Chatbot Development
Chatbot Development
BitGoLabs is a chatbot development company building custom bots that automate customer support, sales, order updates, appointment booking, notifications and internal workflows for companies and organisations. We build two types of chatbot: WhatsApp chatbots on the official WhatsApp Business Platform (Cloud API) and Telegram bots on the Telegram Bot API. Both connect to your CRM, ERP, payment and database systems and add AI-powered conversations with human-agent handover when a customer needs a person.

What our chatbot development includes
Official WhatsApp Business Platform & Telegram Bot API
Bots are built on Meta's WhatsApp Business Platform (Cloud API) and the Telegram Bot API, not unofficial workarounds that risk number bans. We support business verification, number registration and message-template approval so you launch on a stable, policy-compliant footing.
AI Conversations Trained on Your Content
Retrieval-augmented AI answers questions in natural language from your own documents, FAQs, catalogues and policies. Confidence thresholds, guardrails and a clear 'I don't know' fallback keep answers accurate, and every response is logged for review.
Human Handover & Shared Agent Inbox
When a customer asks for a person, or the bot is unsure, the chat moves to a live agent with the full history, customer details and context. Agents reply from a shared inbox, and the bot can resume once the issue is resolved.
CRM, ERP, Helpdesk & Payment Integrations
Connect the bot to HubSpot, Zoho, Salesforce, Shopify, WooCommerce, Zendesk, Freshdesk, Google Sheets, your internal database or any REST API. Leads, orders, tickets and payments sync both ways, so the chat is part of your workflow, not a silo.
Broadcasts, Templates & Opt-In Management
Send segmented, template-based notifications and campaigns to contacts who have opted in, with delivery, read and reply reporting. Opt-in and opt-out are captured and stored so your messaging stays within platform policy and local regulation.
Multilingual & Rich Message Flows
Serve customers in their own language with automatic language detection, and use buttons, lists, carousels, images, documents, location and voice notes on WhatsApp, plus inline keyboards, commands and mini-apps on Telegram.
Show 2 more capabilities
In-Chat Payments, Bookings & Forms
Collect payments, confirm bookings, capture documents and run multi-step forms inside the conversation, so customers complete a task in one place and you reduce drop-off from redirects and long web forms.
Analytics Dashboard & No-Code Content Control
Track conversations, resolution rate, handover rate, popular questions, lead conversion and response times. Your team edits replies, menus, templates and knowledge-base content from an admin panel without a developer.
Use cases
Who uses chatbot development
Where teams put this to work.
E-commerce, Retail & D2C Brands
Share product catalogues in chat, answer stock and delivery questions, send order confirmations and shipment tracking, recover abandoned carts with approved reminder templates, and take payments inside the conversation. Orders sync with Shopify, WooCommerce, Magento or a custom backend.
Banking, Fintech & Insurance
Handle balance and policy enquiries, payment reminders, KYC document collection, claim status updates and OTP-style alerts through authenticated flows. Sensitive journeys use identity checks, encrypted storage and full audit logs so compliance teams can review every interaction.
Healthcare, Clinics & Wellness
Book, reschedule and cancel appointments, send reminders to reduce no-shows, share prescriptions and lab-report notifications, and answer common pre-visit questions. Patient data handling follows your privacy obligations, and urgent or clinical questions are routed to staff.
Education, Training & EdTech
Answer admission queries, deliver class schedules and assignment reminders, collect fee payments, run quizzes and send results. Telegram channels and groups also work well for cohort communities and course announcements.
Travel, Hospitality & Real Estate
Qualify enquiries, share listings or itineraries, confirm bookings, send check-in details and collect feedback. Lead details flow straight into your CRM and the right salesperson is notified instantly.
Crypto, Web3 & Online Communities
Telegram is where many crypto and community projects live. We build community moderation bots, price and portfolio alert bots, airdrop and referral bots, token-gated access, and support assistants for large groups and channels.

Types of Chatbots We Build: WhatsApp and Telegram
BitGoLabs builds two types of chatbot. WhatsApp chatbots run on the WhatsApp Business Platform (Cloud API) and suit customer-facing work: support, orders, payments, bookings, template-based notifications and campaigns to customers who have opted in. Telegram bots run on the Telegram Bot API and suit communities, channels and groups, fast self-serve support, alerts, in-chat payments and mini-apps, and internal team tools. Many clients run both on one shared backend and one dashboard. Whichever channel you choose, the chatbot can take on these roles, from simple menu flows to AI assistants wired into your core systems. Customer support bots answer FAQs, check order or ticket status and escalate to a live agent with the whole chat history attached. Sales and lead-generation bots qualify prospects with a short question flow, score the lead and push it into your CRM (HubSpot, Zoho, Salesforce or a custom system). Order and payment bots let customers browse a catalogue, place an order and pay inside the chat. Appointment and booking bots sync with Google Calendar, Calendly or your own scheduling database. Notification and alert bots send transactional messages such as order updates, invoices, payment reminders and OTPs through approved WhatsApp templates and Telegram messages. Broadcast and campaign tools send segmented messages to opted-in contacts and report on delivery and replies. AI knowledge-base bots use retrieval over your own documents, product manuals and policies to answer in natural language, and say so when they do not know. Community bots for Telegram handle moderation, welcome flows, polls, giveaways, gated access and group analytics. Internal workflow bots let employees request leave, raise IT tickets, pull reports and approve requests from the chat apps they already use.

Our Chatbot Development Process & Technology
We start with a conversation audit: which questions and tasks make up most of your chat volume, which systems hold the answers, and which journeys must always reach a human. From that we design the conversation flows, tone of voice and escalation rules before writing code. On WhatsApp we set up the WhatsApp Business Platform (Cloud API) through Meta, help with business verification, phone-number registration and message-template approval, and implement opt-in capture so your messaging stays inside Meta's policies. On Telegram we build on the Bot API with inline keyboards, commands, mini-apps, payments and webhooks. The backend is written in Node.js (TypeScript) or Python with queue-based message handling, so a spike in traffic does not drop messages, and PostgreSQL, MongoDB or Redis store sessions and conversation state. For AI bots we connect a large language model through a retrieval layer over your approved content, add guardrails, confidence thresholds and a fallback to a human, and log every answer for review. Integrations cover CRMs, helpdesks, payment gateways (Stripe, Razorpay, PayPal), e-commerce platforms, Google Sheets and any REST API you already run. We test with real conversation scripts, deploy on your cloud or ours, set up monitoring and alerting, and train your team on the admin dashboard.

FAQ
Frequently asked questions
Answers about chatbot development: cost, timeline, security and deployment.
What types of chatbots does BitGoLabs develop?
We develop two types of chatbot. WhatsApp chatbots are built on the WhatsApp Business Platform for customer-facing support, sales, orders, bookings and notifications. Telegram bots are built on the Telegram Bot API for communities, channels, alerts, payments, mini-apps and internal tools. Both can use AI, connect to your CRM and systems, and hand over to a human agent, and you can run both from one backend and dashboard.
What is a WhatsApp chatbot and how can it help my business?
A WhatsApp chatbot is software that talks to your customers on WhatsApp through the official WhatsApp Business Platform. It can answer common questions instantly, share catalogues, take orders and payments, book appointments, send order and payment notifications, and pass the chat to a human agent when needed. It lets a small team handle far more conversations without longer waits.
Do you use the official WhatsApp Business API?
Yes. We build on Meta's WhatsApp Business Platform (Cloud API), including business verification, phone-number registration and message-template approval. We do not use unofficial or scraped-session methods, because they violate WhatsApp's terms and can get your number banned.
Can you build a Telegram bot as well as a WhatsApp bot?
Yes. We build Telegram bots for customer support, sales, community moderation, notifications, payments and mini-apps using the Telegram Bot API. Many clients run both: WhatsApp for customer-facing conversations and Telegram for communities, internal teams or alerts, with one shared backend and one dashboard.
Can the chatbot use AI and answer questions from our own documents?
Yes. We connect a large language model to a retrieval layer over your approved documents, FAQs, product data and policies, so answers come from your content. We add guardrails and confidence thresholds, and the bot hands over to a human or says it does not know instead of guessing. All answers are logged so you can review and improve them.
Will the bot integrate with our CRM, website and payment systems?
Yes. We integrate with CRMs such as HubSpot, Zoho and Salesforce, helpdesks such as Zendesk and Freshdesk, e-commerce platforms such as Shopify and WooCommerce, payment gateways such as Stripe, Razorpay and PayPal, Google Sheets, and any system with a REST API. Custom or legacy databases can be connected through a secure API layer.
Can customers talk to a real person?
Yes. The bot can hand over to a live agent when the customer asks, when the bot is unsure, or when a topic is on your always-escalate list. The agent sees the full conversation and customer details in a shared inbox, and can return the chat to the bot afterwards.
How do you handle data privacy and security?
We use encrypted transport and storage, role-based access to the admin panel, secure handling of API tokens, and audit logs. We capture and store opt-in consent, support deletion requests, and can deploy on your own cloud or region to meet data-residency needs. Sensitive flows can add identity verification steps. Compliance with GDPR and local rules is built into the design, and you remain the data controller.
How long does it take to build a WhatsApp or Telegram bot?
A focused FAQ or notification bot can usually launch in 2–4 weeks. A bot with CRM and payment integrations typically takes 4–8 weeks, and an AI assistant with multiple integrations and a custom dashboard 8–12 weeks. WhatsApp business verification and template approval are handled in parallel, but Meta's review time is outside our control.
How much does WhatsApp chatbot development cost?
Cost depends on the number of flows, integrations, whether AI is included, languages, and channels. As a startup-friendly team, a basic single-channel bot typically starts around $1,500–$4,000, a bot with integrations and a dashboard around $4,000–$12,000, and enterprise multi-channel AI assistants from $12,000 upward. WhatsApp message fees charged by Meta and any AI model usage are separate running costs, and we give you an estimate of those during scoping.
Do you provide support after launch?
Yes. We offer monthly maintenance plans covering monitoring, updates for WhatsApp and Telegram API changes, new template submissions, knowledge-base updates, flow improvements and performance reports, so the bot keeps improving after go-live.
