AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The night audit closes the hotel's business day by checking that every occupied room was charged, every restaurant and bar sale was posted, and every naira received by cash, POS or transfer matches the guest folios. Advance deposits are recorded as money owed to guests, not as revenue. Differences are written up and explained before the next day opens.
In many Nigerian hotels the day ends with a cashier handing over an envelope and a handwritten summary. The night audit replaces that with a routine that catches missing room charges, unposted bar bills, short cash and transfers that never arrived. It works the same for a 10-room guest house as for a large hotel, and much of it applies to a shortlet operator with several apartments.
What the night audit is for
- Confirm every occupied room has been charged for the night.
- Confirm every food and beverage (F&B) sale has been posted to a guest folio or paid.
- Match payments received to the method used: cash, POS card, transfer, or charge to a company account.
- Separate advance deposits and caution deposits from the day's revenue.
- Record taxes collected so they can be paid over on time.
- Explain every difference before the business date is closed.
Step by step
- Room count. Compare the front desk's list of occupied rooms with housekeeping's evening report. A room housekeeping says is occupied but has no charge is either an unregistered guest or a missed posting.
- Post room charges. Post the night's rate to every occupied room, checking rate codes against the booking.
- F&B outlets. Total the restaurant and bar checks and agree them to the outlet's sales summary. Each check should be either paid or charged to a room.
- Cash. Count the float and the takings separately. Compare takings with the cash payments recorded in the system.
- POS. Print the end-of-day batch report from each terminal and agree it to card payments recorded. Settlement to the bank usually comes later, so track it the next day.
- Transfers. Tick each transfer recorded on a folio against the bank statement or banking app, not against a guest's screenshot.
- Deposits. List deposits received today for future stays and caution deposits held. Neither is revenue yet.
- Close and report. Print the daily revenue report, sign the variance sheet, roll the date.
Worked example (labelled example)
| Revenue | ₦ |
|---|---|
| Rooms: 14 occupied at ₦45,000 | 630,000 |
| Restaurant and bar | 210,000 |
| Total revenue | 840,000 |
| Payments recorded | ₦ |
|---|---|
| Cash | 120,000 |
| POS cards | 380,000 |
| Bank transfers | 290,000 |
| Charged to company accounts (city ledger) | 50,000 |
| Total | 840,000 |
Separately, ₦150,000 arrived as deposits for next weekend's bookings. That sits in an advance deposits account until the guests check in. When the cashier counts, takings come to ₦115,000 against ₦120,000 recorded: a ₦5,000 shortage. The auditor writes it up with the cashier's explanation and the duty manager's signature. A shortage that is never written up becomes normal.
Taxes collected on the bill
In Lagos, the Lagos State Internal Revenue Service (LIRS) has said a 5% consumption tax applies to goods and services consumed in hotels, restaurants and event centres under the Hotel Occupancy and Restaurant Consumption Law. The business collects it from the guest as a collecting agent, must register with LIRS, and must remit by the 20th day of the following month using a monthly return, according to an October 2023 TechEconomy report quoting LIRS. Late remittance attracts a 10% penalty plus interest. On a ₦100,000 room bill, 5% is ₦5,000 (example).
VAT is charged at 7.5%, though the Nigeria Tax Act 2025 exempts small businesses with turnover up to ₦100 million and fixed assets up to ₦250 million from charging it, as summarised by Forvis Mazars in March 2026. Show each tax on its own line on the folio and post it to its own liability account so the night audit can total it. Other states have their own rules; check with your state revenue service. This is information, not tax advice.
Common variances and what they usually mean
| What you see | Likely cause | What to do |
|---|---|---|
| Occupied room with no charge | Walk-in not registered, or posting missed | Check the register and CCTV, post the charge, note who checked the guest in |
| Cash short | Change errors, unrecorded refund, or theft | Recount with the cashier present, sign the variance sheet, track repeat shortages by person |
| POS batch higher than card payments posted | Card payment taken but not posted to a folio | Find the folio, post it, check for double charging |
| Transfer on folio, not in bank | Fake alert or a payment still pending | Flag the folio, contact the guest before check-out |
| Bar sales lower than stock used | Unrecorded sales or giveaways | Compare bottles issued with checks; review complimentary approvals |
Look at variances over a month, not only night by night. A shortage of a few thousand naira that appears on the same cashier's shift every week is a pattern, not an accident.
Deposits and the guest ledger
Three balances confuse new operators. Advance deposits are money paid before arrival; they become revenue only when the stay happens. Caution deposits are refundable and should never be counted as income (see our guide to holding and refunding caution deposits). The city ledger is what companies owe you for guests you allowed to charge; chase it weekly. Hotels are also listed among sectors that register with SCUML, according to a Mondaq guide to hotel set-up, so large cash receipts need care.
Where Pryme fits
A Pryme Business Account can issue virtual account numbers so transfers can be told apart, and the Finance agent prepares a reconciliation for a person to approve. For the cash side, see how to do an end-of-day cash-up, and for shortlet tax, shortlet bookkeeping and tax.
Questions people ask
What does a night auditor do in a Nigerian hotel?
They close the business day: check every occupied room was charged, post restaurant and bar sales, match cash, POS and transfers to guest folios, separate deposits, and report differences.
Is a guest's advance deposit hotel revenue?
Not until the stay happens. Record it as money held for the guest and move it to revenue when they check in.
Do hotels in Lagos charge consumption tax?
LIRS has said a 5% consumption tax applies to hotels, restaurants and event centres, collected from guests and remitted by the 20th of the following month (TechEconomy, Oct 2023). Check current rules with LIRS.
How do I confirm a guest's transfer is real?
Check the credit in your own banking app or statement. Do not accept a screenshot or SMS as proof.
