The profit and loss statement is the starting point. It shows total revenue against total expenses for the month and tells you whether the practice actually made money. For medical practices, the P&L is more useful when revenue is broken out by provider and ideally by payer type (commercial insurance, Medicare, Medicaid, self-pay). This breakdown reveals which providers are generating the most revenue and which payer categories are growing or shrinking. Compare each month against the same month last year and against your budget. A single month in isolation doesn’t tell you much, but trends over several months tell you a lot.

Accounts receivable aging is arguably the most important report for a medical or dental practice. Insurance reimbursement cycles mean you always have money outstanding, and the aging report shows how much sits in each bucket (0-30 days, 31-60, 61-90, 90+). Healthy practices keep the majority of A/R in the 0-30 day bucket. When the 90+ bucket starts growing, it usually means claims are being denied, follow-up is falling behind, or credentialing issues are causing payment delays. Every dollar sitting in aged receivables is a dollar your practice earned but hasn’t collected, and the older a balance gets, the less likely you are to ever see it.

A cash flow summary shows what actually came in and went out during the month. Medical practices can look profitable on the P&L while running dangerously low on cash because insurance payments lag behind the services performed. This report helps you see whether you can cover payroll, rent, lab fees, and equipment loan payments over the next 30 to 60 days without scrambling.

The balance sheet rounds out the picture. It shows your total assets, liabilities, and equity at a point in time. Review it monthly to track how much debt remains on equipment loans, whether your operating cash reserve is growing or shrinking, and whether the practice is building equity over time. It doesn’t require deep analysis every month, but a quick review catches things that the P&L and cash flow report don’t show.

Beyond these core reports, a few practice-specific metrics are worth tracking. Collections rate (the percentage of billed charges you actually collect) tells you how effective your billing process is. Revenue per patient visit helps you spot trends in reimbursement rates. Overhead as a percentage of revenue, which for most practices should stay below 60-65%, gives you a quick read on whether staffing and operating costs are in line.

The common mistake is generating these reports but not actually reviewing them until tax time. By then, a billing problem that started in March has been bleeding cash for nine months. Set aside time in the first week of each month to review the prior month’s numbers. If you don’t have clean books to produce these reports reliably, start with small business bookkeeping that gets your financials current and keeps them that way. Accurate reports are the only kind worth reviewing.
