Hotel master bill audit
Audit your hotel master bill before you pay it.
The final master bill is the hotel's version of your event. A master bill audit checks it against what you actually agreed: the contract, every revised BEO, the addenda and the concessions you negotiated.
The short answer
A hotel master bill audit compares each charge on the final master account with the term that governs it. That means the contracted room rate, the F&B minimum, the service charge percentage, the comp room ratio, the approved BEO headcount and any later change orders. Anything that doesn't match, or that has no supporting term, gets flagged for review.
FolioMatch does this for planners. You upload the contract, BEOs, addenda and final bill. FolioMatch lists the charges that need attention, shows its calculation, and cites the source page for both the agreed term and the billed line.
Why the master bill deserves an audit
A group master bill for a three-day conference can run to dozens of pages. It combines room and tax, banquet checks, room rental, AV, service charges, staffing, parking and adjustments, and it's often posted by several hotel departments. The hotel's accounting team builds it from its own systems. It is not a line-by-line copy of your contract.
Most differences aren't bad faith. A rate gets keyed from the rack table instead of the group table. A revised BEO never reaches banquet accounting. A comp room is credited at the wrong ratio. A Wi-Fi waiver agreed in an addendum doesn't make it into the billing instructions. Each one is small next to the total, and each one is easy to miss when you're reviewing 60 pages under a payment deadline.
An audit is how you find those differences while the hotel still has the documents and people who can fix them. For the detailed accounting method behind it, see hotel master bill reconciliation.
What a master bill audit checks
These are the areas FolioMatch reviews on every audit, where the documents contain the terms.
- —
Group room rate
Nightly rate by room type and date against the contracted group rate, including shoulder nights and any rate changes in addenda.
- —
Comp rooms and upgrades
Complimentary rooms earned under the comp ratio (for example 1 per 40 paid room nights), applied at the right rate. See concessions audit.
- —
Resort, facility and amenity fees
Fees the contract waived or capped still appearing on guest or master charges.
- —
Food and beverage
Banquet checks against the final BEO: menu price, guarantee versus actual count, and minimum-spend treatment. See BEO invoice reconciliation.
- —
Service charge and tax
The contracted service charge percentage, what it applies to, and whether tax is calculated on it where local rules require. See service charge audit.
- —
Meeting room rental
Rental waived on meeting a minimum, or charged at a rate different from the agreement.
- —
AV, Wi-Fi and technology
Equipment, labor and internet charges against the AV agreement or contracted discount.
- —
Staffing, labor and overtime
Bartenders, attendants, technicians and security against approved quantities and times, plus overtime against the stated rule.
- —
Attrition and minimums
Whether attrition or F&B shortfall charges follow the contract's formula and cutoff dates.
- —
Deposits and credits
Deposits, prepayments and credits that should reduce the balance due.

How to audit a master bill with FolioMatch
- 01
Upload the signed contract
Scanned PDFs are fine. Pages without a text layer are read with OCR, and unreadable pages are flagged rather than guessed.
- 02
Add BEOs, addenda and change orders
FolioMatch works out which version of each term applies and shows its reasoning. If the order of documents is unclear, the finding is marked Needs review instead of assumed.
- 03
Upload the final master bill
Upload the PDF. You can also add the hotel's CSV export if you have it, and it's checked against the PDF.
- 04
Review the findings
Each one is labeled Likely discrepancy, Needs review, Matches agreement or Insufficient evidence. Every one comes with its calculation and source pages.
- 05
Decide and document
Mark each finding as Confirmed issue, Not an issue, Need clarification or Resolved, then create a reconciliation report containing only what you choose to send the hotel.
Conservative by design
A master bill audit is only useful if you can defend it to the hotel. FolioMatch calls something a likely discrepancy only when the documents support it. A charge with no matching term, a deposit that may or may not have been applied, or an onsite staffing change without an approval document is marked Needs review, because missing paperwork doesn't prove a charge is wrong.
All dollar amounts are calculated with fixed formulas, not estimated. Each finding records its formula and inputs, so you can see exactly how the difference was reached.
Terms you'll see on a master bill
- Master account (master bill)
- The group's central account. Charges routed to it are paid by the organizer, not individual guests.
- Routing instructions
- The rules for which charges post to the master account and which go to individual guest folios.
- Banquet check
- The itemized charge for one catered function, usually tied to a BEO number.
- Group rate
- The negotiated nightly rate for rooms in the block, usually per room type.
- Comp ratio
- The contracted formula for complimentary rooms, such as 1 comp per 40 paid room nights.
- Service charge
- A percentage added to F&B and some services. It isn't always a gratuity, and it's often taxable.

Questions
How long does a master bill audit take?
Uploading takes a few minutes. Analysis usually finishes within minutes and depends on how many pages you upload. Reviewing findings takes as long as you want to spend: every one links to its source pages, so you don't have to search for them.
Does FolioMatch contact the hotel?
No. FolioMatch never contacts the hotel or sends anything on its own. You decide which findings go into the reconciliation report and whether to send it.
What if the hotel's bill is a scan?
Scanned pages are read with OCR. If a page still can't be read, FolioMatch tells you which page it is rather than inventing values.
Is this for the hotel's own accounts payable?
No. FolioMatch is for planners and organizers checking the bill a hotel or venue has sent them. It doesn't audit a hotel's supplier invoices.
Can I add a document I find later?
Yes. Add it to the same event and run the analysis again.
You negotiated the deal. Make sure you got it.
Upload your contract, BEOs and final hotel bill. FolioMatch shows what needs attention and the source evidence behind every finding.
