Key Takeaways:
- Retail portfolio strategy: 15–20% of SKUs drive 70–80% of revenue, making hero product concentration a financial risk.
- Expanding beyond a bestseller reduces revenue volatility; brands like Kraus Jeans and KRVVY cut top-SKU dependence by adding adjacent products tied to the same customer need.
- Successful product portfolio expansion starts with small test runs, live sell-through data and scaling only what shows traction.
- For retail buyers, portfolio depth supports larger basket sizes, repeat purchases and more stable open-to-buy decisions.
The Case for Building Beyond the Bestseller
Retailers are moving past the single bestseller and building broader product portfolios designed for steadier growth. The pattern is clear in fashion and direct-to-consumer: one distinctive item can generate awareness, but a wider range drives repeat purchases, bigger baskets and less volatile revenue.
A small share of SKUs typically drive most sales. Multiple industry sources put the split at roughly 15 to 20 percent of products accounting for 70 to 80 percent of revenue. A hero product simplifies merchandising, reduces marketing complexity and can generate word of mouth that paid media struggles to match. The risk is concentration. If consumer taste shifts or supply misses, there’s little room to adjust.
The answer isn’t to abandon the hero. It’s to build around it. Kraus Jeans trimmed the revenue share of its top styles from about 65 percent to roughly half by adding baby tees, denim shirts, flat-knit tops and athleisure. Shapewear brand KRVVY saw its top sellers’ revenue mix fall from close to 80 percent to around 60 percent within a few months. In both cases, extensions stayed close to the core. A denim buyer often wants relaxed knits and everyday layers. A shapewear customer may want base layers that serve the same body need. The link stays clear, and shoppers get a reason to return.
Why Is the Second Product So Hard to Get Right?
The second product is the hardest test because it must win current customers without confusing them or diluting the core. A practical rule: solve a neighboring need, not just add a neighboring product. That keeps the connection obvious while giving buyers something different to explore.
Done well, a wider range raises average order value, unlocks bundles and seasonal campaigns, and creates more paths to repeat purchase. In crowded marketplaces and paid media auctions, that depth can turn a one-off transaction into a growing customer file.
How Are Retailers Reducing the Risk of Getting It Wrong?
Many brands are managing portfolio risk by starting smaller. Limited first runs, close performance tracking and scaling only what shows traction can replace guesswork with evidence. In fashion especially, where color, cut and timing can turn a sure bet into a markdown in weeks, a small initial order limits exposure while a tight replenishment loop lets a real hit build momentum.
Faster data makes this approach viable. Live sales dashboards, POS feeds, marketplace analytics and connected merchandising systems show how products perform across regions and channels within days of launch, not at season close. Performance varies by channel. One marketplace may reward a sharper price. Another may respond to a specific search term. A brand’s own site may attract customers who favor more premium or distinctive items. Reading those differences helps teams adjust inventory, creative and pricing accurately.
For retail buyers, the portfolio approach offers clear tactics: ask for adjacency logic that ties new items to the core, use small test buys to confirm turn before committing volume, watch live sell-through by channel and shift open-to-buy toward proven winners. Pair heroes with dependable add-ons to grow basket size and keep inventory risk tight on new colorways and seasonal bets.
For brands, a steady pipeline matters as much as the next viral SKU. Protect hero inventory, build a calendar that introduces credible follow-ons and design post-purchase programs that guide customers to the next logical product. Treat the first production run as a test, the next two as scale and measure success by contribution margin and cash conversion, not just revenue spikes.
A hero product powers acquisition and cash flow. A balanced portfolio diversifies risk, grows lifetime value and sustains momentum. Brands that last keep the engine running, test with discipline and develop the next useful thing before the last one peaks.
