A 20% Discount Costs You 50% Of Your Profit
Revenue is an amplifier.
It doesn't create the health of your business. It multiplies whatever health is already there.
Strong margin, and every extra dollar of revenue compounds into profit.
Loose margin, and every extra dollar of revenue compounds the problem.
Which is why you can't grow your way out of a margin problem. You only ever grow into a bigger one.
That's the trap I walked into in 2019 - the year I crossed $10 million in revenue and lost over $200,000. The margins were loose and I wasn't watching. So when the revenue doubled, all it did was double the leak. If you missed that email, you can read it here.
So before you chase more volume, the margin underneath it has to be right.
Here's the first shift…
Margin is a decision, not a leftover.
The common approach is to price against what feels acceptable, or what a competitor charges, or what you think the customer will tolerate. Then whatever profit remains at the end of the month is your margin.
That's backwards.
You decide the margin the business needs to be healthy. Then you build the pricing and the cost structure to deliver it.
One is a number you discover. The other is a number you set.
Only one of those is a business.
Now here's the piece of maths that should change how you think about discounting.
Say you sell something for $100. It costs you $60 to produce and deliver. That's $40 of gross profit, at a 40% margin.
Now you run a 20% discount.
You've dropped $20 off the price. But your costs haven't moved. So your gross profit falls from $40 to $20.
You didn't just lose 20%. You lost 50% of your gross profit.
And to make the same total profit you were making before in real dollar terms, you now need to sell double the number of units.
Not 20% more. Double.
More orders. More packing. More support. More freight. More stock tied up. All of it to end up exactly where you started.
And it gets worse the thinner your margin gets.
At a 30% margin, that same 20% discount wipes out 75% of your gross profit, and you'd need to sell triple as many units just to break even on the decision.
Which is the cruel part. The businesses least able to afford a discount are usually the ones running them most often.
And it applies in reverse too.
When a supplier raises their prices 5% and you absorb it rather than adjusting your own, that's not just a 5% problem. That's the beginning of the erosion of your margin.
Which brings me to the thing that quietly kills margin.
It's never one decision.
It's a discount to close a deal.
A supplier increase that you absorb.
A product line you add at a lower margin because the incremental revenue looks good.
A customer you give special terms to because they are difficult.
Every one of those is defensible on its own.
Together, they've moved you from 58% to 44% over eighteen months, and nobody noticed, because nobody was measuring it as a percentage month over month.
That's why the P&L work matters. Margin erosion is almost invisible in dollars and obvious in percentages.
And here's what you're actually protecting...
Margin isn't just profit. It's options.
Margin is what enables you to pay for better people.
It's what lets you absorb a bad quarter without panicking.
It's what lets you invest in the product instead of stripping it back.
It's what lets you outspend competitors to acquire a new customer, because you can afford to.
Thin margin removes every one of those.
Everything becomes urgent.
Every decision gets made under pressure.
You lose the ability to play a long game because you're solving for this month.
So the question isn't just "how do I sell more."
The question is "what does every extra sale actually earn me, and is that number strong enough to be worth chasing."
Because volume on a weak margin is just a more expensive way to go backwards.
Protect the margin first.
Then go get the volume.
