems, several staff on one number, automatic order or appointment messages, and broadcasts to opted-in customers. You can use it directly or through a Business Solution Provider (BSP) such as Interakt, AiSensy, Wati or Gupshup, which adds a dashboard, bot builder and shared inbox.
How Meta charges for WhatsApp in 2026#
Since 1 July 2025 Meta charges per delivered message, by category and the customer's country code.
On 1 October 2026, Meta started charging for service messages (your free-form replies inside the 24-hour window after a customer messages you). Each business phone number gets 1,000 free service messages a month, which do not roll over. From the 1,001st, every reply is billed.
Meta's own pages disagree, so here is the current truth#
Meta's developer pricing docs, updated 30 September 2026, describe the 1,000 free service messages and the charge after that. Meta's marketing pricing page, which we checked today, still says "we do not charge for service messages".
The developer docs and the official rate card are what you are billed on, and both AiSensy and Interakt now show service messages as charged after the first 1,000. Articles ranking for this topic that still call service replies free are out of date.
The same gap exists for Click-to-WhatsApp ads. If someone messages you from one of these ads on their phone and you reply within 24 hours, a free entry point window opens. The developer docs say it can stay open for up to seven days; the marketing page and AiSensy still say 72 hours. Plan on 72 hours, and if you run these ads, read our guide to Meta ads fake leads first.
Here are Meta's list rates for Indian (+91) numbers, from the INR and USD rate cards effective 1 October 2026:
| Message type | What it is for | Meta rate per message |
|---|---|---|
| Marketing | Offers, broadcasts, abandoned cart nudges | ₹0.8631 ($0.0118) |
| Utility | Order updates, appointment reminders, invoices | ₹0.115 ($0.0014) |
| Authentication | One-time passwords | ₹0.115 ($0.0014) |
| Service | Replies inside the 24-hour window | First 1,000 a month free, then ₹0.115 ($0.0014) |
What the platforms charge on top#
Indian prices from each vendor's pricing page today, monthly billing, before GST. BSPs also add a margin to Meta's per-message rates.
| Platform | Entry plan with a bot | Per-message (marketing / utility / service after 1,000) |
|---|---|---|
| Interakt | Growth ₹2,799 (linear bots and FAQ automations). Branching bots with API calls need Advanced at ₹3,799. AI agent add-on ₹3,000 | ₹0.958 / ₹0.150 / ₹0.128 on Growth |
| Wati | Growth ₹2,999 (₹2,699 if billed quarterly). 3 users, 1 AI agent, 2,000 AI credits, 1,000 automation triggers | Listed on a separate rate card |
| AiSensy | Basic ₹1,500, plus Chatbot Flows add-on ₹2,500. AI Chat Agent add-on ₹1,350 for 1,000 AI messages | ₹1.09 / ₹0.145 / ₹0.145 |
Watch the limits too. Wati's Growth plan includes 1,000 automation triggers a month, and AiSensy's chatbot is not in the base plan, so its real starting price for a bot is ₹4,000. In one r/whatsapp thread comparing these providers, a reply listed "pricing transparency (hidden markups)" as what actually matters. Compare the per-message column, not just the subscription.
Realistic monthly budgets for a WhatsApp chatbot for business#
These are worked examples using the rates above, not client figures.
A Jaipur boutique selling on Instagram and WhatsApp#
Interakt Growth at ₹2,799. About 2,000 marketing broadcasts a month for new arrivals (₹1,916) and 1,500 order and shipping updates (₹225). Customer replies stay under the free 1,000. Total: roughly ₹4,940 plus GST, about $56.
A Nagpur skin clinic#
AiSensy Basic plus Chatbot Flows at ₹4,000 for a booking bot. Around 600 appointment reminders (₹87) and 1,500 service replies, of which 500 are billed (₹73). Total: about ₹4,160 plus GST, roughly $47. The subscription is most of the bill.
A Kochi coaching centre building its own bot on the Cloud API#
No platform fee. 5,000 class reminders (₹575) and 2,000 billed replies (₹230) at Meta's rates, plus hosting and AI usage of ₹1,000 to ₹3,000. Total: roughly ₹2,000 to ₹4,000 ($23 to $45), plus a one-off build and upkeep.
Our view: start on a BSP, and build your own once the margins hurt or you need deep links into your software. Our launch checklist for app builds covers the security basics for a bot backend.
What a good WhatsApp bot does (and what annoys people)#
The bots customers like are short: they answer timings, fees and delivery questions in one message, book and remind, share order status, qualify leads with two or three questions, and hand off to a human the moment someone asks or gets stuck. What annoys people: ten-option menus, bots that ignore typed questions and daily promotional blasts.
Meta's business messaging policy says automated replies must come with "prompt, clear, and direct escalation paths", such as a transfer to a person, a phone number or an email. A bot with no way out is a policy problem as well as a bad experience.
AI chatbots on WhatsApp: useful, with limits#
An AI bot handles free-text questions in Hinglish, Tamil or English far better than a menu bot. The risk is confident wrong answers. In 2024 a Canadian tribunal made Air Canada pay a customer after its website chatbot gave wrong refund advice, and rejected the airline's argument that the bot was responsible for its own actions. If your bot quotes a discount you do not offer, that is your problem.
Keep it answering only from your own price list, policies and FAQs, and hand off when it is unsure. We go deeper in our guide to the cost of an AI chatbot for your website.
Two Meta rules matter. Section 4.7 of the WhatsApp Business Platform terms bars AI providers whose AI is the primary product; a bot for your own shop is a different case. And Meta's Business Agent on the API costs $2 per million tokens, which Meta puts at 4 to 5 US cents a message, roughly 30 times an Indian service reply.
Opt-in and template rules in plain English#
- Opt-in first. Only message people who gave you their number and agreed to hear from you. A bought list does not count.
- Templates need approval. Messages you start outside the 24-hour window must use an approved template, and Meta can recategorise a "utility" template as marketing if it reads like a promotion.
- Make opting out easy, including requests made by phone or in person.
Common questions#
Is a WhatsApp chatbot free?#
Partly. The Business app's quick replies and its built-in Meta Business Agent cost nothing up to Meta's included allowance. Bots on the API always carry Meta's message charges, and most BSPs charge a subscription.
What is the WhatsApp chatbot price per month in India?#
For a small business on a BSP, budget ₹3,000 to ₹8,000 a month including messages, before GST. The subscription is usually the biggest part until you broadcast in large volumes.
Are WhatsApp service replies still free?#
Only the first 1,000 per number each month, since 1 October 2026. After that Meta charges ₹0.115 per reply at list price, and BSPs charge ₹0.128 to ₹0.145.
Can I use a free WhatsApp bot from GitHub instead?#
Most free projects automate WhatsApp Web, not Meta's official API. WhatsApp's terms forbid unauthorised automated use, so you risk losing the number your customers know.
The short version#
If you get more WhatsApp chats than one person can answer, a WhatsApp chatbot for business is worth it. Try Meta's free Business Agent if you work alone. Otherwise budget ₹3,000 to ₹8,000 a month on a BSP, compare per-message margins, and remember that service replies past 1,000 a month now cost money, whatever older pages say. Keep the bot narrow, offer a quick route to a human, and make sure your landing page gives people a clear reason to message.
