Tour Operator Booking Software Glossary

Introduction

This glossary defines the terms used most frequently in tour operator booking software, online distribution, and reservation management. Whether you are evaluating booking platforms for the first time, setting up an OTA distribution strategy, or trying to understand a software vendor's feature list, these definitions provide a consistent reference for the concepts behind the terminology.

Core Booking Concepts

Availability refers to the number of remaining seats, spaces, or participant slots for a specific tour product at a specific departure date and time. Real-time availability means the number displayed to customers reflects every confirmed booking from every channel at the moment of viewing, rather than a count that may be delayed or calculated based on channel-specific allocations.

Booking engine is the customer-facing system that allows travelers to browse tour availability, select dates and times, enter participant details, process payment, and receive a booking confirmation. The quality of the booking engine directly affects your direct booking conversion rate. See the booking engine and OTA connectivity guide for more detail.

Booking window is the period during which bookings can be made for a specific product. A product with a booking window of 90 days allows bookings to be made up to 90 days in advance. A minimum booking window of 24 hours prevents last-minute bookings closer than 24 hours to departure.

Cancellation policy is the set of terms that governs whether and how a customer can cancel a booking, and whether they receive a refund. Common structures include full refund if cancelled more than 48 hours before departure, 50% refund within 48 hours, and no refund within 24 hours.

Capacity is the maximum number of participants that can be accommodated on a specific tour or transport departure. Capacity may be set at the product level as a standard maximum, or it may be determined dynamically by the resources assigned to each departure.

Confirmation is the automated email or message sent to a customer immediately after a booking is completed, including booking reference number, departure details, payment confirmation, and any pre-trip information.

Departure is a specific instance of a tour or transport product at a specific date and time. A tour product may have multiple departures per day, per week, or per season. Each departure has its own capacity, its own resource assignments (guides, vehicles, equipment), and its own booking record.

Deposit is a partial payment collected at the time of booking, with the remainder due at a later date before the departure. Deposits are common for multi-day tours, private charters, and high-value bookings where the customer commitment needs to be secured well in advance.

Inventory is the total available supply of seats or spaces for a product across all departures and booking channels. In a unified inventory system, all booking channels draw from the same inventory pool. In an allocation-based system, each channel has a separate block of inventory allocated to it. Unified inventory is operationally superior because it prevents both overselling and underutilization.

Manifest is the list of confirmed participants for a specific departure, including names, contact information, any special requirements, and relevant operational notes. For transport operations, manifests include pickup and drop-off information for each passenger. Departure manifests are typically generated automatically from confirmed bookings in the booking system.

Overbooking occurs when more passengers are confirmed for a departure than its capacity allows. This typically happens when multiple booking channels are drawing from separate inventory pools and bookings from different channels arrive for the same departure simultaneously. A unified inventory system with real-time synchronization prevents overbooking.

Distribution and Channel Management

Allocation is a block of seats or inventory pre-assigned to a specific distribution channel or partner. Allocations require manual reconciliation if not all allocated inventory is booked, and they can lead to underutilization when one channel's allocation goes unused while another channel is turning away customers.

Channel manager is the component of a booking platform that connects your inventory to OTA platforms and keeps availability synchronized across all channels in real time. When a booking arrives through any channel, the channel manager updates available inventory everywhere else simultaneously. See the channel manager and OTA distribution guide for a full explanation.

Commission is the fee paid to a distribution partner (OTA, reseller, agent) for each booking they generate. Commission rates for major OTAs like Viator and GetYourGuide typically range from 20% to 30% of the booking value.

Direct booking is a booking made through your own channels without an intermediary: your website, your phone system, your Booking Desk, or Google Things to Do. Direct bookings carry no OTA commission, making them significantly more profitable per booking than OTA bookings at equivalent prices.

Distribution channel is any channel through which your tour or transport products can be booked. Channels include your own website, OTA platforms, reseller partners (travel agents, hotel concierge programs, visitor centers), Google Things to Do, and your own staff-facing booking tools.

Google Things to Do is Google's platform for displaying tour and activity products directly in Google Search and Google Maps results, with a direct booking link. Bookings through Google Things to Do carry no OTA commission. See the Google Things to Do operator guide for setup and optimization guidance.

OCTO (Open Connectivity for Tours, Activities and Experiences) is an open API standard for connectivity between booking platforms and OTA marketplaces. OCTO-compliant integrations provide standardized data exchange. Zaui is a founding member of the OCTO community.

OTA (Online Travel Agency) is a marketplace platform where travelers can discover and book tours, activities, and experiences. Major OTAs in the tour and activity space include Viator, GetYourGuide, Expedia, and Klook. OTAs charge operators a commission on each booking they facilitate, typically 20-30% of the booking value.

Reseller is a partner business that sells your tours or activities to their own customers, typically at a marked-up price, with the difference retained as their commission. Hotel concierges, travel agents, visitor centers, and wholesale tour operators are common reseller types in the tourism industry.

Zaui Connect is Zaui's supplier distribution network that allows Zaui-connected operators to share and receive availability with each other. A hotel can offer its guests booking access to a connected tour operator's live inventory. A shuttle operator can sell connections alongside a connected tour experience. See the channel manager guide for more on how Zaui Connect works.

Pricing and Revenue Management

Dynamic pricing is the practice of automatically adjusting prices based on conditions such as remaining availability, time until departure, day of week, and seasonal demand. Dynamic pricing is implemented through rules configured in the booking system, which apply adjustments automatically without manual intervention. See the dynamic pricing for tour operators guide for a full explanation.

Lead time is the time between when a booking is made and when the departure occurs. Lead time pricing adjusts the price based on how far in advance the booking is made.

Occupancy rate is the percentage of available capacity that is booked for a specific departure. A departure with 10 confirmed bookings on a 12-person capacity tour has an occupancy rate of approximately 83%.

Price floor is the minimum price that a product will be offered at, regardless of demand conditions or dynamic pricing rules. Setting a price floor prevents automated pricing from discounting below a level that covers costs or is acceptable for the operator's brand positioning.

Yield management is the practice of varying prices and availability across customer segments, booking timing, and demand patterns to maximize total revenue from a fixed capacity. Dynamic pricing is one component of yield management.

Operations and Resource Management

Booking Desk is a staff-facing interface in a booking platform that allows staff to take bookings by phone, at a front desk, or through concierge and retail partners without using the customer-facing booking checkout. Bookings taken through the Booking Desk draw from the same inventory as online and OTA bookings, preventing double-booking. See the Booking Desk guide for more detail.

Guide assignment is the process of linking a specific guide or instructor to a specific departure. In a booking system with resource scheduling, guide assignments are tracked and visible in departure manifests.

NERA AI is Zaui's operations intelligence layer that monitors booking data and proactively surfaces issues before they affect customers, including guide assignment gaps, product configuration problems, OTA integration errors, and pricing anomalies. See the NERA AI operations alerting guide for what it monitors and how it works.

Resource is any asset that is committed to a specific departure and that has limited availability: a guide, a vehicle, a vessel, a piece of equipment, a physical space. Resource scheduling in a booking platform tracks resource commitments across departures and prevents double-assignment.

Resource scheduling is the process of tracking which resources are committed to which departures and preventing those resources from being double-booked. See the resource scheduling for activity operators guide for a detailed explanation.

Technical Concepts

API (Application Programming Interface) is a standardized interface that allows two software systems to exchange data reliably. OTA integrations, payment gateway connections, and third-party service integrations all operate through APIs. The quality of an API integration determines the speed, reliability, and feature-completeness of the connection between systems.

Booking widget is the embedded booking interface that allows customers to search availability and complete bookings directly on your website, without being redirected to a third-party booking page.

Real-time sync is the immediate update of inventory across all connected channels when a booking is created, modified, or cancelled. Real-time sync means there is no delay between a booking being confirmed and available inventory being updated everywhere else.
