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
A cross-border audit trail needs the same chain on both sides: a contract or invoice, proof of payment, a receipt and a bank statement that match. The CRA expects records kept for six years from the end of the last tax year they relate to, and Nigeria's Tax Administration Act 2025 sets a minimum of six years too. A verifiable receipt is one that anyone you give it to can check is genuine and unaltered, which saves you proving it by other means when a Nigerian document is questioned.
Why Nigerian receipts get questioned
An auditor in Calgary looking at a ₦2,400,000 payment to a Lagos supplier has three questions: did the payment happen, what was it for, and is this paper what it says it is. A screenshot of a bank app, a scanned receipt with a handwritten amount or a PDF that could have been edited answers the first question badly and the third not at all.
The problem is not that Nigerian suppliers are less careful. It is that the reviewer cannot easily phone the bank or the supplier, the documents are in another currency, and a PDF is easy to alter. Each extra step the reviewer must take adds time and doubt.
What each tax authority expects
| Canada (CRA) | Nigeria (NTAA 2025 s.31) | |
|---|---|---|
| How long | Six years from the end of the last tax year the records relate to | Not less than six years after the year of assessment |
| Where | At your place of business or residence in Canada, unless the CRA gives written permission | Not stated in the summary we read |
| Language | Not stated on the page | English, with certified translation on demand |
| What | Records that support income and expenses | Sufficient information on all relevant transactions to determine tax liability |
One CRA point catches cross-border businesses: its records page says that records kept outside Canada and merely accessed electronically from Canada are not records kept in Canada. If your Nigerian team holds the originals on a Lagos server, keep a copy under your control in Canada.
The chain that makes a payment auditable
- Agreement: a contract, purchase order or quote showing what was bought and the price.
- Invoice: from the supplier, with their name, address, tax ID where they have one, date, amount and currency.
- Payment: your bank or account record showing the amount, date, payee and reference.
- Receipt: confirming the supplier received the money.
- Conversion: if you converted CAD to naira, the rate and fee for that conversion.
- Ledger entry: the CAD amount in your books, using your stated exchange-rate policy.
Every link should carry a common reference, such as the invoice number, so a reviewer can follow the chain without asking you.
What makes a receipt verifiable
A regular receipt is a statement: "this was paid". A verifiable receipt adds a way for the person holding it to check, independently, that it was issued by the source it claims and has not been changed since. The value is that you no longer have to prove authenticity yourself; the reviewer checks it.
- It identifies the issuer and the transaction clearly.
- It can be checked by anyone you share it with, without logging into your account.
- Any change to the document after issue shows up when it is checked.
- It is stored with the rest of the chain, not in a chat thread.
Worked example
Example only. A Canadian company pays a Lagos design studio ₦1,500,000 for brand work, after converting CAD 1,250 at an invented rate of ₦1,200. The file holds the signed quote, the studio's invoice INV-114, the payment record referencing INV-114, a verifiable receipt for the payment, and the conversion record. The ledger shows CAD 1,250 as a marketing expense. At review, the auditor checks the receipt, matches the reference and moves on.
When the CRA or a Nigerian tax office asks
Reviews rarely ask for everything at once. A CRA reviewer typically picks a sample of large or unusual expenses and asks for support. A Nigerian tax office reviewing your subsidiary may ask for the other side: evidence that money received from Canada was what the contract said. A file built on the chain above answers both from the same documents, which is the point of keeping one set rather than two.
Respond with the full chain for each item, not just the receipt. If a link is missing, say so and give the next best evidence, such as an email from the supplier confirming receipt, rather than producing a new document after the event.
Practical rules for your team
- Never pay without an invoice reference in the payment narration.
- Save documents as PDFs in a shared folder named by year, month and supplier.
- Ask Nigerian suppliers for receipts in English on letterhead; if a document is in another language, get a translation.
- Record the exchange rate on the day you pay and keep the source.
- Reconcile monthly; gaps are easier to fix within weeks than at year end.
