Revenue growing strongly. Profit healthy. Cash getting tighter.

This is the working capital trap, and it kills more businesses than poor profitability ever will.

Why Profitable Businesses Run Out of Cash

Strong sales growth. Good margins. Healthy P&L. Then suddenly the bank calls about the overdraft, suppliers are chasing payment, and payroll looks uncomfortably tight.

What happened? Growth consumed cash faster than profit generated it.

Working capital is simple: Current assets (what you’re owed plus inventory) minus current liabilities (what you owe). When this grows, it ties up cash. When growth accelerates, working capital demands accelerate faster.

How it works:

You win a large order. Brilliant news. But you need to:

• Buy materials upfront – cash out immediately
• Pay staff to deliver – cash out this month
• Wait for customer payment – cash in weeks or months later

Result: Cash out now, cash in later. Growth consumes working capital.

Scale this across multiple orders and rapid growth, and you can be profitable whilst running out of cash.

The Three Components That Determine Cash Survival

1. Inventory (Stock)

The problem: Cash tied up buying inventory before you sell it. The longer it sits, the longer your cash is trapped.

How to optimise:

• Regular inventory reviews – identify slow movers
• Just-in-time ordering where possible
• Clear out obsolete stock
• Measure inventory turnover and improve it
• Question “safety stock” levels – are they necessary?

Target: Keep inventory as lean as possible without risking stockouts.

2. Receivables (What Customers Owe You)

The problem: You’ve delivered but cash hasn’t arrived. The longer customers take to pay, the more working capital you need.

How to optimise:

• Invoice immediately upon delivery
• Chase overdue invoices systematically
• Consider incentives for early payment or deposits
• Review credit terms for slow payers
• Set clear payment expectations upfront
• Be prepared to have difficult conversations with late payers

Target: Collect as fast as contractually possible. Payment terms should be adhered to.

3. Payables (What You Owe Suppliers)

The problem: Paying too quickly uses cash you might need. Paying too slowly damages relationships and creates operational risk.

How to optimise:

• Take full payment terms offered (if supplier offers 30 days, use it)
• Negotiate longer terms where possible
• Prioritise which suppliers to pay first (critical vs flexible)
• Evaluate early payment discounts carefully (is the discount worth the cash impact?)
• Communicate clearly if payment timing becomes challenging

Target: Match or exceed customer payment terms where possible. If customers pay in 45 days, aim to pay suppliers in 45-60 days.

The Cash Conversion Cycle

These three components combine into your cash conversion cycle:

Inventory days + Receivable days – Payable days = Cash conversion cycle

This tells you how many days of operations you’re funding from cash. The longer this cycle, the more working capital you need.

Improve any component, you improve cash:

• Reduce inventory holding time
• Collect receivables faster
• Extend payables appropriately

Combined improvements can dramatically reduce working capital requirements without changing profitability.

Warning Signs of Working Capital Problems

Watch for these signals:

🔴 Cash balance declining despite profitable P&L

🔴 Drawing down overdraft or credit facilities regularly

🔴 Struggling to pay suppliers on time

🔴 Payroll feels uncomfortably tight

🔴 Inventory levels rising faster than sales

🔴 Customer payment days extending

🔴 Management constantly talking about cash, not profit

If you see several of these, you have a working capital problem needing immediate attention.

How Growth Accelerates Working Capital Demands

Here is the trap that catches growing businesses:

Revenue grows strongly. Sounds brilliant. But working capital demands can grow even faster.

Why?

• You need more inventory to support higher sales
• More sales means more receivables outstanding
• Suppliers often don’t extend credit proportionally
• The faster you grow, the more cash you need to fund the gap

This is why growing businesses often face cash pressure despite being profitable. The working capital demands of growth consume cash faster than profit generates it.

The solution: Model working capital requirements BEFORE pursuing aggressive growth. Ensure you have cash or facilities available to fund the increased working capital.

Practical Steps to Manage Working Capital

Monthly Actions:

✅ Calculate working capital (current assets minus current liabilities)

✅ Track cash conversion cycle

✅ Review inventory aging – identify slow movers

✅ Review receivables aging – chase overdue systematically

✅ Monitor payment terms vs actual payment days

✅ Compare trends month to month

When Planning Growth:

✅ Model working capital requirements for higher revenue

✅ Ensure cash or facilities available to fund increase

✅ Build working capital assumptions into forecasts

✅ Identify which component will strain most (inventory, receivables, payables)

✅ Plan improvements before growth accelerates

Red Flag Triggers:

✅ Cash conversion cycle extending

✅ Working capital growing faster than revenue

✅ Receivables days increasing

✅ Inventory turnover slowing

✅ Payables days shortening (because you’re paying late, not by choice)

The Bottom Line

Profitable businesses run out of cash when working capital isn’t actively managed.

Growth accelerates working capital demands. Without proper management and forecasting, growth creates cash flow crisis.

The three levers are:

1. Reduce inventory (cash trapped in stock)
2. Collect receivables faster (cash coming in)
3. Extend payables appropriately (cash going out)

Improve these systematically, and you improve cash without changing profitability.

But this requires:

• Monthly monitoring
• Clear metrics (inventory days, receivable days, payable days, cash conversion cycle)
• Systematic processes (inventory reviews, receivables chasing, supplier negotiations)
• Forward forecasting of working capital needs

If your cash feels tight despite good revenue, working capital is likely the issue.
