Know your numbers
You can't improve what you don't measure. You can't profit from what you don't track.
Most sellers track revenue and nothing else. They don't know their true costs, their margins, their customer acquisition numbers, or whether they're actually profitable after all expenses. This lesson builds the complete financial tracking system for digital product sellers. Profit isn't what's left after revenue. Profit is what's left after you know your numbers.
What goes wrong
- You track revenue but not profit — you think you're doing well when you're barely breaking even.
- You don't know your customer acquisition cost — so you can't tell if your marketing is working.
- You have no unit economics — you don't know what each sale actually costs you.
- You can't calculate lifetime value — so you don't know how much you can afford to spend on acquisition.
- You're flying blind on margins — platform fees, processing fees, refunds, and overheads are a blur.
- You make decisions based on feelings instead of data — and your profitability suffers.
What the profit numbers system does
- A complete profitability framework — revenue, costs, margins, and true profit for every product.
- Customer acquisition cost tracking — know exactly what it costs to acquire a customer through every channel.
- Unit economics calculator — the per-sale numbers that tell you if your model actually works.
- Lifetime value measurement — how to calculate, track, and increase LTV for every customer cohort.
- Margin analysis tools — fee tracking, cost allocation, and profitability reports for every product.
- A data-driven decision framework — what to measure, when to act, and how to improve.

Inside the method
What the profit numbers system actually covers
Eight modules that build your financial tracking system from basic revenue to full profitability analysis. Follow them in order.
How to track revenue accurately across multiple products, platforms, and payment processors. The difference between gross revenue, net revenue, and recognised revenue.
Every cost your business has, categorised and allocated correctly. Platform fees, payment processing, tools and subscriptions, marketing spend, contractor costs, and overheads.
The per-sale numbers that reveal whether your business model works. Average order value, cost per sale, contribution margin, and break-even analysis for every product.
How to calculate CAC for every channel — organic, paid, referral, email — and use it to make marketing investment decisions. The framework for reducing CAC over time.
How to calculate, track, and increase customer lifetime value. LTV by cohort, by product, by channel, and the LTV:CAC ratio that determines your business health.
How to run margin analysis by product, by channel, by customer segment. The profitability report template that shows you exactly where you make and lose money.
Why cash flow matters even for digital products. How to manage timing differences between revenue, expenses, and payouts — and avoid cash crunches.
How to use your numbers to make better decisions. What metrics to watch weekly, monthly, and quarterly. When to invest, when to cut, and how to know the difference.
When you've finished
You won't guess your profitability. You'll know it, down to the decimal.
This lesson is designed to produce a complete profit tracking system. Complete the files and you should have all six outcomes.
- A complete revenue and cost tracking system for your business.
- Unit economics calculated for every product you sell.
- Customer acquisition cost by channel, with optimisation targets.
- Lifetime value tracking by cohort, product and channel.
- A profitability report showing exactly where you make and lose money.
- A data-driven decision framework for growing your business profitably.
Honest fit check
$7 is cheap. Knowing your real profit margin isn't.

Before you buy
Quick answers
Do I need an accounting background to use this?
No — the system is designed for non-accountants. Everything is explained in plain language with worked examples. If you can add, subtract, multiply and divide, you can use this system. The templates do the heavy lifting.
Will this work for any type of digital product?
Yes — the framework works for ebooks, courses, templates, software, memberships, coaching, and any other digital product. The metrics are universal; only the specific costs vary by product type.
I'm a solo creator. Is this overkill?
No — solo creators need this most. Revenue hides problems that kill small businesses. A simple tracking system prevents you from scaling a business that isn't actually profitable. The system scales from solo to team.
Can I use this for client work?
Yes — you can use and customise the material for your own business or for client financial tracking projects. What you can't do is resell or redistribute the files themselves as a product.
Should I just buy the whole stream instead?
If you expect to want more than three lessons, yes — Stream 03 is $24 for all twelve, and it includes the Toolkit. Start here if you'd rather see one lesson first.
How long to get the tracking system set up?
Revenue and cost tracking setup takes 1-2 days. Unit economics and CAC calculations take another day. LTV and margin analysis requires some data history but can be estimated initially. You can have a basic system running in 3-5 days.
