Revenue Is a Terrible Scoreboard

Imagine two card shops. Last month, Shop A sold $100,000 worth of cards. Shop B sold $60,000. Which business would you rather own?

You don’t know. That’s the only responsible answer.

You don’t know what either shop paid for its inventory. You don’t know how much went to marketplace fees, or whether they paid to promote those listings, or how many employees it took to process the cards, or whether the sales happened online, in-store, at shows, or through direct deals. You don’t know whether Shop A made $30,000 or $3,000. You don’t even know whether it made money.

Yet we do this all the time in the card business. We use sales as a shorthand for success. Someone is a “$1 million seller.” A shop “does $5 million a year.” A dealer “did $80,000 at the show.” Those numbers sound impressive because they’re big, easy to understand, and easy to compare. They’re also incomplete.

The million-dollar card business

Let’s build one. We’ll keep the math deliberately simple. Our hypothetical seller does exactly $1 million in annual card sales: about $83,000 a month. From the outside, this looks like a serious operation. Maybe there’s a shop, a few employees, a large eBay account, tables at major shows, new collections coming through the door constantly.

Let’s say this seller generally acquires inventory for around 70% of what they expect to sell it for.

The exact numbers aren’t the point. Change any of them you want. The point is that $1 million tells us almost nothing about the quality of the business that produced it. Accounting works this way for a reason: revenue and expenses eventually have to meet before you arrive at income. This isn’t advanced finance. It’s subtraction. But it’s subtraction we conveniently stop doing when the first number makes us feel good.

Big numbers are seductive

I understand why. Revenue is fun. Profit is messy. Revenue goes up and to the right. Revenue makes a good Instagram post. You can tell someone at a show, “We did $100,000 last month,” and they immediately understand that your business has some scale. Try saying, “We generated $27,400 in contribution margin before fixed operating expenses.” Congratulations. You’ve ended the conversation.

Revenue is also visible. You can watch sales happen. Your phone makes a noise. Orders pile up. Employees get busy. Packages leave the building. Money hits the account. Activity feels like progress. And when sales increase, activity increases with it. This creates one of the easiest traps to fall into as an operator: busy feels like growing. Sometimes it is. Sometimes you’re just doing more work.

Revenue tells you how much money passed through the business. It doesn’t tell you how much stayed.

Would you like another $100,000 in sales?

This is where revenue becomes dangerous. Suppose your business is doing $500,000 a year. I offer you another $100,000 in annual sales. Do you want it? Of course. Except I haven’t told you anything about the sales.

What if you need to spend $85,000 acquiring the inventory? What if the channel takes another $12,000? Now you’ve generated $100,000 in revenue and have $3,000 left. Still want it? Three thousand dollars is three thousand dollars, so probably. Except processing the additional inventory requires ten hours of employee labor every week. Now we’re in a different conversation.

If those additional sales create customers who come back for higher-margin inventory, different conversation again. If the inventory turns in three days and you redeploy the same capital over and over, now it’s genuinely interesting. If it takes eighteen months to sell, it isn’t.

The real question is what it takes to produce that $100,000, and what you get to keep when it’s over. That’s a completely different question, and it’s the only one worth asking.
