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
Each method fails differently: transfers can be faked with a false alert, POS payments can be disputed and reversed, and cash can be counterfeit or stolen. The safest mix for most stalls is transfer as the default, confirmed in your own banking app before goods leave, POS for card-paying customers with a receipt kept for every sale, and cash for small sums checked note by note.
A busy stall can take dozens of payments an hour, in three different forms, while you are also measuring, wrapping and bargaining. Each payment method has a weak point, and fraudsters choose the one you check least. This guide sets out the risks of each, what Nigerian rules say, and a short rule set you can apply without slowing down.
The three methods side by side
| Bank transfer | POS (card) | Cash | |
|---|---|---|---|
| Main risk | Fake alert or fake receipt; reversal of a mistaken transfer | Customer disputes the charge; failed transaction that looks successful | Counterfeit notes; theft; miscounting |
| When you know you are paid | When the credit shows in your own app | When the terminal prints approved and the settlement reaches your account | At once, if the notes are real |
| Cost | Usually low or none to receive | Terminal charges set by your provider | Time to count and bank; safety |
| Evidence | Bank record on both sides | Terminal receipt and transaction reference | None unless you write it down |
Transfer: the risks and how to close them
The common trick is showing a screenshot or sending a fake SMS. The money has not arrived; the customer leaves with the goods. The defence is simple and absolute: only your own banking app counts. Not the customer's phone, not an SMS, not a forwarded receipt. See how to spot a fake credit alert.
A second risk is a reversal: someone claims they sent money to you by mistake. Do not refund to a different account than the one it came from; see mistaken transfer scams.
POS: the risks and how to close them
Card payments can be disputed. CBN's 2020 circular on chargeback periods, as summarised by Mondaq, set short windows: POS disputes between merchant and cardholder to be resolved within 48 hours, and failed POS refunds within 48 hours. If a customer disputes a sale, your proof is the terminal receipt and transaction reference.
If you use a POS terminal as an agent rather than a merchant, CBN's agent banking guidelines of October 2025 add rules: a receipt for every transaction, geo-tagged devices, and customer cash-out limits of ₦100,000 a day and ₦500,000 a week (Techpoint Africa). See POS fraud for card swaps and fake terminals.
Cash: the risks and how to close them
Cash settles at once but carries counterfeit and theft risk. The CBN's security features include raised print, an embossed portrait, a security thread with 'CBN' lettering that becomes continuous against light, and a watermark on the ₦100 to ₦1,000 notes. Feel every note and hold larger ones to light. Cash also needs banking: since 1 January 2026, individuals can withdraw up to ₦500,000 a week across all channels, with a 3% charge above that (Channels TV), which affects how much change you can easily keep.
Choosing your mix
The right balance depends on what you sell and who buys. A stall selling small items to passing customers will always take cash, so the priority is fast note checking and frequent banking. A trader selling higher-value goods, such as fabric, electronics or building materials, gains most from pushing customers to transfer, because one fake alert on a large sale costs more than a day of small cash risks. If many customers pay by card, a POS terminal adds sales, but only if you keep the receipts and watch settlements. Whatever the mix, decide your rules once and apply them to every customer, including regulars, so that nobody feels singled out.
A practical rule set
- Transfer is the default for anything above small change. Show your account details on a printed card so customers do not mistype.
- No goods leave before the credit is in your app. If the network is slow, the customer waits or pays another way.
- For POS, keep every receipt for at least as long as a customer could dispute it, filed by day.
- Cash for small sums, every note felt; larger notes held to light.
- Bank cash daily and do not keep the day's takings at the stall.
- Reconcile at closing: compare transfers in your app, POS settlements and counted cash against your sales list. See the end-of-day cash-up.
Worked example
Example: a fabric seller takes ₦180,000 in a day: ₦120,000 by transfer, ₦40,000 by POS and ₦20,000 in cash. At closing, the app shows ₦110,000 in transfers. Checking the sales list against the app, one ₦10,000 sale has no matching credit; the customer showed a screenshot. Under the rules above, that sale would have waited until the credit appeared. The day's real takings were ₦170,000, and the ₦10,000 is a lesson.

A cardholder can dispute a charge. CBN's 2020 circular set short resolution windows, and your terminal receipt is your evidence.
How do I know a transfer is real?
Only trust the credit in your own banking app, not a screenshot, SMS or the customer's phone.
How much cash can a POS agent pay out per customer?
CBN's October 2025 agent banking guidelines set customer cash-out limits of ₦100,000 a day and ₦500,000 a week, as reported by Techpoint Africa.
