Profit Is Opinion, Cash Is Fact

Ninety days of money that actually lands, not visits on a calendar.

The concept

Cash conversion cycle

Smaller-firm finance

The days between paying for work and being paid for it, a gap you finance yourself.

Profit is an opinion. It is assembled from judgments — when to count revenue, how to spread a cost, what counts as an asset. Reasonable people get different answers. Cash is a fact. It is in the account or it is not.

Businesses die of the second thing long before the first one looks wrong.

Each stage costs days, and you finance the days. The total — not any single stage — is what your runway must cover.

Composite, someone who has just gone out on their own. $12,000 in the account. Month one brought in $1,200. Month two, $3,500. Month three, $7,800. The work was there the whole time. The money arrived late.

Meanwhile $1,500 a week goes out whatever happens. $12,000 ÷ $1,500 is 8 weeks. That is the runway, and nobody put it in the business plan.

Between doing the work and holding the money there is a queue. Work done. Bill sent. Bill reviewed. Bill paid. Every stage takes days. Add them up and you get the cash conversion cycle. Every day in it is a day you finance somebody else’s process for free.

Growth makes this worse, and that is the part nobody expects. More work means more delivered before the earlier work has been paid for. A growing business with a long cycle runs out of cash faster than a flat one. Profitable companies fail this way every year.

There are only three levers. Shorten a stage. Get paid earlier in the queue. Or hold enough cash to survive the gap. The third is not a strategy. It is what you pay for not having used the first two.

Go deeper: three things a school would add

Model the cycle weekly, not monthly. Monthly averages hide the week the balance touches zero, and that week is the only one that can end the business.
One stage slipping thirty days is not a thirty-day inconvenience: it moves every downstream payment, so the effect compounds across everything already in flight.
Runway is measured in weeks of fixed costs, not in dollars — how long the doors stay open with nothing arriving.

Work the case

Two decisions. Choose before you read the reasoning. The wrong answer is the one worth understanding.

Case 1

Revenue doubles this quarter. Your cycle is 60 days and margins are healthy.

Choose one — the reasoning opens after you commit.

Case 2

You can cut the review stage from 30 days to 20, or raise prices by 5%. Not both this quarter.

Choose one — the reasoning opens after you commit.

Now on a psychiatric practice

Cash now: 12,000, the bank, today. Not the pipeline, not "owed." In the account. Month one lands 1,200: cash-pay only, because insurance claims may not clear in thirty days for a new practice, and some don't clear in sixty.

Month two lands 3,500, the first checks: late, short, and some denied. Month three lands 7,800, if credentialing holds. That "if" is the whole page.

Burn: 1,500 a week, rent, EHR, malpractice, collab, phone, software, and you eating. Write it as a week, not a month.

Weeks are how you run out. And the red number: runway = 12,000 ÷ 1,500 = eight weeks of oxygen before a single insurance check has to arrive on time.

Not ninety days of bookings. Eight weeks.

Schools call this the cash conversion cycle: money goes out the day you see the patient; it comes back when the payer feels like it.

The gap is what you live in.

You've been deciding on "booked." What is booked? A promise somebody else made to your calendar. Cash is a promise the bank already kept.

Profit, revenue minus expenses on paper, is an opinion about the future. It can be true and you can still be out of money in week nine. Both at once.

Walk the ninety days, with the landings arriving through each month, not on the last day.

End of week four: 7,200. End of week eight: 4,700, the low point, three weeks of burn.

Week thirteen: 5,000. Did she survive? Yes. On paper she was profitable in month three, and she was three weeks from zero in month two. Both true.

Now slip credentialing thirty days. Common. Month three lands about 2,000 instead of 7,800. Below zero.

Same calendar. Same "booked out." Different bank. The practice didn't fail. The timing failed. The timing is the business.

The question, as it actually gets asked

Composite questions — blended from the operator rooms, never one person's words.

Read these for the method, not the answer. The next question you have will not be on this list — the point is that the concept above answers it anyway.

Which concept this really isRunway isn't a savings target, it's a gap you finance: the days between doing work and being paid for it, plus the weeks before enough work exists.

How you work it outCompute the cycle, not a vibe: weeks until the first payer contract is effective, plus the days from claim to deposit, plus fixed costs across the whole span. A composite 56-day cash cycle behind a credentialing chain means the first meaningful deposit lands months after the first patient.

The mental model that makes it hard"Six months of expenses" is a rule of thumb detached from your own arithmetic. Two practices with identical savings and different payer mixes have completely different runways.

The Monday rule, what do you actually run this week?

Booked is a promise to your calendar. Cash is a promise the bank already kept.
