Why your P&L isn't enough
Every owner I meet looks at two numbers: what came in, and what is in the bank. Both are real. Neither tells you anything you can act on.
The problem with a P&L is that it reports outcomes after they are finished. By the time margin compression shows up in your income statement, the decisions that caused it were made ninety days ago — a payer mix shift, a clinic that quietly slipped to sixty percent utilization, a BCBA who left in April and took eleven hours a week of billable capacity with them.
Financial statements tell you what happened. What you need is a set of numbers that tell you what is about to happen, while you can still change it.
Twelve is about right. Fewer and you are missing something structural. More and you stop looking at any of them.
I group them in four sets of three, because that is how the business actually works: are we delivering care, is each hour profitable, are we getting paid, and can we keep the people who do the work.
Set one: capacity
This is the engine. In ABA you sell clinician hours, and almost every capacity problem shows up here first.
1. Billable utilization, by role
Billable hours divided by available hours, tracked separately for BCBAs and RBTs. Blending them hides everything — the two roles have completely different targets and completely different failure modes.
Watch the trend more than the absolute level. Every practice has its own structural ceiling based on supervision model, drive time, and documentation load. A clinic that ran at seventy-two percent for six months and is now at sixty-four has a problem worth finding this week, regardless of what the "industry benchmark" says.
Track it by clinic, not just company-wide. Averages hide the one location that is failing.
2. Authorization realization
Delivered hours divided by authorized hours.
This is the most underused number in ABA, and it is often where the money is. You fought for the authorization. The family needs the hours. If you are delivering seventy percent of what is authorized, the gap is not a billing problem — it is scheduling, staffing, or attrition, and it is pure lost margin on capacity you already committed to.
It also matters clinically. Under-delivered authorizations mean children are not getting the intensity their treatment plan calls for.
3. Cancellation and no-show rate
By clinic, and ideally by clinician.
Cancellations are the silent margin killer, because your costs are largely fixed within the week. An RBT scheduled for a session that cancels at 8am is paid anyway. Above roughly fifteen percent, this stops being noise and starts being the difference between a profitable clinic and a marginal one.
If one clinician's cancellation rate is double the clinic average, that is a specific, solvable conversation.
Set two: unit economics
Capacity tells you how much you are delivering. These tell you whether delivering it is worth doing.
4. Revenue per billable hour, by payer
Your blended rate is nearly useless as a management number. What you need is the rate by payer, tracked over time.
This is how you discover that the payer representing thirty percent of your volume pays eighteen percent below your average, which means growth in that segment actively dilutes margin. It is also the number you need in hand before any contracting conversation. Owners who negotiate rates without knowing their own realized rate per hour by payer are negotiating blind.
Use realized revenue, net of denials and write-offs — not the contracted rate. The gap between the two is often larger than owners expect.
5. Direct cost per billable hour
Clinician wages, taxes, and benefits divided by billable hours delivered.
The subtlety: your cost per billable hour rises when utilization falls, even if nobody got a raise, because you are spreading the same salaries across fewer billed hours. That makes this number a useful cross-check on utilization — if cost per hour is climbing and wages are flat, you have a capacity problem, not a compensation problem.
6. Contribution margin by clinic
Revenue minus direct clinical cost minus clinic-level fixed costs — rent, clinic management, local overhead — before corporate allocation.
Company-wide EBITDA can look fine while one clinic quietly loses money every month. This is the number that finds it. It is also the number that tells you whether a de novo is tracking to its ramp or falling behind, which matters both operationally and, later, in diligence.
Set three: revenue integrity
You can deliver every authorized hour and still not get paid. In ABA this is where a startling amount of value leaks.
7. Clean claim rate
The percentage of claims paid on first submission without rework.
Below ninety-five percent, you are funding a billing team to fix problems that should not exist. Each rework cycle costs staff time and delays cash by weeks. And the root cause is usually upstream of billing — a credentialing lapse, a stale authorization, a documentation gap — which means the fix is upstream too.
8. Denial rate, with reasons
Not just the percentage. The categories.
Denials cluster. Authorization expired, service not covered, credentialing mismatch, documentation insufficient, timely filing. Three or four categories will account for most of your denials, and each has a different owner and a different fix. A denial rate with no reason coding attached is a number you cannot act on.
Track recovery separately — of what gets denied, how much do you eventually collect? A practice that denies at eight percent but recovers most of it is in a very different position from one that denies at eight percent and writes it off.
9. Days sales outstanding, with an aging bucket
Average days from service to cash, plus the percentage of AR over ninety days.
DSO alone can look acceptable while a growing tail of old receivables sits underneath it. The over-ninety bucket is the one that predicts write-offs, and it is the number a buyer will attack hardest in a working capital negotiation. Every dollar of aged AR you clean up now is a dollar you do not argue about later.
Set four: people and durability
The first nine numbers describe this month. These three tell you whether the business still works next year.
10. Clinician turnover, rolling twelve months
Separately for BCBAs and RBTs.
RBT turnover is structurally high across the industry, and a number that looks alarming in another sector may be normal here. BCBA turnover is the one that hurts — each departure takes supervision capacity, caseload continuity, and often families with it.
Track the trend and track it by clinic. A single location with turnover well above your average has a management problem, and it will show up in utilization and cancellations within two quarters.
11. Caseload per BCBA
Active clients supervised per BCBA, against your supervision model.
This is a financial metric and a clinical one, and the two point in opposite directions. Higher caseloads improve margin until the point where supervision quality degrades — at which case outcomes suffer, families leave, and payers start asking questions during audits.
Know your ceiling and manage against it deliberately. If you cannot say what your maximum defensible caseload is, you are not managing this number, you are just watching it drift.
12. EBITDA margin, trailing twelve months
The summary number, on a rolling basis rather than month by month.
Monthly EBITDA in ABA is noisy — authorization timing, payer batches, seasonal cancellation patterns. Trailing twelve months strips that out and shows the actual direction. It is also, not incidentally, the number any future buyer will start from.
Reading them together
The value is in the interaction, not the individual figures. A few patterns worth recognizing:
Utilization down, cancellations flat, turnover up. You lost clinicians and have not backfilled. A staffing problem, not a demand problem.
Utilization steady, contribution margin falling. Your payer mix moved. Check revenue per hour by payer.
Authorization realization falling while intake is strong. You are winning new clients you do not have capacity to serve. Growth is outrunning staffing, and it will damage payer relationships and family trust before it shows up in revenue.
DSO rising with a stable clean claim rate. Not a billing quality problem — likely a payer slowing down. Worth a contracting conversation.
Everything fine except over-ninety AR. Collections follow-up has stopped happening. Usually a person problem, and usually fixable in a quarter.
Making it real
A dashboard nobody reads is worse than no dashboard, because it creates the impression of control. Three things make the difference:
One page. Twelve numbers, current month, prior month, trailing twelve, and a target. If it does not fit on a page, it will not get read.
By the tenth. Data about last month delivered on the twenty-eighth is history. Delivered on the tenth, it is still actionable. This is the single most common failure — not the metrics, the timing.
One owner per number. Every metric belongs to a named person who is expected to explain movement. Numbers with no owner drift.
You do not need new software for this. Most ABA practices can build all twelve out of their practice management system and their general ledger, in a spreadsheet, in a couple of weeks of focused work. The constraint is almost never tooling. It is deciding which twelve numbers matter and then actually looking at them every month.
Numbers tell you what happened. The job is to know what they mean, early enough to do something about it.
If you want help deciding which twelve are right for your practice — the list shifts with size, payer mix, and model — that is a straightforward conversation.
