The specific metrics depend on your business, industry, and stage of growth. But there are core numbers that every fractional CFO should be monitoring and explaining to you on a regular basis.

Cash flow is the most important starting point. Not just how much cash you have today, but a rolling forecast of where cash will be in 30, 60, and 90 days. Your fractional CFO should be projecting inflows from expected revenue and receivables against outflows like payroll, rent, loan payments, and vendor bills. Profitable businesses fail because of cash flow problems all the time. Knowing your cash position weeks in advance gives you time to act instead of scramble.

Gross profit margin tells you how much money you keep after the direct costs of delivering your product or service. If your gross margin is shrinking, it means your costs are rising faster than your prices or you’re discounting too aggressively. This number should be tracked monthly and any changes should be flagged before they become trends.

Net profit margin shows what’s left after all expenses including overhead, taxes, and debt service. Comparing gross and net margins reveals how much your overhead is eating into profitability. A business with strong gross margins but weak net margins has a spending problem, not a pricing problem.

Accounts receivable aging matters if you invoice clients. How much is outstanding, how old is it, and which clients are consistently late? Days sales outstanding (DSO) measures how quickly you’re collecting. If DSO is climbing, your cash flow will suffer even when revenue looks healthy on paper.

Revenue concentration is a risk metric most business owners ignore. If one client represents 30% or more of your revenue, losing that client could be devastating. A fractional CFO should flag concentration risk and help you build a plan around it rather than letting you discover the problem after it’s too late.

Break-even analysis tells you exactly how much revenue you need to cover all fixed and variable costs. This is essential for pricing decisions, hiring decisions, and evaluating whether a new location or product line makes financial sense before you commit.

For businesses investing ahead of revenue, burn rate and runway are critical. How much are you spending each month beyond what you’re earning, and how many months of cash do you have at that rate? These numbers drive fundraising timing and spending decisions.

Customer acquisition cost and lifetime value matter for any business spending on marketing and sales. If it costs $500 to acquire a customer who generates $2,000 over their lifetime, that’s healthy. If acquisition costs are climbing while lifetime value stays flat, your growth strategy needs a hard look.

Beyond the numbers themselves, the real value is what happens with them. A fractional CFO should meet with you regularly to walk through these metrics, explain what changed and why, and recommend specific actions. Numbers on a dashboard that nobody discusses are just decoration. The goal is turning financial data into decisions that improve your business.

If your books aren’t clean and current, none of these metrics will be reliable. Working with a bookkeeper in Franklin who keeps your financial records accurate is what makes high-level analysis possible in the first place. Good strategy starts with good data.
