Hotel-tech vocabulary, in plain words. Deeper guides are being written module by module.
ADRAverage Daily Rate — room revenue divided by rooms sold. The price you actually achieved.
RevPARRevenue per available room — room revenue divided by ALL rooms. Occupancy and price in one number.
ARIAvailability, Rates, Inventory — the trio every channel needs to stay current. HubPMS pushes it in ~2s.
Channel managerThe machinery that keeps OTAs in sync so you never sell the same room twice.
OverbookingTwo guests, one room. In HubPMS it is blocked by a database constraint, not by hope.
Rate parityThe same price everywhere. The Parity Watchdog catches whoever breaks it with your inventory.
Derived rateA rate defined as 'parent −10%'. Change the parent once; everything follows.
Stop-sellA hard 'do not sell' switch for a date — pushed to every channel at once.
No-showA guest who never arrived. Mark it once; policies and OTA reporting follow.
FolioThe guest's running bill: room, taxes, extras, payments — every line traceable.
City taxPer-person-per-night municipal tax, often age-exempt and capped — model it once as a rule.
ChargebackA card payment pulled back. Dispute Shield builds the evidence pack in one click.
