Business finance 101 for practice owners

Revenue, gross profit, net income, and cash. Revenue is what you collect before costs. Gross profit is what a service line contributes after the direct cost of delivering it. Net income is what is left after all costs and taxes, and it is the number that actually pays you and builds equity. Cash is the balance in the account, which is not the same as profit. If you understand how every decision moves those four, you can run the practice off the numbers instead of off feel.

Revenue is what you bill and collect. Profit is what remains after the costs of earning that revenue. Cash is the money actually sitting in your account. You can post ten million in revenue and still lose money, and you can be profitable on paper and still short on cash because payment timing, taxes, and debt payments move on their own schedule. Owners get into trouble when they treat all three as the same number. They are not.

On a cash basis, you recognize income when the cash is collected and expense when the cash is paid. On an accrual basis, you recognize income when it is earned and expense when it is incurred, regardless of when the money moves. Accrual gives a truer picture of whether the business is profitable in a given period. Cash tells you what actually hit the bank. Most growing practices need to understand both, because the gap between them is exactly where cash surprises live.

It is a rolling, week-by-week projection of the money coming in and going out of your account over the next quarter. You start from today's real balance, add your recent actual spend, estimate the next several weeks by when each item will actually clear, adjust any week that would go negative, then extend to a full thirteen weeks. It is the single tool that keeps payroll and a quarterly tax payment from landing in the same week and catching you off guard, even when nothing went wrong clinically.

No. You do not have to be able to build the statements yourself or catch every accounting nuance. You do have to understand the story the three statements tell together, how each dollar you spend moves your Critical 4, and how to use that to make a better decision than you would on gut feel. Where the technical work is beyond you, get help. Not understanding the numbers at all is the part that costs you.

Business taxes are based on net profit, not revenue. Once you know your profit, you have a good sense of what you will owe. Owners who track profit through the year are rarely surprised at tax time, and they can make moves before year end instead of finding out in April. This is one more reason net income matters more than the top line.

No. Success in a downturn does not go to whoever spends the least, it goes to whoever spends the smartest. You cannot cut your way to success. Separate real investments, the spending that drives revenue or profit or buys back your time, from expenses, some of which are essential and some of which are not. Protect and even increase the investments while you trim the rest. Downturns also put assets, talent, and automation on sale, so watch for the opportunity while everyone else is only cutting.

Usually not yet. Below roughly $5 million in revenue, and while the picture stays simple, a good bookkeeper plus a CPA you trust covers most of what you need. What you can do now is keep your books clean, learn to read your Critical 4, and run a 13-week cash forecast, so the fundamentals are solid before complexity arrives. When revenue and complexity grow into the range where a blended P&L starts hiding the truth, that is when the forward-looking layer a CFO builds starts to pay for itself.
