WhatsApp chatbot for business: menu bots vs AI assistants, costs and setup
A WhatsApp chatbot answers customers on your business number automatically. There are two kinds: menu bots, which reply with fixed buttons and options, and AI chatbots, which read the message and reply in normal language from facts you provide. Both need the official WhatsApp Business API. Menu bots suit fixed tasks like order status; AI chatbots suit sales enquiries, where every question is different. The best setups hand the chat to a person when the customer asks or the bot is unsure.
“We need a WhatsApp chatbot” usually means “we are missing leads because nobody replies fast enough”. A chatbot can fix that, or it can frustrate customers with endless menus. The difference is which kind you choose and how you set it up.
What a WhatsApp chatbot can do
- Reply instantly, at any hour, on your business number.
- Answer common questions: prices, timings, location, eligibility, documents.
- Qualify leads: budget, location, timeline, what exactly they need.
- Book visits, demos and appointments, or offer slots for a person to confirm.
- Send updates: confirmations, reminders, order status.
- Hand over to a person when the customer wants one.
Menu bots vs AI chatbots
| Menu (rule-based) bot | AI chatbot | |
|---|---|---|
| How it replies | Fixed buttons and flows you design | Reads the message, replies in normal language |
| Handles free text | Poorly (“Sorry, I didn’t understand”) | Yes, including Hinglish and typos |
| Setup | Build every flow by hand | Write your business facts once |
| Best for | Order status, invoices, simple FAQs | Sales enquiries, varied questions |
| Risk | Customers get stuck in menus | Wrong answers if not limited to your facts |
Many businesses end up with both: a few buttons for fixed tasks, AI for everything else. More on AI: what an AI sales assistant can and can’t do.
What you need to run one
- The WhatsApp Business API (WhatsApp Business Platform). The free app cannot run a chatbot; it only has greeting and away messages. See app vs API.
- A provider or CRM that connects your number and runs the bot.
- Your business facts: what you sell, prices, timings, policies, and what you never promise.
- A handover rule: when and to whom the chat goes.
What it costs in India
- Software: free to start on some tools, otherwise a monthly plan.
- Meta’s message charges: replies to customers inside the 24-hour window are service messages; templates you send to start conversations are charged per message. See WhatsApp API pricing in India.
- AI usage (AI chatbots): usually a fraction of a rupee per reply. Set a monthly cap.
For most small businesses the total is far less than one extra salary, and the bot works nights and Sundays.
Industry examples
- Real estate: answers project price questions, asks budget and location, offers site visit slots. See real estate.
- Clinics and hospitals: treatment questions, doctor timings, appointment requests, never medical advice. See clinics.
- Coaching and education: fees, batch timings, demo classes, admission documents. See coaching institutes.
- Travel: package prices, dates, inclusions, quote requests. See travel agencies.
- Home services: service charges, available slots, area coverage. See home services.
How to set it up without annoying customers
- Answer the question first. Don’t make people pick from a menu before you answer what they asked.
- Keep replies short, two to four lines, like a person would.
- Use the customer’s language. If they write in Hindi or Hinglish, reply that way.
- Limit the bot to your facts. List what it must never promise: discounts, guarantees, medical or legal advice.
- Hand over fast when the customer asks for a person, wants to book, is upset, or the bot is not sure.
- Let your team take over in one tap, and keep the bot quiet once they do.
- Review chats weekly and add missing facts.
Example: a good AI chatbot reply
Lead: hi fees kitni hai NEET ki weekend batch ki?
Assistant: Hi! NEET weekend batch fee is ₹48,000 for the full year, payable in 3 instalments. Classes are Sat–Sun, 9 am to 1 pm, starting 12 January. Would you like to attend a free demo class this Saturday?
It answered the question, in the lead’s style, from real facts, and moved to the next step.
OakDeal’s AI assistant on WhatsApp
OakDeal’s AI replies to every new WhatsApp lead in seconds, using only the business facts you write, in the languages you choose. It notes what it learns, marks the lead Hot, Warm or Cold with the reason, and hands the chat to a person when the lead asks for one, wants a demo or the AI is unsure. Your team can take over any chat in one tap, and you can pause the AI for one chat or a whole channel.
Frequently asked questions
Can I make a WhatsApp chatbot for free?
The free WhatsApp Business app only has a greeting message, an away message and quick replies, not a real chatbot. A chatbot needs the WhatsApp Business API; some tools, including OakDeal, are free to start, and Meta charges only for template messages.
How much does a WhatsApp chatbot cost in India?
It is three costs: the software (free to a few thousand rupees a month for small businesses), Meta’s per-message charges for template messages, and for AI chatbots the AI usage, usually a fraction of a rupee per reply. Replies within 24 hours of a customer’s message are far cheaper than templates.
Is an AI chatbot better than a menu bot?
For sales, usually yes, because leads ask questions in their own words, in English, Hindi or a mix. For fixed tasks such as checking an order or downloading an invoice, menu buttons are faster.
Will customers know they are talking to a bot?
Be open about it. A short line such as "I’m the assistant for Sunrise Dental, a person will join if needed" builds trust. Customers mind slow or wrong answers far more than they mind a bot.
