Event Ticketing Platform with Interactive Seating
A large-scale ticketing ecosystem with interactive seating plans, mobile scanner apps, admin dashboards, and white-label support — serving major theaters across Austria.
Challenge
Entrello needed to build a comprehensive ticketing ecosystem for major theater venues. The system required interactive seating plans for halls of different sizes, a mobile app for ticket scanning at entrances, a desktop box office app, an admin dashboard for venue managers, and white-label deployments for partner organizations — all working together seamlessly.
Solution
We architected a multi-application platform: Next.js customer-facing website with interactive seat selection via Konva.js, a Capacitor-based Android scanner app for venue staff, an Electron desktop app for box office, and a full admin dashboard. The backbone is a comprehensive GraphQL API handling complex seating configurations, Stripe payment processing, QR code ticket generation, and white-label multi-tenancy. Playwright E2E testing ensures reliability across the entire ecosystem.
Results
The platform serves major Austrian theater venues. The interactive seating plan system became a key selling point, noticeably reducing support inquiries about seat locations. White-label architecture enabled rapid partner onboarding without additional engineering effort.
The Team
Technology Stack
"Their GraphQL implementation was impressive — over 4,800 lines of schema, and it all works smoothly. They also set up Playwright testing, which gives us confidence with every release."
