SKU Rationalization for Growing Brands: Protecting Margins Without Compromising Growth

Growth brings momentum, and complexity. As brands scale, their assortments often expand with new flavors, formats and innovations. However, more SKUs don’t automatically mean more growth. In fact, expanding a portfolio too quickly can crowd the shelf, strain operations, dilute consumer focus, and erode productivity. While adding more products generates revenue, each new SKU introduces operational demands, and the cost of managing a bloated portfolio can quickly outweigh its benefits.

This is why brands should regularly assess the value of each item – not only in relation to their own lineup, but also within the competitive set. There are many reasons to gauge assortment, from removing underperforming items to innovating within categories.

Effective SKU rationalization is about creating a healthier, more intentional assortment that fuels growth. Think of it as trimming the fat without cutting the muscle.

What is SKU Rationalization?

SKU rationalization is the strategic review of a brand’s product lineup to determine which SKUs should be kept, improved, or discontinued. The goal is to create an assortment that maximizes profit, eliminates underperformers, and supports innovation.

At its core, the process helps brands answer three questions:

1.     Does this SKU contribute to growth?

2.     Does it serve a distinct consumer need or shopper group?

3.     Is it financially and operationally efficient to keep it?

For scaling businesses, SKU rationalization is not a one‑time exercise, rather an ongoing discipline that ensures the portfolio evolves with consumer demand and operational realities.

How Growing Brands Can Build a More Strategic Portfolio

Balancing Evolving Expectations with Operational Efficiency

One challenge that scaling businesses face is walking the fine line between operational efficiency and consumer demand. On one hand, too many SKUs can result in lower sales and margins, as each additional item requires support, manufacturing adjustments, and inventory management.

On the other hand, consumer expectations are shifting faster than ever. Today’s shoppers are more fickle and likely to experiment with private labels or new brands. They seek products that align with specific lifestyle needs, such as health and wellness, convenience, and flavor exploration, among other considerations.  

If businesses, including small and medium-sized businesses (SMBs) focus only on their most efficient, core SKUs, they risk becoming outdated in a dynamic environment. A company might save money operationally but could lose relevance with consumers who are looking for the next big thing. The goal is to identify which core SKUs earn their keep while leaving room for the innovation that captures new buyers.

The Importance of Playing to Your Strengths

Speed is an important advantage that growing brands have compared to CPG conglomerates. While a large global brand might take 18 months to bring an innovation to market, smaller and more agile businesses can often retool and launch in as little as six months.

This speed is a superpower. Retailers are increasingly looking to emerging brands to fill innovation gaps that larger partners can't address quickly enough.

To strike the right balance, these brands must protect their ability to innovate. Instead of blindly cutting low-volume SKUs, SMBs can use insights to determine whether a product has potential for a future trend or is truly a low performer that requires reevaluation and possible removal.

Strategies to Prioritize High-Performing SKUs

Rationalizing a portfolio requires a framework centered on the concepts of “grow, modify, or discontinue.” To do this effectively without compromising the health of the overall portfolio, high-potential brands need to look beyond raw sales data and leverage robust insights into performance, the competitive landscape, consumer sentiments, and omnichannel behaviors.

1)    Analyze consumer value, not just price

As modern brands know, value isn't always about the lowest price. It’s about the role a product plays in the consumer's life.  A niche product might have lower velocity than a core item, but if it attracts a highly loyal shopper who builds a large basket around it, that SKU is critical.H4: Consider the "Attainable Splurge"

Despite ongoing macroeconomic pressures, shoppers have demonstrated that they are still willing to spend on attainable splurges. For instance, a consumer might cut back on big-ticket items but will happily pay $12 for a viral chocolate bar or premium wellness drink because it aligns with their self-image. Rationalization shouldn't mean removing premium or niche items if they serve this psychological need.

2)    Identify transferable demand vs. incrementality

Understanding if a product is distinctive enough is a technical but vital part of the SKU rationalization process. This involves understanding transferable demand and incrementality.

• Transferable demand: If you delete Product A, will the shopper simply buy Product B instead? If yes, you can safely rationalize Product A without losing revenue.

• True incrementality: If you delete Product A, does the shopper leave your brand entirely? If yes, that SKU is incremental and should likely stay.

How to Use Data to Drive Decisions

As creative and agile as emerging and midmarket brands are, they need data to effectively guide their lineup. Circana’s Liquid Data Go™ solution levels the playing field for SMBs as they evaluate their portfolios.

Liquid Data Go provides scaling businesses with access to the same caliber of consumer insights that global giants use. It allows them to:

• Track consumer behavior: Understand who is buying your product, how often, and what else is in their basket.

• Audit your portfolio: Evaluate categories and products by their role, i.e., core vs. innovation.

• Test concepts with Surveys: Validate a new SKU before adding it to the collection. For example, protein may be a major trend right now, but is a protein-based or protein-enhanced product right for your brand and category? Importantly, are consumers willing to pay more for it?

• Evaluate assumptions: Use consumer data to verify if low-volume SKUs are actually driving loyalty.

• Monitor trends: Identify what is driving excitement on social media and pivot your portfolio to match.

Scaling brands often operate with leaner teams, making efficient data analysis critical. By using tools that track shopper behavior and retail trends, growing brands can ensure that their SKUs drive incrementality and protect margins rather than linger on or clutter the shelf.
