Travel & Hospitality IT Solutions

Zenkins develops a broad range of travel and hospitality software including: hotel direct booking engines and reservation platforms, property management system (PMS) integration and modernisation, central reservation systems (CRS) for hotel groups, channel management and OTA API connectivity, GDS integration (Amadeus, Sabre, Travelport), revenue management system integration, loyalty programme platforms, guest mobile apps with digital key and contactless check-in, OTA and travel marketplace platforms, airline NDC API development, tour operator and activity booking platforms, travel data analytics platforms, and hospitality SaaS products. We build for hotels and hotel chains, online travel agencies, airlines, tour operators, cruise lines, and travel technology companies.

These three systems form the core of hotel distribution technology and are often confused. A Property Management System (PMS) is the operational core of a hotel — it manages reservations, guest profiles, room assignments, housekeeping, billing, and check-in/check-out at the individual property level. Major PMS platforms include Oracle OPERA, Mews, Cloudbeds, and Agilysys. A Central Reservation System (CRS) sits above the PMS for hotel groups or chains — it provides centralised inventory management across multiple properties, applies chain-wide rate controls, and distributes consolidated availability to all sales channels. A channel manager connects the hotel’s rates and availability (from the PMS or CRS) to the online distribution channels — OTAs like Booking.com and Expedia, metasearch platforms, and GDS systems — ensuring that rate and availability changes are updated in real time across all channels. Zenkins has experience integrating and building all three system types and the API connections between them.

OTA integration follows two main approaches. The first is via a channel manager intermediary — a hotel connects their PMS or CRS to a channel manager platform (SiteMinder, RateGain, Cloudbeds), which then maintains the OTA connections. Zenkins integrates with the major channel manager APIs. The second approach is direct OTA API integration — connecting directly to the Booking.com Connectivity API, Expedia Rapid API, or other OTA’s direct connectivity programme. Direct integration provides lower distribution cost and faster rate update propagation, but requires maintaining each connection separately. Zenkins has delivered both approaches and can advise on the optimal distribution architecture for your property or group’s channel mix. For Indian market distribution, we specifically support MakeMyTrip (MMT) and Goibibo API connectivity alongside global OTAs.

Yes. Zenkins builds hotel direct booking engines with conversion optimisation as a core engineering requirement, not an afterthought. Key elements of a high-converting booking engine include: sub-2-second page load time (meeting Google’s Core Web Vitals thresholds, since page speed directly affects both search ranking and conversion rate), mobile-first checkout flow (60-70% of hotel website traffic is mobile; checkout on mobile is where most abandonment occurs), real-time room availability with accurate pricing (connected live to PMS via API — no cached availability that leads to ‘no rooms available’ errors after guest completes checkout), trust signals at checkout (TLS certificate, payment security indicators, cancellation policy clarity), and A/B tested offer presentation (room type images, package prominence, urgency messaging). We also build the metasearch price feed connectivity that makes direct booking engine rates visible on Google Hotel Ads, TripAdvisor, and Trivago — essential for driving direct traffic.

IATA NDC (New Distribution Capability) is the XML-based data transmission standard that enables airlines to distribute rich offer content — including ancillaries like seat selection, baggage, meals, and lounge access — directly through travel agents and OTAs, bypassing the limitations of legacy GDS EDIFACT formats. NDC allows airlines to create personalised offers based on traveller data and sell ancillary services that legacy GDS systems cannot handle. Zenkins develops NDC APIs for airlines targeting Level 3 and Level 4 NDC certification — covering the Offer creation (AirShopping, OfferPrice, SeatAvailability), Order management (OrderCreate, OrderRetrieve, OrderChange, OrderCancel), and Ticket issuance (OrderTicketing) NDC transaction sets. We also develop NDC aggregator connections for OTAs and travel management companies that need to access airline NDC content.

PCI DSS (Payment Card Industry Data Security Standard) compliance in hospitality is complex because payment card data flows through multiple systems — booking engine, PMS, POS, and potentially call centre — and hospitality businesses have historically been a high-value target for payment card data breaches. Zenkins builds PCI DSS compliance into system architecture from the start. Cardholder data is never stored in application servers, logs, or databases outside the defined PCI DSS scope. Payment processing uses gateway tokenisation — the booking engine sends card details directly to the payment gateway (Stripe, Adyen, or Worldpay) using their JavaScript SDK, so card numbers never pass through Zenkins-built application servers. Network segmentation isolates the cardholder data environment from the hotel’s operational network, guest Wi-Fi, and PMS. We configure PCI DSS-eligible cloud services (AWS and Azure) with appropriate security group rules, encryption, and logging. For existing systems with PCI DSS scope reduction requirements, Zenkins conducts a scoping assessment and recommends architecture changes that minimise the number of systems in PCI DSS scope.

Yes. Zenkins provides managed IT services specifically designed for the operational demands of hotels and hospitality businesses — which differ significantly from standard business IT requirements. Hospitality operations run 24 hours a day, 365 days a year; check-in and check-out peaks, night audit processes, and overnight GDS and OTA reservation delivery all require IT systems to be continuously available. Our hospitality managed IT services include: 24/7 monitoring of PMS, booking engine, channel manager, and payment systems with hospitality-specific SLAs; help desk support covering both technical users (IT manager, night audit) and operational staff (front desk, housekeeping supervisors); network management including guest Wi-Fi, back-of-house operational network, and POS network segmentation; server management for on-premise PMS servers (many hotels still run OPERA on-premise); backup and disaster recovery with RTO targets aligned to hospitality operational impact; and cybersecurity monitoring covering payment systems and PMS access. India-based support teams provide cost-effective overnight and weekend coverage for hotel groups and hospitality technology companies.

Yes. Zenkins builds loyalty programme platforms for hotels, hotel chains, and travel companies from the ground up, and provides integration and modernisation services for organisations with legacy loyalty systems. A modern hotel loyalty platform includes: a points engine (earning rules based on stay value, F&B spend, ancillary purchases; redemption rules for room nights, upgrades, and experiences), tier management (status levels, qualification criteria, benefits administration), member portal and mobile app (points balance, booking history, reward catalogue, preference management), personalisation engine (next-best-offer models, upsell logic based on stay history and member tier), CRM integration (Salesforce, Braze, or custom CRM for member communications), and partner programme management (airline miles earn and burn, credit card partner integration). For hotel chains with large member databases and high transaction volumes, we architect loyalty platforms with the database and caching layer performance required to handle check-in and checkout points posting at scale.
