Folio charges refer to the record of in-house charges made by a guest since their arrival at a hotel. A hotel folio is essentially an itemized list of charges and payments related to a guests stay at the hotel, including charges for room rates, taxes, meals, room service, laundry, phone calls, and any other services or amenities that were utilized during the stay. The use of folios is a common practice in the hotel industry, as it allows hotels to accurately track and manage their revenue and expenses. It also provides guests with a clear breakdown of their charges, which can help to avoid any confusion or disputes over billing. Folio charges can also refer to account maintenance fees charged to customers of a financial institution.
