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
Forecast each currency separately, then convert the net naira position under at least three labelled scenarios (rate unchanged, a moderate move and a severe move) instead of one predicted rate. Pair that with a rolling 13-week cash view, inflation-adjusted naira costs and the timing limits on moving money, so decisions rest on ranges you can act on rather than a single number that will be wrong.
A business run from abroad with operations in Nigeria lives with two clocks: revenue often arrives in pounds, dollars or euros, while rent, salaries, fuel and suppliers are paid in naira. When the exchange rate moves sharply, a forecast built on one assumed rate tells you very little. The aim is not to predict the naira. It is to know, in advance, what happens to your cash under several plausible paths and what you would do in each.
Forecast in the currency each cash flow happens in
Start with separate schedules: naira inflows and outflows, and foreign-currency inflows and outflows. Do not convert anything at this stage. A Lagos landlord invoices in naira; a UK customer pays in pounds. Keeping them apart shows your true exposure, which is the net naira you must buy (or sell) each week.
- Naira outflows: payroll, PAYE, pension, rent, diesel and power, supplier runs, statutory remittances.
- Naira inflows: local sales, which under the CBN Foreign Exchange Manual 2026, as TheCable reported, must generally be priced and settled in naira between Nigerian parties.
- Foreign-currency flows: overseas revenue, foreign suppliers, loan repayments.
- Net naira need: naira outflows minus naira inflows, week by week.
Scenario methods that work
1. Three or four rate paths
Take today's rate as the base, then apply labelled moves to it. A common set is: unchanged; naira 10% weaker; naira 25% weaker; and, for a business with naira revenue, naira 10% stronger. You are not saying any of these will happen. You are testing whether the business survives each one. Never hard-code a rate into the model; keep one input cell for today's rate and update it from your bank or the rate your provider shows before each review.
2. Inflation on naira costs
A weaker naira usually comes with rising naira prices, so a scenario that moves only the exchange rate understates costs. The National Bureau of Statistics put headline inflation at 14.63% year on year for September 2026, down from 15.39% in August, and food inflation at 19.59%, as reported by Voice of Nigeria on 16 October 2026. Use the latest NBS release as a floor for annual cost growth on wages, food-linked costs and rent at renewal, and a higher figure in the severe scenario.
3. A rolling 13-week view
Annual budgets are too slow for a volatile currency. A 13-week cash forecast, updated every Monday, captures the actual dates when salaries, PAYE and pension fall due and when foreign receipts land. Pension contributions, for instance, must be remitted within seven working days of paying salaries under the Pension Reform Act 2014, so they sit in the same week as payroll.
4. Timing and movement limits
A forecast is only useful if money can move when the model says it will. TheCable's summary of the 2026 FX Manual says domiciliary account holders may make telegraphic transfers of up to $10,000 a day. For naira payments, a CBN circular effective 1 July 2026, reported by Proshare, sets maximum instant transfer thresholds of ₦25 million for individuals and ₦250 million for corporates, adjustable within those limits. Build these into the dates, not just the amounts.
A worked example
Example only. A UK-registered company owns a Lagos subsidiary. Lagos costs are ₦30 million a month. At today's rate (call it R), that equals £15,000. UK revenue is £22,000 a month, and UK costs are £5,000.
| Scenario | Naira costs | Cost in pounds | Monthly surplus |
|---|---|---|---|
| Rate unchanged, no inflation | ₦30.0m | £15,000 | £2,000 |
| Naira 10% weaker, costs +5% | ₦31.5m | £14,318 | £2,682 |
| Naira 25% weaker, costs +15% | ₦34.5m | £13,800 | £3,200 |
| Naira 10% stronger, costs +5% | ₦31.5m | £17,500 | -£500 |
How the figures work: cost in pounds = £15,000 × (naira cost ÷ ₦30m) ÷ (how many times more naira each pound buys). A 10% weaker naira means each pound buys 1.1 times as many naira, so £15,000 × 1.05 ÷ 1.1 = £14,318. In the 25% case, £15,000 × 1.15 ÷ 1.25 = £13,800. A 10% stronger naira means each pound buys 0.9 times as many, so £15,000 × 1.05 ÷ 0.9 = £17,500. The surplus is £22,000 revenue less £5,000 UK costs less the Lagos cost in pounds.
The point of the example: a company with pound revenue and naira costs is hurt more by a stronger naira with sticky local inflation than by a weaker one, which is the opposite of what many owners assume. A business with naira revenue and foreign-currency costs faces the reverse.
What to check first
- Split every cash line by the currency it is paid in.
- Set one input cell for today's rate and refresh it before each review.
- Run at least three labelled scenarios, including one where the naira strengthens.
- Apply the latest NBS inflation figure to naira costs.
- Map payment dates against bank and FX transfer limits.
- Decide in advance what you will do in each scenario: delay capital spending, convert earlier, or renegotiate a contract.
For the accounting side, see which naira rate to use in your books and revaluing naira balances at month end. If the scenarios show a gap you cannot carry, read the hedging options open to a small business.
Where Pryme fits
A Pryme Business account holds NGN, USD, GBP and EUR in one place, so the forecast's currency buckets match real balances. Swap converts only when you choose, with the rate shown and the fee on its own line before you approve. The Finance agent can prepare the weekly forecast refresh from actual balances for you to review.
Questions people ask
How often should I update a naira cash flow forecast?
Weekly for the 13-week view, with today's rate refreshed before each review. Annual budgets are too slow when the rate moves sharply.
What exchange rate should I use in a forecast?
Today's rate as a base, then labelled scenarios around it. Do not rely on a single predicted rate.
Does a weaker naira always hurt a diaspora-owned business?
No. If revenue is in pounds or dollars and costs are in naira, a weaker naira can reduce costs in foreign-currency terms, though local inflation offsets part of it.
Which inflation figure should I use for Nigerian costs?
The latest NBS headline release as a floor, with food inflation for food-linked costs. September 2026 headline was 14.63%.
