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
Payments an AI agent prepares should be released by a person, with the level of approval set by risk: a ceiling per payment and per day above which a named person approves, and a short list of payments that always need a person whatever the amount, such as a new payee, changed bank details, an international payment or anything outside the usual pattern. International payments matter most, because UK Confirmation of Payee and the APP scam reimbursement rules do not cover them.
Agents that prepare payments save real time: they assemble the supplier run, attach invoices, check balances and draft the payment file. The control question is simple to ask and harder to answer well: which of those payments can go with a light check, and which need someone to stop and look? This article gives a structure for deciding.
Why payments to Nigeria need tighter rules
For UK domestic payments, two safety nets exist. Pay.UK's Confirmation of Payee checks the payee name for CHAPS, Faster Payments and Bacs payments; Nationwide's summary of the Payment Systems Regulator's APP scam reimbursement rules says they cover UK payments by Faster Payments or CHAPS. Pay.UK says international payments are not in scope of Confirmation of Payee, and the reimbursement rules exclude international payments. A payment from a UK account to Nigeria that goes to the wrong account is your loss unless the bank can recover it. Your approval rules are the safety net.
Three tiers of approval
The figures below are examples to adapt, not recommendations; set your own with your accountant and insurer.
| Tier | Example rule | Who approves |
|---|---|---|
| 1. Routine | Known payee, unchanged details, amount within 10% of the usual, under £2,000 or ₦3m | One person, in a batch |
| 2. Elevated | Above the tier 1 ceiling, or a daily total above £10,000 | One senior person reviewing each payment |
| 3. Always a person, plus a check | New payee, changed bank details, first payment to a country, urgent requests, anything the agent marks unusual | A senior person after an out-of-band confirmation, such as a call to a known number |
Tier 3 does not depend on amount. Fraud often starts small: a test payment to a new account, then the large one.
Setting the ceilings
Start from your own payment history rather than a round number. Pull the last 12 months of payments and look at three things: the typical size of a routine supplier payment, the largest regular payments (payroll, rent, main suppliers), and the total on a normal payment day. A tier 1 ceiling just above the typical routine payment catches the unusual ones without burying the approver. Review the ceilings every quarter and whenever the business changes, such as a new Lagos office or a large contract.
Check what your banks support, too. GTBank's GAPS service for Nigerian businesses, for example, has reviewer and approver roles: either can decline a payment schedule, the approver can cancel a pending batch, and processed batches cannot be cancelled. That last point is the reason approval has to happen before release, not after. Ask your UK bank how its business online banking handles approval rules for international payments.
What the agent should show the approver
- Payee legal name and registration number, and the account name returned for naira payments.
- The invoice and purchase order, with any differences highlighted.
- When the payee's bank details last changed, and who changed them.
- Payment history for this payee: typical amount and frequency.
- Currency, rate and fee, if a conversion is involved.
- Why the agent placed it in this tier.
An approver who sees only "14 payments, £18,420, approve?" is not controlling anything. The approval screen is the control.
Rules the agent itself must follow
- Never change payee bank details; it can only propose a change for a person to confirm.
- Never split a payment to get under a ceiling, and flag any series of payments that looks split.
- Never release a payment it prepared; release is a separate, human action.
- Record every draft, change and approval with the person and time.
Worked example
Example only. An agent prepares a Friday run of 12 supplier payments: 10 to known Nigerian suppliers in naira, each under ₦3m, one of ₦9.5m to a regular supplier, and one to a new freelancer in Abuja. The ten go in a tier 1 batch for one approver. The ₦9.5m payment is tier 2, reviewed individually. The new freelancer is tier 3: the approver calls the freelancer on the number in their signed contract, confirms the account, and only then approves.
Review the control itself every quarter: sample a few approved payments, check the approver saw the invoice and the payee history, and look at how many tier 3 payments were confirmed by call. A rule that is always followed in name but never in substance is worse than no rule, because it gives false comfort.
For the people side of these controls, see segregation of duties in a small UK and Nigeria team and dual authorisation on business payments to Nigeria.
Where Pryme fits
Pryme Business Accounts come with a Chief of Staff and Finance agent, built by Pryme Intelligence. They prepare work; a person approves above a ceiling you set, and actions are recorded. Security uses an authenticator app rather than SMS codes and a transaction PIN (security).
Questions people ask
Should an AI agent be allowed to send payments on its own?
Preparing, yes; releasing, no. Keep release as a separate human step with ceilings set by risk.
What approval limit should a small business set?
There is no standard figure. Set ceilings by payment and by day that match your normal pattern, and agree them with your accountant.
Which payments always need a person?
New payees, changed bank details, first payments to a country, urgent requests and anything outside the usual pattern, whatever the amount.
Does Confirmation of Payee protect payments to Nigeria?
No. Pay.UK says international payments are not in scope.
