What We Build for Travel & Tourism
Booking engines, hotel PMS, GDS integration, tour operator software, travel CRM, dynamic pricing, mobile apps, and corporate travel management — the complete travel tech stack.
Online Booking Engine & OTA Platform
Custom OTA development — multi-product booking engine (flights, hotels, car hire, packages, activities), real-time availability search, dynamic packaging, itinerary builder, mobile-first booking flow, multi-currency and multi-language, GDS/NDC integration, payment gateway, post-booking management, and agent portal. Built for conversion at scale.
Hotel & Property Management System
End-to-end hotel PMS — reservations management, front desk operations, housekeeping scheduling, room inventory and rate management, guest profile CRM, group booking management, channel manager integration (SiteMinder, RateGain, Cloudbeds), OTA connectivity (Booking.com, Expedia, Airbnb), revenue reporting, and finance module. Cloud-native and mobile-accessible.
Tour Operator & DMC Software
Tour operator management platform — product catalogue (tours, excursions, transfers, accommodations), itinerary builder with day-by-day schedule, supplier and contract management, group booking and passenger manifest, real-time availability, B2B agent booking portal, commission management, voucher generation, and customer-facing booking website with live inventory.
GDS & Travel API Integration
Third-party travel API integration — Amadeus Travel APIs (NDC, IATA), Sabre Web Services, Travelport (Galileo, Worldspan), hotel channel managers, car rental APIs (Hertz, Avis, Enterprise), cruise line APIs, activities/excursions (Viator, GetYourGuide, Rezdy), transfers, and insurance APIs. Custom aggregation layer normalising multi-supplier responses into a unified booking flow.
Dynamic Pricing & Revenue Management
AI-powered pricing engine — demand forecasting, competitor rate monitoring, yield management rules, seasonal pricing automation, last-minute deal engine, package pricing optimisation, channel-specific pricing strategies, and real-time revenue dashboards. Integrates with PMS, OTA channels, and booking engines to maximise RevPAR and package margin.
Travel CRM & Loyalty Platform
Travel-specific CRM — 360-degree customer profile (booking history, preferences, loyalty tier), automated pre-travel and post-travel communication workflows, loyalty points engine (earn/burn), tier management (Silver/Gold/Platinum), partner programme integration, customer satisfaction surveys, win-back campaigns, and a B2C app with digital loyalty card.

Travel Technology Clients
OTAs, hotel groups, and tour operators across the UK, AU, and US on building travel platforms with 1Solutions.
1Solutions built our OTA platform from scratch — flight and hotel search, GDS integration (Amadeus + SiteMinder), booking flow, payment, and a mobile app. The MVP was live in 14 weeks and we processed our first booking in week 15. 18 months later the platform does $4M monthly GMV. Their travel domain knowledge was as valuable as their technical skill.
We were running our hotel group on a 12-year-old PMS that couldn't integrate with OTAs. 1Solutions built a modern cloud PMS with SiteMinder channel manager integration, a direct booking engine, and a loyalty app. RevPAR increased 28% in the first year as direct bookings went from 18% to 41% of revenue. Exceptional travel technology expertise.
We hired 1Solutions to build the booking platform for our adventure travel brand — tour packages, activity booking, transfers, and accommodation, all bookable in one flow. They integrated Viator for activities and built a custom tour operator back-end for our team. Platform launched in 5 months. Our online booking conversion rate is 6.2%, above industry average.

GDS & Travel API Specialists
Amadeus, Sabre, Travelport, NDC airline APIs, hotel channel managers (SiteMinder, RateGain), and activities APIs (Viator, GetYourGuide) — deep integration expertise across the travel API ecosystem.
Conversion-Optimised Booking Flows
Our travel UX team designs booking flows validated against industry benchmarks. We track and improve search-to-booking conversion rate as a primary KPI, not just feature delivery.
Multi-Currency & Multi-Language
All travel platforms we build support multi-currency pricing, FX rate updates, and multi-language content — critical for travel companies with international customer bases.
Mobile-First Development
Every travel platform is built mobile-first. Native iOS and Android apps or high-performance React Native — with offline itinerary access, push notifications, and mobile payment.
PCI-DSS Compliant Payment Integration
Payment security is non-negotiable in travel. All platforms include PCI-DSS compliant payment integration, 3DS2/SCA implementation, and fraud detection for card-not-present transactions.
AI-Powered Pricing & Personalisation
Dynamic pricing engines (yield management, demand forecasting, competitor monitoring) and personalisation engines (recommendation, content, email) increase revenue per booking and repeat rate.
Post-Launch Support & SLAs
Travel platforms cannot go down during peak booking periods. We offer SLA-backed post-launch support with P1 response under 2 hours, proactive monitoring, and on-call DevOps during peak seasons.
