Cash flow

Cash flow is what actually happens in the bank account, and it can diverge sharply from what the P&L calls profit in a given month. A practice can be profitable on paper and still feel a genuine cash crunch because of timing (a loan payment, a large lab bill, or payroll landing before the week's insurance deposits clear), and that whiplash is what drives a lot of owners to feel like the numbers don't add up even when, on paper, they do.

The fix is mostly about timing, not more revenue. Moving payroll to a consistent bi-weekly schedule so it lands after the practice's biggest deposit days, mapping rent and loan payments so they don't stack up in the same week as payroll, and avoiding a credit card habit that creates a false sense of comfort followed by a painful bill: these are the practical levers that smooth cash flow without changing a single thing about production.

Ryan's rule for owner pay works off cash flow directly: find the point in the month when the balance is naturally lowest, keep one month of operating expenses as a buffer at that low point, and anything above that buffer is genuinely safe to draw as profit, a simpler and more honest test than eyeballing the account on a good day.
