Yes — a business can show a profit on its books and still miss payroll, because profit recognizes revenue when earned while cash only counts when collected. A U.S. Bank study widely cited in industry reporting attributed cash-flow problems to 82% of small-business failures; whatever the exact number, the mechanism is documented and predictable: inventory bought ahead of sales, invoices paid at 30 to 60 days, and loan payments that fall due regardless. The fix is timing, not profitability.
Business News 7 publishes information, not financial advice; the numbers and structures below are explanations, and your accountant should adapt them to your books.
What is the cash conversion cycle?
The cash conversion cycle measures the days between paying for inventory and collecting from customers — and every day in it is a day your money is working for someone else. A retailer that buys stock on 15-day supplier terms and sells through over 45 days while customers pay by card has a short cycle. A wholesaler that carries 60 days of inventory and invoices on net-45 terms has a long one, and needs cash reserves to bridge roughly three months of operating costs. The formula is inventory days plus receivable days minus payable days, standard in any accounting text.
Which habits close the gap?
Four, and none require an MBA:
- Invoice the same day the work ships, not month-end — every day of delay is a day of free credit you extend.
- Track receivables weekly by age; a 13-week rolling cash forecast is the format most lenders and the SBA's own training materials recommend.
- Match big inventory buys to sales pace, not supplier discounts alone — a volume discount financed by a cash crunch is a loss wearing a discount's clothes.
- Keep a separate tax reserve account; the IRS estimate tax calendar does not care about your receivables.
How do growth spurts make it worse?
Growth consumes cash before it produces any, which is the counterintuitive part owners learn late. Doubling orders means doubling inventory and labor costs now while the extra revenue lands a cycle later; the faster the growth, the deeper the bridge needs to be. This is why businesses that survived years at steady scale fail in their best year — the wall is arithmetic, not demand.
When does outside financing make sense?
Financing a structural cash gap with a revolving line of credit is ordinary practice; financing a permanent loss with debt is not. The test is whether the gap is temporary and self-closing — a seasonal bridge, a large confirmed order — because interest on a loan against uncollected invoices is survivable, and interest compounding on negative unit economics is not.
What should an owner actually watch weekly?
Cash on hand against the 13-week forecast, receivables over 60 days, and the next four fixed payments. That trio predicts most cash crises weeks ahead, which is enough time to act — arranging a line of credit, chasing late invoices, or negotiating terms with suppliers is possible in three weeks and impossible in three days.
What the evidence establishes is that cash timing, not profitability, decides most short-run survivals. What it cannot establish is any single business's bridge length — that is one forecast no one else can run for you.
