The language of hotel profit protection

Plain definitions of 68 terms behind hotel revenue, distribution, payments, finance, and ownership, and where each one connects to profit leakage. Written for owners, asset managers, and operators, not for search engines.

Core concepts

Hotel Profit Protection

The discipline of ensuring revenue a hotel has already earned actually reaches its bank account. Profit protection is distinct from revenue management: revenue management works to bring more money in, while profit protection makes sure what came in isn't lost to commission overbilling, uncollected virtual cards, chargebacks, or billing errors before it lands. Recovered dollars carry roughly 100% flow-through to GOP, because the cost of earning them has already been paid.

Profit Leakage

Revenue a hotel legitimately earned but never collected, or paid out in error. Leakage is structural rather than accidental: it happens because reservation data, payment data, and invoice data live in systems that were never built to reconcile against each other. Common surfaces include OTA commission overbilling, expired or unposted virtual cards, unrecovered chargebacks, uncharged no-show and cancellation fees, and lodging billing errors.

Flow-Through

The share of a revenue dollar that reaches gross operating profit after variable costs. A dollar of newly booked room revenue typically flows through at roughly 30–40%, because it carries commission, labor, amenity, and housekeeping cost. A recovered dollar flows through at close to 100%, because those costs were already incurred when the stay happened. This is why recovery has a disproportionate effect on GOP relative to acquisition.

OTA Commission Overbilling

Commission charged by an online travel agency on reservations where it was not owed, or charged at a rate above contracted terms. Typical causes include commission billed on cancelled or shortened stays, on no-shows, on fraudulent bookings, on the wrong rate basis, or at a percentage that does not match the negotiated agreement. Overbilling is recoverable through dispute, but only if each invoice line is reconciled against what actually occurred at the property.

OTA Reconciliation

Matching what an online travel agency billed or paid a hotel against what actually happened at the property and what the contract says. For each OTA reservation, the OTA invoice or payout line, the realized folio in the PMS and the contracted terms are compared. Lines that do not agree, such as commission on cancelled or no-show stays, the wrong rate basis, or a virtual card that was never charged, are disputed or collected inside the OTA’s window. See the complete guide to OTA reconciliation.

OTA Virtual Card (VCC)

A single-use prepaid card number issued by an online travel agency to pay a hotel for a prepaid reservation. Virtual cards leak when they are never charged, charged for the wrong amount, charged after the activation window closes, or expire before the front desk posts them. Because a virtual card sits outside the normal folio flow, an uncollected one produces no exception and no alert; the money is simply never collected.

Chargeback Representment

The process of contesting a disputed card transaction by submitting evidence that the charge was valid. In hospitality, representment requires assembling the folio, the reservation record, the cancellation policy the guest accepted, and proof of stay, within issuer deadlines. Hotels lose winnable chargebacks primarily because the evidence is scattered across systems and the deadline passes before it is assembled.

No-Show & Cancellation Fee Recovery

Charging the fees a hotel is contractually entitled to when a guest fails to arrive or cancels inside the penalty window. These fees are frequently left uncharged because posting them is a manual step at the front desk that competes with guest-facing work. Unlike most leakage, this is revenue the hotel is owed under terms the guest already accepted.

CLC Lodging Billing Errors

Discrepancies in billing for crew and project lodging booked through CLC and similar workforce lodging programs. Errors arise from rate mismatches, incorrect room-night counts, duplicate charges, and stays billed against the wrong authorization. Because these programs run on high volume at negotiated rates, small per-night errors compound quickly and are rarely caught by manual review.

Travel Agent Commission Leakage

Commission paid to travel agencies on bookings where it was not earned or was overstated, including commission on cancelled reservations, duplicate payments, and payments against rates that were never commissionable. Detecting it requires matching each commission claim to the reservation record and the applicable rate terms.

The Reconciliation Gap

The structural blind spot between what a hotel's PMS says happened, what the OTA extranet says happened, and what the bank says was paid. Each system is internally consistent and externally unverified. The gap is where profit leakage lives, and closing it requires matching records across all three rather than trusting any one of them.

GOPPAR

Gross Operating Profit Per Available Room. A profitability measure rather than a topline one, GOPPAR reflects what a hotel actually keeps after operating costs, which makes it the metric owners and asset managers manage against. Because recovered dollars carry near-100% flow-through, recovery moves GOPPAR far more efficiently than an equivalent amount of new revenue.

Profit Audit

A retrospective reconciliation of a hotel's own historical data across every leak surface, producing a specific dollar figure for revenue earned but not collected. An audit is diagnostic rather than predictive: it reports what already happened, using the property's own records, and requires no change to operations to perform.

KPIs & Performance

ADR (Average Daily Rate)

ADR (average daily rate) is rooms revenue divided by the number of rooms sold in a period, showing the average price paid per occupied room night. It excludes complimentary and out-of-order rooms in most reporting conventions. ADR measures pricing, not profit: a booking sold at a high rate through a costly channel can contribute less than a lower-rate direct booking.

CPOR (Cost per Occupied Room)

CPOR (cost per occupied room) is the operating cost of servicing each sold room night, usually rooms department expenses divided by occupied rooms. It covers items such as housekeeping labor, linen, guest supplies, and front desk costs. Tracking CPOR alongside ADR shows how much of each room sale remains after the cost of delivering it.

GOP (Gross Operating Profit)

GOP (gross operating profit) is a hotel's total operating revenue minus departmental expenses and undistributed operating expenses, before management fees and fixed charges such as property taxes, insurance, and rent. It is the standard measure of how well a property is being run operationally. Because recovered revenue carries almost no added operating cost, it tends to reach GOP nearly dollar for dollar; see flow-through and GOP and flow-through explained.

Hotel EBITDA

Hotel EBITDA is a property's earnings before interest, taxes, depreciation, and amortization, used to compare operating performance independent of how the asset is financed or depreciated. In hotel reporting it is closely related to NOI, and definitions vary by owner, lender, and reporting standard, so confirm the definition your agreements use. Revenue recovered from billing and collection errors has little associated cost, so it adds almost directly to EBITDA.

NOI (Net Operating Income)

NOI (net operating income) is the income a hotel produces after all operating expenses, management fees, and fixed charges, and it is typically reported before debt service, depreciation, and income taxes. Many owners and lenders also deduct a reserve for replacing furniture, fixtures, and equipment (FF&E) when reporting NOI. NOI drives valuation and loan covenants, so dollars lost to billing errors and uncollected charges affect asset value, not just the monthly P&L.

Occupancy

Occupancy is the percentage of available rooms that were sold in a given period, calculated as rooms sold divided by rooms available. It is one of the two inputs to RevPAR, alongside ADR. High occupancy can mask leakage, because every extra occupied room also creates another folio, commission, and payment that has to be reconciled correctly.

RevPAR

RevPAR (revenue per available room) is a hotel's rooms revenue divided by the number of rooms available for sale in a period. It can also be calculated as ADR multiplied by occupancy: for example (illustrative numbers only), a $150 ADR at 70% occupancy gives a RevPAR of $105. RevPAR is the most common top-line comparison between hotels, but it says nothing about what it cost to earn that revenue or whether it was actually collected.

RevPAR Index (RGI)

RevPAR Index, also called RGI (revenue generation index), compares a hotel's RevPAR to the average RevPAR of its competitive set, expressed so that 100 means fair share. For example (illustrative numbers only), a hotel at $110 RevPAR against a comp set at $100 has an index of 110. It shows how well a hotel captures demand relative to competitors, but it does not measure profit or collections.

TRevPAR

TRevPAR (total revenue per available room) is a hotel's total operating revenue from all departments, including rooms, food and beverage, parking, and other income, divided by rooms available. It gives a fuller view of revenue productivity than RevPAR, which counts rooms revenue only. Like RevPAR, it measures revenue earned, not revenue collected.

Distribution & OTAs

Agency Model

The agency model is an OTA arrangement in which the guest pays the hotel directly, usually at checkout, and the hotel later pays the OTA a commission on the stay. The OTA typically bills commissions on a periodic invoice. If that invoice is not matched against what actually happened (cancellations, no-shows, shortened stays), the hotel can pay commission on revenue it never earned; see OTA commission overbilling.

Billback

A billback is a charge that a hotel bills after the stay to a company, agency, or intermediary that is responsible for paying it, rather than collecting it from the guest at checkout. Billbacks are common for crew lodging, government stays, groups, and corporate direct-bill accounts. Each billback has to match what the contract actually pays for, or it will be short-paid, rejected, or left uncollected in the city ledger.

Booking Engine

A booking engine is the reservation tool on a hotel's own website that lets guests check availability, choose a rate, and book directly. Direct bookings through the booking engine usually avoid OTA commissions, though they still carry payment processing costs. Because the hotel collects payment itself, direct bookings shift the work of deposits, card authorization, and cancellation fees onto the property.

Channel Manager

A channel manager is software that sends a hotel's rates and availability to multiple distribution channels, such as OTAs and the GDS, and delivers reservations back into the property management system. It reduces overbooking and manual rate loading across channels. A channel manager moves reservations; it does not audit commission invoices, virtual card payments, or later changes to a stay.

Commission

A commission is a fee a hotel pays to a third party, such as an OTA or travel agent, calculated as a percentage of the revenue from a booking it produced. The rate and the revenue it applies to are set by contract. Commission leakage occurs when a hotel pays on the wrong amount, at the wrong rate, or on a stay that was cancelled, no-showed, or shortened; see OTA commission overbilling.

GDS (Global Distribution System)

A GDS (global distribution system) is a network that travel agents and corporate travel tools use to search and book airline seats, hotel rooms, and rental cars, such as Amadeus, Sabre, and Travelport. Hotel bookings made through a GDS often carry a travel agent commission. Those commissions need to be tracked through to payment so the hotel neither overpays nor pays on stays that did not happen; see travel agent commissions.

Merchant Model

The merchant model is an OTA arrangement in which the OTA collects payment from the guest and later pays the hotel a net rate, keeping the difference as its margin. Payment to the hotel is often made with a single-use virtual card that the hotel must charge within a set window. Virtual cards that are never charged, or charged for less than the full amount, are a frequent source of lost revenue; see OTA virtual card not charged.

OTA (Online Travel Agency)

An OTA (online travel agency) is a third-party website or app that sells hotel rooms to travelers, such as Booking.com or Expedia, in exchange for a commission or margin on each booking. OTAs work under either a merchant model or an agency model, and many hotels use both. OTA bookings are a common source of leakage when commissions are billed on stays that were cancelled, no-showed, or shortened; see the true cost of OTA bookings.

Rate Parity

Rate parity is the practice of offering the same room rate for the same room and conditions across all distribution channels, including the hotel's own website and OTAs. Some distribution contracts have included parity requirements, and their enforceability differs by country, so confirm the terms of your own agreements. Parity is a pricing question; it does not ensure that the commission billed on each booking matches the contract.

Payments & Chargebacks

Authorization

An authorization is a card issuer's approval of a transaction for a specified amount, confirming the card is valid and the funds or credit are available at that moment. An authorization reserves the funds but does not move money; the hotel is paid only after the transaction is settled. Authorizations that are allowed to lapse before settlement are a common reason charges fail or are disputed.

Card-Not-Present (CNP) Transaction

A card-not-present (CNP) transaction is a card payment where the physical card is not presented to the merchant, such as a booking taken online, by phone, or by email. Hotels process many CNP charges for deposits, prepaid stays, and no-show fees. CNP transactions generally carry more chargeback risk than card-present payments, so documenting the guest's agreement to the terms matters.

Chargeback Reason Code

A chargeback reason code is the code a card network assigns to a dispute to identify why the cardholder or issuer is reversing a charge, such as fraud, services not received, or cancelled reservation. The reason code determines what evidence the hotel needs and how long it has to respond. Matching the response to the reason code is central to chargeback representment; see winning more chargebacks.

Friendly Fraud

Friendly fraud is when a cardholder disputes a legitimate charge they authorized, such as a completed stay or a valid no-show fee, and asks their bank to reverse it. It can be intentional or the result of a guest not recognizing the charge. Hotels can often win these disputes with a timely, well-documented response; see OTA fraudulent bookings and hotel payment fraud.

Incremental Authorization

An incremental authorization is an additional authorization added to an existing card hold when a guest's charges grow beyond the original amount, such as an extended stay or large incidental charges. It keeps the total authorized amount in line with the folio. Card network rules govern when incremental authorizations are allowed, so confirm the details with your payment processor.

Interchange

Interchange is the fee a merchant's bank (the acquirer) pays to the cardholder's bank (the issuer) on each card transaction, set by the card networks and passed on to the merchant as part of its processing costs. Rates vary by card type, transaction type, and how the transaction was processed. Card-not-present and poorly documented transactions can qualify for higher rates, so processing practices affect cost.

PCI DSS

PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements for any business that stores, processes, or transmits payment card data, maintained by the PCI Security Standards Council. It covers areas such as network security, access control, encryption, and monitoring. Hotels should confirm their specific compliance obligations with their payment processor and a qualified assessor.

Pre-Authorization

A pre-authorization is a temporary hold placed on a guest's card at booking or check-in to cover the expected room charges and incidentals. It is later adjusted and settled for the final amount at checkout. Holds that are too small, or that expire before the stay ends, can leave the hotel unable to collect the full folio.

Retrieval Request

A retrieval request is a request from a card issuer, sent through the merchant's processor, for a copy of the transaction record or supporting documents before or instead of filing a chargeback. It typically arises when a cardholder does not recognize a charge. A prompt, complete response, such as the signed registration card and folio, can resolve the question before it becomes a dispute.

Settlement

Settlement is the process of submitting authorized card transactions, usually in a daily batch, so the funds move from the card issuer to the merchant's bank account. Until a transaction settles, the hotel has not been paid. Charges that are authorized but never settled, or settled for the wrong amount, create revenue that shows on the folio but never reaches the bank.

Receivables & Finance

Accrual

An accrual is an accounting entry that records revenue when it is earned or an expense when it is incurred, even if cash has not yet changed hands. Hotels commonly accrue OTA commissions owed and direct-bill revenue not yet collected. Accruals that are never trued up against actual invoices and payments can hide both overpayments and uncollected revenue; confirm treatment with your accountant.

AR Aging

AR aging is a report that groups a hotel's unpaid receivables by how long they have been outstanding, typically in 30-day buckets (current, 31 to 60, 61 to 90, and over 90 days). It shows which accounts need follow-up and how collectible the ledger is. The older a balance gets, the less likely it is to be collected in full.

City Ledger

The city ledger is a hotel's accounts receivable for amounts owed by parties who are not currently in-house, such as direct-bill companies, groups, crew and government accounts, and departed guests with balances. Charges move from the guest ledger to the city ledger at checkout when they are billed rather than paid. Aging city ledger balances are one of the clearest signs of uncollected revenue; see hotel accounts receivable and direct bill.

Direct Bill

Direct bill is an arrangement in which a hotel extends credit to an approved company or organization and invoices it after the stay instead of collecting payment from the guest. It is common for corporate accounts, groups, and crew lodging. Direct-bill balances need credit approval, accurate invoices, and follow-up, or they age into write-offs; see hotel accounts receivable and direct bill.

Folio

A folio is the itemized record of a guest's or account's charges and payments for a stay, including room, tax, incidentals, and any adjustments. The final folio is the basis for the guest's bill and for any direct-bill invoice. An accurate, complete folio is also key evidence when a charge is disputed.

Guest Ledger

The guest ledger is the set of open accounts for guests currently staying at the hotel, holding room, tax, and incidental charges until checkout. It is sometimes called the front office or in-house ledger. At checkout each balance is either paid or transferred to the city ledger for billing.

Month-End Close

Month-end close is the accounting process of reconciling accounts, recording accruals and adjustments, and finalizing a hotel's financial statements for the month. It typically covers bank and credit card reconciliations, ledger reviews, and payables and receivables. Items that are not reconciled at close, such as unmatched OTA payments, tend to be carried forward and forgotten; see the hotel month-end close process.

Night Audit

The night audit is the daily process, usually run overnight, of posting room and tax charges, balancing the day's transactions, and closing the business date in the property management system. It confirms that the day's activity is recorded and internally consistent. It does not verify that OTA commissions, virtual cards, or direct-bill invoices were later paid correctly; see what the night audit misses.

Reconciliation

Reconciliation is the process of comparing two sets of records, such as the property management system and the bank, or an OTA invoice and the actual stays, to confirm they agree and to explain any differences. It is how hotels catch errors in commissions, payments, and billbacks. When reconciliation is skipped or done only in summary, differences go unexplained; see the reconciliation gap.

Write-Off

A write-off is the removal of a receivable from the books after the hotel decides it cannot be collected, recorded as bad debt or an adjustment. Write-offs reduce revenue or increase expense in the period recorded. Many write-offs trace back to fixable causes, such as expired virtual cards, missed billing deadlines, or disputes that were never answered.

Groups & Contracts

Attrition

Attrition is the difference between the number of room nights a group contracted for and the number it actually used. Group contracts often include an attrition clause that allows a set shortfall and requires the group to pay for room nights below that threshold. Attrition charges that are allowed in the contract but never calculated or billed are lost revenue.

Cut-Off Date

The cut-off date is the date after which a hotel may release unreserved rooms in a group's room block back to general inventory. Reservations made after cut-off are usually accepted only if space is available, and possibly at a different rate. The cut-off date is also the point at which pickup is measured for attrition.

Guaranteed Reservation

A guaranteed reservation is a booking secured with a payment method, deposit, or company guarantee, so the hotel holds the room and can charge for it if the guest does not arrive. The guarantee terms, such as a one-night charge for a no-show, are set by the hotel's policy and disclosed at booking. Guaranteed reservations are only valuable if the hotel actually charges the fees they allow.

Late Cancellation

A late cancellation is a reservation cancelled after the deadline in the hotel's cancellation policy, which may allow the hotel to charge a penalty, often one night's room and tax. The policy must be clearly disclosed at booking for the fee to hold up if disputed. Late cancellations that are not charged, or charged without documentation, often end up as lost revenue or lost chargebacks.

No-Show

A no-show is a guest with a reservation who neither arrives nor cancels within the hotel's cancellation window. Under a guaranteed reservation, the hotel may charge a no-show fee according to its disclosed policy. No-show fees that are eligible but never charged, and commissions paid on no-show bookings, are two common leaks; see no-show and cancellation fees.

Room Block

A room block is a set number of rooms a hotel holds for a group, event, or account over specific dates, usually under a group contract. Rooms in the block are reserved for that group until the cut-off date. Block terms determine what the hotel can bill if the group does not fill its rooms.

Rooming List

A rooming list is the list of guest names, arrival and departure dates, and room types that a group or account sends the hotel to assign rooms within a block. For crew and contract lodging it is also the record of who was authorized to stay. Comparing the rooming list to what was billed helps catch stays that were missed, duplicated, or billed to the wrong party.

Crew & Government Lodging

Crew Lodging

Crew lodging is hotel accommodation provided under contract for transportation crews, such as railroad, airline, and trucking workers, usually on short-notice, rotating stays billed to the employer or a lodging program rather than paid by the guest. Some crew lodging is managed through third-party programs such as CLC® (now Corpay Lodging). Because billing depends on each program's rules, crew stays are prone to short-pays and rejected charges; see running a crew hotel and the crew lodging billing errors checklist.

Extended Stay

An extended stay is a hotel stay of several consecutive nights or longer, typically a week or more, and also describes hotels designed for such stays, with kitchens and weekly rates. Long stays reduce turnover costs but concentrate large balances on single folios or accounts. In many jurisdictions, stays beyond a set number of consecutive nights change how lodging taxes apply, so confirm the local rules.

Per Diem

A per diem is a fixed daily allowance an employer or government agency pays for a traveler's lodging, meals, and incidental expenses. In the United States, the General Services Administration (GSA) publishes per diem rates for federal travel within the continental US, and many other organizations use them as a benchmark. Hotels selling to government or per-diem travelers should confirm the current rate for their location and what the traveler's agency will actually reimburse.

Tax-Exempt Stay

A tax-exempt stay is a hotel stay on which some or all lodging taxes are not charged because the guest or paying organization qualifies for an exemption, such as certain government travelers. Exemption rules vary by state and locality, and hotels usually must collect specific documentation to support them. Missing or invalid exemption paperwork can leave the hotel liable for the tax, so confirm requirements with your tax advisor; see government and emergency lodging.

Workforce Lodging

Workforce lodging is hotel accommodation for groups of workers on projects away from home, such as construction, utility, energy, or disaster-recovery crews, often booked in blocks and billed to the employer. Stays can run from a few nights to many months. Clear direct-bill terms and regular invoice reconciliation matter because a single account can carry a large balance; see workforce and construction crew lodging.

Ownership & Management

Asset Manager

A hotel asset manager is the owner's representative who oversees a hotel's financial performance and value, working with the management company rather than running daily operations. Asset managers review budgets, capital plans, operator performance, and returns against the investment plan. Revenue leakage matters to them because it reduces NOI and, with it, asset value; see hotel asset management KPIs.

FDD (Franchise Disclosure Document)

An FDD (franchise disclosure document) is the legal disclosure document a franchisor must give prospective franchisees in the United States before a franchise is sold, under the Federal Trade Commission's Franchise Rule. It is organized into 23 required items covering areas such as fees, initial investment, franchisee obligations, and financial statements. Prospective hotel franchisees should review it with an attorney; see hotel franchise fees explained.

Franchise Agreement

A franchise agreement is the contract that grants a hotel owner the right to operate under a brand's name and systems in exchange for fees and compliance with brand standards. Fees commonly include royalties and program or marketing fees, often calculated on rooms revenue, plus reservation and technology charges. Because many fees are revenue-based, the terms are worth reviewing carefully; see hotel franchise fees explained.

Management Agreement

A management agreement is the contract under which a hotel owner hires a management company to operate the property on the owner's behalf. It commonly sets a base fee tied to revenue and an incentive fee tied to profit, along with the term, performance tests, reporting duties, and termination rights. Owners should confirm how the agreement assigns responsibility for revenue audit and collections; see how to evaluate a hotel management company.

PIP (Property Improvement Plan)

A PIP (property improvement plan) is a list of renovations and upgrades a brand requires a hotel to complete to meet current standards, often triggered by a sale, a change of franchise, or a franchise renewal. PIP costs can be significant and usually come with deadlines. Buyers typically price the PIP into an acquisition; see the hotel acquisition due diligence checklist.
