The administrator answers in messengers all day long
“How much does it cost”, “is there time on Saturday”, “where are you located”. The same questions dozens of times a day.

How long does it take to do the same thing?
Clients forget about the appointment
Empty windows in the schedule because no one reminded a couple of hours before the visit.
Payment is verified using screenshots
Transfer to card, screenshot to chat, manual verification. The order is waiting for someone to look at the statement.
Mailings manually or not at all
Promotions and news do not reach customers who have already purchased.

Demo
Sign up for a barbershop through a bot
Demo of a fictional barbershop: on the left is the client’s chat, on the right is what the owner sees. Complete the registration before payment and send the newsletter to clients.
- Record in a minute: service, master, date and free time with buttons
- Prepayment directly in Telegram and reminder before the visit
- The owner immediately sees the new entry and prepayment in his dashboard
- The mailing to all clients from the panel is sent to the chat in seconds
- Answers to frequently asked questions without an administrator
The data in the demo is fictitious. Your version is built for your process and your data.
What our bots are already doing for their owners
17+ of our bots work for clients. There are six different tasks here - find one similar to yours: the card shows what happened before the bot and what it is doing now.
24/7payment and issuance of tickets without the participation of the owner
Tickets are sold on Telegram without correspondence and payment screenshots
- Before
- Places were agreed upon in correspondence, payments were verified using screenshots. One place could be sold twice, and the partners’ interest was calculated using a calculator.
- After
- The buyer selects a seat on the hall map, pays and receives a ticket via Telegram
- There are no double sales: the choice is based on a live map of the hall
- The bot calculates percentages for partners and freezes them until the event date
A good fit if clients choose a place or time in correspondence, and you check the payment using screenshots
Python, Aiogram 3, Vue 3 Mini App, SQLite
Read the project story3payment methods directly in Telegram: card, bank transfers, digital wallet
The subscription is sold and renewed by itself
- Problem
- Selling a VPN manually means checking receipts, issuing keys, and remembering who needs to renew. For hundreds of clients, this means night shifts at the telephone.
- What we built
- The payment is completed - the client has the key in seconds
- The renewal is written off automatically, the client does not need to do anything
- Not renewed - access is closed automatically
A good fit if you sell access by subscription and monitor who needs to renew
Python, AIogram, FastAPI, MySQL, payment gateway
Read the project story0The manager transfers requests from Telegram to CRM manually
An application from a bot itself becomes a deal in CRM
- Before
- The manager copied requests from the chat into CRM manually. Some leads did not reach the CRM; some were answered within a day, and it was unclear what advertisement brought them.
- After
- The client fills out the form in the Mini App, the deal with the advertising source is created automatically
- While the manager is busy, the bot guides the client with a chain of 7 messages
- The manager responds to the client directly from the CRM card
A good fit if applications arrive in Telegram, and the manager manually transfers them to CRM
Python, Aiogram, PHP, CRM API, Mini App
Read the project story8h/2dthe bot writes again if the candidate is silent
The first correspondence is conducted by AI, the manager only makes a decision
- Before
- The manager corresponded with candidates for hours, 80% of conversations were the same script. I collected the questionnaire from answers at random, and I simply didn’t have time to answer someone.
- After
- AI corresponds from the agency's live account and collects a profile
- The manager receives a card with the buttons “Approve”, “Refuse”, “Additional request”
- The candidate receives the conditions only after the approval of the manager
A good fit if the manager asks the same questions in correspondence all day and collects answers by hand
Python, Telethon, Aiogram, LLM, Google Calendar
Read the project story30training days come on their own, without the participation of the author
The course arrives one lesson per day and cannot be forwarded.
- Before
- Each customer must be given a workout per day, strictly in order. With your hands, this is a shift without days off, and the purchased video can be sent to anyone.
- After
- Paid on the website - the access code is sent to your email
- On the 31st day, access is closed, the bot deletes workouts from the chat
- Lessons and videos are edited by the author in the admin panel of the bot, without a programmer
A good fit if you sell a course or lessons by subscription and do not want them to be forwarded
Python, Aiogram, FastAPI, APScheduler, Tilda
Read the project story4rate source: one fell - the exchange continues to work
The client himself calculates the exchange amount and leaves a request in Telegram
- Before
- The exchange rate was taken from one source: it went down - the exchange got up. The amount was calculated using a calculator, and the details were asked several times in the chat.
- After
- The client enters the amount in local currency and immediately sees the total in USDT with his discount
- Bonuses for invitees and discounts on the course are awarded automatically
- Applications go to Google Sheet, and the admin learns about each new one.
A good fit if the client waits in chat while you calculate the price and place an order
PHP, Mini App, MySQL, Google Sheets API

What is important to know about the development of Telegram bots
When you really need a bot
A bot pays off when a business has a repeating task with a clear algorithm: accepting applications and recording, selling courses and subscriptions, answering frequently asked questions, sending out segments, transferring data to CRM. The client receives a response or product immediately, without waiting for an administrator.
If you need a complex interface - a catalog with filters, a shopping cart, choosing a seat in the hall - we do it Telegram Mini App. This is a web application that opens directly in Telegram without installation.
What integrations are possible?
The bot connects to almost any service with an API. Most often this payment (payment gateway, bank transfers, payment gateway, CryptoPay), CRM (CRM, CRM), tables (Google Sheets, Notion), AI models (GPT, Claude, Gemini) and your internal systems via REST or webhooks.
How long does development take?
A simple bot with a menu, answers to questions and applications - 5–7 days. Bot with database, payment and admin panel - 10–14 days. Product with Mini App, AI and roles - 3-5 weeks. The deadlines are realistic if you answer questions quickly and watch intermediate demos.
How does a working bot differ from a surrendered one?
A bot that simply responds to commands is half the job. We rent from fall monitoring, database backups, activity log, Telegram API error handling (FloodWait, temporary failures) and spam protection. Without this, the bot crashes when the load increases and loses data.

What customers say
Reviews from past projects, verbatim.
I'm very pleased with the execution. The bot turned out exactly as described. In addition, after the first submission, I also asked to make additional changes - everything was done. And everything was decorated well, although I did not give any requests or instructions regarding the design. Thanks a lot!
The developer did an excellent job with an urgent project: he developed a Telegram bot with Google Sheets integration quickly and efficiently. He was constantly in touch, suggested improvements and promptly made changes. Professionalism and flexibility, communication as comfortable as possible. I recommend it to anyone who values speed and reliability.
Pleased with the cooperation! Everything was done, always in touch. Installed the bot remotely through my desktop, at my request. Thank you
Frequently asked questions
How much does a bot cost for my task?
The prices in the tariffs are starting. The result depends on the number of scenarios, integrations and complexity of the logic. After a short brief, we send a fixed estimate and deadline in days. It's free.
How quickly do you launch?
A simple bot - 5-7 days, a bot with payment and admin - 10-14 days, Mini App with AI - 3-5 weeks.
What's included in support?
Monitoring around the clock (if the bot crashes, we’ll be the first to know), database backups, minor edits, library updates, failure response within an hour during business hours. Major new features are priced separately.
What do you write on?
Python and aiogram for bot logic, PHP for web admins and Mini App backends. MySQL, PostgreSQL or SQLite databases. We choose according to the task.
Who owns the code?
To you. We transfer the sources to a repository that you control and document the important parts. You can develop further with us or with another developer.
Can you modify someone else's bot?
Yes, if you have the sources. First, an audit Quote on request: we evaluate the code and the cost of modification. If the code is really bad, let’s be honest, it’s cheaper to rewrite it.
