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
Before you pay a Nigerian supplier, an AI agent can check the invoice against what you already know: is it a duplicate, does it match the purchase order and contract, are the supplier's name, tax ID and bank details the ones on file, and is the currency and amount right? It flags anything odd for a person to decide. Changes to bank details should always be confirmed by phone on a number you already hold, never by replying to the email.
Why supplier invoices need checking
A Canadian business paying many Nigerian suppliers, such as developers, designers, logistics agents and fabric traders, faces the same risks as any business plus a few of its own. Invoices arrive by email, WhatsApp or PDF in a dozen layouts. The same freelancer may bill under a personal name one month and a business name the next. Payments cross currencies, so a wrong figure is harder to spot. And a request to "use our new account" is one of the oldest frauds there is. The goal of checks is simple: pay the right person, the right amount, once.
The checks an agent can prepare
Duplicate checks
- Same supplier, same invoice number.
- Same supplier, same amount, within a short window, even with a different invoice number.
- Same amount and date from two supplier records that may be the same person.
- An invoice already paid by a different route, such as a cash advance a Lagos manager made.
Detail checks
- Supplier name and address match the supplier record and the contract.
- Amount, currency and rate agree with the purchase order or contract; the agent shows the difference rather than rounding it away.
- For VAT-registered Nigerian suppliers, the invoice carries the section 153 VAT invoice details: supplier's tax ID and registration number, invoice number, name and address, date of supply, your name, gross amount, and VAT charged and rate (Nigeria Tax Act 2025, as summarised by Mondaq, May 2026).
- If Nigerian VAT is charged on a service you use in Canada, flag it, since exported services are generally zero-rated; see whether Nigerian VAT applies to services sold to a Canadian firm.
- The invoice is in English or French, or has a translation attached, because the CRA requires records in one of those languages.
Payment detail checks
- Bank account name and number match the supplier record exactly.
- Any change of account, however it arrives, is held until confirmed by a call to a number already on file.
- The account name on the destination matches the supplier, not a third party.
- The payment does not exceed the approval ceiling for the person who requested it.
Supplier record checks
Checks work only if the supplier record is right in the first place. When a Nigerian supplier is first set up, confirm its legal or trading name, its Tax ID where it has one, its bank account in its own name, and a phone number you have verified by calling. The agent then compares every later invoice with that record rather than with whatever the latest email says.
What a person decides
The agent's output is a short list: invoices that passed every check, and invoices with flags and the reason for each. A person reviews the flags and either clears, corrects or rejects. Rules worth writing down:
- No bank detail change is accepted on the strength of an email or message alone, even from a known address.
- Invoices over a set amount need a second approver.
- A supplier who refuses to give a proper invoice is paid only after a manager agrees.
- Every override is recorded with a reason.
Worked example
Example only. A Montreal e-commerce firm receives 38 Nigerian supplier invoices in a week. The agent clears 33. It flags five: two possible duplicates (same freelancer, same amount of ₦450,000, invoice numbers 0112 and 0113, three days apart); one invoice in USD from a supplier always paid in naira; one invoice adding 7.5% Nigerian VAT on design work for the Canadian website; and one email asking for payment to a new account. The bookkeeper confirms one duplicate was a genuine second job, rejects the other, asks the USD supplier to reissue, queries the VAT, and calls the last supplier on the number held, who confirms the account has not changed. The fraud attempt is stopped by a phone call, not by software.
Records for the CRA
Keep the invoice, the checks and the approval with the payment record. The CRA requires records supported by documents and kept for six years from the end of the tax year, in Canada unless it gives written permission otherwise. For a GST/HST-registered business claiming ITCs on Canadian purchases, the CRA's input tax credit page lists what an invoice of $500 or more must show, including the supplier's GST/HST registration number, your name, a description and payment terms. More on Nigerian receipts in what receipts the CRA accepts for Nigerian supplier costs.
Where Pryme fits
The Finance agent that comes with a Pryme Business Account, built by Pryme Intelligence, prepares these checks before a payment run; a person approves above a set ceiling and every action is recorded. Approved payments can go out together through bulk payouts from NGN, USD, GBP or EUR balances. Account security uses an authenticator app rather than SMS codes, plus a transaction PIN (security).
Questions people ask
Can AI catch duplicate supplier invoices?
Yes, it can flag exact duplicates and near-duplicates such as the same amount from the same supplier within days. A person decides whether a flagged invoice is a genuine second job.
How do I stop payment to a fake bank account?
Never accept a change of bank details by email or message alone. Hold the payment and call the supplier on a number you already have on file.
What should a Nigerian VAT invoice show?
Under section 153 of the Nigeria Tax Act 2025, as summarised by Mondaq, the supplier's tax ID and registration number, invoice number, name and address, date of supply, buyer's name, gross amount and VAT charged and rate.
Should every invoice be approved by a person?
At minimum, every flagged invoice and every invoice above a set ceiling. Many businesses also require a second approver for large amounts.
