AI chatbot cost in India (2026): from ₹30,000 FAQ bots to ₹15 lakh RAG systems
By Samuel Marndi · Updated
The short answer
AI chatbot development in India costs ₹30,000–₹75,000 for a basic FAQ bot, ₹1,00,000–₹4,00,000 for a business chatbot with CRM integration, WhatsApp and website deployment, lead routing and analytics, and ₹6,00,000–₹15,00,000 for a full RAG system trained on private documents with permissions and citations.
Model usage is billed separately and is usage-based. Any competent build forecasts it from your real conversation volume and configures a hard cap before launch, so a traffic spike cannot become an unexpected invoice.
What you get at each price
| Tier | Cost | What it does |
|---|---|---|
| FAQ / scripted bot | ₹30,000 – ₹75,000 | Answers a fixed set of questions, hands off to a human |
| Business bot with integrations | ₹1,00,000 – ₹4,00,000 | CRM, WhatsApp and website, lead qualification, routing, analytics |
| RAG on private documents | ₹6,00,000 – ₹15,00,000 | Answers grounded in your documents, with citations and permissions |
| Document / invoice extraction | ₹75,000 – ₹3,00,000 | Pulls structured data from PDFs into your system with a review queue |
| AI use-case audit | ₹25,000 – ₹60,000 | A written verdict on what is worth automating first |
Why RAG costs ten times more than an FAQ bot
An FAQ bot matches a question to an answer you wrote. A RAG system indexes your entire document estate, retrieves the right passages at question time, respects who is allowed to see what, cites its sources, and refuses when it has none.
Most of that cost is not the model. It is data preparation, chunking strategy, permission modelling, and building an evaluation set so accuracy is measured rather than assumed. Training a system on 10,000 pages of documentation and support history adds ₹50,000–₹3,00,000 to a project on its own.
Controlling the monthly bill
- Forecast from real volume: conversations per day × average tokens, not a guess
- Route routine questions to a cheaper model and hard ones to a stronger one
- Cache repeated content so the same context is not paid for twice
- Set a hard spending cap at the provider before launch, not after the first surprise
- Log and review monthly — usage patterns change as staff find new uses
FAQ
Related questions
Is a chatbot worth it for a small business?
If your team answers the same twenty questions daily, usually yes — and an FAQ bot at ₹30,000–₹75,000 pays back quickly. If enquiries are varied and consultative, a bot often frustrates customers, and document extraction or lead qualification is the better first AI project.
Will the chatbot invent answers?
A properly built one will not: answers are grounded in your documents, cite sources, and refuse plus escalate when no source exists. Ask any vendor to show you the accuracy numbers against a real question set before you buy.
Can it run on WhatsApp?
Yes, via the WhatsApp Business API — and in India that channel usually outperforms a website widget, because customers are already there.
