There is a meeting that happens in every commercial organisation, in slightly different language, every quarter.

Someone presents the numbers. The numbers are good — or at least good enough. Acquisition is up. The campaign delivered. The cost-per-acquisition is within target. The slide has green arrows. Somebody says solid quarter and the conversation moves to next quarter’s plan.

At no point does anyone in the room ask the only question that actually matters.

What did it cost to produce these numbers, in a currency the dashboard does not measure?

That question is not asked because there is no template for asking it. There is no slide for it. There is no metric, no attribution model, no performance framework in the standard marketing toolkit that would allow a competent CMO to walk into a board meeting and answer it. So the question stays unasked. The quarter closes. The numbers are filed. And somewhere, in the data nobody is looking at, something has moved.

That movement is the subject of this essay. And it is the subject of a book I have just published, called The Trust Ledger.
