The danger of duplication—how SKU overlap silently eats into margins, space, and service speed.
In glass distribution, more options are often seen as a customer service advantage. Whether you’re supplying tempered safety glass, insulated glazing units, or laminated panels, variety can feel like a competitive strength. But there’s a fine line between offering variety and overcomplicating your product mix. And that line is where duplicate SKUs begin to quietly sabotage profitability.
Let’s say you offer three slightly different low-E coated glass panels—each with minor variations in emissivity and tint. One is from your domestic supplier, another is from a European brand with premium marketing, and the third was onboarded years ago for a single project that’s long since wrapped. Despite their technical differences, all three serve the same core customer need: energy-efficient glazing. If you’re still stocking all of them, you’re likely cannibalizing your own inventory.
Glass distributors across the U.S. and Canada increasingly find themselves in this trap. New SKUs get added for project-specific specs, client preferences, or because of short-term sourcing issues. But without a rigorous review process, those SKUs linger. The result? Inventory redundancy, inflated carrying costs, forecasting complexity, and warehouse confusion.
How can you tell if you’re carrying too many versions of the same thing? Here are key indicators:
Sales Dilution Across SKUs: If you have five types of annealed float glass in 6mm thickness and none moves more than 20 sheets per month, you’re likely fragmenting demand unnecessarily.
Customer Indifference to Differentiation: Are clients asking for a specific low-iron variant, or are they just asking for “clear glass”? If they don’t notice the difference, they won’t miss the consolidation.
Procurement Fragmentation: Ordering small volumes from multiple vendors for similar products hurts your buying power. Volume consolidation leads to better terms and smoother lead times.
High Mis-pick Rates: Overlapping SKUs confuse warehouse teams. If pickers frequently grab the wrong version of a 72″x84″ tempered lite because two near-identical ones sit side-by-side, it’s a red flag.
Consolidation doesn’t mean cutting corners—it means refining the catalog to focus on SKUs that serve the most customers with the fewest complications. One East Coast distributor recently reviewed its IGU portfolio and found it was offering four edge spacer color options, two of which hadn’t been selected in over a year. Consolidating down to two not only simplified production but also cut supplier lead times by 30%.
It’s not just about the warehouse either. Sales teams benefit from a more focused product range. Too many overlapping options create decision fatigue for reps and clients alike. If you’re explaining the subtle differences between three heat-soak-tested products to a customer who’s just asking for “tempered glass with quick delivery,” the conversation is already off track.

Glass distributors who streamline overlapping SKUs aren’t shrinking their value—they’re sharpening it. In a business where space, speed, and service matter, every redundant product comes at a cost. Reviewing and reducing duplication isn’t about selling less—it’s about selling smarter. And when done right, fewer SKUs can lead to more confident sales, better margins, and faster fulfillment.
