Night Audit Process: A Step-by-Step Guide for Hotel Staff

The night audit is the heartbeat of hotel accounting. Every day, dozens of transactions flow through a property — room charges, restaurant bills, spa payments, minibar consumption, laundry services, payment collections, and adjustments. The night audit brings all of this together, reconciles it, and produces the reports that management relies on to run the business.

Despite its importance, the night audit is often the least trained procedure in hotel operations. Night auditors are frequently asked to "just run the audit" without understanding why each step matters. This guide breaks the entire process into four clear phases that any front desk team member can follow.

What is a Night Audit?

The night audit is the end-of-day accounting process that:

• Posts room charges and taxes to all in-house guest folios for the current night
• Reconciles all revenue from every department (rooms, F&B, spa, etc.) against the PMS
• Resolves discrepancies in guest accounts, billing, and payment records
• Generates management reports — the Daily Business Summary, revenue breakdown, occupancy statistics, and department-wise performance
• Advances the business date — closing today and opening tomorrow in the PMS

The audit typically runs between 11 PM and 3 AM (the "audit window"), chosen because it's the period with the least guest activity. Once the audit runs, today's transactions are locked and the PMS moves to the next business day.

Phase 1: Pre-Audit Checks

Before running the audit, the night auditor must verify that all day's transactions are complete and accurate.

1.1 Verify Room Status

• Confirm all expected arrivals for today have either checked in or been marked as no-shows
• Verify all departures for today have been checked out
• Reconcile the PMS room count with physical occupancy — walk the property if necessary to confirm occupied rooms match the system
• Flag any rooms showing as occupied in the PMS but reported vacant by housekeeping (sleepers/skippers)

1.2 Review Pending Transactions

• Check for unposted restaurant charges — the F&B POS should have pushed all bills to the PMS
• Verify spa and activity charges are posted to the correct folios
• Review minibar consumption reports from housekeeping and post any outstanding items
• Check for pending laundry charges

1.3 Handle No-Shows

• Identify guaranteed reservations that did not check in
• Apply no-show charges per the reservation's cancellation policy
• Release the room inventory back to available
• Document the no-show with reservation ID and reason if known

1.4 Verify Rate Integrity

• Review the rate variance report — flag any rooms with rates significantly above or below the expected range
• Confirm all complimentary and house-use rooms have proper authorization codes
• Verify group rates are posting correctly per the group contract

Phase 2: Revenue Posting

This is the core mechanical step where the PMS calculates and posts tonight's charges to every active folio.

2.1 Room Charge Posting

The PMS calculates each room's charge based on its assigned rate plan, applies any adjustments (discounts, packages), and posts the room revenue to the folio. Each posting should include:

• Room charge (net of any included components like breakfast)
• Applicable taxes (GST in India — typically 12% or 18% based on room tariff)
• Package inclusions posted as separate line items for reporting accuracy

2.2 Recurring Charges

Post any scheduled recurring charges — extra bed charges, crib rental, parking, internet packages, or other daily fixed charges attached to specific reservations.

2.3 Tax Posting

Verify that taxes are calculated correctly per the property's tax configuration. In India, hotel GST rates depend on the declared room tariff:

• Room tariff up to ₹7,500: 12% GST
• Room tariff above ₹7,500: 18% GST

The PMS should handle this automatically based on the rate assigned, but the night auditor should spot-check a few rooms to confirm correct tax posting.

Phase 3: Reconciliation

After posting, the auditor reconciles all accounts to ensure everything balances.

3.1 Trial Balance

Run the trial balance report. All debits (charges posted to guest accounts) must equal all credits (payments received plus outstanding balances). If the trial balance doesn't zero out, there's a posting error that must be found and corrected before proceeding.

3.2 Cashier Reconciliation

• Each cashier's shift should be closed and balanced
• Cash collections must match cash register totals
• Credit card settlements must match terminal batch totals
• UPI and digital payment receipts must reconcile with the PMS

3.3 Department Revenue Reconciliation

Cross-check each department's reported revenue against PMS postings:

• Rooms: Total room charges posted should equal the sum of all rate × occupied rooms
• F&B: POS total should match PMS postings for restaurant charges
• Spa: Spa management system total should match PMS spa postings
• Others: Minibar, laundry, telephone, activities — cross-reference source reports

3.4 High-Balance Review

Review guest accounts with high outstanding balances. Flag any accounts that exceed the guest's credit limit or prepayment. These are potential bad debt risks and should be communicated to the morning shift for follow-up.

Phase 4: Reports & Date Rollover

4.1 Generate Management Reports

The night audit produces the daily reports that management reviews each morning:

• Daily Business Summary (DBS): The single-page snapshot of the day — occupancy, ADR, RevPAR, room revenue, total revenue, arrivals, departures, no-shows
• Revenue Report: Department-wise revenue breakdown with comparison to budget and last year
• Room Status Report: Current occupancy, out-of-order rooms, expected arrivals/departures for tomorrow
• Guest Ledger Report: All outstanding guest balances
• City Ledger Report: Corporate and travel agent outstanding balances
• Cashier Summary: Payment collections by mode (cash, card, UPI, bank transfer)

4.2 Date Rollover

Once all verifications are complete and reports generated, the auditor executes the date rollover. This is an irreversible action — once the date advances, you cannot repost or modify the previous day's transactions (corrections must be made as adjustments in the new day). Always ensure everything is verified before rolling the date.

4.3 Post-Rollover Checks

• Confirm the PMS business date has advanced correctly
• Verify that tomorrow's arrivals are visible and that room assignments are in order
• Check that any maintenance or out-of-order rooms are correctly reflected
• Leave a handover note for the morning shift documenting any unresolved issues, VIP arrivals, and special instructions

Common Night Audit Issues & Solutions

• Late restaurant charges: The restaurant closes at 11 PM but the audit runs at midnight. Solution: establish a cutoff time for F&B to close their POS and push all charges to the PMS. Late orders are posted in the next day.
• Rate discrepancies: A guest was quoted one rate but the PMS shows another. Solution: check the reservation history for rate changes. If the current rate is wrong, correct it before the audit runs — post-audit corrections require adjustments.
• Walk-in guests with no rate: A guest checked in without a rate being assigned. Solution: the night auditor cannot guess rates. Contact the duty manager or apply the default walk-in rate per property policy.
• Credit card settlement failures: A card pre-authorization expired or was declined. Solution: flag the room for morning follow-up. Do not block the audit — run it and note the issue in the handover.
• Trial balance mismatch: Debits don't equal credits. Solution: check the adjustment log for manual postings. Review the day's corrections. Compare department totals line by line until the discrepancy is found.

Night Audit Automation

Modern cloud PMS platforms automate the mechanical steps of the night audit, reducing a 2-3 hour process to 15-30 minutes of human review:

• Auto-posting: Room charges, taxes, and recurring charges post automatically at the scheduled time
• Auto-reconciliation: The PMS cross-checks department totals and flags discrepancies automatically
• No-show detection: Unredeemed guaranteed reservations are flagged for review
• Report generation: All management reports generate automatically, often available in a dashboard before the auditor finishes their review
• Date rollover: Executes automatically after a confirmation step

Automation doesn't eliminate the auditor — it elevates them from data entry to exception management. The human focuses on judgment calls: is this rate correct? Should this no-show be charged? Does this high-balance account need escalation?
