Cash Flow Gap in Group Practices



A group practice we work with grew from about $100,000 a month in revenue to around $140,000 a month over the course of a year.

That same year, their cash went backwards. Twice, the owner moved money in from personal savings to cover a payroll run.

Nothing was actually wrong with the business. Revenue was up 40 percent, the clinicians were full, and the profit and loss statement looked healthy. The money just kept arriving after it was needed.

That distance between earning a dollar and being able to spend it is the cash flow gap in group practices, and it is the most common reason a growing practice feels broke while the numbers insist otherwise.

What the cash flow gap in group practices actually is

Every session you hold has three dates attached to it, not one.

The date of service. A clinician saw a client on the 14th. That is when the revenue was earned.

The date of payment. The claim went out, the payer processed it, and money moved 15 to 45 days later. Sometimes longer.

The date the money is usable. It cleared your bank, minus processing fees, bundled into a lump deposit with a few dozen other clients.

Your profit and loss statement runs on the first date. Your bank account runs on the third. Your payroll runs on a calendar that does not care about either one.

That is the whole problem. Not overspending, not bad pricing, not a clinician underperforming. A timing mismatch between an obligation that arrives every two weeks and revenue that arrives whenever the payer gets to it.

A practice can be profitable every single month and still run out of cash. Profit measures a period. Cash measures a moment. Those are different questions, and only one of them gets asked on payroll Friday.

Why growth makes the gap wider before it makes it smaller

Here is the part that surprises owners, and it is worth sitting with.

Adding a clinician does not close the gap. It opens a new one.

Walk it through. You hire a therapist in March. Depending on your model, you are paying them from their first full week, either as salary or as a split on sessions they have already delivered. Meanwhile the claims for those March sessions pay in April, maybe May.

So for roughly the first six to ten weeks, that clinician is a pure cash outflow. You are funding their pay out of money you collected for somebody else's work.

Rough math on one hire. A clinician seeing 20 sessions a week at a 50 percent split on a $130 session is earning around $2,600 a month in pay you owe almost immediately. Push their collections out 45 days and you are floating somewhere in the range of $4,000 to $5,000 before the first dollar of their revenue lands. Treat that as an illustration and run it on your own split and your own payer timing, because both of those move the number a lot.

Hire three at once, which is exactly what a growing practice does, and that is a five figure hole opening up in a month where nothing went wrong.

Layer a build out or a second location on top of it and the hole gets deeper before it gets shallower. The practices that hit a wall here are usually not the struggling ones. They are the ones growing fastest.

Four numbers that tell you how wide your gap is

You cannot manage this by feel. These four are worth knowing cold.

Days to payment. Average days from date of service to money in the bank, broken out by your top payers. This is the literal width of your gap. If it is 21 days for one payer and 52 for another, you have just learned which contract is quietly funding your payroll and which one is straining it.
Weeks of payroll sitting in the bank. Take your cash on hand and divide it by one payroll run. Under two weeks is where the 11pm math starts. We generally like to see practices holding six to eight weeks of operating expenses, the same benchmark we use for cash reserves.
AR over 90 days. Money you earned and have not collected. Anything past 90 days is not a timing problem anymore, it is a collection problem, and those are two different conversations with two different people.
Your own draw measured against actual profit. Growth stretches are exactly when owner distributions quietly outrun what the business made. It feels fine right up until the month a payer runs slow.

None of those numbers mean anything alone. Together they tell you how many weeks of runway you have, which tells you whether you can afford the thing you are about to do. That is the only reason to track them.

Closing the gap

Four levers, in the order most practices should pull them.

1. Fund the gap before you grow, not during. This is the least exciting and most effective move on the list. Before you add a clinician, set aside roughly six to eight weeks of what that clinician is going to cost you. If you run Profit First, this fits naturally as a dedicated account that holds the hire before the hire happens.

2. Stagger your hires. Three clinicians starting in the same month is three overlapping cash holes. The same three spread across a quarter is one hole at a time, each one partly funded by the last hire's collections finally coming online. Same growth, very different March.

3. Confirm the hire actually pays for itself. Some do not, at least not at the split you offered. The gap is survivable when the clinician is profitable on the other side of it. It is not survivable when they were never going to be. That is a modeling question, and it takes about fifteen minutes with real numbers rather than a gut call. Our post on clinician profitability walks the math.

4. Get the billing side reviewed by someone outside your practice. Part of your gap is structural and unavoidable. Part of it is claims going out late, denials nobody reworked, or a payer reimbursing under your contracted rate. That second part is a billing question rather than a bookkeeping one, and it deserves an outside review once or twice a year. Ask specifically for contracted rates versus actual reimbursement, denial and rework patterns, and AR aging by payer. We wrote about where that line sits in why your EHR and QuickBooks don't match.

One caveat worth naming plainly. If your books are kept on the cash method, your profit and loss statement already reports money when it arrives rather than when it was earned, which hides the gap instead of showing it to you. The IRS lays out the difference between the cash and accrual methods{target="_blank"}. Either one is fine to run a practice on. Just know which one you are reading, because the story they tell about a big growth month is not the same story.

Cash flow gap in group practices: the short version

The cash flow gap in group practice is a calendar problem. You earn revenue on the date of service and collect it 15 to 45 days later, while payroll arrives every two weeks regardless. That is why a record revenue month can still end with an owner moving personal money into the business.

Growth widens the gap before it closes it. Every new clinician represents six to ten weeks of pay you float before their first collections land, which is why the practices that hit a wall are so often the ones expanding fastest.

Track four numbers: days to payment, weeks of payroll in the bank, AR over 90 days, and your draw against real profit. Then fund the gap before you grow, stagger your hires, confirm each hire is actually profitable, and get the billing side looked at by someone outside the practice about once a year.

None of that makes the gap disappear. It turns it into something you planned for instead of something that happens to you, and that is a very different thing to run a practice on.

If you want to pressure test whether your next hire clears the gap, our clinician profitability tool is free and walks your own numbers.
