Frequently asked questions
- What is ADR (Average Daily Rate)?
- Average Daily Rate is the average price a vacation rental earns per occupied night, calculated as paid room revenue ÷ paid nights. It excludes cleaning fees and taxes and is the cleanest measure of nightly pricing power.
- What is RevPAR (Revenue Per Available Night)?
- RevPAR blends ADR and occupancy into a single number: total room revenue ÷ total available nights. It is the single best measure of how well a listing earns relative to its capacity.
- What is Occupancy Rate?
- Occupancy rate is the percentage of available nights that were paid. Healthy vacation rentals run 55–80%; under 45% usually signals pricing or visibility problems, over 85% usually signals underpricing.
- What is LOS (Length of Stay)?
- Length of Stay is the average number of nights guests book in a single reservation. A 1-night minimum maximizes bookings; a 3–5 night minimum maximizes margin by reducing turnover costs.
- What is PMS (Property Management System)?
- A Property Management System is the operational backbone of a vacation rental business — calendar, messaging, payments, cleaning, owner statements, and channel sync in one place. StayFlow is a modern, AI-native PMS.
- What is Channel Manager?
- A channel manager keeps a single source-of-truth calendar in sync across every booking site so the same night cannot be double-booked. Modern PMSes (StayFlow included) ship with channel management built in.
