How to build a one-page "marketing P&L" for your CEO
You don't need a perfect attribution model. You need a defensible one-pager that speaks Finance. Build it in four moves
1. Lead with the efficiency number, not the activity. Open with marketing-sourced (or influenced) pipeline and revenue, then cost per $1 of pipeline and CAC payback by channel. Activity metrics (impressions, MQLs) go in an appendix, if anywhere.
2. Benchmark every number against the table above. "Our CAC payback is 11 months" means nothing alone. "Our CAC payback is 11 months versus a private B2B SaaS median of ~20" wins the room. Context turns a number into an argument.
3. Show the trend, not just the snapshot. Over 70% of marketers lack year-over-year visibility on funnel performance. If you can show "payback improved from 16 to 11 months over three quarters," you've proven you're managing the spend, not just reporting it.
4. Tie the ask to a return. Don't request budget — propose an investment with an expected payback. "Reallocating $X from [>18-month-payback channel] to [sub-12-month channel] should add $Y in pipeline at our current efficiency." That's a sentence a CEO can say yes to.
When the CEO asks "why should we spend more on marketing?", the strongest answer sounds like this:
"Right now we acquire $1 of new ARR for about $X, with payback in [N] months — better than the ~20-month B2B SaaS median. Our LTV:CAC is [N]:1. The channels above 3:1 are capacity-constrained: every extra dollar there returns more than a dollar within [N] months. I'm asking to move $X into those channels, and here's the pipeline I expect it to produce."
No adjectives. No campaign names. Just unit economics, benchmarked, with a forecast attached. That's the difference between defending a budget and earning one.
