Your Cost Sheet is Lying to You

The real cost of a garment isn't the factory invoice. It's the invoice plus every markdown you haven't taken yet.

Ask most apparel operators what a garment costs, and they'll point at the invoice. Ten dollars a unit, landed. Clean number, easy to plan around.

It's also the wrong one.

The invoice tells you what it costs to make the product. It says nothing about what it costs to sell it - ie to get it off the rack and into a consumer’s hands. And in apparel, that second number is usually the one that decides whether you made money.

So what actually gives you the full picture of the cost of a garment?

How much of it you sell at full price.

Here's the math the cost sheet hides:

Say a style costs $10 a unit to make and retails at $50. Produce 1,000 of them. If all 1,000 sell at full price, the economics are beautiful. But you almost never sell all 1,000 at full price.

So say 600 sell at $50, and to clear the last 400 you drop the price to $25. Your revenue isn't 1,000 × $50 = $50,000. It's (600 × $50) + (400 × $25) = $40,000. You still spent $10,000 to make the goods — but you also handed $10,000 of potential revenue back in discounts to move the part of the buy you never should have committed to.

That $10,000 is a cost. It's just an invisible one. But another $10 per unit ($10,000 of markdowns split over 1,000 units) isn’t something a brand should hide from itself. It’s real. It doesn't appear on the invoice, and it doesn't appear until months after you placed the order when you’re heavily discounting to move goods at the end of the season. Even then, accountants hide this cost “above the line.” But the cost is real.

The $10 / unit you saw on the factory invoice ended up being double what you thought.

The invoice is the visible half of your cost. The markdown is the hidden half — and the hidden half is the one you can't see at the moment you commit, which is exactly what makes it dangerous.

This hidden cost is a symptom of overbuying. Overbuying is common in apparel, as brands see stockouts as a bigger risk than markdowns. But that is not the same thing as saying that overbuying is optimal. We assert that overbuying is not necessary if brands leave behind the antiquated supply chain practices that gave rise this cash-hungry business model in the first place.

If the markdown is the real cost, then squeezing the factory for a lower unit cost is only one way to bring down cost. And if anything, it’s probably already squeezed out. The other half of the cost equation is to stop buying the units you'll later have to discount.

That's what an agile supply chain does. Instead of committing to one giant order months in advance, you commit small test buys, read real demand, and chase into what's actually selling. Shorter production cycles — weeks instead of months — mean you're producing close to the moment of sale, when you finally know what the customer wants instead of guessing.

Yes, a smaller buy costs a little more per unit. Less scale, less leverage over the factory. But you're trading a few points of unit cost for a collapse in the markdown bill. On a true-cost basis, the "more expensive" unit is very often the cheaper decision.

Whether the markdown reduction more than offsets the higher unit cost depends largely on if the factory partner is “agile.” Two key tests we apply for whether a factory can be counted as “agile”: 1) The factory understands the “how” of cost-effective low MOQ production, and 2) the total PO-to-Fulfillment lead time is no longer than 6 weeks.

If the factory passes these crucial tests (as all Patchwork factories do), then the lower markdowns completely dominate the effect of the (slightly) higher cost per unit.

And lower markdowns are only the first payoff.

The same agility that lowers your markdowns lifts your revenue from the other direction. When you can chase, you don't just avoid the duds — you get to feed the winners, IN-SEASON. A style takes off, you make more of it and get it to the consumer while demand is still hot, instead of stocking out and watching the moment pass.

And because you're committing less up front, you can afford to carry more newness: more styles, more tests, more shots at the next hit. A fresh, relevant assortment sells at full price. A stale one goes on sale.

The third payoff shows up on the balance sheet. Every dollar committed to inventory is a dollar frozen — sitting in a container, a warehouse, or on a shelf, doing nothing else. Buy tighter and you thaw that capital. Instead of financing a pile of goods you're hoping to sell, you can put the money into the things that actually compound: stores, marketing, product, people. The brands that aren't over-committed to inventory get to fund their own growth.

Lower markdowns, more full-price revenue, and freed-up capital. Agility pays off 3 different ways at once.

Aritzia learned this in public.

Coming out of the pandemic, the Everyday Luxury brand could do no wrong — the stock had more than tripled and US demand was surging. Then, in 2023, inventory piled up. Faster lead times and better freight pulled a wave of product in earlier than planned, too much of it repeating what had already sold, and the cost of warehousing all of it started eating margin. A stale, overbought assortment doesn't move at full price, so the markdowns came. Inventory ran near triple the prior year, the company posted a net loss, comparable sales swung from up 28% to down 4%, and the stock fell 24% in a single day, down roughly 50% on the year.

CEO Jennifer Wong didn't discount her way out. She held the line on full price, put newness back into the assortment, and returned to buying tight and close to demand — while, against loud skepticism, continuing to invest in stores and capacity straight through the slump.

For about a year she looked wrong. Then the discipline compounded: fiscal 2026 revenue hit a record $3.7 billion, up 35%, profit grew 84% — more than double the pace of sales — and the company reached its 2027 revenue target a full year early.

The clothes never got cheaper to make. Aritzia just stopped buying the units it would end up giving away at the end of the season.

And Aritzia isn't alone: Abercrombie's read-and-react turnaround under Fran Horowitz was largely the same lesson. And smaller agile brands like Gym Shark, Fashion Nova, and Oh Polly are running this playbook with breathtaking success.

We present three takeaways from the hidden half of the cost sheet.

#1 Your true unit cost includes a markdown you haven't taken yet

Plan on landed cost plus expected markdown, not the invoice. A style that costs $10 to make but moves 40% of the run at half price never really cost $10. Build the discount into the number before you commit, or you're flying blind on your own margin.

Compare true cost, not sticker COGS.

#2 Agility pays off 3 ways at once:

Speed isn't just a margin trick. Buying tight and close to demand does lower your markdowns and protect margin — but it also grows revenue by allowing you to chase best-sellers + find new hit styles faster through flexible testing. And there’s a third benefit: it frees the capital you'd otherwise freeze in a speculative buy. Capital is the “margin of safety” on your business: you never know when you need it. And you don’t want it stuck on a boat or warehouse somewhere when you do need it. But capital isn’t just defensive, which brings us to point 3…

#3 The inventory you don't buy is your cheapest growth capital

Money frozen in a speculative buy can't open a store, fund a campaign, or make a new style. Agile production isn't only a margin or revenue play, it's a financing decision. The working capital you free up is growth you can fund yourself, without handing anything back to the discount rack, or giving equity away to an investor.

One of our longest tenured brands - Tradlands - saw all 3 of these benefits in action when they grew profits 146% in the first year working with Patchwork.

In fashion, design may be what grabs the headlines. But its supply chain that drives the business forward or backwards.

Patchwork is an agile supply chain platform for apparel brands. We help brands move from large speculative production bets to demand-responsive production — reducing inventory risk and deadstock.
