How we automated 80% of bookings for the CHANGER barbershop chain

CHANGER case study: a Telegram Mini App for a barbershop chain - 80% of bookings without an administrator. How it works and what it delivered.

#04DAROBOTS

In short

  • Darobots automated 80% of bookings for the CHANGER barbershop chain with a full-cycle Telegram booking bot.
  • Average booking time dropped from 8 minutes to 3, repeat visits grew by 35%.
  • Administrator workload fell by 60%: reminders at 24 and 2 hours, rescheduling and cancellations run without a human.
  • The bot syncs with the barbers' Google Calendar and scales across all locations behind one customer-facing interface.

Client and task

CHANGER is a barbershop chain operating in several cities across Ukraine. Before turning to Darobots, administrators handled bookings manually through Instagram Direct and Telegram: each booking meant 5-10 back-and-forth messages. As the chain grew, the system broke down: missed messages, double bookings, lost customers.

Task: automate bookings, reduce the load on administrators, and increase repeat visits.

What the Darobots team did

We built a Telegram bot with a full booking cycle - from choosing a barber to confirming the appointment and sending a reminder the day before the visit.

Dialog demo: this is how the bot works in a real chat

Bot functionality:

  • choice of location and barber;
  • real-time view of available slots;
  • automatic booking confirmation;
  • reminders 24 hours and 2 hours before the appointment;
  • ability to reschedule or cancel a booking without an administrator's involvement;
  • feedback collection after the visit;
  • bonus point accumulation and a loyalty program.

Integrations

The bot syncs with the barbers' Google Calendar, so the schedule is always up to date. New bookings automatically land in the shared log.

–60%workload on administrators

Booking time was cut in half - from 8 minutes down to 3. Repeat visits grew thanks to reminders and the loyalty program, and administrators were freed from routine work to focus on real service.

What matters in this case

CHANGER is a chain, not a single location. Darobots built a single bot that scales across every location: each one has its own schedule and its own barbers, but the customer sees one unified interface. Customers don't need to think about whether they're in Vinnytsia or Kyiv. They just book.
