How to Audit a Hotel Group Folio, Step by Step

What is a group folio, and what is on it?

A group folio is the hotel’s itemised bill for your block. Where the master account is the billing arrangement, the folio is the statement of what actually posted to it: each line typically has a date, a type of charge, a stay or confirmation number and an amount, and a summary or totals block at the end adds up each type of charge and shows a balance. Layouts differ between hotels: some print a confirmation number only on room charges, and some have no separate type column.

Large blocks produce long folios, which is the reason they are rarely checked closely. The checks below take them in an order that finds the cheapest problems first.

Why check the bill before you pay it?

Because the contract is on your side only until you pay. Most room block contracts give the group the right to review the final master account before settlement and set a window for raising disputes. Once the bill is paid, that review becomes a request for a refund instead of a correction.

What should you check first?

Work in this order.

1. Do the totals add up? Add the lines for each charge type and compare them with the summary at the end, then compare the summary with the printed balance. A bill that does not match its own lines is the simplest error to prove.
2. Is anything charged twice? Look for the same night, the same stay and the same amount appearing on two lines. A reversal and a re-post that cancel each other out are fine; a repeat with no reversal is not.
3. Does each room rate match the contract? Compare the rate billed per night with the rate in the contract for that room type and night. Blocks of mixed room types and peak and shoulder nights need the comparison done per night, not once for the block.
4. Do the fees match the contract? Check each fee against what the contract lists. A resort fee the contract waives should not appear. A fee the contract says is already included in the rate should not be added on top.
5. Did each charge go to the right account? A guest booked to pay their own way should not have room charges on the group’s bill, and a room set up as room-and-tax-only should not carry incidentals.
6. Do the nights match the bookings? Look for nights outside a guest’s booked dates, charges on a stay that was cancelled, and charges for a no-show your contract does not allow.
7. Does the attrition charge match pickup? If the hotel has billed attrition, compare it with your final pickup and the contract’s attrition terms before accepting it.

Which problems can you prove, and which do you have to ask about?

Split what you find into two piles, because they need different emails.

You can prove a problem when the bill and the contract alone settle it: a rate above the contracted rate, a waived fee that was charged, a line that appears twice, a total that does not match its lines. Quote the page and line, quote the contract term, and ask for a corrected folio.

You have to ask when the answer depends on facts the bill does not contain: whether a guest really checked out early, whether a fee is covered by a clause you read differently from the hotel, whether an attrition charge reflects the pickup the hotel counted. Frame those as questions and ask the hotel to show its figures.

Keep the two piles separate in what you send, and do not add them into one total. A dollar figure you can prove and a dollar figure you are asking about carry different weight, and mixing them makes the stronger claim easier to dismiss.

How do you raise a problem with the hotel?

Put it in writing to the group sales contact or the hotel’s accounting contact, and keep it short. For each item give the folio page and line, the amount, the contract term it conflicts with and what you want changed. Ask for a corrected folio, not a verbal adjustment, so there is a document to pay against. Check the dispute window in your contract before you start the clock on the conversation, and keep copies of what you send.

Can Blocks do this for you?

For part of it. Blocks’ invoice audit reads a hotel’s group folio and checks the sleeping-room charges against your contract and your bookings, then sorts findings into billing errors it can prove and charges to ask the hotel about. It reads group folios from different hotels and, where it is less sure it saw every row, asks the hotel instead of calling something an error. It does not check food and beverage, meeting-room or audio-visual charges, and it sends nothing to the hotel: you copy a summary into your own email. It is decision support, not legal or accounting advice.
