Key Takeaways

  • Schedule this review for the third week of the month following a quarter end to ensure all bank reconciliations and IRS Form 941 filings are finalized.
  • Focus exclusively on three specific metrics, Net Margin, Revenue per Employee, and Days Sales Outstanding, to identify operational rot without getting lost in minor line items.
  • Use the final 20 minutes to verify your estimated tax payments against actual year-to-date profit to avoid underpayment penalties at year-end.

How do I run a quarterly financial review in under 90 minutes?

You finish a quarterly review in 90 minutes by ignoring 80% of your P&L and focusing only on the levers that actually move your bank balance. If you're doing $1 million to $5 million in revenue, your job is no longer to categorize every coffee receipt; your job is to spot structural shifts in your margin before they become permanent losses.

Most owners waste hours looking at their P&L because they treat it like a history book instead of a diagnostic tool. By the time you reach $2 million in annual revenue, your bookkeeper should have the data cleaned and reconciled by the 15th of the month. If you're still hunting for missing invoices in week three, your first problem is your accounting process, not your financial strategy. A proper review requires you to sit down with a pre-formatted report that compares this quarter to the same period last year and the preceding quarter. This perspective reveals whether a dip in cash is a seasonal fluke or a sign that your COGS is creeping up. You're looking for anomalies, not balance. If payroll jumped 12% but revenue only climbed 3%, you have a productivity leak. If your marketing spend stayed flat but lead quality dropped, your agency is coasting. You have 90 minutes to find these three red flags and set the correction for the next 90 days. Anything else is just staring at numbers.

Phase 1: The Margin Audit (30 Minutes)

This is where you determine if you're actually getting paid for the stress you take on. Start with your Gross Margin. If you run a service business, like a 15-person HVAC crew, and your margin dropped from 45% to 40% since January, you've likely ignored a price increase from a supplier or your technicians are idling between jobs. Check your net profit next. If your net is shrinking while revenue grows, you're 'scaling' your way into a crisis.

  • Compare against the SBA size standards to ensure your growth hasn't pushed you into a new regulatory tier without the corresponding budget for compliance.
  • Flag any expense category that grew more than 10% quarter-over-quarter without a direct link to new revenue.
  • Calculate Revenue per Head: Total revenue divided by total headcount (including contractors). If this number is falling, you're over-hired.

Phase 2: The Cash Flow Friction Test (30 Minutes)

Profit is an opinion; cash is a fact. Use this window to look at your Accounts Receivable aging report. If your Days Sales Outstanding (DSO) has crept from 32 days to 45 days, you're effectively giving your customers an interest-free loan while you pay interest on your own lines of credit.

  • Review the 'Big Three' vendors: Are you still getting the best rates from your primary suppliers, or are you paying a convenience tax for a five-year-old relationship?
  • Sweep the subscriptions: Have your ops manager list every software seat over $50/month. If nobody used it in the last 30 days, kill it immediately.
  • Tax Check: Compare your year-to-date net income against the quarterly estimated payments you sent to the Treasury. If you're significantly ahead of last year's pace, you need to increase your Q3 payment to avoid a nasty surprise in April.

Efficiency is the only moat that matters when your competitors are chasing 'scale' at the expense of profit.

Phase 3: The Action Plan (30 Minutes)

Spend the final third of your time on the future. Don't just record what happened. Pick two specific corrections. If your payroll-to-revenue ratio is high, your action is a hiring freeze or a performance review cycle. If your cash is sitting idle, move it to a high-yield vehicle like Live Oak Business Savings to capture a 4% to 5% return on your reserves.

Write down your two 'Must-Fix' items for the coming quarter and email them to your lead admin or CPA before you stand up from the desk. If you don't send the email, the 90 minutes was just a hobby. Check your calendar for three months from today and protect that time block now.
