I wish someone had drilled this into my head when I first started building companies: your margins determine your destiny.
For years, I thought far more about revenue and growth than what was left over. More customers, more products, more sales. These are easy things to celebrate. Margin is less exciting until you realize it determines almost everything that comes after.
The math is obvious, which makes it all the more embarrassing that it took me so long to appreciate.
Two businesses, the same revenue
Imagine two brands that each sell $100 of product. After the variable costs of fulfilling an order, one keeps $20, the other keeps $50. Neither has paid to acquire the customer or covered its fixed costs yet.
If each spends $15 to acquire that customer, one has $5 left and the other $35. The first can barely afford to make a mistake. The second can afford to hire, build, improve, and try again. Same sales. Very different futures.
People obsess over growth rates. But the same dollar of growth is not worth the same amount to every business.
The number that actually matters
Gross margin is important, but it can be a comfortable number to hide behind. I want to know what remains after product costs, shipping, fulfillment, payment processing, returns, and other variable costs. Then subtract what it actually costs to acquire the customer.
People will tell you the customer will come back, and sometimes they're right. But LTV has a way of becoming a promise about a future you haven't earned yet.
A while ago, I had a long conversation with someone from Future Commerce about Not Pot and Jiggly. We talked about the usual things: CAC, repeat purchases, inventory, discounts, and contribution margin. What stayed with me wasn't some brilliant new growth tactic. It was how much of a company's fate was already determined by the economics of an individual order.
Margin takes time
Here's what I really wish I had understood earlier: margin is slow.
You can turn on ads and buy revenue tomorrow. You cannot rebuild an assortment, renegotiate a supply chain, improve your products, change customers' price expectations, and work through bad inventory tomorrow.
At Italic, improving our margins took years. We had to change what we sold, how we sourced it, what we charged, and how we operated. None of these was a single decision. Each took a thousand small decisions, made over a long time.
And this is the trap: low margins leave you less time to do the very work that would improve them. You spend your days managing cash, discounting inventory, and trying to make the next month work instead of building something better.
Margin isn't just profit. It's time.
What margin buys you
More margin gives you options. You can outspend a competitor for a good customer. You can survive a bad launch. You can improve the product rather than chase the next promotion. You can take a bet that might take years to pay off.
In other words, margin is what makes risk possible. That may sound paradoxical, but the best businesses can be more aggressive precisely because they don't need every decision to work.
The reverse compounds too. Thin margins lead to constant discounting to keep volume up, which makes it even harder to raise prices, which leaves you dependent on still more volume. You can grow yourself into a corner.
I still believe growth solves a lot of problems. It just doesn't solve bad unit economics. It amplifies them.
There are exceptions
There are plenty of good businesses with thin margins. Some turn inventory quickly, some have unusually strong retention, and some deliberately treat a product as customer acquisition for something else. I don't think every product needs a 70% gross margin.
But there has to be an honest explanation for where the money will eventually come from. Not a hypothetical repeat-purchase curve or the belief that scale will somehow fix everything. If you're going to subsidize something, know exactly what you're buying.
If I were starting again, I'd be just as obsessive about margin on day one as I was about growth. I'd look at it for every product and every cohort, not just in the monthly financials. And I'd ask whether the business gets more attractive or more fragile as it gets bigger.
Because the question is not how big can this become. The question is, if it becomes as big as I hope, what kind of business will I actually own?
I wish I'd learned that sooner.
Your margins determine your destiny.
