Promoting what’s popular won’t cut it. Promote what pays.
Distributors love to promote top-selling SKUs. But here’s the catch: not all bestsellers are best for the bottom line. In fact, many high-volume SKUs in glass and ceramic distribution—think ¼” clear tempered glass or standard alumina tiles—have razor-thin margins. Promoting them aggressively might move product, but it rarely grows profit.
Instead, the smartest distributors are using margin contribution to guide their promotional calendars. It’s a shift from volume-based to value-based thinking—and it changes everything.
Understanding Margin Contribution
Margin contribution is the actual dollar profit a product generates, not just its percent margin. For example:
A SKU with 10% margin that sells $100,000/month = $10,000/month contribution.
A SKU with 35% margin that sells $30,000/month = $10,500/month contribution.
The second product contributes more profit despite lower sales volume. If you’re only promoting based on velocity, you miss this nuance.
Building a Margin-Driven Promotion Strategy
Here’s how to start prioritizing promotions based on margin contribution:
Run a Contribution Analysis Across Your Catalog
Group your SKUs into quartiles based on total margin dollars. You’ll often find that 20–30% of your catalog drives 80% of gross profit.
Segment by Product Type
In glass: specialty coatings, fire-rated, or acoustic-rated panels often carry higher margins than clear float or laminated stock.
In ceramics: technical or high-purity items yield more per unit than general-purpose stock.
In refractories: proprietary shapes and monolithics outperform commodity bricks.
Assess Promotional Elasticity
Identify which high-margin products respond well to promotion. A 5% price drop on a high-margin SKU that doubles volume = major profit lift.
Bundle Strategically
Use high-demand low-margin SKUs to draw attention, then bundle with lesser-known high-margin accessories (e.g., corner trims, sealing kits, ceramic gaskets).
Push What Salespeople Undervalue
Run targeted internal contests to reward reps for promoting underutilized, high-margin items. Often, these SKUs aren’t sold because reps aren’t familiar with them.
Case Study: Ceramic Distributor in Ontario
An Ontario-based distributor of kiln furniture and technical ceramics restructured its quarterly promotions around margin contribution instead of unit sales. By focusing on their top 15 margin-contributing SKUs, including cordierite kiln shelves and alumina saggers, they:
Increased promotional ROI by 31%.
Reduced average discount depth.
Saw a 22% increase in rep-driven upsells.

Prioritizing product promotions by margin contribution isn’t just smart—it’s necessary. In markets where freight surcharges and inflation squeeze every dollar, promoting high-contribution SKUs gives distributors the double advantage of relevance and profitability. Don’t just push what moves. Push what matters.
