What your schedulers already know that your forecast does not
Ask your scheduler which clients are going to be a problem next month and you will get an answer in about four seconds. No spreadsheet. No report. Just a list.
Ask your revenue forecast the same question and it will tell you that every authorized hour is going to happen.
One of these two sources has a track record.
The forecast is built from the wrong document
Most ABA revenue models start with the authorization. It is the obvious place to start — it is a number, it is in writing, it came from the payer, and it is sitting right there in the system.
It is also a ceiling, not a plan. It says the payer will not object to paying for up to this much. It says nothing about whether the family can get there.
The reservoir is the honest version: of the hours you are authorized to deliver, how many will a real household with real jobs and real traffic and a real other child actually absorb. That number is always lower. On a healthy book it is 60 to 75 percent of authorized. On a book with a lot of new starts it can be under half.
Your scheduler knows roughly where each client sits on that range. They have known for months. Nobody has ever asked them to write it down in a way that reaches the P&L.
Why nobody asks
Partly because it feels soft. A forecast built on “Maria thinks the Thursday family is going to flake” does not have the same authority as a forecast built on a signed authorization.
But the signed authorization has been wrong every month for two years, and Maria has not.
The other reason is that there is no field for it. The practice management system has a place for authorized units and a place for delivered units and nothing in between. So the knowledge stays in somebody’s head, where it does no good to anyone making a hiring decision.
Capturing it without adding a meeting
You do not need a new process. You need one column.
Take the client roster. Next to each client’s weekly authorized hours, add a single column: realistic weekly hours. Then have whoever builds the schedule fill it in, once, from memory. It will take them under an hour for 40 clients because they are not calculating anything — they are reporting what they already believe.
Then update it when something changes. A new start, a schedule change, a family that moves, a client who goes from two days to four. Those are events somebody already handles. Adding “and update the realistic column” costs nothing.
Once a quarter, compare the realistic column to what actually happened. If your scheduler’s estimates are consistently off in one direction, adjust. If they are close, you now have a forecast with a track record, which is more than the authorization ever had.
What it changes
Illustrative arithmetic, not a client engagement.
Look at the last two rows. The schedulers said 600. Actual was 592. The authorization said 840.
If you staffed to 840 you hired for a third more capacity than you had work for. If you staffed to 600 you were eight hours off across the whole practice, which is a rounding error.
The objection
Somebody will say the realistic number becomes a self-fulfilling prophecy. If you plan for 600 you will never deliver 700.
That is a fair worry and it is why the reservoir belongs in the forecast, not in the goal. Your clinical team can and should push utilization up. The finance model just needs to stop pretending the push has already succeeded.
You can budget to the reservoir and target above it. What you cannot do is budget to the authorization and be surprised every quarter.
Five checks you can run this week
1. Add the realistic-hours column to the roster and have whoever builds the schedule fill it in from memory. Do not let them research it. The value is in the instinct.
2. Total it and compare to authorized. If the ratio is above 85 percent, your schedulers are being polite. Ask again.
3. Compare last year’s delivered hours to last year’s authorized hours. That ratio is your historical reservoir. It should be close to what the schedulers just told you.
4. Find the five clients with the widest gap between authorized and realistic. Those are either re-authorization candidates at a lower level or families who need a conversation, and both are somebody’s job this month.
5. Check whether any hiring decision in the last year was made against the authorized number. If it was, you now know where the idle clinical wages came from.
The number to actually track
Realistic weekly hours against authorized weekly hours, by client, refreshed whenever a schedule changes.
Pair it with last year’s delivered hours over last year’s authorized hours. One is the forecast, the other is the track record, and they should be close.
Tracking authorized hours alone is not a forecast. It is a ceiling with a chart around it.
Where this sits
This is the first of eight stages where ABA revenue leaves, and it is the one everything downstream is measured against. The reservoir is what a client will realistically receive. Every other stage is a gap between that and what was collected.
A forecast built on authorizations will overstate every month, and the overstatement compounds into hiring.
A Leak Map Assessment measures all eight — the reservoir, authorization burn, cancellations, session conversion, conversion to billed, clean claims, rate integrity and recoupments. A claims audit is a different instrument. It starts once a session has been converted and billed, and reconciles the back half of the cycle to cash.
Aimline closes the books, oversees the revenue cycle, and sits in the CFO seat for ABA practices. We run claims audits scoped to a payer book, and Leak Map Assessments that measure the full cycle — three weeks, $7,500 fixed. Either one gives us a verified number to run oversight against, and the report is yours whether or not you engage us to fix what it finds.
