Precise language, better decisions

The operator's glossary

24 terms defined the way an operator needs them — with the formula where one exists and the reason it should change what you do.

Showing 24 of 24 terms

A

ADR

Revenue

Room revenue divided by the number of nights actually sold, excluding cleaning fees and taxes.

ADR = Room revenue ÷ Booked nights

Why it matters: It isolates pricing power from demand. Read alone it flatters you; read with occupancy it explains RevPAR.

B

Booking window

Revenue

The number of days between when a reservation is made and when the stay begins.

Why it matters: Discount ladders and minimum stays should be anchored to your actual booking window, not last year's.

Break-even occupancy

Finance

The occupancy level at which contribution covers monthly fixed costs exactly.

Break-even occupancy = Break-even nights ÷ Sellable nights

Why it matters: The best single measure of how much downside risk a unit carries.

C

Cash-on-cash return

Finance

Pre-tax annual cash flow divided by the total cash put into the deal.

CoC = Annual cash flow ÷ Total cash invested

Why it matters: The comparison metric across deals, and the one most often inflated by omitting reserves.

Channel manager

Technology

The layer that keeps rates, availability and content consistent across booking platforms.

Why it matters: Double bookings and rate drift are almost always synchronisation failures, not human error.

Contribution margin

Finance

What each additional sold night contributes toward fixed costs and profit.

Contribution = ADR − Variable cost per night

Why it matters: It tells you the real floor rate below which selling a night destroys value.

F

First response time

Guest

The elapsed time between a guest message arriving and the first substantive reply.

Why it matters: The strongest single predictor of review outcome when something goes wrong.

L

LOS

Revenue

The number of nights in a reservation; also the restriction controlling minimum and maximum stays.

Why it matters: LOS controls protect against orphan nights and reduce turnover load — often worth more than rate changes.

N

NOI

Finance

Gross revenue less operating expenses, management and reserves, before debt service and tax.

NOI = Revenue − Operating expenses − Management − Reserve

Why it matters: The number that determines whether a unit is a business or a hobby.

O

Occupancy

Revenue

Booked nights divided by sellable nights, with owner and maintenance blocks removed from the denominator.

Occupancy = Booked nights ÷ (Total nights − Blocked nights)

Why it matters: A demand signal, not a goal. Very high occupancy usually means the rate is too low.

Orphan night

Revenue

A single night, or short gap, between two reservations that minimum-stay rules make impossible to sell.

Why it matters: Orphan nights are pure lost RevPAR and are usually fixable with a gap-aware minimum-stay rule.

P

Pacing

Revenue

The share of a future period already on the books at a given number of days out.

Why it matters: Pacing, compared to the same point last year, is the earliest reliable signal that pricing is wrong.

PMS

Technology

The system of record for reservations, calendars, guests and operational tasks.

Why it matters: Whatever the PMS cannot see, no downstream automation or AI can reason about.

Preventive maintenance

Operations

Maintenance performed on a schedule or condition trigger rather than in response to a breakdown.

Why it matters: Failures cost the repair plus refunds, blocked nights and a review that lasts a year.

Property knowledge base

Technology

The structured, verified record of access, amenities, quirks and local information for a property.

Why it matters: It is the grounding layer for every AI answer. Unverified facts are how automation loses trust.

R

Reactive share

Operations

The percentage of maintenance spend triggered by a failure rather than a schedule.

Why it matters: Above 60% you are funding emergencies, not running a maintenance program.

Review velocity

Guest

How quickly a listing accumulates reviews relative to its bookings.

Why it matters: Platforms weight recency; a strong historic rating with no recent reviews loses ranking.

RevPAR

Revenue

Revenue divided by every night the unit was available to sell, whether or not it sold.

RevPAR = ADR × Occupancy

Why it matters: The only headline metric that cannot be improved by raising rate alone. It is the portfolio scoreboard.

Rework rate

Operations

The percentage of turnovers that require additional cleaning or correction after being marked complete.

Why it matters: The cheapest cost lever in operations, and the one that improves reviews instead of damaging them.

S

Same-day turn

Operations

A turnover that must be completed between a morning checkout and a same-day check-in.

Why it matters: Compressed timing is where turnover failures cluster; capacity should be planned around these days.

Service recovery

Guest

The structured response to an in-stay problem: acknowledge, act, commit to a follow-up, close the loop.

Why it matters: Well-recovered stays frequently review better than uneventful ones.

SLA

Operations

A committed response and resolution time for a defined class of issue.

Why it matters: Without SLAs, urgency is decided by whoever shouts loudest rather than by guest impact.

T

TRevPAR

Revenue

All revenue — room, fees, upsells — divided by available nights.

TRevPAR = Total revenue ÷ Available nights

Why it matters: Shows whether ancillary revenue is a real contributor or a rounding error in your model.

Turnover

Operations

The full process of returning a unit to guest-ready standard between stays.

Why it matters: The highest-frequency process in the business and the origin of most quality failures.
