Karmann's — Custom Booking Module Replacing Travelline
Complete replacement of Travelline for a Forbes Top-50 hotel: a custom booking engine, channel manager with 5 OTA platforms, PMS integration, and guest personal account. The project everyone was afraid to start — that paid for itself in the first year.
Challenge
The Client's Challenge
The hotel was paying a large annual commission to Travelline and wanted to break free from that dependency — but the task was daunting. Several teams had attempted a custom booking module before, burning budget and time before returning empty-handed. What was needed wasn't just an alternative — it had to be a production-ready system that worked reliably without losing a single booking.
Karmann's is a Forbes Russia Top-50 hotel, the best in the Kaliningrad region. High traffic, demanding guests, complex business logic: bookings via the hotel's own site, five OTA channels, and a PMS — all simultaneously. Any bug in the engine means a lost booking and reputational damage. That risk had stopped every previous attempt.
Solution
What We Built
We built a complete booking system from scratch: a client-facing widget, a booking engine, a channel manager with five OTA platforms, and a guest personal account. The quality criterion: 100% booking delivery from any channel into the PMS. We also optimized the user flow — reducing steps in the booking process, which directly impacted conversion.
Key Features
- Client booking widget: optimized flow, fewer steps, higher conversion
- Channel manager: sync with 5 OTAs — Yandex.Travel, Ostrovok, OneTwoTrip, AkademOnline, Bronevick
- PMS Logus integration: all bookings hit the hotel management system in real time
- Guest personal account: change dates, add services (transfer, spa, etc.), manage booking details
- Notification module: booking confirmation, pre-arrival reminder, change notifications, post-checkout email
- Payment module: YooKassa and Robokassa integration
- Hotel admin panel for rate, availability, and reporting management

“Honestly, we were afraid to enter this project. The budget was serious, and experience from industry peers suggested the task might be unsolvable — several teams had tried, spent money and time, and come back empty-handed. But Frog Studios convinced us they could do it — and they really did. The module runs reliably, bookings go through without losses. Looking back, that decision was absolutely the right one.”
