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
Set the budget in US dollars, keep every naira cost line in naira, and convert them at one documented planning rate rather than a guess. Add a buffer for naira movement, review actual rates monthly against the plan, and report variance from price changes separately from variance caused by the exchange rate.
A US-Nigeria business usually reports in dollars, raises money in dollars and often sells in dollars, while rent, salaries, diesel, data and many suppliers are priced in naira. Budgeting it as if everything were in one currency hides the biggest risk in the plan. This guide sets out a structure that keeps the two currencies visible and makes variances explainable to a board or investor.
Keep naira lines in naira
The most common mistake is to type naira costs into the budget already converted to dollars. Once that is done, nobody can tell whether a cost overran because the landlord raised the rent or because the naira moved. Hold each naira line in naira in the source sheet, with a separate conversion step.
| Line | Currency of cost | How to budget it |
|---|---|---|
| Lagos salaries and statutory contributions | NGN | In naira, by person, with review dates |
| Office rent and service charge | NGN (sometimes quoted in USD) | In the currency of the lease |
| Electricity, diesel, data, cable | NGN | Monthly naira estimate from recent bills |
| Software subscriptions | Usually USD | In dollars, even if paid by a Nigerian card |
| US payroll, legal, audit | USD | In dollars |
Choose and document a planning rate
The CBN publishes the Nigerian Foreign Exchange Market (NFEM) rate, which its rates page describes as derived at volume-weighted average and the official exchange rate for the day. For orientation only: Nairametrics reported an NFEM close of ₦1,332.75 to the dollar on 7 October 2026, and Techeconomy reported ₦1,332.47 for 13 October 2026, with parallel-market quotes a little higher. Those figures will have moved by the time you read this; check the NFEM explainer and the CBN page for today’s number.
Pick one planning rate for the budget year, write down its source and date, and use it everywhere. Some teams use the rate on the day the budget is approved; others use a weaker rate as a deliberate cushion. Either is defensible if it is written down.
Build the buffer the right way round
If your revenue is in dollars and costs are in naira, a weaker naira makes those costs cheaper in dollars, and a stronger naira makes them dearer. The buffer you need is against the naira strengthening, and against naira prices rising faster than the currency weakens, which is common for imported items such as diesel and equipment.
Worked example (illustrative figures)
Example only. Monthly naira costs are ₦40,000,000. At an example planning rate of ₦1,350 per dollar that is about $29,630. If the naira strengthens to an example ₦1,250, the same costs become $32,000, an increase of about $2,370 a month. If, separately, naira prices rise 5% to ₦42,000,000, at ₦1,350 that is about $31,111. A budget that holds both variables apart lets you say which of these happened.
Monthly re-forecast
- Record actual naira spend by line, in naira.
- Record the rate at which you actually converted dollars into naira that month.
- Split the variance: price variance (actual naira minus budget naira, at the planning rate) and FX variance (actual naira at actual rate minus actual naira at planning rate).
- Update the forecast for the remaining months, keeping the original budget unchanged for comparison.
- Show both variances in the management pack.
The accounting treatment of naira balances in your US books is a separate topic; see FX gains and losses on naira balances. For tax reporting, the IRS says amounts must be reported in US dollars, it has no official exchange rate, and it generally accepts any posted rate used consistently.
Capital items and imported costs
Generators, inverters, laptops and solar equipment are usually priced in naira by Lagos sellers but follow the dollar closely, because most are imported. Budget them in dollars with a naira estimate beside them, and get a dated quote before the budget is approved. If a supplier quotes in naira, ask how long the quote holds; many hold for days, not months. For large purchases, decide in advance whether you will convert the dollars at order or at delivery, and record which.
Common mistakes to avoid
- Using a rate from a news headline without a source and date.
- Converting a naira budget once in January and never looking at the rate again.
- Mixing naira prices quoted with VAT and without VAT in the same line.
- Forgetting statutory employer costs on top of gross salaries, such as pension, NSITF and ITF.
- Treating a dollar-quoted rent as a naira cost, or the reverse.
Salaries need their own rule
Staff costs are usually the largest naira line. Decide in the budget whether pay is fixed in naira, reviewed on set dates, or linked to the dollar, because each choice moves FX risk between the company and the employee. See USD-linked salaries before you promise anything in an offer letter.
Where Pryme fits
A Pryme Business Account holds NGN, USD, GBP and EUR with local account details for each, and money stays in the currency it arrived in until you convert it with Swap. The app shows the rate and the fee before you approve, which gives you the actual conversion rate for step 2 of the re-forecast. The Finance agent can prepare the monthly variance work for a person to review.
Questions people ask
What exchange rate should I use for a Nigerian budget?
Use one documented planning rate for the year, with its source and date. Many businesses start from the CBN’s NFEM rate on the approval date and add a cushion. Never leave the rate undefined.
Should I budget naira costs in dollars?
Keep them in naira in the working budget and convert them in a separate step. That way you can tell price increases apart from exchange rate movements.
Is a weaker naira good or bad for my budget?
If revenue is in dollars and costs in naira, a weaker naira lowers costs in dollars, but imported goods often rise in naira price at the same time. Budget for both effects.
How often should a two-currency budget be re-forecast?
Monthly is common for businesses with large naira costs, recording actual naira spend and the actual conversion rate each month.
