Booking engines & PMS
Direct booking engines, PMS, CRS and channel managers with rate, inventory and stop-sell logic tested at peak load.
Industries GDPR PCI DSS
YuSMP Group builds travel and hospitality software for US and EU airlines, hotels, OTAs, tour operators and ground-mobility brands. We engineer booking engines and PMS, OTA and GDS integrations with Amadeus, Sabre and Travelport, IATA NDC level-3 and level-4 channels, loyalty and ancillary upsell, native mobile concierge apps, revenue management and dynamic pricing, plus operations and housekeeping platforms. PCI DSS scope stays minimal, PSD2 SCA stays optimized, and IATA NDC plus OpenTravel schemas wire in cleanly.
Our travel and hospitality practice serves four buyer profiles: airlines and ground-mobility operators integrating GDS, NDC and direct distribution; hotel groups and short-stay platforms modernizing PMS, CRS and channel management; OTAs and tour operators building booking flows across multi-supplier inventory; and loyalty and ancillary teams squeezing more value from each booking. We deliver under PCI DSS v4.0 for the payment surface, PSD2 SCA for EU card flows, GDPR for traveler data, APIS for cross-border passenger info and DOT 14 CFR Part 399 for US air consumer protection. IATA NDC and OpenTravel Alliance schemas anchor the data model. Explore how we deliver this through our Mobile App Development service.
What we build
Direct booking engines, PMS, CRS and channel managers with rate, inventory and stop-sell logic tested at peak load.
Amadeus, Sabre, Travelport plus IATA NDC level-3 and level-4 carrier connections and OpenTravel hotel content.
Tier, points and partner integrations plus seat, bag, room and experience ancillary bundling along the funnel.
Native iOS and Android apps with mobile check-in, digital key, in-property service requests and offline support.
Demand forecasting, competitive rate shopping, BAR and fence management, ancillary price elasticity modeling.
Housekeeping, maintenance, F&B and shift platforms with mobile-first UX for line staff and offline tolerance.
Segments
Travel is not one market. A low-cost carrier fighting for NDC direct-connect share, a boutique hotel group replacing a legacy PMS, and an OTA reconciling multi-supplier inventory each need a different data model, payment posture and peak profile. We map the segment first, then engineer to its economics.
Direct booking and NDC offer-and-order platforms, ancillary merchandising, interline and codeshare handling, disruption re-accommodation and APIS filing. We wire Amadeus, Sabre and Travelport alongside level-3 and level-4 NDC connections, so you keep distribution reach while moving share to lower-cost direct channels.
PMS, CRS and channel-manager modernization with rate, availability and stop-sell logic that survives OTA parity checks. We integrate SiteMinder, Cloudbeds, Mews and Opera-class systems, add mobile check-in and digital key, and keep housekeeping and F&B operations working offline in weak-signal parts of the property.
Multi-supplier aggregation, cache and de-dup logic, price accuracy monitoring and look-to-book optimization at high query volume. We build the search-and-book funnel to hold conversion under load and reconcile inventory across GDS, bedbank and direct-supplier feeds without double-selling.
Dynamic packaging that bundles flights, accommodation, transfers, activities and insurance into a single checkout, plus supplier dashboards and margin control. We handle EU Package Travel Directive obligations — combined-price display, insolvency protection and refund handling — inside the booking flow rather than bolted on later.
Marketplace and property-management platforms with iCal and OTA calendar sync, damage-waiver and deposit flows, guest verification and dynamic nightly pricing. We keep availability consistent across Airbnb, Booking.com and direct channels so oversell and calendar drift stop eating margin.
Self-service car, boat and equipment rental with QR unlock, real-time availability and in-app payments across jurisdictions, plus cruise and experience booking. We build for repeat-booking retention and cross-border payment acceptance, the two levers that decide unit economics in these segments.
Technology
We standardize on a proven, boring-by-design stack so travel platforms stay maintainable long after launch — and integrate the industry middleware and payment rails that make distribution and conversion work in production.
React and Next.js front ends, Node.js, Python, Java and .NET services behind an API gateway. Event-driven cores (Kafka, SQS) absorb burst load from search and booking spikes without dropping transactions.
Native Swift and Kotlin plus React Native for cross-platform, with offline-first sync for check-in, digital key and in-property service where connectivity is weak.
Amadeus, Sabre and Travelport APIs, IATA NDC level-3 and level-4, OpenTravel Alliance schemas, channel managers (SiteMinder, Cloudbeds) and PMS/CRS connectors behind a normalized anti-corruption layer.
PSP tokenization (Stripe, Adyen, Braintree), 3DS2 with risk-based SCA exemptions, PCI DSS v4.0 scope minimization and a hardened secrets vault. PAN never lands in application code.
A cloud data warehouse (BigQuery, Snowflake), demand forecasting and rate-shopping pipelines, and ML models for BAR, fence and ancillary elasticity feeding your pricing engine.
AWS and GCP with seasonality-aware autoscaling, blue-green releases, schema-drift monitors for GDS/NDC feeds and full-stack observability so holiday peaks stay uneventful.

Why YuSMP
Engineers who have shipped against Amadeus, Sabre, Travelport and direct NDC — not learning the schemas on your timeline.
Seasonality-aware scaling, schema-drift detection and chaos drills so summer surge and holiday peaks stay uneventful.
Every release ships with auth-rate, look-to-book and ancillary attach deltas, not just velocity charts.
GDPR-aligned · CCPA-acknowledged · PCI DSS scope-minimization · PSD2 / 3DS2 · ISO 27001 ready · SOC 2 Type II in progress.
A tour builder that handles flights, accommodation, and activities in a single checkout is genuinely hard to get right. YuSMP built the bundling engine, supplier API integrations, and a UX that our travellers complete without abandonment. Booking completion is 71%, versus a 45% industry baseline.
Self-service boat and catamaran rental requires real-time availability, damage waivers, and payments that work across jurisdictions. YuSMP built a mobile platform that handles all of it. We launched in two marinas and expanded to five within three months of going live.
FAQ
Yes. We integrate Amadeus Self-Service and Enterprise APIs, Sabre Dev Studio and Travelport Universal API, plus IATA NDC level-3 and level-4 connections directly with carriers. We also bridge to OpenTravel Alliance schemas for hotel content.
We tokenize card data via the PSP, keep PAN out of our applications and host payment fields in iframe or redirect mode where the regulator and conversion allow. The PCI audit boundary stays around a thin, well-instrumented zone.
Yes. We deliver demand forecasting, competitive rate shopping, fence and BAR management, ancillary bundling and upsell modeling — integrated with PMS, CRS and channel managers.
We implement APIS / Advance Passenger Information for cross-border carriers, plus DOT 14 CFR Part 399 compliance for US air — full-fare advertising, 24-hour hold and refund rules, tarmac delay handling.
Yes. We implement 3DS2 with risk-based exemptions for low-value and MIT transactions, route by issuer-country to maximize auth rate and provide regulator-grade evidence for fraud chargebacks.
We deliver native iOS and Android apps with mobile check-in, digital key, ancillary upsell, loyalty redemption, push re-engagement and offline support for in-property areas with weak connectivity.
Airlines and air carriers, hotels and resorts, OTAs and metasearch, tour operators and DMCs, vacation and short-stay rentals, and ground-mobility, rental and cruise operators. We map the segment's data model, payment posture and peak profile before we architect, because a carrier, a hotel group and an OTA each need a different platform.
Yes. We connect channel managers such as SiteMinder and Cloudbeds, and PMS/CRS platforms including Mews, Cloudbeds and Opera-class systems, behind a normalized anti-corruption layer. Rate, availability and stop-sell logic is tested against OTA parity checks so you do not oversell or drift out of sync.
We architect event-driven cores that absorb search-and-booking bursts, run seasonality-aware autoscaling on AWS or GCP, and rehearse peak load before launch. Schema-drift monitors watch GDS and NDC feeds, and we run chaos drills so summer surge and holiday peaks stay uneventful.
Yes. We build dynamic packaging that bundles flights, accommodation, transfers, activities and insurance into one checkout, with supplier dashboards and margin control. EU Package Travel Directive obligations — combined-price display, insolvency protection and refund handling — are built into the booking flow, not bolted on afterward.
A focused MVP — a single booking flow with one distribution source and a payment provider — typically ships in three to four months. We start with a two-week fixed-scope discovery to map channels, inventory and payment posture, then deliver in two-week increments behind feature flags with a conversion and auth-rate A/B harness.
React and Next.js front ends; Node.js, Python, Java or .NET services; native Swift and Kotlin or React Native for mobile; Kafka or SQS for event-driven load handling; a BigQuery or Snowflake data warehouse for revenue and forecasting; and AWS or GCP for hosting. We standardize on a proven, maintainable stack rather than novelty.
Yes. We build to WCAG 2.2 AA for accessibility and engineer traveler-data handling for GDPR and CCPA/CPRA — consent, data-subject requests, retention and cross-border transfer controls. The ePrivacy Directive governs cookie and tracking behavior in EU booking flows.
