Tools / Bucket 9

Commercial fluency

Connecting marketing to revenue. CAC, LTV, payback period. Reading a P&L and defending budgets in language a CFO believes.

Tools and platforms

/P&L statements

Revenue, cost of goods, gross profit, operating costs (your budget lives here), operating profit. If you cannot find marketing on a P&L, you cannot defend it.

/Unit economics calculators

CAC, LTV, payback period, contribution margin. Build these in a spreadsheet. Understand how they connect: if CAC exceeds LTV, you are losing money on every customer, no matter how good the ROAS looks.

/Channel profitability analysis

Go beyond ROAS. Paid search might show 4x return but 70% is branded (people who would have bought anyway). Email might look small but has 60% repeat order margin. A busy channel and a profitable channel are not the same thing.

/AI for financial modelling

Use Claude or ChatGPT to build financial models, calculate break-even points, and stress-test assumptions. The maths is fast. The judgment on which assumptions to trust is yours.

What AI does vs what you do

AI handles
  • Aggregate data across channels
  • Build dashboards and financial models
  • Calculate metrics and spot trends
  • Scenario modelling and forecasting
  • Automated reporting to stakeholders
You decide
  • Connect marketing activity to business outcomes a CFO cares about
  • Defend budgets with honest evidence, not inflated metrics
  • Distinguish busy channels from profitable ones
  • Make hard cut decisions when something is not working
  • Present limitations honestly (what you cannot prove)

Skills to develop

/P&L reading and interpretation
/Unit economics (CAC, LTV, payback, contribution margin)
/Business case construction
/Channel profitability analysis beyond ROAS
/Finance conversation fluency
/Knowing when to kill a campaign that looks good on paper

The question is not 'is this channel performing?' It is 'is this channel making the business more money than it is costing?' A busy channel and a profitable channel are not the same thing.
