The language of hospitality.
Made simple.

AI & Automation

Agentic AI ↗

Agentic AI — Τεχνητή νοημοσύνη με πράκτορες

Agentic AI describes artificial intelligence systems that can organise steps and use available tools towards a goal. The term is used differently across products. By itself, it does not specify which actions are permitted, how much autonomy is available or when human approval is required.

AI & Automation

Agentic RAG

Agentic RAG lets an AI agent decide when and how to retrieve information while preparing an answer. It may involve more than one lookup. The term describes how context is gathered; it does not imply permission to modify reservations or carry out financial actions.

AI & Automation

AI Copilot

Βοηθός AI

An AI application that assists a user with suggestions, retrieval or drafts within their work. Action scope and human oversight vary by product.

Distribution & OTAs

Airbnb

A platform connecting guests with hosts for stays and other offered experiences or services. Accommodation types and conditions vary by listing.

Distribution & OTAs

Allotment ↗

Allotment — Διάθεση δωματίων σε συνεργάτη

An allotment is an agreed quantity of rooms, by type and period, made available to a partner for booking. The agreement determines how long that allocation remains available, how unused rooms return to general sale and what financial commitments apply.

Integrations & Technology

API Connection

Σύνδεση μέσω API

A connection in which applications exchange data or request actions through documented interfaces. It needs error handling and, where required, access controls.

Integrations & Technology

API — Application Programming Interface ↗

API — Διεπαφή προγραμματισμού εφαρμογών

An API is a set of rules and operations through which one piece of software interacts with another. It defines what can be requested, which inputs are required and what response is returned. In hospitality, an API can underpin a connection between a PMS, a sales channel or a specialist service.

Guest Experience & Communication

Automated Messaging

Αυτοματοποιημένα μηνύματα

Sending messages according to rules, such as a set time before arrival. Correct booking data and safeguards help prevent inappropriate instructions.

AI & Automation

Automation

Αυτοματισμός

Executing predefined steps when specified conditions are met. Automation can use simple rules and does not necessarily require AI.

Distribution & OTAs

Availability

Διαθεσιμότητα

Units that can be booked for particular dates, after inventory and selling restrictions are taken into account.

KPIs & Analytics

Average Booking Value

Μέση αξία κράτησης · ABV

The total value of a defined set of reservations divided by their count. Unlike ADR, it measures value per booking rather than per sold room-night.

KPIs & Analytics

Average Daily Rate (ADR) ↗

Μέση ημερήσια τιμή (ADR)

ADR measures average room revenue for each room night sold during a period. It describes the rate achieved by sales, rather than the advertised room price or the amount paid per guest.

KPIs & Analytics

Average Length of Stay (ALOS) ↗

Μέση διάρκεια διαμονής (ALOS)

ALOS is the average duration, in nights, of the stays in a defined sample. It describes how long visits last and requires a clear definition of one stay, especially when a reservation includes several rooms.

KPIs & Analytics

Average Rate Index ↗

Δείκτης σχετικής μέσης τιμής (ARI)

ARI compares a property’s ADR with the aggregate ADR of a defined comparison group. A value of 100 means the same achieved average room rate, using a common period and revenue basis.

Distribution & OTAs

Bed Bank

Bed bank — Χονδρέμπορος καταλυμάτων

An intermediary that supplies accommodation to other travel businesses, such as travel agencies and tour operators, under business-to-business agreements. The property provides rates and availability for distribution through that network. A bed bank does not necessarily pre-purchase a fixed block of rooms, and its customer is typically a travel business rather than the final guest.

Revenue Management

BAR — Best Available Rate ↗

BAR — Καλύτερη διαθέσιμη τιμή

BAR is the best available public rate for a particular room type and stay search, without requiring a special corporate agreement or membership of a qualifying group. It often provides a reference for other offers, but its conditions still need to be checked.

Revenue Management

Booking Curve

Καμπύλη κρατήσεων

A booking curve shows how the accumulated bookings, room nights or revenue for a fixed stay date or period develop as that date approaches. Compare the same measurement at equivalent days before arrival and state whether cancellations are deducted. Unlike one reservation’s booking window, it records successive views of demand and helps examine booking pace and forecasts.

Distribution & OTAs

Booking Engine ↗

Booking Engine — Μηχανή κρατήσεων

A booking engine lets a guest search for an available stay and proceed with a reservation through a property’s direct online booking path. It connects dates, guest numbers, available options and booking conditions with the process of submitting the reservation.

Distribution & OTAs

Booking Funnel

Διαδρομή ολοκλήρωσης κράτησης

The sequence from searching availability to booking confirmation. Tracking where visitors leave helps identify friction.

Revenue Management

Booking Pace

Ρυθμός κρατήσεων

How reservations accumulate as stay dates approach, often compared with the equivalent booking lead time in another period.

KPIs & Analytics

Booking Window ↗

Χρόνος κράτησης πριν από την άφιξη

Booking window, also called lead time, is the interval between a reservation being made and the arrival date. It is usually expressed in days and describes how far in advance guests book their stay.

Distribution & OTAs

Booking.com

An online travel platform where travelers find and compare accommodation and other travel services. Partner terms depend on the property’s agreement.

Distribution & OTAs

CTA — Call to Action

CTA — Προτροπή για ενέργεια

In marketing, CTA means Call to Action: a clear prompt, often a button or link such as “Check availability”, that leads to the next step. A click is not a completed reservation. In stay restrictions, the same acronym means Closed to Arrival, which prevents arrivals on a date; that is a separate concept.

KPIs & Analytics

Cancellation Rate

Ποσοστό ακυρώσεων

Cancelled reservations as a percentage of a defined booking cohort. Use the same date basis and cancellation definition when comparing periods.

Payments & Finance

Card Preauthorization

Προέγκριση κάρτας

A temporary hold on a card that may be captured, released or expire. It is not itself a completed collection. Its validity depends on the provider and network.

PMS & Operations

CRS — Central Reservation System ↗

CRS — Κεντρικό σύστημα κρατήσεων

A CRS centralises reservations, rates and availability for one property or a group of properties across different points of sale. It supports central reservation operations and exchanges information with other systems according to the integrations available.

Revenue Management

Channel Cost

Κόστος καναλιού

Channel cost covers expenses attributed to acquiring and processing bookings through a distribution channel, such as commissions, transaction fees and allocated marketing spending. Comparing channels requires the same reporting period and a consistent method for assigning shared expenses. It is broader than an OTA commission and is not necessarily zero for direct bookings; it also differs from the property’s total operating costs.

Distribution & OTAs

Channel Manager ↗

A channel manager connects a property’s availability and selling settings with the channels where its accommodation is offered. It exchanges supported information, such as reservations, rates and restrictions, so distribution does not depend on separately updating every booking platform by hand.

Distribution & OTAs

Mapping ↗

Mapping — Αντιστοίχιση

Mapping matches an item in one system with its corresponding item in another. In accommodation distribution, it establishes which managed unit or room type, and which selling option where applicable, corresponds to a particular listing or rate on a booking channel.

KPIs & Analytics

Channel Mix

Μείγμα καναλιών

The distribution of bookings, room-nights or revenue by source channel. State which measure is used; each describes a different mix.

Payments & Finance

Chargeback

Chargeback — Αμφισβήτηση συναλλαγής κάρτας

A chargeback concerns reversal of a card payment through the card issuer's dispute process. It differs from a refund initiated by the business. For an accommodation payment, booking records, terms and evidence of service may be relevant; the outcome depends on the process and evidence in the particular case.

PMS & Operations

Check-in

Άφιξη / Check-in

The process of welcoming a guest and recording their arrival, checking the reservation and providing necessary information or access.

PMS & Operations

Check-out

Αναχώρηση / Check-out

Completing a stay: confirming departure, reviewing outstanding charges and updating the room’s operational status.

Greece & Compliance

Climate Crisis Resilience Fee ↗

Τέλος Ανθεκτικότητας στην Κλιματική Κρίση · ΤΑΚΚ

The Climate Crisis Resilience Fee, commonly called TAKK, is a levy applying to specified accommodation categories in Greece. It is borne by the guest and replaced the former accommodation tax. It relates to the daily use of a room or apartment under the applicable AADE framework.

Reservations

Closed to Arrival

Κλειστό για αφίξεις · CTA

A restriction preventing a stay from starting on a particular date. It does not necessarily prevent an existing stay from including that night. In marketing, CTA instead means Call to Action, a different concept.

Reservations

Closed to Departure

Κλειστό για αναχωρήσεις · CTD

A restriction preventing a stay from ending on a particular date. It differs from closing all availability.

Distribution & OTAs

Conversion Rate

Ποσοστό μετατροπής

The percentage of visits or users completing a defined action, such as a booking. Always specify the action and denominator being measured.

KPIs & Analytics

Cost per Occupied Room ↗

Κόστος ανά κατειλημμένο δωμάτιο (CPOR)

CPOR measures average rooms-department operating cost per sold room night. The result is meaningful only when the report clearly defines the expenses included in its cost base.

Greece & Compliance

Credit Document

Πιστωτικό παραστατικό

A credit document records a discount, return or other relevant adjustment to a transaction. The appropriate type depends on the original document and circumstances. It is distinct from a card refund and does not necessarily arise merely because a reservation was cancelled; the correct treatment is checked with the accountant.

Distribution & OTAs

Direct Booking ↗

Απευθείας κράτηση

A direct booking is a reservation made with the property itself through its website, by phone, by email or in person. The booking is made through the accommodation business’s own route rather than through a third-party booking platform or travel agency.

Distribution & OTAs

Direct Booking Website

Ιστοσελίδα άμεσων κρατήσεων

A property website enabling guests to book with the property itself, usually through a booking engine.

Greece & Compliance

Document Data Transmission

Διαβίβαση παραστατικού

In myDATA, transmission means electronically submitting the required document data to AADE through the appropriate channel. It differs from issuing the document or emailing its PDF to the customer. The platform response indicates acceptance or an error; successful registration does not replace accounting review.

Revenue Management

Dynamic Pricing ↗

Δυναμική τιμολόγηση

Dynamic pricing means adjusting the rates offered for future bookings as demand, availability and other conditions change. An operator can make these adjustments manually or use specialist software, working within an agreed pricing strategy.

Greece & Compliance

Electronic invoicing

Ηλεκτρονική τιμολόγηση

Electronic invoicing is the electronic issuance and handling of invoices within the applicable framework. A PDF or email alone does not establish that the required process was followed.

Distribution & OTAs

Expedia

An online travel platform for accommodation and other travel services. Listing there is a distribution channel, not a guarantee of booking volume.

Revenue Management

Forecast

Πρόβλεψη ζήτησης

An estimate of future demand or performance based on available data and assumptions. It is an uncertain projection, not a guaranteed outcome.

Reservations

Gap Night

Κενή ενδιάμεση νύχτα

An available night between two reservations that may be difficult to sell because of stay-length rules or other restrictions.

AI & Automation

GEO — Generative Engine Optimization

GEO — Προβολή σε απαντήσεις μηχανών AI

GEO is an emerging term for practices intended to improve content visibility within generative AI answers. It does not guarantee a citation or link to a property. Google states that its AI search features require no special markup or new files; established principles of useful, accessible content and SEO remain relevant.

Distribution & OTAs

GDS — Global Distribution System

GDS — Παγκόσμιο σύστημα διανομής

A network through which travel professionals search and book travel services, including hotels. For a property, GDS distribution provides a route to travel agencies and managed business travel. It requires suitable connectivity and commercial arrangements; being listed on an OTA does not automatically mean the property is distributed through a GDS.

Greece & Compliance

AFM — Greek Tax Identification Number

ΑΦΜ — Αριθμός Φορολογικού Μητρώου

AFM is the unique nine-digit identification number in the Greek tax register. It is not a room, property or software account number. The number of properties does not necessarily equal the number of tax IDs.

KPIs & Analytics

Gross Operating Profit per Available Room ↗

Μικτό λειτουργικό κέρδος ανά διαθέσιμο δωμάτιο (GOPPAR)

GOPPAR expresses gross operating profit per available room night. It connects operating revenue, the associated operating expenses and room capacity, without being equivalent to final net profit.

KPIs & Analytics

Gross Revenue

Ακαθάριστα έσοδα

Revenue before the deductions defined by a report. Check the treatment of taxes, extras and cancellations before comparing amounts.

Payments & Finance

Folio — Guest Account ↗

Folio — Λογαριασμός διαμονής

A folio is the itemised financial account associated with a guest or stay. It brings together relevant charges and, depending on the system, recorded payments and adjustments. It helps explain how the total was formed before the corresponding final billing documents are issued.

Guest Experience & Communication

Guest Journey

Διαδρομή επισκέπτη

The stages of a guest’s experience, from discovery and booking through the stay and post-departure communication.

Guest Experience & Communication

Guest Messaging

Επικοινωνία με επισκέπτες

Messages exchanged before, during and after a stay for questions, instructions and requests. Available conversation history depends on the connected channels.

PMS & Operations

Guest Profile

Προφίλ επισκέπτη

An organized record of necessary guest details and, where permitted, preferences or past stays. Access and retention require clear rules.

PMS & Operations

Housekeeping

Οροφοκομία / Καθαριότητα

Cleaning and preparing rooms and shared spaces. A room’s cleaning status is distinct from its reservation status.

Integrations & Technology

iCal / iCalendar ↗

iCalendar is a standard for exchanging calendar information, including events and time periods. In hospitality, iCal usually refers to calendar links through which services exchange blocked dates. It connects calendars with a defined set of information, rather than describing every aspect of a booking integration.

Greece & Compliance

AADE — Independent Authority for Public Revenue

ΑΑΔΕ — Ανεξάρτητη Αρχή Δημοσίων Εσόδων

AADE is Greece's independent authority responsible for public revenue administration and the application of tax and customs legislation. Its digital services include myDATA and myAADE. A software connection to those services does not mean that AADE endorses the entire product.

Integrations & Technology

Integration

Σύνδεση συστημάτων

Cooperation between systems through agreed data exchanges and workflows. Each integration has a defined scope, direction and update timing.

Distribution & OTAs

Inventory

Απόθεμα δωματίων

The rooms or units a property manages. Total inventory is not always the same as the number currently available for sale.

Greece & Compliance

Invoice

Τιμολόγιο

An invoice documents a sale of goods or provision of services and includes the required issuer, customer and transaction information. It is distinct from a reservation or folio. Correct issuance requires the appropriate document type and accurate tax details.

Greece & Compliance

Invoicing provider activation

Ενεργοποίηση παρόχου τιμολόγησης

Activation means preparing the particular business to use an invoicing provider, including issuer details, the service agreement and required procedures. It is more than creating a PMS account.

AI & Automation

Large Language Model

Μεγάλο γλωσσικό μοντέλο · LLM

A machine-learning model that processes and generates language using learned patterns. Its fluent answers can still be incorrect.

Reservations

Lead Time ↗

Χρόνος πριν από την άφιξη

In reservations, the interval between the booking date and arrival. It is commonly used as a synonym for booking window.

KPIs & Analytics

Length of Stay

Διάρκεια διαμονής (LOS)

LOS is the number of nights in an individual stay, counted from arrival to departure: arriving on the 10th and leaving on the 13th means three nights. It does not count guests and differs from ALOS, an average across multiple stays, or minimum stay, a selling restriction.

Greece & Compliance

Licensed electronic invoicing provider

Αδειοδοτημένος πάροχος ηλεκτρονικής τιμολόγησης

In Greece, an electronic invoicing provider uses licensed software for the prescribed document authentication and transmission services. AADE publishes a register of licensed software.

KPIs & Analytics

Market Penetration Index ↗

Δείκτης σχετικής πληρότητας (MPI)

MPI compares a property’s occupancy with the aggregate occupancy of a defined comparison group. Its reference point is 100, which means matching the group’s occupancy rather than having a fully occupied property.

Reservations

Maximum Stay

Μέγιστη διάρκεια διαμονής

A restriction setting the longest permitted reservation for the dates or rate plan to which it applies.

Distribution & OTAs

Metasearch

Metasearch — Σύγκριση προσφορών διαμονής

A service that brings together offers from different providers so travellers can compare prices for a property and selected dates. A link may lead to the property’s own website or an OTA to complete the booking. Metasearch traffic is therefore not automatically direct booking traffic; the booking destination matters.

Revenue Management

Minimum Stay ↗

Minimum Stay — Ελάχιστη διαμονή · MinLOS

Minimum Stay is a restriction setting the fewest nights an eligible reservation must contain. It applies to particular dates and selling options according to the system and channel. It measures nights in the stay, rather than how far in advance a guest makes the reservation.

AI & Automation

MCP — Model Context Protocol ↗

Model Context Protocol, or MCP, is an open standard for connecting AI applications with external data sources and tools. It provides a common way to describe and access available capabilities. It is not a language model and does not itself define what a particular connection can do.

PMS & Operations

Multi-account

Διαχείριση πολλών λογαριασμών

The ability to connect and manage several separate accounts from one workspace, including multiple accounts on the same channel. Each account retains its identity and associated property connections. This differs from multi-property, which describes managing several properties, and does not mean that the external accounts have been merged into one.

PMS & Operations

Multi-property

Διαχείριση πολλών καταλυμάτων

Managing several properties from a shared workspace while keeping their units, reservations and performance distinguishable.

Greece & Compliance

Municipal Stay Fee

Τέλος διαμονής παρεπιδημούντων

The municipal stay fee is a levy benefiting municipalities that applies to the specified accommodation cases and is calculated on the relevant rental or accommodation value. It is distinct from TAKK and VAT. Application and calculation depend on current rules and the business's circumstances and should be checked with its accountant.

Greece & Compliance

myDATA — AADE electronic books ↗

myDATA — Ηλεκτρονικά βιβλία ΑΑΔΕ

myDATA is AADE's electronic books platform. It receives the required document data and related accounting information. For a hospitality business, it forms part of the tax reporting workflow for its transactions. Its name stands for my Digital Accounting and Tax Application.

Greece & Compliance

MARK — myDATA Registration Number

ΜΑΡΚ — Μοναδικός Αριθμός Καταχώρησης

MARK is the unique registration number assigned by myDATA to a successfully transmitted document. It identifies that document within the platform. It is not the receipt or invoice number assigned by the issuer, nor a reservation number. Its presence alone does not certify that the tax treatment is correct.

Integrations & Technology

Native Integration

Ενσωματωμένη σύνδεση

A label for an integration offered as part of a product. The label alone does not establish that no partner or intermediary systems are involved.

KPIs & Analytics

Net Revenue

Καθαρά έσοδα

Revenue after specified deductions, such as discounts or commissions. Always state which deductions are included; definitions vary between reports.

Reservations

No-show

Μη εμφάνιση επισκέπτη

When a guest does not arrive as scheduled without cancelling under the agreed conditions. Any charge depends on the booking policy.

Integrations & Technology

OAuth — Application Authorization

OAuth — Εξουσιοδότηση πρόσβασης εφαρμογών

OAuth is an authorization framework that lets an application obtain limited access to a service without receiving the user's password for that service. Granted permissions define the access scope. OAuth is not itself a user authentication system or a guarantee that every connected application is secure.

KPIs & Analytics

Occupancy Rate ↗

Πληρότητα

Room occupancy is the percentage of available room nights sold during a defined period. It measures how much room capacity was used, counting rooms for each night rather than the number of guests or reservations.

Distribution & OTAs

OTA — Online Travel Agency ↗

OTA — Online ταξιδιωτική πλατφόρμα

OTA stands for Online Travel Agency: an online platform where travellers research and book travel services. In accommodation, it brings together property options, displays prices and conditions, and lets the traveller reserve a stay through the platform’s booking process.

PMS & Operations

Out of Order

Εκτός λειτουργίας · OOO

A room status indicating that a room cannot accommodate guests for a specified period, for example during repairs. It is normally removed from available inventory for those dates. Record the reason and dates and check readiness before returning it to use. It differs from a room awaiting cleaning or a commercial stop-sell restriction.

Reservations

Overbooking ↗

Overbooking — Υπερκράτηση

Overbooking occurs when reservations for a night exceed the capacity the property or a particular room type can actually accommodate. A double booking is the familiar case in which one unique unit has been allocated to two reservations whose occupied nights overlap.

Payments & Finance

Payment Capture

Capture — Οριστικοποίηση χρέωσης

Capture is the step that submits an authorized payment for collection and subsequent settlement. It differs from authorization, which temporarily holds an amount. Capture may happen automatically or separately where supported, and does not mean the money has already reached the property's bank account.

Payments & Finance

Payment Gateway ↗

Payment Gateway — Πύλη πληρωμών

A payment gateway is the technology service that securely passes online payment information from the checkout journey to payment processing infrastructure and returns the relevant result. For an accommodation business, it can form part of the online payment journey associated with a reservation.

Payments & Finance

Payment Processor

Επεξεργαστής πληρωμών

A service handling transactions between payment participants. Authorization, settlement and payout are distinct stages.

Payments & Finance

Payment Settlement

Settlement — Διακανονισμός πληρωμής

Settlement is the stage when funds from a processed transaction move between the financial parties towards the merchant side. In some providers' terminology, funds becoming available in the account balance and the later bank payout are separate steps. An authorized transaction does not mean an immediate bank deposit.

Revenue Management

Pickup

Μεταβολή κρατήσεων / Pickup

The change in bookings or revenue on the books for the same stay dates between two observation points. Specify whether cancellations are deducted.

Integrations & Technology

PWA — Progressive Web App ↗

PWA — Προοδευτική διαδικτυακή εφαρμογή

A Progressive Web App, or PWA, is an application built with web technologies that can offer an experience similar to an installed application. It runs through a browser and can be installed on supported devices. The term describes an application approach, rather than a universal checklist of features.

PMS & Operations

PMS — Property Management System ↗

PMS — Σύστημα διαχείρισης καταλύματος

A property management system is the software used to organise an accommodation business around its reservations, rooms and guests. It connects who is staying, when they are staying and the work needed before arrival, during the visit and at departure.

Distribution & OTAs

Rate Parity

Ισοτιμία τιμών

Consistency of prices across channels for genuinely comparable booking conditions. It does not imply an identical contractual or legal obligation everywhere.

Revenue Management

Rate Plan ↗

Rate Plan — Τιμολογιακό πλάνο

A rate plan is an organised pricing option for selling a stay, such as a flexible or non-refundable rate. In everyday commercial use, it is associated with particular conditions and inclusions. Technical structures differ: those conditions may belong to the combination of room type and rate plan.

Payments & Finance

Refund

Επιστροφή χρημάτων

Returning a paid amount according to the policy and payment process. Cancelling a reservation does not always trigger an automatic refund.

Distribution & OTAs

Release Period

Περίοδος αποδέσμευσης

The agreed interval before arrival or the relevant stay date at which unused rooms in an allotment or block return to general sale. A seven-day release may return the unused balance seven days beforehand. The agreement defines the exact reference date and time; confirmed reservations are not automatically cancelled.

Reservations

Reservation

Κράτηση

An arrangement to use accommodation on specified dates, with guest details, a price and conditions. A confirmed reservation does not always mean payment is complete.

Greece & Compliance

Retail receipt

Απόδειξη λιανικής

A retail receipt documents a sale of goods or services to an individual consumer under the applicable framework. It differs from a simple payment confirmation. In accommodation, it is distinct from the special TAKK collection receipt; the appropriate document type depends on the transaction.

AI & Automation

RAG — Retrieval-Augmented Generation

RAG — Παραγωγή απαντήσεων με ανάκτηση πληροφοριών

RAG combines retrieval of relevant information with answer generation by a language model. An assistant might retrieve a cancellation policy from an approved handbook before responding. Quality depends on the sources and retrieval process; this approach does not guarantee a correct answer.

KPIs & Analytics

Revenue

Έσοδα

Sales value recognized for a period under a specified reporting basis. It is not the same as cash received or profit.

KPIs & Analytics

Revenue Generation Index ↗

Δείκτης σχετικού RevPAR (RGI)

RGI compares a property’s RevPAR with the aggregate RevPAR of a comparison group. It combines relative rate and occupancy performance, using 100 as its reference point.

Revenue Management

Revenue Management ↗

Διαχείριση εσόδων · RM

Revenue Management

Revenue Management System (RMS) ↗

Σύστημα διαχείρισης εσόδων (RMS)

An RMS is specialist software that supports pricing and inventory decisions. It analyses data and, depending on the product and configuration, recommends or applies rates and other commercial controls for a hospitality business.

KPIs & Analytics

Revenue per Available Room (RevPAR) ↗

Έσοδο ανά διαθέσιμο δωμάτιο (RevPAR)

RevPAR measures room revenue for each available room night in a period, including nights that remain unsold. It brings together the effect of occupancy and the average rate achieved on the room nights that sold.

KPIs & Analytics

Revenue per Occupied Room ↗

Έσοδο ανά κατειλημμένο δωμάτιο (RevPOR)

RevPOR measures revenue per sold, occupied room night, often including additional revenue associated with the stay. The report must identify the revenue categories included for the figure to be meaningful.

Guest Experience & Communication

Review Inbox

A workspace collecting reviews from supported sources so a team can read, organize and, where supported, respond to them.

Reservations

Room Block

Room block — Δέσμευση ομάδας δωματίων

A quantity of rooms held for specified dates and a purpose such as a wedding, conference or travelling group, before every individual reservation is completed. Track the overall allocation, reservations already taken from it and the remaining balance separately. Its effect on general availability depends on the block’s status and configuration.

PMS & Operations

Room Type

Τύπος δωματίου

A grouping of rooms with shared characteristics. A single room type may represent several physical rooms.

Reservations

Rooming List

Rooming list — Κατάλογος διαμονής ομάδας

A list of guests or individual reservations within a group, with arrival dates, departure dates and accommodation requirements. It helps turn an overall room block into specific reservations and prepare reception for arrivals. It may specify room types without assigning final room numbers; the latest changes must reach the team preparing the stay.

Distribution & OTAs

Stop Sell ↗

Stop Sell — Διακοπή πωλήσεων

Stop Sell is a setting that closes a selected accommodation offer to new reservations for a chosen period. Depending on the system, it can apply to a unit, room type, selling option or particular channel. Understanding its scope is essential to using it correctly.

Greece & Compliance

Tax entity

Φορολογική οντότητα

In property management, this term refers to the person or business whose tax details are used to issue documents. It does not necessarily correspond to one building, room or PMS account. Several properties may use one AFM or different AFMs, depending on the actual business structure.

KPIs & Analytics

Total Revenue per Available Room ↗

Συνολικό έσοδο ανά διαθέσιμο δωμάτιο (TRevPAR)

TRevPAR measures a property’s total operating revenue per available room night. It extends the view beyond accommodation revenue to include the other operating revenue that belongs to the business.

Integrations & Technology

Two-way Sync

Αμφίδρομος συγχρονισμός

Two-way sync means a connection transfers supported updates in both directions. For example, a channel may send reservations and receive availability. It does not mean every field can be changed on both sides or that updates are instantaneous; direction and precedence are defined for each type of information.

Guest Experience & Communication

Unified Inbox ↗

Unified Inbox — Ενιαία μηνύματα

A unified inbox brings guest conversations from supported channels into one management interface. Its purpose is to place the message alongside relevant guest or reservation context and let the operator reply through the available connection, reducing the need to switch repeatedly between separate applications.

PMS & Operations

Unit

Μονάδα καταλύματος

The smallest space managed as a separate accommodation unit, such as a room, apartment or villa. Its meaning depends on the property’s structure.

Greece & Compliance

VAT — Value Added Tax

ΦΠΑ — Φόρος Προστιθέμενης Αξίας

VAT is a tax applied to taxable supplies of goods and services under the relevant rules and exemptions. The appropriate treatment depends on the transaction and business. It is distinct from the Climate Crisis Resilience Fee; rates and their application should be checked with the accountant.

Distribution & OTAs

Vrbo

A vacation-rental platform focused on whole properties for private use. The platform sets the specific listing eligibility rules.

Reservations

Walk-in

Walk-in — Άφιξη χωρίς κράτηση

A guest who arrives at the property requesting accommodation without an existing reservation. Reception checks for an available, suitable room, agrees the rate and conditions, and records the reservation before completing check-in. A booking made online earlier that same day already exists and is not automatically a walk-in.

Integrations & Technology

Webhook

A notification one system sends to a registered address when an event occurs, such as a new booking. The receiver should validate it and handle repeated deliveries.

Revenue Management

Yield Management

Διαχείριση απόδοσης αποθέματος

Practices for setting prices and controlling access to limited inventory to improve revenue. The focus is how and to whom available capacity is sold.
