Plenty of marketing directors can read a budget. Few have held a monthly profit and loss account on their own business, for seven years, with cost of acquisition, conversion rate, unit value and margin on the same sheet.

That is what this file covers: 83 months, from May 2013 to December 2021. In 2018 alone the machine handles over 600,000 leads and produces over 8,500 sales, at a gross margin of 28.1%.

And two facts I prefer to all the others. The take rate does not move for six years, staying between 1.39 and 1.51%. What improves is value per customer, which more than doubles over the period. And the first two years are loss-making, owned and budgeted, for a modest cumulative amount. A curve that only ever goes up does not exist.

01 · Context

Cob Editions was my own performance marketing company. No agency fees, no rate card: revenue came from performance, meaning the gap between what a lead cost and what it returned once converted. In that model there is nowhere to hide. A negative month is negative, and you have to know why before the end of the following week.

The constraint

A business living off the gap between a buying cost and a resale price is structurally fragile. Lead cost rises when competitors bid, revenue falls when the advertiser renegotiates, and both can move in the same month. Add that an audience has a short life, that every ad fatigues within days, and that a profitable segment stops being profitable without warning. Managing that quarterly is impossible. It has to be managed monthly, with margin in front of you.

03 · The system

1 · Week one: listen and decide.

On site. Understand what the cooperative does, what its buyers and partners need to believe, and what the members are proud of. Positioning written and validated in the room, not by email.

2 · Week two: build the identity.

Visual identity designed against the positioning: name system, marks, colours, typography, and rules simple enough to be applied without a design team. Every choice tested against one question: does this raise institutional trust?

3 · Week three: ship the assets.

The working kit the cooperative actually needed: documents, signage, presentation materials, templates. Delivered with a short guide and a working session so the members could produce their own materials next month.

4 · Spend where perception changes.

The budget went into the few physical touchpoints partners actually see. Nothing was spent on deliverables that flatter the consultant.

04 · Results

Monthly P&L, May 2013 to December 2021.

05 · What it proves

A marketing director who has held a monthly P&L on their own business does not talk about budget the same way. They know what a decision costs, they know when a segment stops paying, and they know how to say no to volume that returns nothing. That is the discipline I install in companies today, at a different scale. The scale changes; the sheet does not.

Could you lay out seven years of margin, month by month?
