Quick Answer
Cash burn risk shows up in three places before it shows up in your bank balance: gross margin compression, receivables aging, and runway. If runway drops below 9 months while margin compresses, the decision was due last month — not next quarter.
What Is Cash Burn Risk?
Most companies don't run out of money overnight. They run out slowly — and then all at once. The warning signs were always there. They just weren't being read.
Cash burn is how fast your company spends its available cash. The risk isn't the spending itself — it's when spending outpaces revenue with no visibility into how long you can survive.
Cash runway = Available cash ÷ Monthly net burn
If your runway is under 6 months and revenue isn't accelerating, you have a problem. Most founders and fund managers find out too late.

Top warning signs to watch:
- Gross margin compression — Revenue grows but margins shrink. Costs are growing faster than sales.
- Receivables aging — Customers take longer to pay. Cash position deteriorates even when P&L looks healthy.
- Payables acceleration — You pay suppliers faster than you collect. An invisible cash gap forms.
- Runway under 9 months with no clear path to profitability — Not yellow. Red. Fundraising takes time.
One signal is noise. Two together is a warning. Three is a decision overdue.
Why This Is Harder to See Than You Think
Financial reports show what happened. They don't show what's coming.
A company can show positive net income while burning through cash. Accrual accounting lets revenue appear before cash is collected — and lets expenses be deferred. This is why cash flow statements matter more than P&L for survival decisions.
In practice, tools like Datrix help detect this automatically by analyzing financial data and cash flow patterns — surfacing trend changes weeks before they appear in a quarterly report.

- Net cash from operations (not net income)
- Days Sales Outstanding (DSO) trend
- Days Payable Outstanding (DPO) trend
- Runway recalculated every month — not quarterly
The Decision You Need to Make
If your runway is under 9 months:
- Cut non-essential burn immediately
- Accelerate collection cycles
- Start fundraising or revenue conversations now — not when you're at 3 months
Waiting is the most expensive decision you can make.
FAQ
How do you calculate cash runway?
Divide available cash by average monthly net burn (cash out minus cash in). SAR 3M of cash with SAR 500K monthly burn equals 6 months of runway.
What's the most important cash signal to watch?
Net cash from operations. It's the only number that can't be inflated by accounting timing — it shows whether the business is actually generating cash, not just revenue.
Can a profitable company still run out of cash?
Yes. Accrual accounting lets you book revenue before customers pay and defer expenses. A company with positive net income but rising DSO and falling DPO is burning cash even though the P&L looks fine.
How often should I review runway?
Monthly, at minimum. Quarterly review is too slow — by the time a quarterly report shows the problem, it's already 60–90 days old.
When should I start fundraising?
When runway is between 9 and 12 months. Below 6 months you have no leverage. Below 3 months you may not survive the diligence cycle.
