The folio
One guest, one stay, every charge and payment on it — and what its balance means.
The folio is the stay's account: every charge on one side, every payment on the other, and the balance between them.
What lands on it:
- Room and tax, posted nightly by the night audit for each night of the stay.
- Charges posted by the desk — laundry, minibar, a paid-out, a damage charge.
- Restaurant bills charged to the room from the POS.
- Payments, advances, and anything written off.
Reading it:
- A positive balance is money the guest owes. Negative is money held beyond what has been charged — usually an advance.
- Every line names who posted it and when. Nothing is edited after the fact; a wrong posting is voided with a reason, which leaves both lines visible.
- A folio may be split where a company pays part — the guest settles the rest. Set who pays what before departure, not during it.
At check-out the folio must reach zero, or go to the city ledger against a company that has credit. See Checking out.
