One house, one ledger.

The day starts before the first arrival. Night staff hand over pending departures, VIP arrivals and unresolved folios, and the handover is recorded rather than passed on by memory. Breakfast opens at 07:00 while housekeeping begins the departure list; check-out peaks between 08:00 and 11:00, and rooms are released to the board as they are cleaned. Arrivals build from 14:00, with group coaches often arriving together. Outlets run their own service windows, banquets follow event sheets, and the desk keeps a 24-hour presence. The night audit begins after the last outlet closes, checks arrivals, departures, rate variance and outlet postings, then rolls the date. The pattern repeats seven days a week, including weekends and holidays.

The PMS is the handoff point between departments, and the record is shared rather than copied. The desk uses it for reservations, check-in, room moves, folios and cashiering. Each outlet posts through the POS to the same guest ledger, mapped to its own revenue centre. Housekeeping works from the room-status board and releases rooms as they are cleaned, so the desk can sell them. Finance draws on the same postings for city ledger, credit limits, commission calculation and ageing. Reporting reads from the same tables: rooms, F&B, banquets and taxes should reconcile to one journal. When a department keeps a parallel list, the difference appears at close, not at the counter.

Scale changes the shape of the day rather than its sequence. A 120-room house can run two desk positions and one outlet; a 400-room house needs deeper shift cover, more revenue centres and a group desk. Seasonality moves the arrival curve and outlet hours, and it changes how many staff are on the floor. Groups arrive in blocks: rooming lists, pre-made keys and batch check-in are prepared before the coach reaches the door. Long stays and corporate accounts add another pattern, because charges may route to a master folio while incidentals stay with the guest. Each of these is a routing decision inside the same system, not a separate one.

Configure the ledger before the outlets. Agree the revenue centres, tax treatment, folio routing and settlement rules, then load rate plans, room types and package structures. Next, map each outlet’s item groups to the correct revenue centre and test charge-to-room across a full arrival-to-departure cycle. Set the night audit checklist and the close calendar, including how month-end and 30-day close periods are handled. Boundary conditions deserve a written decision: what happens to an open folio after the date rolls, who may reopen a closed folio, how deposits and commissions are released, and which charges belong on a master account. Interfaces for locks, payment terminals and the channel manager should be scoped in the same exercise.
