The 5 Financial Metrics Every Founder Should Track (Besides Revenue)
Revenue is the metric every founder knows. It's the number on the dashboard, the line in the board update, the thing you celebrate when the month is good. It's also one of the least useful numbers for running your business day to day.
Revenue tells you what you sold. It doesn't tell you whether you kept any of it, when you'll actually see it in your bank account, or whether your business can survive the next 90 days. Founders who run on revenue alone are flying with one instrument — and it's the wrong one.
Here are the five metrics that actually matter.
1. Gross Margin
Gross margin is revenue minus cost of goods sold (COGS), expressed as a percentage. If you bring in $500,000 in revenue and your direct costs — labor, materials, fulfillment, whatever goes directly into delivering your product or service — are $300,000, your gross margin is 40%.
This number tells you how much fuel the business generates before overhead kicks in. A 40% gross margin means you have $0.40 of every revenue dollar to cover salaries, rent, software, and everything else. A 15% gross margin means you don't.
Target ranges vary by business model: SaaS companies often run 70–80%, service businesses 40–60%, e-commerce and product businesses sometimes 30–50%. What matters isn't hitting an arbitrary benchmark — it's knowing your number, tracking it monthly, and understanding why it moves.
2. Net Cash Flow
This is not profit. Net cash flow is the actual movement of money in and out of your bank account over a given period. Profitable businesses run out of cash all the time — because of timing. You invoice in March, the client pays in May. You buy inventory in April, you sell it in June. The P&L looks fine; the bank account doesn't.
Track net cash flow monthly at minimum. Better: run a 13-week rolling cash flow forecast so you can see where the pinch points are before they arrive. This is the metric that tells you whether you can make payroll next month, not whether you had a good quarter.
3. Customer Acquisition Cost (CAC) and Payback Period
CAC is what it costs you to acquire one new customer — total sales and marketing spend divided by the number of new customers in a period. If you spent $50,000 on sales and marketing last quarter and acquired 25 new customers, your CAC is $2,000.
That number only means something in context. A $2,000 CAC is excellent if those customers generate $15,000 in lifetime value. It's unsustainable if they generate $3,000 and churn after six months.
The number to pair with CAC is payback period — how many months of gross margin from that customer it takes to recover what you spent to acquire them. If your payback period is 18 months and you're growing fast, you're burning cash. Know the math before you scale the channel.
4. Accounts Receivable Days (DSO)
Days Sales Outstanding measures how long it takes to collect what you're owed. Take your accounts receivable balance, divide by average daily revenue, and you have the average number of days between invoice and payment.
A DSO of 30 means customers pay in about a month. A DSO of 75 means you're effectively lending your clients money for two and a half months — without interest. For service businesses and agencies especially, DSO is often the difference between a business that feels cash-tight and one that doesn't. Tightening your payment terms, sending invoices immediately upon delivery, and following up on overdue accounts can recover more cash than a new sales campaign.
5. Operating Expense Ratio (OpEx Ratio)
Take your total operating expenses — everything except COGS — and divide by revenue. This tells you what percentage of every dollar you bring in is consumed by overhead before you see a dollar of operating profit.
Most founders track revenue growth and assume the business is getting more efficient as it scales. Sometimes it is. Often it isn't. The OpEx ratio makes the trend visible. If revenue grew 30% last year and your OpEx ratio stayed flat or got worse, your cost structure is scaling with your revenue — which means the business isn't actually more profitable, just larger.
Watch this number quarterly. When it starts creeping up without a strategic reason (you hired ahead of a product launch, you opened a new market), it's an early warning sign.
Vera's Take
Most founders I talk to know their revenue and maybe their bank balance. That's not a financial dashboard — that's a guess. The five metrics above aren't sophisticated; they're the minimum viable set for running a real business. If you can't recite your gross margin and DSO off the top of your head, you don't have enough visibility into your own company.
Building a dashboard around these five metrics takes an afternoon. What takes longer is knowing what you're looking at when they move — and having a plan when they move the wrong direction. If you want this applied to your business, that's what Vera CFO is for.
