The folio
One stay, one bill — or several windows on it when the company pays the room and the guest pays their own dinner.
The folio is where every rupee of a stay lands: the room nights the night audit posts, the dinner the restaurant charged to the room, the laundry, the minibar, the advance the guest paid three weeks ago, and the payment at the door. It is opened at booking and it is still there after the guest has gone.
Windows
A guest with a room, two restaurant bills and a spa treatment sometimes wants three invoices, or wants the company to pay the room while they pay their own dinner. The trade's answer is windows: several bills on one stay, each with its own payer and its own tax invoice, and a charge routed to the right one by rule.
A bill has a payer
Every folio says who will settle it — the guest, a company on account, an agent, or an OTA that already collected — and the invoice is made out accordingly. When the payer is an OTA, the invoice still names the guest who slept in the room: the OTA is who we collect from, not who the bill is for.
Moving money
- Split a payment across two tenders.
- Transfer a bill to a company's account — a settlement, not negative revenue.
- Post a discount, with a reason and a name on it; the discount ceiling is per role.
- Reopen a closed bill, with permission and a log entry, when the desk finds it was wrong.
- Money can go back: a refund is a posting with a method, not an edit.
What the folio refuses
It will not take a posting on a closed bill — an issued tax invoice must not change under the person holding it. The route for a wrong invoice is a credit or debit note, numbered, pointing at the original.
