Special orders can grow your business—if you know when to standardize them.
Distributors of architectural and industrial glass often live in the gray space between standard products and custom requirements. Every week brings a request that doesn’t quite match what’s on the shelf—oversize insulated units, triple-laminated panels with custom interlayers, low-E coatings for marine environments. The question isn’t whether to fulfill these requests. The question is whether to formalize them into new SKUs.
New SKUs carry cost: catalog complexity, inventory planning, procurement timelines, and potential obsolescence. But custom SKUs also drive value when created thoughtfully. The trick is knowing the difference between a one-off request and an emerging product trend.
Here’s how seasoned distributors decide when to create new SKUs:
Volume Justifies Complexity
If a custom order repeats three or more times in a quarter, that’s a signal to assign a dedicated SKU. Especially if the product uses consistent specs—e.g., 6mm laminated low-iron glass for railing infills—it’s worth codifying in your ERP.
Client Relationship Significance
For key accounts like high-volume residential window manufacturers, dedicating a SKU to their unique specifications (e.g., IGUs with specific spacer colors or gas fills) shows commitment and simplifies reorders. It also tightens integration between your ops and theirs.
Operational Reproducibility
Ask: Can your team reproduce the item consistently with the same vendors and quality checks? If yes, SKU it. If it requires constant engineering input or supplier sourcing, keep it project-specific.
Trend Alignment
Is the custom request part of a broader market trend—like a surge in triple-glazed units for passive house builds? If so, it may become a core product in your future line.
Supplier Support
If your suppliers can offer price breaks or better lead times on larger runs of a new variant, creating a SKU could unlock better economics for both parties.
Material Commitment
Does fulfilling the custom glass spec require unique raw materials or coatings? If so, you’ll need to decide if it’s worth stocking those inputs or if the item should remain built-to-order.
When not to create a new SKU:
For highly irregular shapes or specs used in one-off architectural projects.
For items with uncertain supply chains (e.g., custom-tinted interlayers sourced internationally).
When the lead time or MOQ doesn’t support repeat business.
Instead, use job-based tracking—assign a project ID, not a SKU. That way, your ERP doesn’t get cluttered, but your team can still reference past work and quote faster.

New SKUs are valuable tools—but only when they’re backed by repeat demand, supplier alignment, and operational readiness. For glass distributors, formalizing custom products can open doors to bigger accounts and long-term relationships. But each SKU should earn its place. Treat them like assets, not favors.
