Cases in production

Cases of Telegram bots: 18 projects with task and result

We divided projects according to business objectives. Each card contains what happened before the launch, what happened and who would benefit from the same solution. 7 projects were analyzed in detail.

Sales on Telegram

The buyer selects and pays without leaving Telegram

The catalogue, hall layout and payment are opened directly in the chat. The owner sees orders in the admin panel.

24/7payment and issuance of tickets without the participation of the owner

Client projectEvent tickets

Tickets are sold independently, the same seat will not be sold twice

Before
Places were agreed upon by correspondence, reservations were entered in a table, and payments were verified using screenshots. One place could be sold twice; the partners calculated the percentages on a calculator.
After
  • The buyer selects a seat on the hall map in the Mini App and pays immediately
  • Interest is accrued to partners themselves and is frozen until the date of the event.
  • The owner changes events, prices and interest in the admin panel without a developer

A good fit if you sell tickets or seats through partners and calculate their percentages manually

  • The renewal is written off automatically; non-payers are automatically denied access.
  • You can buy in a bot or on a website with a personal account
