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 rules before the trip: either reimburse actual costs against naira receipts, or pay a fixed daily allowance (per diem), and state which exchange rate converts naira to cedis. Keep every receipt or allowance record for at least six years, the Revenue Administration Act minimum, and confirm with GRA or a tax adviser how a per diem is treated for PAYE, because we could not confirm GRA's rule on an official page.
Two ways to pay for a business trip
| Method | How it works | Evidence needed | Tax question to check |
|---|---|---|---|
| Actual costs | Staff pay, then claim each cost back | A receipt for each item | Usually reimbursement of business costs, but confirm |
| Per diem | A fixed daily amount for meals and incidentals | Trip dates, purpose, approval | Whether any part is a taxable allowance for PAYE |
| Company pays directly | Hotel and flights booked and paid by the company | Supplier invoices in the company's name | Fewest staff claims to check |
Many firms mix them: the company books flights and the hotel, and staff get a per diem for meals and local transport. Whatever you choose, write it in a short travel policy so every trip is handled the same way.
Getting receipts in Lagos
Hotels, airlines and larger restaurants in Lagos issue printed or emailed receipts. Ride-hailing apps email trip receipts. Smaller vendors, street food, market purchases and many keke or bus fares do not. Plan for that:
- Ask staff to request a receipt every time, even a handwritten one with the vendor's name, date and amount.
- Accept transfer screenshots only with a note of what was bought; a transfer proves money moved, not what it paid for. See the Ledger on whether a transfer receipt is proof of payment.
- For costs with no receipt, use a signed missing-receipt form with a cap per trip.
- Photograph thermal-paper receipts at once, because they fade.
Converting naira claims into cedis
Decide one rule and print it on the claim form. Common choices are the rate on the day the cost was paid, the rate on the day staff changed cedis into naira (using the bureau receipt), or an average rate for the trip. IAS 21 allows an average rate for a week or month for recording transactions if rates do not fluctuate significantly, which suits a short trip, but agree it with your accountant.
Worked example
Illustrative figures only, at an example rate of GH₵1 = ₦120.
| Item | Naira | Cedis |
|---|---|---|
| Hotel, 3 nights at ₦90,000 | ₦270,000 | GH₵2,250 |
| Ride-hailing, airport and meetings | ₦48,000 | GH₵400 |
| Meals with receipts | ₦66,000 | GH₵550 |
| Total claim | ₦384,000 | GH₵3,200 |
Check: 270,000 plus 48,000 plus 66,000 is ₦384,000, and 384,000 / 120 is GH₵3,200. Attach the receipts in naira and show the rate on the form.
The tax side in Ghana
Whether a per diem is a tax-free reimbursement or a taxable allowance depends on Ghana's income tax rules and on whether the amount is reasonable for the costs it covers. We could not open a GRA page setting out the current treatment for this article, so ask GRA or a chartered tax adviser before you set a flat rate. Reimbursing actual business costs against receipts is generally easier to defend because the evidence shows what the money paid for.
Keep the records. PwC's Ghana tax administration summary (reviewed March 2026) says records of receipts, payments, revenue, expenditure, assets and liabilities must be kept for at least six years under the Revenue Administration Act, 2016 (Act 915), and that GRA can access records during an audit.
Advances, floats and cash
Staff often need naira before they land. Three common approaches each leave a different trail. A cash advance in cedis that the employee changes at a bureau should come back with the bureau receipt, which also fixes the exchange rate for the claim. A naira float sent by the company to the employee's Nigerian account or wallet appears on the company's statement, and the employee accounts for it on return. A company card avoids advances but needs the card statement matched to receipts.
Whichever you use, settle the advance on the claim form: total costs minus advance equals the amount owed to or by the employee. If the trip cost ₦384,000 and the float was ₦400,000, the employee returns ₦16,000 or it is deducted from the next claim. Set a deadline, such as ten working days after return, for claims and unused floats.
What the claim form should hold
- Employee name, trip dates and destination.
- Business purpose and the manager who approved the trip.
- Each cost with date, vendor, naira amount and receipt number.
- Exchange rate used and its source.
- Per diem days and rate, if used.
- Approver's signature and payment date.
For receipts your firm issues to Nigerian clients during the trip, see verifiable receipts for Nigerian customers. For trip planning costs, see budgeting an Accra to Lagos trip.
Where Pryme fits
A Pryme Business Account holds naira, so the company can pay a Lagos hotel or send staff a naira float before they travel, with each payment on the statement. The Finance agent can check claims against receipts and policy and prepare them for approval; a person approves above a set ceiling. Receipts can be issued as regular or verifiable through VerifyDoc.ai.
Questions people ask
Is a per diem taxable in Ghana?
It depends on GRA's rules and whether the amount is reasonable. We could not confirm the current treatment on a GRA page; ask GRA or a tax adviser.
What if a Lagos vendor does not give a receipt?
Use a signed missing-receipt form with a cap, and ask for at least a handwritten note with vendor, date and amount.
Which exchange rate should staff use for naira expenses?
One rule set by the company: the rate on the day of payment, the bureau rate on the exchange receipt, or a trip average agreed with your accountant.
How long do I keep staff expense receipts?
At least six years under Ghana's Revenue Administration Act, 2016.
