Sonic Infosystem is a whatsapp chatbot development company in Navi Mumbai that builds WhatsApp Business API bots and AI website assistants for growing businesses. Our chatbots answer customers instantly, collect the details your sales team needs and pass serious buyers to a person.
In India, WhatsApp is where customers ask for prices, send requirements and chase orders. Enquiries arrive at all hours, and a slow reply often means a lost sale. A well-designed chatbot closes that gap without adding staff.
What we build
WhatsApp Business API chatbots
Official, verified business accounts with automated replies, quick-reply menus, product catalogues, broadcast campaigns and a shared inbox for your team. We handle the API application through an official provider.
AI website assistants
A chat assistant trained on your products, services and FAQs that answers in natural language, stays on-topic and hands over to a person whenever it is unsure.
Lead qualification and bookings
The bot asks the right questions (product, quantity, location, timeline), books appointments or site visits, shares brochures and price lists, and gives order status updates.
Integrations
Leads flow automatically to your CRM, Google Sheets, email or website admin panel. Combined with our business automation work, follow-ups and reminders run on their own.
Why work with a WhatsApp chatbot development company
Basic auto-reply tools are fine for a greeting, but they cannot qualify a lead, check an order or answer a technical product question. As a whatsapp chatbot development company with in-house developers, we design the conversation, connect it to your data and keep a clear path to a human. That means:
- Every enquiry is acknowledged in seconds, even at night or on holidays.
- Your sales team receives a tidy summary instead of a long chat thread.
- Repeat questions about timings, prices or documents are answered without staff time.
- Broadcasts reach customers who have opted in, within WhatsApp policy.
Who chatbots work best for
- Clinics and healthcare: appointment booking, timings and pre-visit information.
- Manufacturers and exporters: product enquiries, specifications and documentation requests, in more than one language.
- Travel companies: package enquiries and booking follow-ups.
- Online stores: order tracking, return requests and catalogue browsing (see e-commerce development).
- Service businesses: quotes, service requests and reminders.
Our chatbot development process
- Discovery: we study your common enquiries and how customers buy from you.
- Conversation design: menus, questions and handover points agreed with your team.
- Setup: WhatsApp Business API approval, AI training and integrations.
- Testing: real scenarios, wrong inputs and edge cases checked before launch.
- Launch and review: we read conversations after launch and improve answers.
AI chatbot development in Mumbai and Navi Mumbai
We work with clinics in Kharghar and Nerul, traders and manufacturers in Vashi, Turbhe and Airoli, and offices across Mumbai from Andheri and Goregaon to Powai. Discovery sessions can be held at your office or online, and for businesses outside Mumbai we run the whole project remotely. Local teams often want Hindi or Marathi replies alongside English, and we plan the conversation flows for that from the start.
Why choose Sonic Infosystem for your chatbot
- 20+ years of web & SEO experience, so the chatbot fits your website and marketing rather than sitting apart from it.
- Developers in-house for custom integrations in PHP and Laravel.
- AI restricted to your approved information, with clear rules on what it should not answer.
- Ongoing support as products, prices and policies change.
What affects chatbot pricing
Cost depends on the number of conversation flows, whether you need AI answers or menu-based replies, the systems it connects to and your WhatsApp message volume, which is billed separately by Meta through the API provider. We share a clear scope before work begins.
WhatsApp & AI Chatbots: common questions
How much does WhatsApp chatbot development cost?
It depends on the number of flows, whether you need AI answers, the integrations required and your message volume. WhatsApp conversation charges from Meta are separate. We share a fixed scope after discovery.
Do I need the WhatsApp Business API?
For automation, broadcasts and multiple team members on one number, yes. We handle the application and verification for you through an official WhatsApp Business API provider.
Can the chatbot reply in Hindi or other languages?
Yes. AI assistants can answer in English, Hindi, Marathi and many other languages, which helps both local customers and overseas buyers who prefer their own language.
Will the AI chatbot give wrong answers?
We restrict the AI to your approved information and set rules for topics it must not answer. Anything uncertain is handed to your team, and we review conversations regularly after launch.
How long does it take to set up a chatbot?
A standard WhatsApp or website chatbot is usually live in two to four weeks, including API approval, conversation design, training and testing. Larger integrations can take longer.
