Chatbot Development for Business: Telegram, WhatsApp

Chatbot development for business covers bots in Telegram, WhatsApp, Viber, Instagram and on your website that take orders, answer questions, book appointments and pass leads to your CRM, with AI answers where scripts are too limited.

In short

Channels: Telegram Bot API, WhatsApp Business Platform, Viber, Instagram and Messenger, website chat.
Script-based bots for orders and bookings; AI assistants on the OpenAI, Claude or Gemini APIs for open questions.
Integrations with KeyCRM, HubSpot or Pipedrive, Google Sheets and payment providers, often through n8n or Make.
The timeline is set after the specification; a script-based bot for one channel is the fastest option.
Support after launch: answer updates, new scenarios, monitoring.

What is included in chatbot development

Scenario design. A flowchart of dialogues for your top tasks: orders, bookings, questions, feedback.
Bot types we have built. Logistics, product catalogue, referral, parser bots and voice assistants.
AI assistant. Answers from your knowledge base through the OpenAI, Claude or Gemini APIs, with handover to a person when unsure.
Integrations. CRM, Google Sheets, booking systems, delivery and payment services; n8n or Make automations.
Payments. Invoices through LiqPay, WayForPay, Monobank acquiring or Stripe, depending on the market.
Broadcasts. Mailings, promotions and reminders to users who opted in.
Admin panel. Edit answers, see dialogues, statistics and user segments.
Training. We set the bot up in your channels and show your team how to work with it.

Where chatbots bring the most value

Bots work best on repeated tasks: taking orders, booking appointments, answering the same questions, collecting feedback and sending reminders. They are used in education, restaurants, online stores, logistics, medicine and tourism. A bot can handle many conversations at once and works at night, and complex or sensitive cases still go to a person.

How long does chatbot development take?

We set the timeline after the specification. A script-based bot for one channel without integrations is the fastest option; an AI assistant with a knowledge base, CRM integration, payments and several channels takes longer.

Preparing answers and testing real dialogues takes a large share of the time. Having your FAQ, price list and examples of customer questions ready shortens the project.

What affects the cost of a chatbot

We quote after the specification. The main factors:

number of scenarios and channels;
script-based or AI answers;
integrations with CRM, payments and other systems;
admin panel and analytics needs;
languages and support after launch.

What we need from you

A list of tasks the bot should handle and examples of real customer questions.
Access to channels: Telegram, WhatsApp Business, Viber, Instagram.
Access to CRM and other systems, in test mode first.
A person who approves scenarios and answers.

What you get and how we measure it

We measure the bot by the work it takes off your team:

number of orders, bookings and leads through the bot;
share of questions resolved without a person;
time to first answer;
monthly report with suggested new scenarios.

Why a chatbot is better built by a team

Common problems with bots built quickly:

dead ends in dialogues where users cannot reach a person;
AI answers that invent prices or terms;
leads lost because the CRM integration fails silently;
personal data stored without consent or protection.

Working with a Kyiv team remotely

We work remotely with companies in the UK, the EU and North America: video calls, email, Telegram or WhatsApp, and shared documents for plans and reports. Kyiv is on UTC+2 (UTC+3 in summer), so our working day covers most of the UK and EU business day and the morning on the US East Coast. You get one project manager who is responsible for the timeline.
