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
Keep only the opening float you need for the next morning, set from your own sales records, and bank or transfer the rest of the day's takings the same day. A common method is to hold enough small notes for the first few hours of change and early purchases, lock it away, and treat everything above it as money that should leave the shop before closing.
Why overnight cash is the problem
Cash in a shop at night is exposed to burglary, fire and staff theft with nobody there to notice. It is also often uninsured. Money insurance, where you have it, usually covers cash in a locked safe against burglary or housebreaking, not cash in a drawer or a bag under the counter; the Nigerian Agricultural Insurance Corporation's money insurance proposal form, for example, offers cover for money other than wages "in a locked safe or strongroom" against burglary and housebreaking only. So the question is not just how much you can afford to lose, but how much you can lose with no cover at all.
The float method
A float is the cash you start the day with. It exists so you can give change and pay small early costs before sales start coming in. Everything else is takings. Set your float like this:
- Look at a normal week. Note how much change you give in the first two or three hours, and any cash you must pay out early (a supplier, transport, a casual worker).
- Add a margin for a busier-than-usual morning, perhaps a quarter more.
- Hold it in small notes. A float of ₦1,000 notes cannot give change for a ₦1,200 sale.
- Write the float figure down and count it in at opening and out at closing.
- Everything above the float is takings that should be banked, transferred or taken home safely before night.
Worked example
Example only. A provisions shop takes about ₦180,000 a day, two thirds by transfer and one third in cash, so about ₦60,000 in cash. In the first three hours the owner gives about ₦12,000 in change and pays a ₦6,000 delivery charge in cash. Float: ₦12,000 + ₦6,000 = ₦18,000, plus a quarter for a busy morning (₦4,500) = ₦22,500, rounded to ₦25,000 in small notes. At closing she has ₦85,000 in cash: the ₦25,000 float plus ₦60,000 takings. She keeps ₦25,000 locked away and deposits ₦60,000 before closing time. If the shop were burgled, the most at risk would be ₦25,000, not ₦85,000.
The case for same-day deposit
- Less to steal. Burglars and robbers gain little from a shop known to bank daily.
- Fewer questions. Banked takings create a record of your sales, useful for loans, tax and disputes.
- Less temptation. Staff theft is easier to spot when cash in hand should always equal the float.
- No withdrawal limits on deposits. CBN cash limits apply to withdrawals; a CBN circular of December 2025 set a weekly cash-withdrawal limit of ₦500,000 for individuals and ₦5 million for corporates, with fees above that. Depositing during the week and drawing a modest float is easier to manage than hoarding cash.
Same-day banking has its own risk: carrying cash on the road. Vary your route and time, avoid announcing it, and use a nearby agent, a cash deposit machine or a branch during busy hours. Our guide to taking daily sales to the bank safely covers this.
If you must keep more overnight
Some traders close after banking hours or a long way from a bank. If you must hold takings overnight:
- Use a proper safe that is fixed to the floor or wall, and keep the keys off the premises. Insurers ask about both.
- Split cash: float in one place, takings in the safe.
- Do not keep cash in the same place every night, and do not tell staff or neighbours where it is.
- Move it out at opening the next morning, before the shop gets busy.
- Consider whether some customers could pay by transfer instead, which reduces cash in the first place.
Reviewing the float
Your float is not fixed for ever. Review it monthly, and before busy periods such as festive seasons or school resumption, when more customers pay in cash and change runs out faster. If you often run short of change by mid-morning, the float is too small or in the wrong notes. If the float sits untouched most days, it is larger than it needs to be, and the extra is simply cash at risk. Keep a short record of float, takings and deposits each day; it makes shortages easy to spot and helps if you ever make an insurance claim.
If several people handle cash, make one person responsible for counting the float in and out, and have a second person sign the count.
Where Pryme fits
Moving more sales to transfer reduces cash in the shop. A Pryme Business Account gives you account details customers can pay into, a bank-transfer checkout (free), and separate accounts to keep the float, takings and savings apart. Naira deposits are held by Solid Allianze Microfinance Bank, licensed by the CBN and insured by the NDIC up to the applicable limit.

Questions people ask
How much cash should I leave in my shop at night?
Only the float you need to open the next morning, worked out from your own change and early payments, with the rest banked or transferred the same day.
What is a cash float in a shop?
The fixed amount of cash, in small notes, that a shop starts each day with to give change and pay small early costs. It is counted in and out daily.
Is cash kept in my shop covered by insurance?
Usually only if you have money insurance and keep it in a locked safe. Proposal forms such as NAIC's cover money in a safe against burglary and housebreaking, not cash left in a drawer.
Is there a limit on how much cash I can deposit in Nigeria?
The CBN limits weekly cash withdrawals, not deposits. Check with your bank for any cash-handling charges on large deposits.
