What changes in the books when a solo practice becomes a group?
The clearest marker is the first time someone else’s paycheck depends on your numbers. A solo practice can get by with books that answer one question, which is whether the practice made money and whether everything is organized for the tax preparer. A group practice has to answer several questions, and it has to answer them while there is still time to act on the answer. This is the point where bookkeeping stops being housekeeping you catch up on in December and starts working as the practice’s operating system.
Paying people is the first real change. W-2 clinicians and admin staff bring wage accounts, employer tax expense, and withholding liabilities that have to sit correctly on the books, along with a payday that cannot slip. Contract associates bring contractor accounts and year-end 1099s. Collect a W-9 the day someone starts and the January filing takes minutes instead of a week of chasing emails. Whether a particular person is an employee or a contractor is a decision for your attorney or tax professional, and the books record whichever answer is true. Aretha runs payroll for practices whose payroll system is already up and running, so pay periods stop living in your head.
Revenue also has to become traceable to the clinician who earned it. Deposits arrive in lumps, and a single monthly income total no longer tells you much once three or four people are seeing clients. In QuickBooks Online, classes let each clinician’s revenue and pay sit side by side, which is how you find out whether a 60/40 split actually works at your fee levels and whether the next hire helps or just adds noise. This is the everyday work of bookkeeping for group practices.
Overhead stops being one bucket. Rent, EHR seats, liability coverage, supervision time, admin support, and scheduling software behave differently as you grow. Some costs rise with every clinician and some barely move. Pick a simple, consistent way to spread the shared costs so you can see margin per clinician, and keep using that same method every month so the trend means something.
Your own compensation becomes a deliberate line. Owner pay gets recorded separately from profit, and your personal caseload gets separated from the group’s results, so you can see whether the practice stands on its own without you carrying a full schedule. How owner pay is handled depends on your entity type and current rules, so confirm the specifics with your tax preparer.
If your practice has already grown past its books, that is very normal and very fixable. Aretha does bookkeeping for mental health professionals across the country and can get the structure right before the next hire. Book a consultation with her and bring your questions.

More Questions
How much does bookkeeping cost for a private practice?
Full-service monthly bookkeeping for a private practice starts at $165 a month. Add-ons like payroll processing, bill payment, invoicing, and 1099s each have their own starting price, and catch-up or clean-up work gets quoted once I see what you have.
Read answerDo I need an accountant, a bookkeeper, or both?
Most private practices end up with both. A bookkeeper keeps your records accurate and current all year, and a tax professional uses those records to prepare returns and advise on tax strategy. The two roles work best together.
Read answerHow much should I set aside from each payment so taxes never surprise me?
Common guidance runs 25 to 30 percent of profit, and your tax preparer should confirm the right figure for your situation. The percentage applies to profit rather than to the full deposit, so knowing your real profit number is what makes the reserve accurate.
Read answerWhat makes ABA practice books harder than a therapy practice's?
It comes down to people, volume, and speed. An ABA practice runs a team of technicians and analysts, so real payroll happens every period, high session volume means revenue arrives as remittances that have to reconcile against the work delivered, and the numbers change fast when the practice grows.
Read answerWhich parts of my practice make the most money?
You can only answer this if your books split revenue by service line and you know roughly how many hours each line takes. Individual sessions, couples work, groups, testing, supervision, and workshops all earn differently per hour of your time once direct costs come out.
Read answerHow many sessions a week does my practice actually need?
Add your real overhead, the pay you want to take home, and the tax reserve your tax preparer sets, then divide by what you actually collect per session. Common benchmarks put a sustainable full caseload somewhere around 18 to 22 sessions a week. Clean books give you honest numbers to put into that math.
