What we can do for you

Hotel groups, consolidators, and bed banks

Whether you want to increase your exposure to different client segments or broaden online distribution through different sales channels, we help consolidate and maintain your inventory. If you are an inventory supplier or run a hotel chain, we ensure integration into a wholesaler’s environment and help you manage inventory and bookings in real-time, be it a travel portal, mobile app or travel website.

Travel agencies & OTAs​

We can extend your inventory with multiple GDS/CRS systems (Galileo, Sabre, Amadeus, Sirena, Worldspan), travel services and suppliers, to give you the cheapest fares and the best deals, and grow a daily number of reservations. With our solutions, routine tasks, like email confirmations and reporting, and streamline business processes, from reservation to online payment, issue of tickets and check-in will become automatic and effortless to you.

Airlines

We help you provide the lowest possible ticket price to your customers, by unbundling value-added offerings from the base price and implementing ancillary and air merchandising services. Allocated seating, priority boarding, airport transfer, travel insurance, online check-in, business lounges, hotel booking, car rentals, etc. We also can update legacy systems and streamline a software migration project to ensure that your company is one step ahead of the competition.

Cruise & ferry companies

We offer full-cycle software development for ferries operators, building robust IBE, implementing reservation systems, and accomplishing integration with the selected suppliers’ APIs. Whatever business problem you are facing – reducing IT costs and risks, introducing new tools for revenue optimizations, raising your customer service, or getting an attractive user-centric website or mobile app – we will deliver a solution that addresses your particular needs.

Airline startup

Once you decide to enter the commercial aviation market, we will share with you the right insights, industry know-how and technical expertise, to help grab a market share from global and local leaders. We are offering our long-standing expertise in the full cycle airline online distribution platform and IBE development, including both solutions built from scratch and on top of our in-house product components.

Tour operators

To make sure that you provide your customers with world-class itineraries faster than your competitors, we build solutions with strong back-office functionalities, dynamic packaging logic and upsell and cross-sell tools, and ensure seamless integration with PSS systems. We aim to give you access to the widest choice of airlines’ tariffs, including those not provided by GDSs, while generating a minimum number of GDS transactions.

MSE & virtual interlining services

We augment several integrations for fare finder engines to offer the cheapest flight options to end-users and put in place data update mechanisms, to showcase real-time availability.
