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
To prove a business payment in Nigeria, send the supplier a remittance advice that lists the invoices paid, the amount, the date and the transfer reference, together with a receipt from your bank or provider. Ask the supplier to confirm receipt in writing. Clear references on both sides end most 'we didn't receive it' disputes before they start.
Why business payments get disputed
Most disputes between businesses are not fraud. They come from mismatches:
- One transfer covers several invoices, and the supplier cannot tell which ones.
- Withholding tax is deducted, so the amount received is less than the invoice.
- The supplier's finance team sees a credit but the sales team says the account is still owing.
- A payment is sent to an old account after the supplier changed banks.
- Partial payments are made without a note of what they cover.
Each of these can be fixed with better paperwork at the point of payment. The cost of not fixing them is real: delayed supplies, strained relationships, staff time spent searching old statements, and sometimes paying twice because nobody can prove the first payment went through. For a business with dozens of suppliers, a small amount of discipline each time money goes out saves a great deal of work later.
It also matters for audit and tax. An auditor or tax officer reviewing your expenses will want to see that each payment matches an invoice and that withholding tax was handled correctly. The same remittance records that settle a supplier query answer those questions too.
What a remittance advice should contain
- Payer
- Your company name and contact
- Payee
- Supplier name and the account paid
- Invoices covered
- Invoice numbers and amounts, one line each
- Deductions
- Withholding tax or other deductions, with amounts
- Net amount paid
- The sum actually transferred
- Date and reference
- Transfer date and the reference on the transaction
Send it the same day as the payment, to the supplier's accounts contact, with the transaction receipt attached. If you deducted withholding tax, see withholding tax on invoices for the credit note side.
Guarding against payment redirection fraud
A common fraud against Nigerian businesses is the fake change-of-account message. An email, apparently from a supplier, says their bank details have changed. The next payment goes to the fraudster.
- Never change a supplier's account details based on an email or message alone.
- Call the supplier on a number you already hold, not one in the new message.
- Require two people to approve any change to supplier details.
- Make a small test payment and confirm it before sending the full amount.
- Record who approved each change and when, so any later query can be traced.
Worked example: a contractor says the invoice is unpaid
Example figures only. Adebayo Logistics pays three invoices from a haulage contractor in one transfer:
| Invoice | Amount | Withholding tax deducted | Net |
|---|---|---|---|
| INV-301 | ₦1,200,000 | ₦60,000 | ₦1,140,000 |
| INV-307 | ₦850,000 | ₦42,500 | ₦807,500 |
| INV-312 | ₦640,000 | ₦32,000 | ₦608,000 |
| Total | ₦2,690,000 | ₦134,500 | ₦2,555,500 |
The withholding amounts here are illustrative; apply the rate that applies to your transaction. A month later the contractor says INV-307 is still unpaid. Adebayo's finance team sends the remittance advice, the transaction receipt for ₦2,555,500 and the withholding tax schedule. The contractor's bookkeeper had matched the payment only against INV-301 and INV-312. The account is corrected within the day.
When you are the supplier
The same discipline protects you when customers pay you. Issue numbered invoices, ask customers to quote the invoice number in their transfer, and send a receipt for every payment you receive. If a customer says they paid and you cannot find it, ask for their transaction receipt and reference, then search your account by amount and date. A shared, consistent reference system on both sides is what makes this quick. Tools such as invoicing and virtual accounts help by linking each payment to its invoice.
When a dispute does reach a formal stage, the business with the better records usually prevails. Courts and mediators look for documents made at the time of payment, not reconstructions made after an argument started.
Building the habit
- Use the invoice number as the payment reference where your bank allows it.
- Keep a single record linking each invoice to its payment and receipt.
- Ask suppliers to send a monthly statement of account and reconcile it.
- Store receipts so anyone on the finance team can find them quickly.
- Agree payment terms in writing, including what happens with part-payments.
- Review supplier balances with the supplier every quarter, not only when something goes wrong.

Where Pryme fits
A business paying from a Pryme Business Account can generate a regular or a verifiable receipt for each payment. Through the VerifyDoc.ai partnership, the supplier can check a verifiable receipt is genuine and unaltered, which removes doubt about a doctored payment record. For many payees at once, bulk payouts keep each transfer recorded. The Finance agent can prepare remittance advices and reconciliations; a person approves anything above a set ceiling, and actions are recorded.
