Travel UK

A corporate travel app for booking UK trains, flights, and hotels with live platform alerts and automatic receipts.

CASE STUDY EXECUTIVE SUMMARY
Official PLEXA Production Release

How Did PLEXA Engineer the Travel UK Solution?

Travel UK is a corporate travel management application built for companies whose employees travel regularly across the United Kingdom. PLEXA designed and engineered a cross-platform mobile application on iOS and Android alongside a centralized web administration portal using React Native, TypeScript, Node.js, and live UK National Rail transit data feeds. The platform consolidates UK train schedules, domestic flight routes, and hotel reservations into a single 60-second booking flow with corporate billing and automated VAT expense invoice generation. By replacing fragmented third-party booking websites with live platform delay alerts, offline digital ticket wallets, and automatic accounting software synchronization, Travel UK reduced corporate expense filing time by 50 percent. PLEXA delivered the complete application in three weeks with custom role-based approval workflows, corporate spending policy enforcement, and 100 percent client intellectual property ownership.
