5 Early Warning Signs of a Cash Crunch — Before the P&L Tells You

Businesses don’t fail because they stop being profitable. They fail because they run out of cash. These are not the same thing: your P&L can say “we made money this month” while the bank account is empty — because profit is accrual and cash is collection. The gap between them is where most owners look only on the day a payment is due.

I spent years in manufacturing working on budgets, cash-flow planning and inventory — including through high-inflation periods, where keeping cash alive is a discipline of its own. What I learned: a crunch never happens in a day. It signals months ahead. Here are the five signals.

1. Receivables are ageing and you haven’t noticed

The earliest and most reliable indicator: average collection period. If it was 45 days last year and it’s 60 now, don’t let flat revenue reassure you — it means you’re tying up more cash to do the same business.

Practical check: age your receivables into 0-30 / 31-60 / 61-90 / 90+ days. If the 90+ bucket is growing, there’s frozen money there — and it rarely thaws at the same speed.

2. Inventory grows while sales stay flat

Inventory is money that hasn’t turned back into cash. If revenue is stable but inventory turnover is falling, you’re burying cash in the warehouse. In demand-forecasting and inventory-optimisation work I ran, a single business saved roughly $300,000 a year — and most of that came not from buying less, but from buying at the right time.

3. The payment-terms gap flips against you

Simple but lethal: if you collect from customers slower than you pay suppliers, you are financing the difference. Collect in 60, pay in 30, and every sale puts you 30 days in the hole. The bigger you grow, the wider that gap gets — which is why growth itself can cause a cash crunch.

4. “Invisible” fixed costs pile up

These slip through because each one is small: vehicle insurance, service contracts, software subscriptions, rent and dues, inspections and taxes. None of them breaks the budget alone; together they spike your cash calendar.

They share one trait: each is tied to an asset and has a known date. Which means they’re foreseeable — if you have an asset inventory. I laid out that skeleton in does your business have an asset inventory.

5. Decisions get made by looking at the bank balance

This is the most dangerous one. If investment, purchasing and payment decisions are driven by today’s balance rather than a cash projection, the business is driving without visibility. Even a simple 13-week cash-flow view ends that blindness.

What to do: three moves

1. Build a 13-week cash projection. No complex model needed: weekly collections, payments, closing balance. Update it every Friday.
2. Age your receivables and chase the oldest. Collection discipline creates cash faster than a sales increase does.
3. Tie fixed costs to assets and put them on a calendar. Insurance, maintenance, contract renewals — which asset, which date. Odovo does this for a vehicle fleet, Duevo for customer equipment and service contracts, RentMind for rental property, with reminders before the money is due.

Cash management isn’t about heroics; it’s about visibility. The fewer surprises you have, the more options you keep.

Frequently Asked Questions

I’m profitable — why do I have no cash? Because profit is booked on accrual: you record it when you invoice, you get paid 60 days later. In between, inventory, receivables and fixed costs consume cash. Profit tells you what you earned; cash tells you when.

Why 13 weeks specifically? It covers a quarter — long enough to show near-term obligations and seasonal swings, short enough that the forecast is still reliable. It’s the standard horizon in short-term liquidity management.

In a crunch, which cost do I cut first? General rule: first speed up collections (fastest impact), then slow inventory purchasing, and cut fixed costs last. Starting with fixed costs usually reduces capacity — which reduces revenue and deepens the crunch.
