Telegram Mini App & Bot Development Company

Reach Your Users Where They Already Are

Two billion people use Telegram. Bots and Mini Apps let you deliver services, handle support, run workflows, and collect payments inside the app your customers already have open — without asking them to download anything new. CimpleO builds Telegram bots and Mini Apps that do real work, not just send automated messages.

Telegram Bot Development

Custom bots for customer support, order tracking, appointment booking, notifications, and internal team workflows. We build with Python (python-telegram-bot), Node.js, or PHP depending on your stack, with proper webhook handling, conversation state management, and inline keyboard UX that doesn’t confuse users. Production-hardened with error handling and rate limit compliance.

Telegram Mini Apps

Mini Apps run inside Telegram with a full web interface — your own UI rendered in a bottom sheet within the app. We build Mini Apps for eCommerce storefronts, service booking, loyalty programmes, and interactive tools. Telegram’s native payment API is available inside Mini Apps, making checkout fast for users without leaving the messenger.

System Integration

A Telegram bot is only as useful as the systems it connects to. We integrate bots with your CRM, support helpdesk (Zendesk, Freshdesk), e-commerce platform, warehouse management system, or internal database. Real-time order status, support ticket management, inventory queries — all accessible by your customers or team without leaving Telegram.

Internal Operations Bots

Your team is in Telegram already. We build internal bots that surface business data, trigger workflows, send alerts, and handle routine requests without employees switching to another system. Sales reports, infrastructure alerts, approval flows, lead notifications — delivered to the channel your team actually monitors.

Why Telegram Is Worth Investing in Now

Zero installation friction — users engage instantly, no app store, no account creation
Native payments — Telegram Pay supports card payments inside bots and Mini Apps in supported markets
High open rates — bot messages are read at 5–10× the rate of email notifications
Telegram identity — phone-verified user accounts available by default, no registration forms
Scalable infrastructure — Telegram handles delivery at any volume, you handle the logic

How We Build Telegram Projects

1. Scope call (30 min). We define what you’re building, who uses it, and what systems it connects to. At the end you have a fixed-price quote and a realistic timeline.

2. Architecture and API design. Before writing application code, we map the bot conversation flow or Mini App screens, design the backend API, and confirm the Telegram API capabilities required — including Telegram Pay eligibility for your geography.

3. Development in 2-week sprints. You see working software every two weeks, not just status updates. Most Telegram bots reach a working prototype in the first sprint. Mini Apps take 2–4 sprints depending on complexity.

4. Testing on real devices. Telegram’s rendering on iOS, Android, and desktop differs enough to require explicit QA on each. We test on actual devices before delivery, not just the desktop web client.

5. Deployment and handoff. We deploy to your server or cloud (AWS, GCP, Hetzner), set up monitoring, document the codebase, and hand over Telegram Bot API credentials and webhook configuration. Post-launch support included for 30 days.

Tech Stack

Bots: Python (python-telegram-bot, aiogram) for conversational bots; Node.js for integration-heavy projects with existing JS backends
Mini Apps: React or Vue frontend, served over HTTPS, communicates with your backend via Telegram’s initData for user authentication
Payments: Telegram Bot API payments for Telegram Pay; Telegram Stars for digital goods
Backend: NestJS, FastAPI, or Laravel depending on client stack
Hosting: VPS (Hetzner, DigitalOcean), or your existing cloud infrastructure

Who Builds Your Project

A senior engineer leads every Telegram project — not a junior developer following a template. Our team has shipped Telegram Mini Apps and bots for eCommerce, fintech, logistics, and B2B internal tooling. We’ve handled Telegram API changes, payment integration edge cases, and Mini App performance on low-end Android devices.

If you need a Telegram Mini App developer on a longer engagement — retainer or dedicated resource — we offer that too. The developer works in your codebase, attends your standups, and is accountable to your PM. See Hire Telegram Developers for engagement models and rates.

Frequently Asked Questions

How long does it take to build a Telegram bot?

A basic Telegram bot (notifications, simple command flows, webhook integration): 1–2 weeks. A bot with complex conversation state, CRM integration, and admin panel: 3–5 weeks. A Telegram Mini App (web UI inside Telegram): 4–8 weeks depending on feature complexity. We scope and deliver fast — Telegram projects are among our shortest timelines.

What is the difference between a Telegram Mini App and a Telegram bot?

A Telegram bot responds to commands and sends messages in a chat — text, buttons, files. A Telegram Mini App is a full web application that opens inside Telegram as a bottom sheet, with its own UI, navigation, and forms. Bots are simpler to build and cover most notification, support, and workflow use cases. Mini Apps are better when you need a storefront, booking form, loyalty dashboard, or anything that benefits from a real interface rather than a chat flow. We build both, and often combine them — Mini App for the user interface, bot for the messaging and notifications.

What can a Telegram Mini App do that a regular website can't?

Mini Apps live inside Telegram — no app download, no account creation, instant access from a chat button. Users pay with Telegram Pay (card details already stored). They get the Telegram identity (username, phone verification) automatically. Retention via bot messages is 5–10× higher than email. For audiences already on Telegram, it removes more friction than a mobile app.

Can you integrate a bot with our existing CRM or support system?

Yes. We've integrated Telegram bots with Zendesk (ticket creation, agent handoff), Freshdesk, HubSpot, and custom internal systems. Customer messages in Telegram become support tickets; ticket updates send Telegram notifications. Bidirectional sync available.

How much does Telegram Mini App development cost?

A simple notification or info bot: $3,000–$8,000. A bot with CRM integration, conversation flows, and admin panel: $10,000–$25,000. A full Telegram Mini App with storefront, payments, and backend: $20,000–$50,000. These are real project numbers — scope drives cost more than time. We give a fixed-price quote after a 30-minute scoping call.

Who builds our Telegram Mini App at CimpleO?

A senior engineer leads the project — not a junior handed a tutorial. Our Telegram team has delivered Mini Apps, bots, and Telegram Pay integrations across eCommerce, fintech, logistics, and internal tooling. If you're hiring Telegram Mini App developers on a contract basis, we also offer retainer engagements where a dedicated engineer works in your stack.

Do you support Telegram Stars and Telegram Pay?

Yes. We implement Telegram's native payment API (Telegram Pay) for card payments inside bots and Mini Apps. Telegram Stars for digital goods. Available in supported markets — we check coverage for your geography before committing.

Can you build a Telegram Mini App for an audience outside Russia?

Yes. Telegram is a global platform — our clients span Southeast Asia, the Middle East, Europe, and the Americas. Telegram Pay availability varies by market; we verify this upfront. The underlying technology (Mini App API, bot API) works identically everywhere.
