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
The cash conversion cycle measures how many days pass between paying for stock and collecting cash from the customer who bought it. It is days of inventory (DIO) plus days customers take to pay (DSO) minus days you take to pay suppliers (DPO). The longer the cycle, the more cash a profitable business needs just to keep trading.
Profitable and still broke
A trader buys goods, sells them at a markup and records a profit. But the profit is only on paper until the customer pays. In the meantime the trader has already paid the supplier and is buying the next batch. If sales grow, the gap grows with them. That is why businesses with healthy margins still borrow to pay salaries: their cash is sitting in stock on the shelf and in invoices customers have not settled.
The three parts
- DIO (days inventory outstanding)
- Average stock ÷ annual cost of goods sold × 365. How long goods sit before they are sold.
- DSO (days sales outstanding)
- Average money owed by customers ÷ annual sales × 365. How long customers take to pay.
- DPO (days payables outstanding)
- Average money owed to suppliers ÷ annual cost of goods sold × 365. How long you take to pay suppliers.
- Cash conversion cycle
- DIO + DSO − DPO
Use averages, for example opening plus closing balance divided by two, or better, the average of month-end figures. A single year-end figure can mislead if December stock is unusually high.
Where the figures come from
You need four numbers from your books: sales for the year, cost of goods sold, and average balances for stock, money owed by customers and money owed to suppliers. If you do not have them, that is itself a finding. Section 31 of the Nigeria Tax Administration Act 2025 already requires every business to keep records with enough information on all relevant transactions to determine its tax, for at least six years, so the underlying data should exist.
- Stock: from stock counts at month end, valued at cost. Your cost of goods sold calculation uses the same counts.
- Customers: from your debtors list or credit sales book.
- Suppliers: from unpaid supplier invoices.
- Sales and cost of goods sold: from your profit and loss account.
If you trade mostly in cash, DSO will be close to zero and the cycle is driven by stock. If you sell on credit to companies, DSO usually dominates.
Worked example: a building materials trader
Example only. A trader in Enugu has annual sales of ₦60,000,000 and cost of goods sold of ₦48,000,000, so gross profit is ₦12,000,000. Average figures over the year:
| Measure | Calculation | Days |
|---|---|---|
| Stock held: ₦6,000,000 | 6,000,000 ÷ 48,000,000 × 365 | 45.6 |
| Owed by customers: ₦4,000,000 | 4,000,000 ÷ 60,000,000 × 365 | 24.3 |
| Owed to suppliers: ₦2,000,000 | 2,000,000 ÷ 48,000,000 × 365 | 15.2 |
| Cash conversion cycle | 45.6 + 24.3 − 15.2 | 54.7 |
For about 55 days, each naira paid to a supplier is locked in the business before it comes back. The trader is profitable, yet the ₦6,000,000 of stock and ₦4,000,000 of receivables, less the ₦2,000,000 suppliers are effectively lending, means ₦8,000,000 of the owner's or lenders' money is tied up in trading at any time.
What a shorter cycle frees up
If the trader cut stock holding to 30 days of cost of goods sold, average stock would fall to ₦48,000,000 × 30 ÷ 365 ≈ ₦3,945,000. That releases about ₦2,055,000 in cash without selling a single extra bag, which could replace an expensive overdraft or fund a reserve.
Levers you control
Shorten DIO
- Reorder little and often for fast movers, if supply is reliable.
- Clear slow and dead stock instead of letting it sit; see what to do with dead stock.
- Count stock regularly so you know what is actually moving.
Shorten DSO
- Agree payment terms in writing before delivery.
- Send statements monthly from a clear credit sales book.
- Offer a small discount for payment on delivery if it costs less than waiting.
- Stop new credit to customers who are overdue.
Lengthen DPO, fairly
- Negotiate terms with suppliers once you have a payment record.
- Pay on the agreed date, not early, unless an early-payment discount is worth it.
- Do not stretch beyond agreed terms; losing a supplier's trust costs more than the days gained.
Why it matters more when prices rise
Inflation lengthens the pain of a long cycle. The National Bureau of Statistics put headline inflation at 14.63% year on year in September 2026 (Voice of Nigeria, 16 October 2026). When restocking costs more each time, every day of the cycle needs more naira to replace the same goods. A 55-day cycle in a rising market can turn a profitable year into a cash squeeze. A 13-week cash flow forecast shows when that squeeze lands.
Track the cycle each quarter. A rising number is an early warning, often before the bank balance shows it, and it points to which lever needs attention.
Where Pryme fits
Getting paid faster shortens DSO. Pryme's invoicing and bank-transfer checkout (free) let customers pay against a specific invoice, and the Finance agent can prepare reminders for a person to approve. See also chasing invoices well.
Questions people ask
What is the cash conversion cycle formula?
Days inventory outstanding plus days sales outstanding minus days payables outstanding (DIO + DSO − DPO).
Why is my business profitable but I have no cash?
Profit is counted when you sell; cash arrives when customers pay. Money tied up in stock and unpaid invoices, plus loan principal and drawings, can absorb all the profit.
What is a good cash conversion cycle?
There is no single figure. Compare yours over time and against similar businesses. A shorter cycle means less cash is needed to trade.
How can a small business reduce its cash conversion cycle?
Hold less slow-moving stock, collect from customers sooner, and agree fair longer terms with suppliers.
