Cash vs. Accrual Accounting: Why Your Profit Doesn’t Match Your Bank Account
Why your P&L can show a great month while your bank account sits still, and which report to trust for which decision.
A client said something to me recently that I hear all the time:
"Last month QuickBooks showed a $30,000 profit... but my checking account barely moved."
If you've ever looked at your reports and wondered how both of those can be true at once, you're in good company. It's one of the most common reasons therapy practice owners get frustrated with their numbers. The report says one thing, the bank says another, and you're left not sure which one to believe.
Both are right. They're answering different questions.
You don't need to become an accountant to see why. But once you understand the difference between cash and accrual, the mystery goes away, and you stop expecting two different measurements to tell the same story.
Why this matters as you grow
When you're a solo therapist, your bank balance is usually enough to run on.
Once you're running a group practice, it isn't. You're making hiring decisions, setting compensation, negotiating leases, planning growth. Suddenly you're weighing questions your bank balance can't answer:
Can I afford to hire another clinician?
Should I raise my own pay?
Is this second location actually making money?
Are we growing in a way we can sustain?
How your numbers get measured now matters as much as the numbers themselves. The report you open, and the method behind it, decides how good your answer is.
Cash accounting: what it tells you
Cash accounting records income when the money lands in your account and expenses when the money leaves. Nothing counts until it moves.
For a therapy practice, that timing matters more than most owners expect. When a clinician sees an insurance client, the money doesn't show up that day. Headway or Alma might pay you two to four weeks later. A commercial payer billed through SimplePractice or TherapyNotes can take even longer. Under cash accounting, all of that revenue lands on the day the deposit hits, not the day the session happened.
This feels natural because it mirrors what you see in your bank feed. And it's the right tool for day-to-day questions:
How much cash do I have today?
Can I make payroll this Friday?
Can I cover next month's expenses?
When the question is about money you can actually spend right now, cash accounting is the one to open.
Accrual accounting: what it tells you
Accrual accounting asks a different question. Not when the money arrived, but when the work happened.
Same insurance example. Your clinician delivered those sessions in June, so accrual records the revenue in June, even if the payer doesn't deposit until July. Expenses follow the same rule. They land when you incur them, not when the payment clears.
Lining up income and the expenses that earned it in the same month gives you a clean read on how the practice actually performed. That's why growing practices lean on accrual reports when they're making real decisions about hiring and compensation.
A therapy practice example, with real numbers
Say one clinician sees 20 insurance clients in the last week of June, at $150 a session. That's $3,000 of work delivered in June. The claims go out that week, but the payer doesn't deposit until the middle of July.
Under cash accounting, that $3,000 shows up in July, because that's when the money arrived.
Under accrual accounting, it shows up in June, because that's when your practice earned it.
Now zoom out, and you can see where the $30,000 mystery comes from. Picture a month where your clinicians earned $60,000 in sessions. Most of that is still sitting in accounts receivable at month-end, waiting on insurance. The cash that did land in June was mostly payment for April and May work. Meanwhile you paid your quarterly estimated taxes and bought some new office furniture.
Your accrual P&L shows a strong month: $60,000 earned against your costs. Your bank barely moved, because the cash coming in (old work) roughly matched the cash going out (payroll, taxes, furniture). Profit and cash told two different true stories about the same month.
Why profit doesn't match your bank account
This is where a lot of owners get stuck, so it's worth saying plainly.
Your bank balance tracks the movement of cash. Your Profit and Loss statement tracks how the practice performed. They measure two different things, and they're not supposed to match.
You can have a genuinely profitable month with almost no change in your checking account. Reimbursements are still in transit. A few big expenses cleared the same week. Quarterly taxes went out. None of that means the month went badly. It means cash and profit are moving on different clocks.
Once that clicks, a lot of financial stress goes away. You stop staring at your bank balance trying to make it confirm a number it was never measuring.
Which method helps you decide?
Skip the question of which method is "better." Ask a sharper one: which question am I trying to answer?
For today's cash position, reach for cash accounting. For hiring decisions, clinician profitability, and sustainable growth, reach for accrual. It shows how the business performed, not just when money moved.
Here's the quick version:
If you're asking... The report that helps most Can I make payroll on Friday? Cash How much cash do I have available? Cash Is this clinician profitable? Accrual Can I afford another hire? Accrual Is my practice growing sustainably? Accrual
Each report answers a different set of questions. Once you know which question you're asking, the right one is obvious.
Do you have to choose one?
Here's the part that surprises people: you don't have to pick one method for everything. Plenty of growing therapy practices use both.
It's common to file taxes on a cash basis while reviewing accrual reports through the year. Whether your practice can file cash basis depends on your entity type and your gross receipts, so confirm what you're eligible for with your tax professional. But the reporting method you file under doesn't have to be the lens you use to run the business.
Switching between those views doesn't change your books. It's the same underlying data, shown two ways.
A couple of myths worth clearing up
Accrual isn't just for big corporations. A group practice with a handful of clinicians gets real value from accrual reports, because they show ongoing performance instead of the lumpy timing of insurance deposits.
And simpler isn't automatically better. Cash accounting is easier to follow, and that has real value. But when you're weighing a hire, a raise, or a new location, the simpler report often leaves out exactly what you need to see.
Better decisions start with better information
As you grow, you'll want both reports on the desk. The skill is knowing which one answers the question you're asking right now. When your books are built for that, choices about hiring, your own pay, pricing, and expansion get a lot less stressful, because you're deciding from real information instead of a guess.
Cash tells you whether you can pay tomorrow's bills. Accrual tells you how today's business actually performed. The best therapy practice owners read both, and they know when to reach for each.
If your P&L and your bank never seem to agree
That gap between profit and cash is exactly the kind of thing clean, practice-specific books are built to explain. That's why we build reporting specifically for group therapy practices. Your reports give you what you need to hire confidently, set your own pay, and plan your next stage of growth.
If you've ever looked at a healthy bank balance and still felt unsure about your practice's finances, you're not alone.
