WhatsApp bot development at Nexta, in short

WhatsApp chatbot development means building an automated assistant on Meta's official WhatsApp Business Platform that answers customers, takes bookings or orders, shares payment links and passes difficult chats to your staff. Nexta Web Solution builds bots connected to your own systems, in English, Bengali or Hindi. Builds start at ₹24,999 plus Meta's message charges, and a typical bot goes live in two to four weeks.

What WhatsApp feels like without a proper bot

“Customers message at 11 pm and we reply next morning”

By then they have asked two other shops and bought from whoever answered first. Your staff are not to blame; they go home.

“The same five questions, all day”

Price, timing, location, "where is my order", "is my fee due". Your best people spend the day typing answers that never change.

“Our number got banned”

A cheap bulk tool or a WhatsApp Web automation app worked for a few weeks. Then the number was blocked, and with it the chat history and every customer who saved it.

“The bot we bought cannot see our orders”

It shows a nice menu, then says "please call us" for anything that needs real data. Customers stop using it after the first try.

“People feel trapped in menus”

Press 1, press 3, back to the start. There is no way to reach a human, so they give up or leave an angry review.

What our WhatsApp chatbot development includes

Official API setup in your name

Meta Business verification, WhatsApp Business Account, display name approval and phone number setup, through Meta's Cloud API directly or a Business Solution Provider you choose. We explain what happens to the number when it moves from the WhatsApp Business app.

Buttons, lists and WhatsApp Flows

Customers tap instead of typing. For structured requests such as a table booking, an admission enquiry or a service complaint, we use WhatsApp Flows forms so the details arrive clean and complete.

Live answers from your own systems

Order status from Shopify, WooCommerce or your ERP, open appointment slots, fee dues, courier tracking. The bot reads your data through APIs or a small connector we build, so answers are current.

Payments inside the chat

Razorpay or Cashfree payment links and UPI intent, confirmed by webhook, with a receipt sent back in the same chat. Your accounts team sees the payment against the right order.

AI replies with limits

Optionally, an AI layer answers free-text questions from your approved FAQ and price list. It does not invent prices or promise refunds, stays on your business, and hands over when unsure.

Hand-off to a person

A "talk to someone" button and keyword triggers route the chat to the right department, aware of office hours, with the full history visible. Your team replies from a shared inbox, not a single phone.

Updates and CRM entries

Order confirmations, dispatch notices and appointment reminders go out as approved utility templates. New leads land in your CRM or a Google Sheet with the chat attached.

From chat export to live bot

  1. 1Week 1

    Conversation design

    We read an export of your real chats, pick the questions that come up most, and draw the flows and hand-off rules on paper with you.

  2. 2Week 1-2

    Meta setup and templates

    Business verification, number connection, and template submissions in the right category, so approvals do not hold up launch.

  3. 3Week 2-3

    Build and connect

    Flows, integrations with your store or software, payment webhooks and the shared inbox.

  4. 4Week 3

    Staff test

    Your team tries to break it, and native speakers check the Bengali and Hindi wording.

  5. 5Week 4

    Launch and watch

    For the first fortnight we read transcripts, find where people drop off, and fix the flows.

Why our bots stay on the right side of Meta

Official API only

We do not use WhatsApp Web scrapers or bulk-sender apps. Those break WhatsApp's terms, and when the number is banned you lose it along with your history. Meta's policy also expects opt-in before you message someone and a clear path to a human, and we build both in.

Your number, your account

The WhatsApp Business Account, Meta Business portfolio and any provider account sit in your name. We are added as a partner or admin, and you can remove us at any time.

A bot is not a campaign tool

This page is about conversations customers start. Promotional broadcasts to opted-in contacts are a separate job, covered on our WhatsApp marketing page. Keeping them apart stops your helpful bot from turning into spam.

Straight talk on Meta charges

Since July 2025 Meta bills per template message. Free-form replies inside the 24-hour window after a customer writes are not charged, and utility templates sent inside that window are free. We estimate your monthly bill before launch.

Is this right for you?

A good fit if

  • Shops and online stores answering order and delivery questions all day
  • Clinics, labs and salons that take bookings over WhatsApp
  • Schools and coaching centres fielding fee and admission questions
  • Service businesses that need complaints logged with photos and a ticket number

Probably not the right fit if

  • A few chats a day: the free WhatsApp Business app with quick replies and an away message is enough
  • Messaging bought or scraped number lists; that is against Meta's rules and we will not do it
  • Answers that change daily with no system or sheet for the bot to read from
  • Wanting a general-purpose AI chat service for the public rather than a bot for your business

WhatsApp bot development: frequently asked questions

Our WhatsApp bots start at ₹24,999 plus GST for the build. The final quote depends on how many flows you need and which systems the bot must read from, such as your store or billing software. Meta charges per template message on top, and those charges go to Meta or your provider at cost. You get a written quote within 24 hours of a free call.

Usually yes. A number running on the WhatsApp Business app can be connected to the Business Platform. Depending on your setup, it either moves fully to the API or runs in Meta's coexistence mode, where available, alongside the app. We check what your number supports before starting and tell you exactly what happens to existing chats.

A bot handles conversations your customers start: questions, orders, bookings, complaints. WhatsApp marketing is about messages you start, such as offers and reminders sent to people who opted in, using approved templates. Many businesses need both, but they are planned and measured differently, so we keep them as separate pieces of work.

If the customer writes first, the bot can reply freely inside the 24-hour window. For any message you start, Meta's policy requires that the person gave you their number and agreed to hear from you. We add opt-in steps to your website forms, checkout and the bot itself, and keep a record of each consent.

Yes. Menus, buttons and replies can be in Bengali, Hindi, English or a mix, and the bot can switch based on the customer's choice. Our team in Hooghly writes and checks the Bengali and Hindi wording, so it reads like a local shop talking, not a machine translation.

Meta charges per delivered template message, with rates that vary by category, such as marketing, utility or authentication, and by the recipient's country. Replies inside the 24-hour window after a customer writes are free, and so are utility templates sent inside that window. We share the current rate card and an estimate for your volumes.

It can if it is left to guess, which is why we do not let it. Answers come from your approved content and live data, prices come only from your price list, and anything outside scope goes to a person. In the first weeks we read transcripts and tighten the rules wherever an answer was weak.

Yes. The Business Platform works across countries, though Meta's rates differ by the recipient's country, which we include in the estimate. We work with clients in the UK, the Gulf, Australia and North America, sign an NDA on request and quote in USD, GBP or AED.
