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
Overtrading is when a business takes on more sales than its cash can support: it must pay for stock and costs before customers pay, so every extra naira of sales needs extra cash tied up in stock and debtors. The funding gap is roughly daily cost of sales multiplied by the working capital cycle (stock days plus debtor days minus creditor days), and it grows in line with sales.
Growth looks like the answer to every money problem, so it is surprising when a business with full order books cannot pay its suppliers. The reason is timing. Profit is earned when you sell; cash comes when the customer pays. In between, you have bought stock, paid staff and covered rent. The faster you grow, the more cash sits in that gap.
The working capital cycle
- Stock days
- How long goods sit before they sell: stock ÷ cost of sales × days.
- Debtor days
- How long customers take to pay: debtors ÷ sales × days.
- Creditor days
- How long you take to pay suppliers: creditors ÷ purchases × days.
- Cash cycle
- Stock days + debtor days − creditor days.
The longer the cycle, the more cash each naira of sales needs. See the cash conversion cycle and working capital explained.
The funding gap maths
Example only. A wholesaler sells ₦10,000,000 a month to retailers, with cost of sales at 75% (₦7,500,000 a month, or ₦250,000 a day on a 30-day month). Stock sits 45 days, retailers pay in 30 days, and suppliers are paid in 15 days. Cash cycle = 45 + 30 − 15 = 60 days.
| Now | After sales double | |
|---|---|---|
| Monthly sales | ₦10,000,000 | ₦20,000,000 |
| Daily cost of sales | ₦250,000 | ₦500,000 |
| Cash cycle | 60 days | 60 days |
| Working capital needed | ₦15,000,000 | ₦30,000,000 |
| Extra cash required | ₦15,000,000 | |
| Monthly gross profit | ₦2,500,000 | ₦5,000,000 |
Doubling sales needs ₦15 million more in stock and debtors. Even the higher gross profit of ₦5 million a month, before overheads, would take three months to fund that gap with nothing else spent. If growth is fast, the cash runs out first.
Cutting the cycle helps. If the same business got retailers to pay in 20 days and stock to turn in 35, the cycle becomes 35 + 20 − 15 = 40 days, and at doubled sales the need falls to ₦20,000,000 (₦500,000 × 40).
A short case
Example only. A uniform maker with ₦3 million a month of sales wins a contract to supply three schools: ₦12 million of uniforms, delivered in August, paid 60 days after delivery. Fabric and trimmings (₦7 million) must be paid upfront, and four extra tailors cost ₦1.2 million over two months. Between June and October the business needs ₦8.2 million it does not have, on top of its normal costs. The contract is profitable on paper, but without a deposit, an agreed facility or shorter payment terms it would leave the business unable to pay its regular suppliers and staff. Asking the schools for a 40% deposit (₦4.8 million) would cut the gap to ₦3.4 million.
Warning signs
- Sales and profit rising, but the bank balance falling or the overdraft always at its limit.
- Paying suppliers later each month, or being put on cash-only terms.
- Delaying salaries, tax or pension payments to cover stock.
- Taking larger orders with longer payment terms to win them.
- Stock-outs on best sellers because there is no cash to reorder.
- The owner spending most of the day moving money between accounts.
Inflation makes it worse
When supplier prices rise, the same volume of stock costs more naira, so the working capital gap widens even without growth. The NBS put headline inflation at 14.63% year on year for September 2026 (reported by Voice of Nigeria); check the latest monthly release. A business whose cost of sales rises by that percentage needs roughly that much more working capital to stand still.
Tax as you grow
Growth can also bring a tax bill that was not there before. PwC's Nigeria summary (reviewed May 2026) lists a 0% rate for small companies with thresholds of ₦100 million turnover and ₦250 million fixed assets, and gives the prevailing company income tax rate as 30%. Once a company passes the small company limits, profits become taxable at the rate set by law. Plan for that cash in your forecast; see small company tax under the Nigeria Tax Act 2025. This is information, not tax advice.
What to do: steps
- Calculate your cash cycle and funding gap at today's and planned sales.
- Build a 13-week cash forecast before accepting a large new order.
- Ask big new customers for a deposit or shorter terms, and invoice promptly.
- Negotiate longer supplier terms, using your payment record.
- Clear slow stock to release cash.
- Arrange funding before you need it: a lender offers a facility based on your figures, and you decide whether to accept the terms after seeing the full cost.
- Grow in steps you can fund, rather than taking every order.

Questions people ask
What is overtrading in business?
Taking on more sales than your cash can fund. Each sale ties up cash in stock and unpaid invoices until customers pay, so rapid growth can exhaust the bank balance.
How do I know if my business is overtrading?
Rising sales with a falling bank balance, paying suppliers later, stock-outs on best sellers and constant overdraft use are common signs.
How do I calculate my working capital need?
Multiply daily cost of sales by your cash cycle (stock days + debtor days − creditor days). ₦250,000 a day × 60 days needs ₦15m.
Can a profitable business run out of cash?
Yes. Profit is recorded when you sell, but cash arrives when customers pay. Fast growth widens that gap.
