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
Close the month by reconciling each bank account in its own currency, posting cut-off accruals, then revaluing naira monetary items such as the naira bank balance, receivables and payables at the closing rate, with the difference going to foreign exchange gains or losses. Non-monetary items such as prepaid rent or equipment stay at their original rate. Record the rate source and date so the revaluation can be checked.
The order of work
A close goes wrong when people revalue before they reconcile. The naira balance must be right in naira first; only then does converting it to dirhams mean anything. A workable order for a UAE company with AED as its functional currency and a naira account for Nigerian customers or suppliers:
- Reconcile every bank account in its own currency: the AED account to the AED statement, the naira account to the naira statement. Clear unexplained items, bank charges and transfer fees.
- Match receipts and payments to invoices so receivables and payables in each currency are correct.
- Post cut-off entries: goods received not invoiced, services delivered not billed, prepayments.
- Record realised exchange differences on invoices settled during the month.
- Revalue the remaining naira monetary items at the month-end closing rate.
- Review the exchange gain or loss line, then lock the period.
What IAS 21 says about the revaluation
Under IAS 21 paragraph 21, a foreign-currency transaction is first recorded at the spot rate on the transaction date; paragraph 22 allows an average rate for a period if rates have not fluctuated significantly. At each reporting date, paragraph 23 says foreign-currency monetary items are translated at the closing rate, while non-monetary items carried at historical cost stay at the rate on the transaction date. Paragraph 28 sends exchange differences on settling or retranslating monetary items to profit or loss in the period they arise.
| Naira item | Monetary? | Month-end rate |
|---|---|---|
| Naira bank balance | Yes | Closing rate |
| Receivable from a Lagos customer | Yes | Closing rate |
| Unpaid invoice from a Nigerian supplier | Yes | Closing rate |
| Deposit paid for a Lagos warehouse lease (refundable in naira) | Usually yes | Closing rate |
| Rent paid in advance for the Lagos office | No | Rate on payment date |
| Laptops bought in Nigeria | No | Rate on purchase date |
A refundable deposit is a judgement call that depends on its terms; agree the treatment with your auditors once and apply it every month. The general mechanics are also set out in revaluing naira balances at month end.
Choosing and recording the closing rate
IAS 21 does not name a source. Paragraph 26 says that where several rates exist, use the rate at which the future cash flows could have been settled at the measurement date. For a UAE company that actually converts naira through its bank or payment provider, that points to a rate you could have dealt at, not a headline figure. Pick one source, write it in your accounting policy, and record the rate and its timestamp in the close file each month. The choice of source is discussed in which naira rate to use in UAE books.
Worked example
Example, with invented rates. On 31 May the company holds ₦20,000,000 in its naira account. It was carried at AED 0.00250 per naira, so AED 50,000. A Lagos customer owes ₦8,000,000, carried at AED 0.00245, so AED 19,600. The closing rate on 31 May is AED 0.00240.
- Bank: 20,000,000 x 0.00240 = AED 48,000. Loss of AED 2,000.
- Receivable: 8,000,000 x 0.00240 = AED 19,200. Loss of AED 400.
- Total unrealised exchange loss for May: AED 2,400, debited to exchange differences in profit or loss.
- If the customer pays ₦8,000,000 in June when the rate is AED 0.00238, the June gain or loss is measured from AED 19,200, not from the original AED 19,600 (IAS 21 paragraph 29).
The review pack
The reviewer, whether a finance manager or the owner, should see on one page: each bank reconciliation with unreconciled items listed; aged receivables and payables in each currency; the closing rate used with source and time; the revaluation workings; and the month's exchange gain or loss compared with the movement in the rate. A large naira loss with a small rate movement means a balance or a rate is wrong. Common errors to look for: a transfer fee posted in naira to the AED account, a customer receipt recorded twice because it arrived in naira and was then converted, and an exchange difference posted manually on top of the automatic revaluation. Keep supporting documents in a form auditors can rely on; see receipts and the audit trail.
Where Pryme fits
A Pryme Business Account holds naira alongside USD, GBP and EUR with local account details for each, so statements for each currency come from one place. It does not hold dirhams, so the AED side stays with your UAE bank. Money stays in the currency it arrived in until you choose to Swap; the rate and fee are shown before you approve. The Finance agent can prepare reconciliations and revaluation workings for your review.
Questions people ask
Do I revalue the naira bank balance every month?
If you produce monthly accounts, yes. IAS 21 requires monetary items to be translated at the closing rate at each reporting date, with differences in profit or loss.
Is prepaid rent in naira revalued?
No. Prepaid rent is a non-monetary item and stays at the rate on the payment date under IAS 21 paragraph 23.
Which rate do I use at month end?
IAS 21 does not name a source. Where several rates exist it points to the rate at which the cash flows could be settled. Choose a source, document it and use it consistently.
Does the month-end rate change my VAT figures?
No. VAT amounts follow the FTA rule on the UAE Central Bank rate at the date of supply, according to EY's summary of VATP004.
