Why “more” isn’t better—and how tracking SKU movement is the key to growth, not just inventory control.
In the distribution-heavy worlds of glass, ceramics, and refractories, there’s often a belief that product breadth equals customer value. The thinking goes: if you carry everything, they’ll always come to you. But in practice, a bloated SKU count rarely translates into growth. In fact, it often does the opposite.
That’s why the best distributors are shifting their mindset from how many SKUs they carry to how fast those SKUs move—i.e., SKU velocity.
What Is SKU Velocity?
SKU velocity refers to the frequency and volume with which a specific item sells over a defined period. It helps you identify which products are truly active in the field—and which ones are just taking up space and cash.
For example, if you’re carrying 200 types of ceramic filters but only 20 of them move more than once a quarter, your real catalog is 10% of what it appears to be.
Why It Matters More Than Count
Inventory carrying cost isn’t just tied to quantity—it’s tied to time. A slow-moving zirconia tube that costs $90 per unit but sells once a year is more damaging to your balance sheet than a $20 high-alumina brick that moves weekly. Velocity identifies this drag and gives you a roadmap for action.
How to Measure It
Turns per year – Classic method: how many times did the stock rotate?
Orders per customer – Which SKUs show up in repeat orders?
Active customer reach – How many accounts have purchased this SKU in the past 6–12 months?
High-velocity SKUs are not just profitable—they’re predictable. They’re easier to forecast, easier to keep in stock, and more defensible when negotiating with suppliers.
What to Do With Low-Velocity SKUs
Not all slow movers should be cut. Some may be strategic—e.g., used in shutdown projects or seasonal applications. Others may have high margins that justify their shelf life. But those are exceptions, not rules.
Low-velocity SKUs should trigger at least one of the following:
Convert to special-order only
Bundle with high-velocity items to improve sell-through
Phase out over time while promoting alternates
Communicate Internally
Operations, sales, and procurement all need access to SKU velocity reports. When sales knows which items move and which don’t, they can adjust their pitch. When procurement knows, they can reduce reorders and improve supplier terms. And when warehouse staff knows, they can organize stock accordingly.

SKU count is vanity—velocity is sanity. For distributors in the glass, ceramics, and refractories space, focusing on SKU velocity is a strategic pivot toward growth, responsiveness, and capital efficiency. The fewer SKUs you carry with high turnover, the faster you move—not just inventory, but your business.
