Law 8 of the JRCMO Laws of Marketing
The Check-Writing Test
When the owner signs the check, their mind has to land on a revenue number they care about. If it lands on nothing, the account is already gone.
The Check-Writing Test is Law 8 of Joshua Ramsey's JRCMO Laws of Marketing. It states that marketing is tied to revenue or it is tied to nothing. Every month a business owner signs a check for marketing, and in that moment their mind lands somewhere. If it lands on a number they care about, such as fifty new customers or three hundred booked jobs, they sign without friction. If it lands on nothing, the account is already lost, however good the work is. That's why the plan is built backward from revenue to the lead, the KPI is agreed before work starts, and it gets written into the agreement. Brand, design and content all drive revenue, but none of them replace it. Five million impressions is never a finish line. Law 8 pairs with Law 1, Two Meanings of ROI, and Law 5, the Law of Thirds, which supplies the backward math.
What's on your memo line?
Tell it what you look at when you pay for marketing and three numbers about your business. You'll see the one number your check should be buying, and whether it's locked in.
When you sign the monthly marketing check, what does your mind land on?
Is it locked in?
Where this law came from
I've watched accounts end where the work was good. The ads were built right, the site was better than before, the reports went out on time. None of that mattered. When the owner sat down to sign the check, his mind landed on nothing, so he stopped signing it. Whether his expectations were fair didn't matter either. If the number had been hit, the account would still be there. So now the number comes first. I build the plan backward from revenue, we agree on the one KPI the owner will remember at signing time, and it goes in writing.

What it gets you
Every conversation stays on money. The owner signs without friction because they can name what the check bought, and you know exactly what you're being judged on.
Where it bites back
Owners change the number with the wind. Restate it at the start of every meeting, confirm it at the end, and when it moves, the work moves with it. Going deeper, into margins and which services carry more profit, takes more time and is priced that way.
Questions people ask about the Check-Writing Test
What is the Check-Writing Test in marketing?
It asks what a business owner's mind lands on when they sign the monthly marketing check. If it's a revenue number they care about, the relationship holds. If it's nothing, the account is at risk however good the work is.
What KPI should a fractional CMO or agency be measured on?
A revenue number the owner will remember at signing time: new customers, booked jobs, or revenue and profit. Impressions, clicks and followers support that number. They aren't the number.
How do you work out how many customers marketing needs to produce?
Divide the monthly marketing cost by the gross profit from one new customer. That's the break-even count. Every customer past it is the return. Then work backward through close rate and lead volume to see what the funnel needs.
What if the owner keeps changing what they want to measure?
Open every meeting by restating the main KPI and asking if it has changed, and close every meeting by confirming it. If it changes, agree that the next hour of work changes with it, and keep the recording and the email.
