Sales and requests
Collecting requests, qualifying a lead, choosing a service or product, passing data to a manager, and automating the first stage of sales.
Telegram bots
Telegram bot development for business
We design and develop Telegram bots around business tasks: sales, request handling, customer support, operations automation, online payments, and integrations with internal systems.
We do not build a set of commands. We create a working tool that can interact with CRM, ERP, databases, APIs, AI models, and an admin panel.
Custom Telegram bot development
Custom Telegram bot development starts with the business task: what the bot must do, which users work with it, which data it receives, where it sends information, and which actions it should automate.
At the design stage we define dialogue scenarios, user roles, integrations, the data structure, error handling, and admin functions. This makes it possible to build a solution that can evolve after launch.
What tasks a Telegram bot can solve
Customer support
Answers to typical questions, request statuses, routing inquiries, and handing complex cases to a staff member.
Online payments
Building a payment scenario, receiving payment statuses, and then changing the state of an order or service.
Personal service in Telegram
User profile, action history, documents, statuses, notifications, and personal functions inside a familiar interface.
Internal processes
Employee notifications, approvals, requests, reports, tasks, and other operational processes of the company.
AI features
Intelligent answers, knowledge-base search, text processing, and automation of part of communications with controlled business logic.
A Telegram bot for business and process automation
A Telegram bot can become a separate interface to the company’s existing information system. The user works in Telegram, while business logic, data, access rights, and integrations stay on the server side.
This approach fits processes where a separate mobile app is not required, but fast access to functions, notifications, requests, statuses, or internal services is.
Telegram bot development for sales
A sales bot can accept inquiries, clarify request parameters, show relevant offers, collect contact data, form an order, and pass information to CRM or a manager.
The scenario should be short and clear: the bot should not force the client through a long survey if the needed data can be obtained later or automatically.
Product and service catalog in a Telegram bot
For some projects the bot can contain a catalog of products or services, categories, cards, quantity selection, order parameters, and passing the result to the order-processing system.
If a full e-commerce product is needed — with a large catalog, a complex SEO structure, and web checkout — the core system should remain the online store, and the Telegram bot an additional interaction channel.

Telegram bot with online payments
A payment scenario can be implemented in the bot through available Telegram mechanisms and/or a payment provider, if this matches the product or service type, the region, and the requirements of the chosen payment system.
It is critical to handle successful payment, cancellation, error, retry, timeout, and asynchronous status changes correctly. Provider secret keys must not live in client-side code.
Telegram bot integration with CRM
Requests, contacts, user replies, statuses, and bot action results can be passed to CRM. With reverse integration the bot can receive data from CRM and show the current status to a client or employee.
Before development it is necessary to define the source of truth for each data type and the synchronization rules, so CRM and the bot do not create conflicting records.
See also: CRM development.
Telegram bot integration with ERP and corporate systems
For internal processes the bot can work with orders, stock, requests, approvals, documents, and other data that live in ERP or a corporate system.
Access to such functions must account for authorization, roles, action audit, and limits on exposing sensitive data.
See also: ERP development and corporate systems.
Telegram bot integration with APIs and external services
The bot can receive and send data through APIs: CRM, ERP, payment services, delivery systems, databases, analytics platforms, and internal backend services.
Integration modules must include error handling, logging, timeouts, and retries where the business logic allows it.
AI bot in Telegram
A Telegram bot can be extended with AI features: answers from an internal knowledge base, request classification, extracting data from messages, summarization, and help for employees or clients.
For business scenarios it is important to constrain the model with context, user rights, and allowed actions. Critical operations must not run from free text alone without validation and business rules.
If RAG is used, knowledge sources, access rights, index updates, and answer tracing must be designed separately.

Telegram Mini App as a bot extension
If the scenario becomes more complex than a regular dialogue, part of the interface can be implemented as a Telegram Mini App: forms, catalog, account, tables, parameter selection, and other web interfaces inside Telegram.
In such a project the bot handles communication and starting the scenario, and the Mini App handles the more complex visual interface. Architecture should provide unified authorization and a shared backend.
Managing a Telegram bot
A business bot may need an admin panel: users, requests, content, broadcasts, directories, scenarios, statuses, analytics, and integration settings.
If the admin part is complex, it should be designed as a separate web application with roles and server-side authorization, rather than trying to move all management into Telegram commands.
See also: web application development.
Notifications via Telegram
The bot can send system notifications about orders, statuses, tasks, payments, and events. For mass messages it is necessary to account for Telegram Bot API limits and the business rules of user subscription.
Service notifications and marketing broadcasts should be separated logically so the user can manage subscriptions where needed.
If you need a bot for a website and other channels: chatbot development.
Authorization, roles, and data protection
Telegram user_id cannot be treated as a sufficient security mechanism for every scenario. Access to corporate data may require additional account binding, a one-time code, SSO, or another identity confirmation method.
- Store the bot token only in server environment variables or a secrets manager.
- Do not write tokens, API keys, or secrets into the frontend bundle, git repository, or public config.
- Check user permissions on the server before returning data or performing an operation.
- Log critical actions without leaking sensitive data.
- Separate production and staging credentials.
Solution architecture
The SEO website itself remains Next.js. The Telegram bot does not have to live inside the Next.js application: the bot backend should match the project architecture and load requirements.
For production, a webhook on an HTTPS endpoint is usually used. Long polling is acceptable for local development or simple internal tasks if it matches the project infrastructure. The webhook endpoint must validate incoming updates, respond to Telegram quickly, and not block on long operations. Heavy tasks should be moved to a background job when needed.
For payments, order creation, passing a request to CRM, and other critical operations, repeated event delivery must be taken into account. The operation should be idempotent where a retry could create a duplicate. External API errors should be logged in a structured way. The user should see a clear message without a stack trace or technical details.
As load grows, architecture should allow scaling handlers without losing events. The synchronous Telegram response and long integration operations should be separated in advance if the project requires it. Scaling is designed from real traffic, SLA, and process criticality.
A Telegram bot is one of the directions of our software development.

Analytics and events
For a commercial bot it is useful to record key events: start, scenario choice, sending a request, moving to payment, successful payment, handover to a manager, and completion of the target action.
Events should have stable names and, if needed, be passed into the company’s existing analytics. Extra personal data must not be collected only for statistics.
Telegram bot development stages
01
Task analysis
We define the business goal, users, scenarios, integrations, data, constraints, and target actions.
02
Logic design
We form a dialogue map, states, roles, data model, errors, and integration architecture.
03
Scenario prototype
We verify the key user path before full development, to remove extra steps and disputed scenarios.
04
Backend and bot development
We implement Telegram Bot API, business logic, the database, authorization, integrations, and admin functions.
05
Integrations and testing
We check CRM/ERP/API, payments, errors, repeated events, roles, and the main user scenarios.
06
Launch and evolution
After launch we analyze real scenarios and add new functions and automation without breaking the stable part of the product.
Telegram bot development cost
The cost of Telegram bot development depends on the number of scenarios, integrations, roles, payment logic, the admin panel, AI features, and infrastructure requirements.
A simple bot with a few fixed scenarios and a complex system with CRM, payments, a personal account, and AI are different products in scope. The final estimate is therefore formed after analyzing requirements and defining the first-version composition.
