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
Give each entity its own ledger in its own functional currency, usually AED for the UAE company and naira for the Nigerian one, decided by the IAS 21 test of the currency of sales prices and costs. Build one shared chart of accounts with separate bank and intercompany accounts for each currency, switch on multicurrency so foreign balances are revalued automatically, and record the rate source used for each purpose.
Step 1: decide each entity's functional currency
IAS 21 paragraph 8 defines functional currency as the currency of the primary economic environment in which the entity operates. Paragraph 9 gives the main indicators: the currency that mainly influences sales prices, and the currency that mainly influences labour, material and other costs. Paragraph 10 adds supporting indicators such as the currency of financing and of retained receipts, and paragraph 12 says management uses judgement, giving priority to paragraph 9.
For most groups the answer is simple: the UAE company sells and pays staff in dirhams, so AED; the Lagos company sells in naira and pays Nigerian staff, so naira. The hard case is a Nigerian company that prices everything in dollars and pays key costs in dollars; its functional currency may be the dollar even though it is Nigerian. Decide this on the facts, write it down and do not change it casually, because paragraphs 35 to 37 say a change applies prospectively from the date of change.
Step 2: one chart of accounts, many currencies
Use the same account codes in both entities so reports line up, and add currency-specific accounts only where the balance really is in another currency.
| Account | UAE entity (AED books) | Nigerian entity (naira books) |
|---|---|---|
| Bank | Bank AED; Bank USD; Bank NGN if held | Bank NGN; Bank USD (domiciliary) |
| Receivables | Trade debtors AED; Trade debtors NGN | Trade debtors NGN; Trade debtors USD |
| Intercompany | Due from Nigerian subsidiary (in the agreed loan or invoice currency) | Due to UAE parent (same currency) |
| FX | Realised FX gain/loss; Unrealised FX gain/loss | Realised FX gain/loss; Unrealised FX gain/loss |
| Tax | UAE VAT input; UAE VAT output | Nigerian VAT input; Nigerian VAT output; WHT payable; WHT receivable |
The intercompany pair must be in the same currency in both ledgers. If the parent records a dollar receivable and the subsidiary records a naira payable, the two will never agree. Agree the currency in the loan agreement or service contract and set both accounts to it. For invoices between the entities, see intercompany invoices between Nigeria and abroad.
Step 3: currency settings in the software
- Set the base currency of each file to that entity's functional currency. In most packages this cannot be changed later.
- Enable multicurrency and add NGN, USD, AED and any others you use. Confirm your package supports naira before you commit; this was not checked for this article.
- Choose the rate feed for transactions and for month-end revaluation, or decide to enter rates manually from a documented source.
- Turn on automatic revaluation of foreign-currency monetary accounts at period end, which matches IAS 21 paragraph 23.
- Lock periods after close so revaluations are not overwritten.
Step 4: keep separate rate records for separate rules
Three rates may be in play. For UAE VAT, EY's summary of FTA clarification VATP004 says foreign-currency invoices are converted at the UAE Central Bank rate on the date of supply. For the accounts, IAS 21 uses spot and closing rates, and where several rates exist the rate at which cash flows could be settled. For consolidation, each entity's results are translated into the group's presentation currency under IAS 21. Keep a rate table in the file with date, source and purpose so a reviewer can see which number was used where. The choice is explained in which naira rate for UAE books.
Step 5: Nigerian reporting requirements
According to the IFRS Foundation's Nigeria profile, Nigeria adopted IFRS from 2012 for listed and significant public interest entities, with other public interest entities following and SMEs using IFRS for SMEs from 2014. The Nigerian entity's statutory accounts follow Nigerian rules even if the group reports differently. Large Nigerian taxpayers also face e-invoicing through the NRS platform; The Guardian reported a 31 July 2026 deadline for taxpayers with turnover of ₦5 billion or more, so check whether your subsidiary is in scope and whether your software connects to an approved provider.
Worked example
Example, invented figures. The UAE parent invoices its Lagos subsidiary USD 10,000 for management services. In the parent's AED books, the receivable is recorded at the spot rate, say AED 3.6725 per dollar, AED 36,725. In the subsidiary's naira books, the payable is recorded at its spot rate, say ₦1,500 per dollar, ₦15,000,000. Both ledgers carry a USD 10,000 intercompany balance, so they agree in dollars; each revalues it at its own month-end rate. Nigerian withholding tax on the fee is a separate entry; see WHT on management fees to a UAE parent.
Where Pryme fits
A Pryme Business multicurrency account holds NGN, USD, GBP and EUR with local details for each, which keeps the Nigerian entity's naira and dollar bank feeds in one place. The Finance agent can prepare the month-end rate table and intercompany reconciliation for a person to approve.
Questions people ask
Can a Nigerian subsidiary keep its books in dollars?
Only if the dollar is its functional currency under IAS 21, judged mainly by the currency of its sales prices and costs. Statutory Nigerian requirements still apply.
Should both entities use the same chart of accounts?
It helps. Shared codes make consolidation and intercompany matching simpler; add currency-specific bank and debtor accounts where needed.
Why don't our intercompany balances agree?
Usually because the two ledgers record the balance in different currencies or at different rates. Set both sides to the agreed contract currency.
Do I need different rates for VAT and the accounts?
Possibly. UAE VAT follows the UAE Central Bank rate rule described in FTA clarification VATP004, while the accounts follow IAS 21.
