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
For goods exported to Canada, a US dollar invoice usually fits Nigeria's rules better, because the exporter must repatriate foreign currency proceeds into its domiciliary account. A naira invoice moves the exchange risk to you as the naira moves, while a USD invoice leaves you with USD/CAD risk. Either way, your Canadian declaration converts the invoice value into Canadian dollars, so the invoice currency and amount must match what you actually paid.
Why the question matters
Currency is a commercial term like price and delivery date. It decides who absorbs a currency move between order and payment, how the supplier's bank treats the money, and what your customs declaration shows. Getting it wrong can cost more than the margin on the order.
The Nigerian side: export proceeds
A Nigerian exporter of commercial goods files an e-Form NXP and must repatriate the proceeds through the banking system into its domiciliary account. Under the CBN Foreign Exchange Manual 2026, effective 1 June 2026, that must happen within 90 days for non-oil exports (180 days for oil and gas), replacing the 180-day non-oil window in a January 2025 circular. TheCable's June 2026 report on the Manual also notes that Nigerian entities must price and settle domestic transactions in naira, with sector exemptions, and that cash withdrawals of export proceeds are prohibited.
Put together, a formal exporter is expecting foreign currency for an export, which is why many quote in US dollars. A small seller who does not file an NXP may quote in naira because that is what its costs are in. If a supplier asks for naira for a formal export, ask how its bank will match the receipt to its NXP; that is the supplier's compliance question, but a mismatch can delay your goods.
Who carries the risk
| Invoice currency | Your risk | Supplier's risk |
|---|---|---|
| Naira | Naira strengthens against CAD before you pay: you pay more CAD | Small: costs and price are in the same currency |
| US dollar | USD strengthens against CAD before you pay | Naira strengthens against USD: its costs rise in USD terms |
| Canadian dollar (rare) | None on the invoice | All of it |
Worked example
Example only, invented rates. A Vancouver importer orders fabric for ₦8,000,000 with payment in 60 days. At order, ₦1,000 costs C$0.90, so the bill is C$7,200. If the naira strengthens and ₦1,000 costs C$0.99 on payment day, the bill is C$7,920, C$720 more. Had the supplier quoted US$5,200 instead, and USD/CAD stayed the same, the CAD cost would not move with the naira at all. If the naira weakened, the naira invoice would have been cheaper. Neither choice is free of risk; they are different risks. Check: 8,000 × 0.90 = 7,200; 8,000 × 0.99 = 7,920.
The Canadian side: customs value
Your declaration to the CBSA states the value of the goods, converted to Canadian dollars, and the CBSA's import guide reminds importers that they remain responsible for later corrections to value. Three practical rules follow:
- Make sure the commercial invoice states the currency clearly, not just a figure.
- Pay the amount on the invoice. If the price changes, get a revised invoice rather than paying a different figure.
- Ask your broker which exchange rate is applied and on which date, and keep it with the entry.
On the Nigerian side, the Nigeria Customs Valuation Guide 2026 applies the CBN official rate at the time a declaration is submitted, which matters to Nigerian importers but not to your Canadian entry.
What to write into the order
Whatever currency you choose, put it in writing in the purchase order or contract, not just in a chat. A short clause list covers most disputes:
- The currency of the price, written as a code (NGN, USD) beside every figure.
- Who pays bank charges on each side, so the supplier is not short-paid by an intermediary deduction.
- The account the payment goes to, in the supplier's name, and how a change of account will be confirmed.
- Payment dates tied to events you can prove: order confirmation, the bill of lading date, arrival.
- What happens if the currency moves beyond an agreed band before payment.
If the supplier issues a proforma first and a commercial invoice later, check that both carry the same currency. A proforma in naira and a final invoice in dollars, at a rate the supplier chose, is a common source of confusion at customs and in your books, where you will record the Canadian dollar cost actually paid.
Ways to reduce the risk
- Shorter payment terms: less time for rates to move.
- Fix the rate at order: buy the currency when you confirm the order and hold it until payment.
- Split the order: deposit on order, balance on shipment.
- Price clauses: agree that a move beyond a set band reopens the price.
For how Nigerian sellers set prices when the naira moves, see pricing when the naira keeps moving. For the payment itself, see how a Canadian business pays a Nigerian supplier.
Where Pryme fits
A Pryme Business Account holds naira and US dollars side by side, and money stays in the currency it arrived in until you choose to convert. With Swap you can buy the invoice currency when you confirm an order; the rate is shown first and the fee on its own line before you approve.
Questions people ask
Is it better to pay a Nigerian supplier in naira or dollars?
It depends on who should carry the currency risk and on the supplier's export obligations. Formal exporters usually need USD into a domiciliary account.
Can a Nigerian exporter invoice a Canadian buyer in naira?
Nigerian export rules expect foreign currency proceeds. Ask the supplier how its bank will treat a naira receipt against its NXP.
What exchange rate does Canadian customs use?
Your declaration converts the invoice to Canadian dollars. Ask your broker which rate and date apply and keep the record.
How do I protect against the naira moving before I pay?
Shorten terms, buy the currency at order, split payments or agree a price-review clause.
