Module 5 · Grow · Lesson 2 of 4
Run a simple weekly profit and loss sheet, and pick one KPI to chase, starting with a plain definition of gross profit.
Deliverable: A P&L sheet (template provided) filled in back to week 1, plus one weekly KPI goal you'll track from here on.

Pass this stage's gate ($1,000 cumulative gross profit) and you earn your First $1K.

How to pick one number that actually matters instead of tracking everything at once.
“Revenue” is a word that hides more than it explains. If your product brought in $1,000 this month but had real costs subtracted from it — tools, materials, ads, fees — you did not actually keep all of that $1,000. What is left over is your gross profit: money in, minus what it cost to make and sell. It is the number that decides whether your business is actually working, not just busy.
A weekly P&L is a simple habit: every week, you write down what came in, what it cost you, and what was left over, and you add it to a running total. It sounds almost too basic to matter, but most people never do it, which is exactly why they cannot say with confidence whether they are closer to their goal or further away. You can, every single week, because it is written down.
Alongside the P&L, you will pick one KPI — one number, besides gross profit, that tells you the most about whether your business is healthy this week. It might be new customers, repeat buyers, or something specific to your offer. One number, tracked every week, beats ten numbers tracked occasionally, because you can actually act on one number.
Your cumulative gross profit is exactly what the Grow gate measures, added up week over week, all the way from week one.
Use Claude to help you set up the P&L structure and think through which KPI actually fits your business — not to invent numbers for you. Your real revenue and costs have to come from your own records.
I'm setting up a weekly P&L for the Grow stage of Make First. Gross profit is money in, minus what it cost to make and sell. Here's what I know so far about my revenue and costs: [describe or paste what you have].
Help me organize this into a simple weekly P&L structure with revenue, costs, gross profit, and a running cumulative total — don't invent numbers I haven't given you. Then ask me questions to help me choose one KPI to track weekly: what matters most for my specific offer, and why. Push back if I try to pick more than one number. Make
