1The Problem
Barista Sri Lanka's front-counter model was creating significant queue bottlenecks during peak hours — particularly during morning coffee rushes and lunch periods. Staff were manually processing orders, taking payments, and calling out order numbers, which meant queues regularly stretched to 8–12 customers at busy outlets. Management needed a solution that could handle order-taking and payment autonomously, while keeping inventory synchronised across all outlets in real time.
2What We Built
HadesReality designed and deployed a fully branded self-service kiosk platform across 10+ Barista outlets. The system features a touchscreen ordering interface customised to Barista's menu structure, integrated payment gateways (card, QR code, and e-wallet), and a real-time inventory sync engine that pushes stock updates to a centralised back-office dashboard the moment an item is ordered. Orders are routed directly to the kitchen display system, eliminating the manual relay between front-of-house and baristas.
3Key Technical Decisions
We chose a React-based frontend for the kiosk UI to keep the experience smooth and rebrandable, backed by a Node.js + PostgreSQL stack for the order management layer. WebSockets handle real-time inventory updates, ensuring stock levels are accurate across all outlets with under one-second propagation delay. The system was built offline-first — if internet connectivity drops, the kiosk continues taking orders and payments, syncing when reconnected.
4Results
Since deployment, Barista Sri Lanka has seen an estimated 40% reduction in average queue wait time during peak hours. All 10+ outlets went live on the same day with zero critical incidents. The back-office team now manages menu updates, pricing, and promotions from a single dashboard — a change that previously required manual updates at each outlet individually.
5What This Means for Your Business
If you operate a multi-outlet F&B or retail business and your front-counter is a bottleneck, a self-service kiosk system can materially improve throughput, reduce labour dependency, and give you real-time visibility across every location. The investment typically pays back within 6–18 months in reduced queue loss and labour savings.
