As a business grows, the number of things you could track explodes — but the number that actually tell you how healthy the business is stays small. Six financial signals do most of the work. Knowing what each one means, and just as importantly what it doesn't mean on its own, is enough to spot trouble early and ask the right questions.
Cash runway
How long the business can keep operating on the cash it has, given how fast it's spending. Short runway is the signal that trumps most others — everything else matters less if you run out of cash. But context matters: a dip after a deliberate investment or a tax payment is very different from a steady slide with no explanation.
Overdue receivables
Money customers owe you that's past its due date. It's your cash, sitting in someone else's account. A rising overdue balance quietly tightens your own position and often shows up as a cash-runway problem a month later. Watch the trend and the concentration — one large late payer is a different risk from many small ones.
Gross margin
What's left from revenue after the direct cost of delivering it. Falling margin means you're keeping less from every dollar of work — usually a sign of rising input costs, underpricing, or drift toward lower-value jobs. A single month can be noise; a trend is a pricing or cost conversation.
Payroll load
Wages as a share of revenue or activity. Rising payroll load isn't automatically bad — it's expected when you hire ahead of growth. It's concerning when payroll climbs while revenue is flat or falling, or when cash is tight. Read it next to revenue direction and cash, never alone.
Customer concentration
How much of your revenue depends on your largest one or two customers. High concentration ties the health of your business to relationships you don't fully control. It's not a problem until it is — losing a customer that's 40% of revenue is an existential event, not a bad month. Worth watching closely as you grow.
Committed cost pressure
Costs you're locked into regardless of how trading goes — leases, subscriptions, financed equipment, standing contracts. As these grow, your break-even rises and your flexibility falls. In a good month it's invisible; in a downturn it's what removes your room to move.
No single number is a verdict
The most important habit is to stop reading these signals in isolation. Low cash runway plus high payroll load and rising overdue receivables is a very different situation from low runway alone. The signals interact — and the real picture is in the combination, not any one figure. Treat each as a prompt to ask "why", not as a conclusion.
