THE CONNECTIONS MATTER
Similar letters. Different jobs.
Connect the concepts behind the shorthand. Explore twelve distinctions for hotel, restaurant, event, and people teams.
ADR vs. OCC vs. RevPAR
ADR measures room revenue per sold room night. OCC measures the sold share of available rooms. RevPAR measures room revenue per available room night. On the same basis, RevPAR = ADR × occupancy expressed as a decimal.
RevPAR vs. TRevPAR vs. GOPPAR
RevPAR uses room revenue. TRevPAR uses total hotel revenue. GOPPAR uses gross operating profit. Strong room revenue does not by itself establish strong total revenue or profitability.
MPI vs. ARI vs. RGI
These indexes compare occupancy, ADR, and RevPAR respectively with a comparison group. An index of 100 means parity with that group. Confirm the same period, comparison set, and data basis.
PMS vs. CRS vs. RMS
A PMS handles property operations. A CRS manages central reservations and distribution. An RMS supports revenue decisions. Products can overlap; confirm which system owns each piece of data.
OOO vs. OOS
Both restrict room use, but they may affect available inventory and occupancy calculations differently. Check your PMS configuration and benchmark reporting rules before treating either status as an automatic denominator adjustment.
FIT: traveler or payroll tax?
Travel teams use FIT for an independent traveler. Payroll uses FIT for federal income tax. Spell out the meaning when sharing information between departments.
AP and MAP: read the context
AP may mean American plan or accounts payable. MAP may mean modified American plan or modified atmosphere packaging. Meal plans, finance reports, and food-safety documents use different meanings.
PIP: property or people?
An owner may mean a property improvement plan. HR may mean a performance improvement plan. These documents serve different purposes and should always be identified clearly.
BEO vs. ROS vs. RFP
An RFP requests a proposal. A BEO documents event service requirements. A run of show coordinates the timed execution. Keep approved versions aligned with the actual event contract.
TCS vs. RTE vs. HACCP
TCS describes a food-safety control need. RTE describes readiness for eating. HACCP is a hazard-control approach. A food can be both TCS and RTE; the labels answer different questions.
FOH vs. BOH
Front of house covers guest-facing service; back of house covers production and support. The handoff between them affects order accuracy, timing, and the guest experience.
SPLH vs. RevPASH
SPLH divides sales by labor hours. RevPASH divides restaurant revenue by available seat hours. One relates sales to staffing; the other relates revenue to seating capacity and time.
Less administration. More time for your people.
