7 Signs Your Business Will Run Out of Cash in 6 Months
Cash crises rarely arrive without warning. The signs are there—most business owners just don't recognize them until it's too late. Here are the seven patterns that predict a cash emergency is coming.
Declining Cash
3+ months
Rising AR
DSO increasing
Credit Line
Over 50% used
Late Payroll
Last minute
Key Takeaways
- •Declining cash balances for 3+ consecutive months signals trouble—even if you're profitable
- •Rising accounts receivable aging is often the first domino to fall
- •Increasing reliance on credit facilities to cover payroll is a late-stage warning
- •The time to act is when you spot the trend, not when you feel the pain
Most business owners who run out of cash say the same thing: "It happened so fast." But when you look at the financials, the warning signs were there for months. The problem isn't that cash crises arrive without warning—it's that the warnings look normal until they don't.
Profitable businesses run out of cash all the time. A P&L that shows positive net income tells you nothing about whether you'll make payroll next month. Cash flow is a different animal—and these seven signs indicate yours is about to become a problem.
Why This Matters
By the time you feel a cash crisis, your options are limited. Banks don't extend credit to distressed borrowers. Customers smell desperation. Vendors tighten terms. The time to act is when you see the warning signs—not when you experience the pain.
Sign #1: Your Cash Balance Is Declining Month Over Month
Look at your bank balance at the end of each of the last six months. Is it going down? Even if your P&L shows profit, a declining cash balance means cash is leaving faster than it's arriving.
The Math That Kills Companies
Month 1: $500,000 ending cash
Month 2: $465,000 ending cash (-7%)
Month 3: $430,000 ending cash (-8%)
Month 4: $380,000 ending cash (-12%)
Month 5: $320,000 ending cash (-16%)
Month 6: $245,000 ending cash (-23%)
At this rate, cash hits zero in about 4 months. But the trend was visible from Month 2.
Three consecutive months of declining cash is a pattern. Four months is a trajectory. If you're showing profit on your P&L while cash declines, something is consuming cash that doesn't show up as an expense—usually working capital growth or debt payments.
- What to check: Compare net income to change in cash. If net income is $50K but cash dropped $70K, find the $120K difference.
- Common culprits: Inventory build-up, AR growing faster than revenue, loan principal payments, large prepaid expenses.
Sign #2: Your Accounts Receivable Aging Is Getting Worse
Accounts receivable aging is often the canary in the coal mine. When customers start paying slower, it's usually because they're having their own cash problems—or because your service quality is slipping and they're withholding payment.
| AR Metric | Healthy | Warning | Danger |
|---|---|---|---|
| Days Sales Outstanding | <30 days | 30-45 days | >45 days |
| AR over 60 days | <10% of AR | 10-20% of AR | >20% of AR |
| AR over 90 days | <5% of AR | 5-10% of AR | >10% of AR |
| AR trend | Stable or improving | Slight deterioration | Consistent deterioration |
The danger isn't just the money that's late—it's the trend. If your DSO increased from 32 days to 38 days to 44 days over three months, that trajectory will continue. At 44 days DSO, you're financing an extra 12 days of revenue for every customer.
Sign #3: You're Stretching Payables Beyond Normal Terms
When cash gets tight, the first thing most businesses do is pay vendors slower. It feels like a free source of financing—but it's not. It's a signal that you're already in the early stages of a cash crisis.
- Early signal: Paying net-30 invoices at 35-40 days
- Warning signal: Paying net-30 invoices at 45-60 days
- Danger signal: Vendors calling about payment, putting you on credit hold, requiring prepayment
The Hidden Cost of Stretched Payables
When you stretch payables, you lose early payment discounts (often 2% for paying 20 days early—that's 36% annualized). You damage vendor relationships. And vendors talk to each other. Stretching payables buys time, but it accelerates the crisis.
Sign #4: Revenue Is Growing But Cash Isn't
This is the one that confuses most business owners. Sales are up! Revenue is growing! Why is cash so tight? The answer is usually working capital: the cash tied up in inventory and receivables that grows as your business grows.
The Working Capital Trap
A business with $10M revenue and 60 days of working capital has $1.6M tied up in operations. Grow to $15M and you need $2.4M—that's $800K of cash consumed by growth. If your margins are 10%, you'd need to earn $8M in profit to fund that growth from operations. Most growing businesses can't self-fund their working capital needs.
Calculate your cash conversion cycle: Days Inventory Outstanding + Days Sales Outstanding - Days Payables Outstanding. If that number is increasing while revenue grows, each dollar of new sales is consuming more cash than the last.
Sign #5: You're Using Your Line of Credit for Operating Expenses
Lines of credit are meant for short-term working capital fluctuations—not permanent operating support. If you're drawing on your line to cover regular operating expenses like payroll or rent, you're essentially borrowing to stay afloat.
Healthy vs. Unhealthy Line Usage
Healthy Usage
- Draw for seasonal inventory build
- Bridge timing gap between large sale and collection
- Pay down to zero regularly
- Usage is predictable and planned
Unhealthy Usage
- Draw for payroll or recurring expenses
- Balance never goes to zero
- Balance keeps increasing
- Usage is reactive and unplanned
If your line of credit balance has been above 50% of the limit for more than 90 days, and you can't point to a specific temporary cause, you have a structural cash flow problem—not a timing problem.
Sign #6: Your Gross Margin Is Declining
Gross margin erosion is a slow killer. A 2-point decline in gross margin might not seem dramatic—but for a $10M business at 40% gross margin, that's $200K less cash generated annually. Over time, margin erosion compounds.
- Price erosion: Discounting more to win deals, legacy customers on old pricing
- Cost increases: Input costs rising faster than prices, wage inflation
- Mix shift: Selling more of your lower-margin products/services
- Efficiency loss: More overhead creeping into cost of goods sold
Track gross margin monthly. If it's declined three months in a row, find out why. If you can't explain it, you can't fix it—and the cash impact will show up in about two quarters.
Sign #7: You're Making Payroll Decisions at the Last Minute
This is the late-stage warning. If you're checking the bank balance on Monday to see if you can make Friday payroll, you're already in crisis mode—you just haven't admitted it yet.
The Payroll Test
Can you cover the next three payrolls without collecting any new receivables or drawing on credit? If the answer is no, you have less runway than you think. Payroll is non-negotiable—if you're cutting it close, everything else in your business is at risk.
- Delaying vendor payments to make payroll
- Asking customers for early payment to cover payroll
- Owner forgoing salary to fund payroll
- Maxing credit cards to cover payroll
Any of these indicate you're in survival mode. The decisions you're making to get through this week are making next month worse.
What to Do If You See These Signs
If you recognized your business in multiple items above, here's the immediate action plan:
1. Build a 13-Week Cash Forecast
Stop guessing. Map out every expected cash inflow and outflow for the next 13 weeks. This tells you exactly when you'll hit zero—or if you won't. It's the foundation for every decision you'll make.
2. Identify the Root Cause
Is this a revenue problem, a margin problem, a collections problem, or a spending problem? The solution is different for each. Don't cut costs if the real problem is that customers aren't paying.
3. Secure Financing Before You Need It
If you'll need external capital, start the conversation now. It takes 60-90 days to secure a new credit facility. Lenders want to help businesses with problems—not businesses in crisis.
4. Accelerate Collections
Call your top 10 AR balances today. Offer early payment discounts. Send invoices faster. Tighten credit terms for new customers. AR is often the fastest source of cash in a crisis.
5. Cut Discretionary Spending Immediately
Freeze hiring. Defer capital expenditures. Cancel non-essential subscriptions. Reduce owner distributions. Every dollar you save now is a dollar of runway.
