Frequently asked
OneBook — your questions answered
What is travel reservation software?
Travel reservation software lets a travel business search live supplier inventory, price it, and take confirmed bookings — hotels, flights, transfers and more — from one system. OneBook is TraveleXe’s travel booking and reservation software: one booking flow for eight product types across 100+ pre-integrated suppliers, for both a B2B agent portal and a B2C storefront.
What is a booking engine for travel agents?
A booking engine for travel agents — also called a travel agent booking engine or travel agency booking engine — is the system an agent uses to search and book many suppliers at once at net rates, add a markup and issue vouchers. OneBook gives travel agents and agencies hotels, flights, transfers and packages in one booking engine, with agent credit control, markups, commissions and agent tiers.
Is there a hotel booking engine for travel agents that also books flights?
Yes. OneBook is a hotel booking engine for travel agents that also books flights, transfers, cars, cruises and sightseeing — eight travel product types in a single booking flow — so an agent never switches between a separate travel agent hotel booking engine and a flight system.
What is an Internet Booking Engine (IBE)?
An Internet Booking Engine is the software that lets a travel business search live supplier inventory, price it, and take a confirmed booking online. OneBook does this for eight product types — hotels, flights, transfers, cars, cruises, sightseeing, meals and guides — across both a B2B agent portal and a B2C storefront.
How many suppliers does OneBook connect to?
OneBook is pre-integrated with over 100 travel suppliers, including bedbanks, wholesalers, GDS and direct hotel contracts. It also draws on your own contracted inventory held in Invento, so owned and third-party stock are searchable in the same result set.
Can it run both B2B and B2C from one system?
Yes. The same engine powers an agent-facing portal with credit control, markups, commissions and agent tiers, and a public storefront for direct travellers. Both share one Order Center, so bookings from every channel are managed in one place.
Do we need developers to add a new supplier?
No. Supplier connections are configuration rather than code — you enable a supplier and supply your own credentials and contracted rates. Responses are normalised before they reach the booking flow, so a new supplier does not change your front end.
Can the booking engine be white-labelled for sub-agents?
Yes. Sub-agents and partners can be given branded storefronts running on the same engine, each with its own markups, credit limits and product access.
