A
Revenue

ADR

Average Daily Rate

The average room revenue earned for occupied rooms during a defined period. It is commonly calculated by dividing room revenue by the number of rooms sold.

Why it matters: ADR helps a hotel understand the average price achieved for sold rooms.
A
Technology

API

Application Programming Interface

A structured way for software systems to communicate with each other, exchange information or request defined actions.

Hotel example: An API can allow a hotel system to exchange rates, reservations or availability with another platform.
A
Operations

Availability

The quantity of rooms or accommodation units that are available for sale for a particular date, room type or rate configuration.

Why it matters: Accurate availability is fundamental to avoiding conflicting reservations across sales channels.
B
Direct Booking

Booking Engine

Software that allows a traveller to search available accommodation, review rates and complete a reservation through a hotel-controlled booking route.

Hotel example: A booking engine can connect the hotel website with live room availability and rates.
B
Reservations

Booking Reference

An identifier assigned to a reservation so the booking can be located, managed or referenced in communication between the guest, hotel and relevant systems.

C
Booking Terms

Cancellation Policy

The conditions that determine whether and when a reservation can be cancelled and whether charges or refunds may apply.

Important: Cancellation rules can vary by property, rate, booking source and specific reservation.
C
Distribution

Channel Manager

Hotel technology used to manage and distribute rates, availability and related booking information across supported sales channels.

Why it matters: A channel manager reduces the need to update each connected distribution channel separately.
C
Distribution

Channel Mapping

The process of matching room types, rate plans or other hotel inventory between a hotel system and an external distribution channel.

Why it matters: Incorrect mapping can cause rates or inventory to be sent to the wrong product.
C
Reservations

CRS

Central Reservation System

A central system used to manage reservation-related information, rates, availability or distribution across one or more properties or channels.

D
Direct Booking

Direct Booking

A reservation generated through a hotel’s own sales route rather than through a separate third-party accommodation marketplace.

HotelConnect24: HotelConnect24 applies 0% HotelConnect24 commission to the hotel’s own direct bookings.
D
Distribution

Distribution

The process of making hotel rooms or accommodation inventory available through different booking routes such as the hotel website, travel platforms, agencies or other supported channels.

D
Revenue

Dynamic Pricing

A pricing approach in which room rates may change according to factors such as demand, occupancy, timing, market conditions or other pricing rules.

G
Distribution

GDS

Global Distribution System

A distribution infrastructure traditionally used by travel agencies and other travel sellers to access travel inventory including accommodation.

I
Technology

Integration

A technical connection between two systems that allows defined information or actions to move between them.

Hotel example: A PMS integration may allow relevant reservation or availability information to move between systems.
I
Operations

Inventory

The rooms or accommodation units a property can make available for sale, usually organised by date, room type or other product structure.

M
Connectivity

Mapping

The process of linking equivalent rooms, rates or products between different systems so information reaches the correct destination.

M
Marketing

Metasearch

A hotel-search or comparison environment that can show accommodation options or rates from multiple booking sources and direct travellers toward a booking route.

N
Commercial

Net Rate

A rate supplied before a distributor or travel seller adds an applicable markup or margin under the relevant commercial arrangement.

Important: The exact meaning and permitted use depend on the relevant distribution agreement.
O
Revenue

Occupancy

A measure of how much available room capacity is occupied or sold during a particular period, often expressed as a percentage.

O
Distribution

OTA

Online Travel Agency

An online travel business or marketplace through which travellers can search and book accommodation and potentially other travel products.

Commercial note: OTA relationships can involve their own agreements, commissions or fees.
O
Operations

Overbooking

A situation in which confirmed reservations exceed the accommodation inventory that can actually be provided for the relevant date or room type.

Technology role: Connected availability can reduce risk, but no system can guarantee that every overbooking scenario is eliminated.
P
Operations

PMS

Property Management System

Software used by accommodation businesses to manage operational hotel functions such as reservations, guest stays, rooms and other property workflows.

Important: HotelConnect24 should not automatically be assumed to replace every hotel PMS.
P
Pricing

Rate Parity

A pricing concept concerning whether the same or comparable hotel rate is offered across different booking channels.

Important: Hotel pricing should be considered together with applicable commercial agreements and local rules.
R
Pricing

Rate Plan

A defined hotel pricing product that can combine a price with conditions such as cancellation terms, included services, meal plans or booking restrictions.

R
Revenue

Revenue Management

The practice of using demand, pricing, inventory and other information to make commercial decisions about how hotel rooms are sold.

R
Revenue

RevPAR

Revenue per Available Room

A hotel performance metric that relates room revenue to the total number of rooms available during a defined period.

Why it matters: RevPAR reflects both pricing and room utilisation rather than only the average sold-room rate.
R
Inventory

Room Type

A category used to group accommodation units with similar characteristics, for example Standard Double, Family Room or Suite.

S
Distribution

Stop Sell

An instruction or rule that prevents a room, rate or other accommodation product from being sold through a particular route for a defined period.

W
Technology

Webhook

A method by which one system can automatically notify another system when a defined event occurs.

Example: A webhook can be used to notify another approved system that a reservation-related event has occurred.
W
Distribution

Wholesaler

A business that can contract accommodation inventory for onward distribution to other travel sellers or booking channels under a defined commercial model.

X
Technology

XML

Extensible Markup Language

A structured data format that has historically been used in many travel and hospitality system integrations to exchange information.

Glossary FAQ

Questions About Hotel Technology Terminology.

Who is the Hotel Tech Glossary for?
The glossary is designed primarily for hotel owners, managers and commercial teams who want clear explanations of common hotel technology, distribution and revenue terminology.
What is the difference between a PMS and a channel manager?
A PMS generally focuses on property-management and operational workflows. A channel manager focuses on distributing rates, availability and related information across supported sales channels. The two systems can work together.
What is the difference between an OTA and a booking engine?
An OTA is an external online travel business or accommodation marketplace. A booking engine typically powers a hotel-controlled direct booking route, such as the reservation process linked from the hotel’s own website.
What is the difference between ADR and RevPAR?
ADR focuses on the average room rate achieved for sold rooms. RevPAR relates room revenue to all available rooms and therefore reflects both achieved pricing and room utilisation.
What is the difference between an API and a webhook?
An API provides a structured interface through which one system can request or exchange information. A webhook is commonly used to notify another system automatically when a defined event occurs.
Does HotelConnect24 replace a PMS?
HotelConnect24 should not automatically be assumed to replace every property-management system. The platform is designed around channel management, direct booking, distribution and supported connectivity with relevant hotel systems.
What does direct booking mean?
A direct booking is generally a reservation generated through the hotel’s own sales route instead of through a separate third-party accommodation marketplace. See Direct Bookings for more information.
What does rate parity mean?
Rate parity concerns whether the same or comparable hotel price is offered across different booking channels. The practical position can depend on commercial agreements, market strategy and applicable rules.
Can HotelConnect24 connect to external hotel systems?
HotelConnect24 is designed for supported connectivity with relevant hotel and partner technology where an integration has been implemented and configured. See Integrations.
Can I search the glossary?
Yes. Use the live search at the top of the A–Z section or choose a letter to filter the visible definitions.
Will more terms be added?
The glossary can be expanded as HotelConnect24 documentation and the resource library grow. New terms should be added when they are useful to understanding hotel operations, distribution or technology.
Glossary scope: Definitions are provided as general educational explanations for hoteliers. The exact meaning of a commercial, technical or contractual term can depend on the relevant system, provider, agreement or implementation. Where a specific contract or technical specification defines a term, that document governs the relevant relationship.

Hotel Technology Should Be Understandable.

Use the HotelConnect24 Hotel Tech Glossary whenever an acronym, distribution term or technical concept gets in the way of understanding how your hotel technology actually works.
