Bookkeeper for ABA Therapy Providers

An ABA practice lives on billable hours and the cash that comes back from them. The gap between the two is wider and slower than most owners expect, which is exactly why the books need to be built around it.

How does the money come in for an ABA clinic?

For an ABA practice, the revenue model is all billable hours. There is no subscription and no membership retainer the way a service business has one. You bill a therapy hour, and the payer or the family pays for it, usually weeks or months later.

Those hours come in two streams that run on different codes and different rates. The direct therapy hour, delivered by an RBT (registered behavior technician), is billed under a code like 971 and carries a rate most clinics report somewhere in the $35 to $75 per hour range, depending on the state and the payer contract. The supervision hour, spent by a BCBA (board certified behavior analyst) on the same client, bills under a code like 97155 and runs about $100 to $150 per hour. They are different rates because they are different jobs and the cost behind them is different. A clinic needs to see them as separate money, not one blended one.

Neither line pays out today. Denials, prior authorization that cuts the approved hours, and resubmissions sit between the invoice and the deposit. A practice that books the invoice as revenue and ignores the delay will show a profitable month that cannot pay its rent. The rule that works here: the billed line and the received line are separate rows, and the owner reads the difference.

What costs the most in an ABA clinic?

Labor, by a wide margin. The wage you pay an RBT is only one piece of it. On top of that sits the employer side of payroll taxes and the supervision time the BCBA spends on the same client. Even when the owner does that supervision themself, it is a real cost because it is time not spent on another billable client.

Turnover adds a second layer of cost. Reports we have seen put annual RBT turnover somewhere from 18 percent to 68 percent, depending on the study and the region. The real loss from turnover is not the leaving tech. It is the empty seat with no billable hours, the training and orientation of the next hire, and a scheduled client with no provider during the gap. Hardly any of it shows up in the regular payroll line.

Rent is real but small in comparison. An office space runs about $1,500 to $4,000 a month, and a practice that works in homes spends far less. The money that moves a clinic is in the people, both for what they generate and for what they cost.

What usually goes wrong in an ABA clinic's books?

The most common mistake is recording revenue at the amount billed instead of the amount collected. The full amount you invoice almost never arrives. A payer has a contract rate below your rate sheet, a claim gets denied and only resubmitted for part of the hours, or prior authorization cuts the approved time. A month that bills for $40,000 in hours can collect $25,000. Both numbers are real, and when the books show only the larger one the clinic looks healthier than the bank account actually is.

The second fault is blending the two services into one revenue entry. A direct RBT hour at $50 and a BCBA supervision at $125 are different enough that the margin built into each is different. Squeeze both into a single therapy income row and you cannot tell which one carries the business. That single row hides the most important number in the clinic, so we keep them apart.

The third fault is the W2 vs 1099 mix. If an RBT works the schedule you set, under your supervision, doing the same tasks your paid employees do, there is a real employment classification question in most states. The books cannot answer the legal side of that, but they can keep the two cost lines separate so the difference in what each hour actually costs you is visible.

What should be tracked separately in the books?

At least three separations matter. On the revenue side it is service line: RBT direct hours in one row, BCBA supervision in another. On the cost side it is the employment form: W2 pay and everything costs with it, then 1099 contractor pay alone. And on both sides it is the payer.

The RBT and supervision revenue lines are the margin of the business. When you track at two different speeds for a client, the rate is the different, the payer cycle is different, and the profit in each can swing in different directions. The per-line view tells you whether direct services feed the clinic or whether the supervision is the load that carries it. It is the answer to what your practice actually makes money doing.

The cost side of that same coin is the employment form. Whether the employee is W2 costs you the wage plus employer tax, and often a benefit in such. The 1099 contractor is a different set of the amount because no payroll tax and no benefit. When both live in the same account you have a number that matches neither. You need the two separate to know the true cost of a billable hour.

And payer matters. Commercial insurance, a state plan, and a direct or an out of pocket family payer all ride on different rates, different approval paths and different payment schedules. Run them together and you see a blended average that no single payer produces. A clinic keeps margin by knowing which payer is worth a contract and which is worth a renewal.

Which numbers actually matter?

The big one is collected versus billed. Do the difference over the last six to twelve months and you know whether the clinic is honest on cash. The answer decides whether you can cover the rent and the coming payroll on the schedule payers actually stick to.

Second is the margin on the hour, not the margin on the total. Price an hour of RBT against what it costs you get the hourly price. An hour of supervision, the same way. That number is the pricing unit in a service trade as much as any other, and a report only on total revenue hides whatever is inside the hourly matter.

The third is the aging on your claims. How much of the receivable is still at 30 days, at 60, at 90 or a hundred, and which of those still carry the prior authorization. Age is the slow one in this business. Put a number of outstanding claims and you see the cost of your monthly and it becomes a real signal.

What decisions can the books support?

The biggest one is hiring. Adding a BCBA invites a six-figure salary into a small clinic, and the books can tell you whether the supervision margin and the payer flow can carry that salary before you close the deal. Adding an RBT to support a waiting client list is a much smaller test, but the cash position out of the claim cycle is what the approval should be a grant.

Second is the payer decision. When the payer line is split out and your aging shows one payer at 90 days and another at 21, the choice is science: keep the slow one at your contract volume or you'll need the days, or drop them for the faster payer with a lower rate. The books make that trade off plain.

And growth. A strong flow of pending claims can create an expansion that the existing cash does not support. The clinic that sets its enrollment growth by the cash the books show is a clinic that does not have to hit a crisis month to find the same answer.

That is the shape of good bookkeeping for an ABA practice: billable hours tracked in the units that matter, labor cost kept true alongside, and the actual claim flow brought up to speak. Read one year and the monthly numbers will tell you where the puller is anyway before the owner hears it through another channel.
