You pull up your P&L and it says you made $180,000 last quarter. Then you look at your bank account and wonder how you are going to cover payroll next Friday. This is not an edge case. It is one of the most common financial problems in physician-owned practices, and it is almost always caused by one of three things.
The disconnect between 'profitable' and 'has cash' confuses a lot of smart people. That is because most physicians were never taught the difference between accrual accounting and cash flow. They see a profit number and assume that amount is sitting somewhere, available to spend. It is not. Here is where the money actually goes.
Problem 1: The Accrual vs. Cash Basis Disconnect
Most medical practices file taxes on the cash basis but track their financials on the accrual basis. If your bookkeeper or CPA has you on accrual accounting (which is technically more accurate and is required if your practice exceeds $30 million in gross receipts), your P&L recognizes revenue when you earn it, not when you collect it.
Here is what that looks like in practice. You see 400 patients in January. Your billing team submits $600,000 in charges. After contractual adjustments, your expected collections are $420,000. On your accrual-basis P&L, January shows $420,000 in revenue. But in January, you actually collected $350,000, because most of that $420,000 will not arrive until February, March, or later. Some of it will not arrive at all.
Your expenses, meanwhile, are very real and very cash-based. Payroll hits every two weeks. Rent is due on the first. Your malpractice premium was due in full last month. So your P&L says you made $120,000 in January, but your bank account is $70,000 lighter than the P&L would suggest.
The numbers that matter: In a typical practice, the gap between accrual revenue and cash collected in any given month runs 10-20% of total revenue. For a practice doing $400,000 per month, that is a $40,000-$80,000 disconnect. Over time, if collections keep pace with billing, this gap stays roughly constant. But if collections slow down (and they often do), the gap widens and the cash crunch deepens.
What to do about it
Run two reports side by side every month: your accrual P&L and a cash receipts and disbursements summary. The cash report does not need to be complicated. It shows opening bank balance, plus cash received, minus cash paid out, equals closing bank balance. When the gap between your P&L profit and your actual cash increase is widening, you know you have a collection problem, a timing problem, or a spending problem. The cash report will tell you which one.
Problem 2: Accounts Receivable Is Eating Your Cash
A/R is the single largest asset on most practice balance sheets, and it is also the most misunderstood. When your A/R balance grows, it means you have billed for work that has not yet been paid. That is not inherently bad; it is the nature of insurance-based healthcare. But when A/R grows faster than your revenue, you are effectively financing your payers' cash flow with your own.
Here is a scenario we see regularly. A practice has $1.2 million in total A/R. Of that, $400,000 (33%) is over 60 days old. That $400,000 represents work that was performed, expenses that were incurred, staff that was paid, and supplies that were used, two or more months ago. The practice has already spent the money to deliver that care. It just has not been reimbursed.
Now layer on the probability of collection by age bucket. Claims at 0-30 days have a collection probability of roughly 95%. At 31-60 days, it drops to 85%. At 61-90 days, you are looking at 70%. At 91-120 days, it is below 50%. And anything over 120 days has a collection probability of about 15-20%. That $400,000 in aged A/R is probably only worth $250,000-$280,000 in actual future cash.
The hidden cost: It is not just the money you may never collect. It is the cost of trying to collect it. Every aged claim requires follow-up: phone calls, resubmissions, appeals. Your billing staff spends disproportionate time on old claims that have the lowest probability of payment. Meanwhile, new claims that are easy to collect and have high probability of payment get less attention because everyone is chasing the old ones. It is a vicious cycle.
The A/R audit
Pull your A/R aging report and segment it three ways: by payer, by provider, and by age bucket. You are looking for concentrations. If one payer represents 60% of your over-90-day A/R, that is a payer-specific problem (possibly a contract issue, possibly a billing issue with that payer's submission requirements). If one provider has disproportionately aged A/R, that could be a coding issue or a documentation issue that is triggering denials for that provider specifically.
Set a target: no more than 15% of total A/R should be over 60 days. If you are above that, you have an identifiable, solvable problem. But you have to look at the data to find it.
Problem 3: Owner Distributions Exceed Actual Cash Flow
This is the one nobody wants to talk about. Your P&L says the practice made $600,000 last year. There are three partners. Each partner took $200,000 in distributions. The math works on paper. In reality, it does not.
Here is why. That $600,000 in P&L profit does not account for several things that consume cash but do not appear on the income statement. Loan principal payments reduce your bank balance but are not expenses on the P&L (only the interest portion is an expense). Equipment purchases that you capitalized hit your balance sheet, not your P&L; you paid $80,000 for a new ultrasound machine, but only $16,000 shows up as depreciation expense this year. Increases in A/R consume cash without reducing profit. And estimated tax payments, which the practice may be making on behalf of the partners, are not operating expenses.
When you add it all up, the actual distributable cash might be $420,000, not $600,000. But the partners already took $600,000. Where did the extra $180,000 come from? The line of credit. Or the reserves. Or it was taken from cash that should have covered next quarter's expenses.
A real example: We onboarded a four-physician practice that was showing $1.1 million in annual profit. The partners were each taking $275,000 in distributions ($1.1 million total). But the practice was also making $120,000 per year in loan payments on a building renovation (only $45,000 was interest expense), had capitalized $90,000 in equipment, and A/R had grown by $150,000 over the year. True distributable cash was about $700,000. The partners were over-distributing by $400,000 annually, and they had been doing it for three years. By the time they called us, the practice had $380,000 on its line of credit and less than two weeks of operating cash in the bank.
The distribution formula
Distributable cash = Net Income + Depreciation/Amortization - Loan Principal Payments - Capital Expenditures - Increase in Working Capital (A/R growth minus A/P growth) - Tax Reserve
Run this calculation every quarter before setting distribution amounts. If the number is lower than what the partners want to take, the conversation needs to happen, and it needs to happen with real data, not assumptions.
The Solution: A 13-Week Cash Flow Forecast
The P&L tells you whether you are profitable. The balance sheet tells you what you own and owe. Neither one tells you whether you can make payroll on March 15th. For that, you need a cash flow forecast.
A 13-week cash flow forecast is exactly what it sounds like: a week-by-week projection of cash in and cash out for the next quarter. It starts with your current bank balance and then maps every expected cash receipt (insurance payments based on your historical collection patterns, patient copays, ancillary revenue) against every expected cash disbursement (payroll, rent, insurance, supplies, loan payments, estimated taxes).
The first time you build one, it takes a few hours. After that, updating it takes 30 minutes per week. But the visibility it provides is transformational. You will know three weeks in advance if a cash shortfall is coming, which gives you time to accelerate collections, delay a non-critical purchase, or draw on your line of credit strategically rather than in a panic.
The three-account structure
Beyond the forecast, the single most effective cash management tool for a practice is a three-account structure.
Account 1: Operating account. All collections are deposited here. All operating expenses are paid from here. This is your working account, and you should maintain a minimum balance equal to 4-6 weeks of operating expenses.
Account 2: Tax reserve account. Every month, transfer 25-30% of net income (or your effective tax rate) into this account. This money does not get touched until quarterly estimated payments are due. The number one reason practices cannot make tax payments is that they never set the money aside.
Account 3: Distribution/owner account. Distributions are transferred here only after operating expenses and tax reserves are fully funded. If there is not enough cash to fund all three accounts, the distribution account is the one that gets shorted. This is the discipline that prevents the over-distribution problem.
Why This Keeps Happening
The root cause of the profit-but-no-cash problem is structural. Medical practices have a mismatch between when they incur costs (immediately, in the form of staff, supplies, and overhead) and when they collect revenue (30-90 days later, through insurance reimbursement). Every other industry that sells on credit deals with this same issue, but medical practices have an additional complication: they do not control their pricing. Payer contracts dictate reimbursement rates, and the practice has limited ability to accelerate collections beyond improving its billing processes.
This means cash management is not optional. It is a core competency that every practice needs, either internally or through an outsourced finance function. The practices that treat cash flow management as an afterthought are the ones scrambling to make payroll. The ones that build it into their monthly rhythm never have that problem.
The fix is not complicated. It is just not something most practice owners were trained to do. Track your cash separately from your profit. Forecast your cash position 13 weeks out. Set up the three-account structure. And never distribute more than you actually have. Do those four things, and the 'profitable on paper, broke in reality' problem goes away.
