On average, just 15-20% of a brand's SKUs generate nearly 70-80% of sales, according to an Apparel Resources analysis examining how apparel businesses structure their product mix. That concentration makes hero products the backbone of merchandising, inventory planning and marketing across the industry.

The analysis, published by Apparel Resources under the title "From Hero Product to Hero Portfolio: The Shift Beyond the Bestseller," frames the issue in operational terms. A hero product does exactly what it is supposed to do: it attracts customers and drives the bulk of sales. But the piece argues that while hero products continue to play a crucial role, the strategy built around a single bestseller carries structural risks for brands and their sourcing partners.

For sourcing and supply-chain professionals, the numbers frame familiar decisions. When four-fifths of revenue rides on a fifth of the range, factories face lopsided capacity commitments, planners concentrate open-to-buy around few styles, and markdown exposure concentrates when a bestseller fades.

What does SKU concentration mean for planning?

The 15-20% figure gives merchandisers a benchmark. Brands can measure their own concentration against it and stress-test what happens if one hero SKU underperforms. The analysis positions inventory planning as one of three functions, alongside merchandising and marketing, that depend directly on hero product performance.

Why shift from one hero to a portfolio?

The article's core argument is the move from a single hero product to a "hero portfolio" — a deliberate spread of high-performing SKUs rather than reliance on one bestseller. This is where the commercial logic sits for vendors. A portfolio approach distributes production volumes across multiple styles and potentially multiple factories, softening the impact when demand shifts.

Apparel Resources does not present the shift as a rejection of bestsellers. Hero products continue to play a crucial role, the analysis states. The proposal is to build resilience around them rather than bet the season on them.

What should brands and vendors watch?

The analysis points to several operational implications for supply-chain decisions:

• Merchandising: assess how much of the current range falls inside the hero SKU band and whether that band is one product or several.
• Inventory planning: concentration at 70-80% of sales means forecast error on a single SKU has outsized working-capital consequences.
• Marketing: spend allocation currently follows the same narrow set of products, reinforcing concentration rather than diversifying demand.

The piece treats these three functions — merchandising, inventory planning and marketing — as the operational core that a portfolio strategy must rebalance together, not separately.

The full analysis is available on Apparel Resources, which indicates it will detail how brands can identify and develop additional hero candidates from within the existing assortment rather than depending on a single title-holder.
