The minibar, linen, and what a clean costs
What the room was given, what the guest drank, linen out to the laundry and back, and the cost of one clean added up from what went in.
Two water bottles, one dental kit and three pieces of linen went into 304 at 09:50. That fact is worth more than the count at month end, because it is the count at month end, room by room, with a name on every line.
The minibar is sold from the room
A minibar is stock that lives in the room. It is filled from the store, what the guest drinks is a folio charge like every other rupee, and what is missing at check-out and not sold is variance with a name on it.
Linen goes out and comes back
Linen has a lifecycle, not a consumption. Issued to a room, it moves to soiled; a batch goes to the laundry with a count per kind; the laundry sends it back and the count is checked — received to fresh, rewash stays out, rejected and discarded written off with a reason.
What a clean costs
Consumables and chemicals at the price they were last bought; linen at a cost per wash — a sheet is not used up, it is laundered. Room by room, day by day, and the month's cost on the dashboard.
The housekeeping store is an outlet
The same store the kitchen uses, with its own location and its own ledger, so purchasing, receiving and the books treat it the same way.
