Even the most seasoned merchandising teams struggle to balance over-assortment and under-assortment. Why is this so prevalent? Because these issues go beyond inventory management. It’s the upstream, strategic decisions—from product line planning to real-time collaboration—that determine whether you overbuy or miss out on your most profitable SKUs.
This post breaks down why over/under assortment persists and offers actionable steps to help retail leaders improve sell-through, protect brand equity, and stay ahead of demand shifts.
Common Misconceptions About Over/Under Assortment
“It’s Just an Inventory Problem.”
- Reality: If your line plan is misaligned with customer demand, no amount of last-minute forecasting or warehousing tactics can fix systemic overbuying or underbuying.
“A Spreadsheet Can Solve Everything.”
- Reality: Static spreadsheets and siloed data can’t keep up with today’s fast-paced market. Merchandising leaders need real-time visibility and collaborative tools to adapt quickly.
“Markdowns Are a Necessary Evil.”
- Reality: While some discounting is inevitable, heavy reliance on markdowns signals upstream misalignment. Brands that tackle the root causes see fewer markdowns and stronger brand positioning.
Early Decisions: Where Over/Under Assortment Problems Begin
- Line Planning & Product Conception
- A data-informed vision is key. Analyzing historical sales and emerging consumer trends reveals which categories warrant deeper buys—and which may be too risky.
- Collaboration Gaps Between Teams
- True alignment requires a single source of truth for design, merchandising, and supply chain. When decisions happen in a vacuum, overrepresented styles can crowd out more profitable SKUs.
- Failure to Adjust in Real Time
- Trends shift, weather changes, competitors pivot. Without real-time data, teams can’t make mid-cycle tweaks—whether it’s cutting underperforming SKUs or doubling down on emerging winners—to avoid markdowns or stockouts.
How to Fix It: Real-Time Data & Smarter Collaboration
- Adopt a Unified Digital Platform
- Why It Matters: Bringing product data, design feedback, and financial targets into one platform reduces blind spots and speeds decision-making.
- Example: According to a Bain & Company retail study (2022), moving from siloed spreadsheets to cloud-based collaboration can reduce lost sales from stock misalignment by up to 20%.
- Emphasize Data-Driven, Visual Line Reviews
- Why It Matters: Layering historical sales data, competitive insights, and in-market data into line reviews builds confidence in merchandising decisions.
- Action Tip: Establish more frequent visual reporting feedback loops throughout pre-development to catch and iteration on over/under assortment issues.
- Enable Dynamic Product Adjustments
- Why It Matters: If an early prototype gets lukewarm feedback, pivot quickly—update the color palette, adjust the price point, or drop the style.
- Result: You minimize the risk of overcommitting to low-performing SKUs and maximize potential for trending styles. A Forrester report (2023) found agile product pivoting can boost in-season sell-through by up to 15%.
