The 3 Margin Framework™: Why One Margin Was Never Enough

Here's why.

Room for Error. Nobody runs a business without making mistakes. A pricing decision that didn't land. A hire that didn't work out. A supplier who let you down. Margin isn't there because you're bad at business. It's there because you're human.

Room for the Unknown. Nobody can predict the future perfectly. Interest rates move. A key client leaves. A once-in-a-decade event shows up uninvited. Margin is what lets you absorb the shock instead of being knocked over by it.

Room for Opportunity. Nobody knows exactly when opportunity is going to show up. A chance to buy out a competitor. A client who wants to triple their order. A good hire who becomes available. If there's no margin, there's no room to say yes.

Run a business with no margin in any of these three places, and you're not running a business. You're running on empty. That's where exhaustion lives. And exhaustion never makes for a great business experience — for you or for anyone around you.

Why 3 Margins, Not Just Gross Margin? Gross margin has been around for years. So why isn't it enough anymore?

Because business has evolved. Margin isn't a single number sitting on one line of a spreadsheet. It needs to exist in several places at once — otherwise a business can look fine on paper and still be quietly running itself into the ground.

That's the thinking behind the 3 Margin Framework™: Customer Margin, Profit Margin, and Cash Flow Margin — 20%, 10%, and 5% of revenue.

Customer Margin — The Foundation (20%) If you've read my article reframing the P&L as a Customer Value Statement, you'll know where this starts.

Customer Margin is a record of the commercial value a business has actually derived from interacting with its clients. It's not just "revenue minus the cost of the product." That's too narrow.

Interacting with a customer draws on all 3 Ps — Product, People, and Promotion. Get the product to them. Have the right people to deliver it, including a fair wage and superannuation for the business owner, not just the staff. Get the promotion right so the customer finds you in the first place. Customer Margin is what's left once all three are accounted for — and a healthy Customer Margin sits around 20% of revenue.

This is the basic building block of business. If it's broken, nothing above it can be fixed. A business with no Customer Margin doesn't get to thrive. At best, it survives.

Profit Margin — What's Left After Everything Else (10%) On the page, Profit Margin sits below Customer Margin. That's not just layout. That's the story.

The gap between the two — the drop from 20% down to 10% — is everything else the business carries. Rent. Insurance. Admin. Software subscriptions. Compliance. All the overhead that isn't tied directly to serving a customer, but still has to be paid for.

Here's where it gets interesting: you can have a healthy Customer Margin and a weak Profit Margin at the same time. Two businesses can both hit 20% at the customer level and land in completely different places by the time Profit Margin is calculated. Why?

1. Too much overhead. The business is carrying more fixed cost than its revenue can support — a bigger office than it needs, more software than it uses, layers of admin that don't earn their keep.

2. Not enough volume. The overhead itself might be reasonable, but there simply isn't enough sales volume moving through the business to absorb it. The same fixed costs spread over more revenue would produce a healthy result. Spread over too little, they eat the margin alive.

Getting these two right — overhead sized to the business, and enough volume moving through it — is key to a sound Profit Margin.

Richard Chen, Director of Rich Harvest Digital, is a good example of why this matters even when a business looks fine. His business was already in a healthy state — but walking through the 3 Margin Framework surfaced areas where he was under-investing in some places and over-investing in others. A few targeted adjustments later, the business was in better shape than before. What he didn't expect was the flow-on effect beyond the numbers: better habits and routines, more breathing space, a more balanced business — not just a more profitable one.

That's what Profit Margin is for. It doesn't just tell you if you're making money. It tells you whether the shape of your cost base actually matches the size of your business.

Cash Flow Margin — The Business Wealth Statement (5%) Cash Flow Margin builds on the same reframe I've written about before — turning the Balance Sheet into a Business Wealth Statement. The benchmark here is 5% of annualised revenue.

A Balance Sheet reads like a list of pluses and minuses. A Business Wealth Statement asks a different question: is this business actually building wealth, or just moving numbers around?

Samantha Jansen, who runs Samantha Jansen Publishing, knows this one well. It started over coffee — she told me about the frustrations of delayed client payments and the stress that comes with them. With many of her authors on structured payment plans, healthy cash flow isn't a nice-to-have for her business. It's critical. We reviewed her Xero file, and it was clear where the gaps were. Twelve months on, her invoicing, pricing structure, and payment processes have all been refined. She now has real cash flow visibility and confidence in where the business is heading — not just relief that the bank balance looks okay this week.

That's Cash Flow Margin. Not a number that goes up. A business that knows, with confidence, where it's actually heading.

Together Three margins. Three different places where a business needs room to breathe. 20% at the customer level. 10% once everything else is accounted for. 5% in cash flow, annualised.

Miss one, and the other two can't save you.
