What Is a Guest Folio?
The running record behind every hotel bill — what it holds, the six folio types hotels actually use, a worked example with the arithmetic shown, and what happens to it at check-out.
A guest folio is the itemized, running record of every charge and payment on a guest's stay — room rate, tax and incidentals in, payments and adjustments out. It opens at check-in, updates in real time, and should reach zero at check-out unless the balance moves to a city ledger account.
A Folio at a Glance
The Six Folio Types Hotels Actually Use
Every folio on a property fits one of these, even when the PMS calls them something slightly different.
A Worked Folio Example
A 3-night stay at $120/night plus 10% tax, with a mid-stay deposit, a restaurant charge, and a final payment that brings the balance to zero.
Total charges across the stay: $441.00 ($360 room + $36 tax + $45 dining). Total payments: $441.00 ($150 deposit + $291 final payment). The deposit briefly puts the folio in credit — a negative balance, shown in brackets — which is normal and simply means the guest is ahead of their charges so far.
What Is the Difference Between a Folio and an Invoice?
A folio is a real-time, running record of charges and payments that can still change during the stay. An invoice is the final, formal billing document issued once the folio is settled at check-out, and it no longer changes afterward.
In practice, the folio is the working document the front desk and the guest both watch while the stay is in progress — a late room-service charge or a corrected tax line still belongs on the folio. The invoice is the snapshot taken the moment that folio closes: it is what an expense system, a travel manager or an accountant actually files, because by then nothing on it should move again.
What Is Folio Routing?
Folio routing is splitting one guest's charges between two or more payers — typically sending room and tax to a company or travel agent while personal incidentals, like the minibar or room service, stay on the guest's own card.
Group bookings are where routing shows up most often: a block of rooms for a conference or wedding runs on a master account for the shared costs — venue hire, catering, rooming-list rooms — alongside each attendee's own guest folio for anything personal they add during the stay. A PMS that can't route cleanly forces front desk staff to manually split a bill line by line at check-out, which is exactly the kind of error that produces a dispute later.
What Happens to the Folio at Check-Out?
The front desk reviews the folio, processes the final payment, updates the room's housekeeping status and sends a receipt. The folio's balance must reach zero through that final payment, unless it is instead transferred to a city ledger account for a company or travel agency to pay later.
That sequence — review folio, process final payment, update room status, send receipt, trigger housekeeping — is the standard check-out workflow most hotel PMS platforms, including Frontdesko, run through for every departure. Anything left unresolved at that point, such as a guest who leaves without settling (sometimes called a "skipper"), becomes a problem the night audit has to catch before the day closes.
Folio vs City Ledger
A folio belongs to one guest or group and is normally settled at check-out. A city ledger holds balances transferred off a folio for payers who are not settling at the desk — companies, travel agencies and past guests still owed collection — and is invoiced later, usually on a monthly cycle.
This is also how corporate billing works in practice: a company account posts room and folio charges to a running city ledger balance instead of the traveler paying at checkout, then receives one consolidated statement per billing cycle. See hotel direct billing and city ledger accounts for the full mechanics, including how Frontdesko's Direct Bill module handles it.
How Does the Night Audit Affect Folios?
The night audit reconciles every open folio against the day's payments, checks that no in-house folio has passed its authorised credit limit, and resolves any folio left unsettled by a no-show or early departure before rolling the business date forward.
Two of the night audit's standard outputs exist specifically because of folios: the trial balance, which confirms every folio's debits equal its credits across the property, and the high-balance report, which flags any in-house guest whose folio is approaching what their card will authorise. Catching that at 2am is a conversation with the guest; catching it at check-out on a long stay is a write-off. See the full night audit guide for how the rest of the overnight close works.

How does the night audit affect folios?
The night audit reconciles every open folio against the day's payments, checks that no in-house folio has passed its authorised credit limit, and resolves any folio left unsettled by a no-show or early departure before rolling the business date forward.
What is a master folio?
A master folio consolidates charges for a group or company across multiple rooms into one account, separate from each individual's own guest folio. A wedding block, for example, can have venue and catering charges on a master folio while each guest's personal minibar stays on their own.
Does a guest's folio balance have to be zero at check-out?
Yes, unless the remaining balance is deliberately transferred to a city ledger account for a company or travel agency to pay on a later cycle. Any other non-zero balance at check-out is an unsettled folio, which the night audit will flag.
