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 approval limits in tiers: staff spend small amounts on their own within a budget, a manager approves the middle band, and anything above a ceiling, or anything unusual such as a new supplier or changed bank details, comes to you. Write the limits into a short policy, mirror them in the bank mandate and payment tools, and review them every quarter.
When you live abroad, every payment that needs you becomes a delay, and every payment that does not need you becomes a risk. Approval limits are how you choose where that line sits. Done well, your office in Lagos or Abuja keeps moving while you sleep, and you only see the payments that deserve your attention.
Start with what actually gets spent
Before setting any number, pull three months of payments and sort them into groups. In most small Nigerian businesses they fall into the same handful:
- Recurring fixed costs: rent, salaries, diesel, internet, security.
- Regular variable costs: stock, supplier invoices, transport, data and airtime.
- Small day-to-day items: cleaning, repairs, office supplies, courier fees.
- One-off or unusual items: equipment, new suppliers, advances to staff, refunds to customers.
The point is to see where the volume is. If 80 payments a month are under ₦50,000 and four are over ₦1 million, your limits should let the 80 flow and stop the four.
A tiered limit structure
The amounts below are examples only for a business spending roughly ₦15 million a month. Scale them to your own figures.
| Tier | Example limit | Who can approve | Condition |
|---|---|---|---|
| 1. Staff spend | Up to ₦50,000 per item | Staff member, within a monthly budget | Receipt uploaded within 48 hours |
| 2. Manager | ₦50,001 to ₦500,000 | Office or operations manager | Existing supplier, budget line exists |
| 3. Owner or director | Above ₦500,000 | You or a second director | Supporting invoice and reason |
| Always escalate | Any amount | You | New supplier, changed bank details, payment to a staff member's own account, refunds, anything outside budget |
The "always escalate" row matters more than the numbers. Fraud and costly mistakes rarely look like large payments; they look like a normal supplier with a new account number, or a refund to a customer nobody can name.
Make the bank mandate match the policy
A written policy that the bank does not enforce is a suggestion. Nigerian banks take a mandate for each corporate account that sets who can sign and how: Greenwich Merchant Bank's corporate form, for example, offers sole, either, both or other signing options, set by a board resolution. Practical steps:
- Keep the operating account for tier 1 and tier 2 spending, with a balance topped up to a budget.
- Hold reserves in a separate account that needs your approval, or two signatures.
- Set the online banking roles so the manager can create payments but only you can release payments above the tier 2 ceiling.
- When a manager leaves, change the mandate the same week. See changing bank signatories when your manager leaves and bank mandates with signatories abroad.
Escalation that works across time zones
Nigeria runs on West Africa Time. From the UK you are at most an hour apart; from Toronto or Houston you are five or more hours behind, so your morning is the Lagos afternoon. Escalation should have a rule for when you do not answer:
- Set a response window, for example four working hours, after which a named second approver (a co-director or trusted accountant) can decide.
- Define urgent: payroll on the due date, a tax payment, a supplier who will stop delivery. Urgent items go to both approvers at once.
- Never treat a phone call or WhatsApp voice note as approval for a change of bank details. The FBI's guidance on business email compromise advises checking account-change requests through a second channel; the same applies to messages that look like they come from you.
For the scheduling side, see approvals across time zones with a team in Nigeria.
Keeping limits honest over time
- Watch for splitting: three ₦480,000 payments to the same supplier on one day are a ₦1.44 million payment. Report on payments just under each ceiling.
- Review limits every quarter against inflation and volume. A limit that forces you to approve every diesel purchase will be worked around.
- Compare spending to budget monthly, not just to limits. A manager can stay under every ceiling and still overspend.
- Keep cash separate: CBN rules effective 1 January 2026 cap corporate cash withdrawals at ₦5 million a week across channels, with a 5% charge on the excess, as reported by Channels TV. Cash spending needs its own float and log.
Write it on one page
The policy your staff will follow is the one they can read in two minutes. One page is enough: the tiers and amounts, the "always escalate" list, who the second approver is when you cannot be reached, what evidence each payment needs, and the date of the next review. Ask each person with a spending role to confirm they have read it, and keep that confirmation with the board resolution that set the bank mandate. When a limit changes, change the page, the bank roles and the payment tool on the same day, so the three never disagree.
Where Pryme fits
Pryme Business Accounts come with a Chief of Staff and a Finance agent, built by Pryme Intelligence. They prepare payments and supporting papers; a person approves anything above a ceiling you set, and every action is recorded, which is the tier structure above built into the tool. Approvals are secured with an authenticator app and a transaction PIN rather than SMS codes (security).
Questions people ask
What is a sensible approval limit for a Nigerian office manager?
There is no standard figure. Look at three months of payments and set the manager's ceiling so most routine payments flow, while the few large or unusual ones come to you.
Should a new supplier always need the owner's approval?
Yes. New suppliers and changed bank details are the most common route for fraud, so they should escalate whatever the amount.
How do I stop staff splitting payments to stay under the limit?
Report on payments just under each ceiling and on several payments to the same payee in a day, and treat them as one payment for approval.
Can I approve payments from abroad on my phone?
Yes, if the bank or payment tool gives you a release role. Use an authenticator app rather than SMS where possible, and never approve bank detail changes from a message alone.
