If you only check gross margin at year-end, you’re flying blind. Here’s how to systemize profitability.
Your product catalog may be growing. Your top-line revenue might be rising. But unless you’re running disciplined, SKU-level margin health audits every quarter, you could be bleeding profit and not know it.
In glass, ceramics, and refractories distribution—where hundreds of SKUs have nuanced cost structures, customer-specific pricing, and varying fulfillment requirements—gross margin isn’t static. It’s dynamic. And auditing it systematically is the only way to protect your business in a tightening economy.
What Is a Margin Health Audit?
A margin health audit is a structured, periodic review of how your products and customer segments are performing from a profitability standpoint. Done quarterly, it reveals which products are still earning their keep—and which are dragging you down.
Here’s what it should include:
SKU-Level Gross Margin Analysis
Use 90-day trailing data. Rank all SKUs by gross margin contribution, factoring:
Current cost of goods (not legacy averages)
True landed cost (including freight, duty, packaging)
Selling price by customer tier
Look for red flags:
SKUs with declining volume but flat costs
High-sales-volume items with sub-10% margin
Custom items with labor-intensive handling and no surcharge
Customer Margin Contribution
Identify customers with declining profitability. You may find a legacy client ordering refractory anchors at 5% margin due to dated pricing agreements.
Use this insight to:
Renegotiate contracts
Offer incentives to shift volume to higher-margin items
Flag accounts that are consuming outsized service resources
Vendor Margin Review
Analyze supplier relationships. Are you sourcing high-cost glass laminates from a vendor that hasn’t adjusted pricing in your favor? Are ceramic imports still viable with 30% container inflation?
Look at rebates, returns policy, and volume discounts. Consider supplier consolidation for your top 20% of revenue-driving SKUs.
Operational Overlays
Don’t forget to factor in labor and handling. For example, ceramic tubes packed in breakable foam and requiring double boxing could have hidden fulfillment costs that shrink their margin below visibility thresholds.
Setting Up Your Margin Audit Process
The best-performing distributors create a repeatable audit rhythm:
Quarterly cadence, synced with financial closing cycles
Cross-functional input from sales, procurement, finance, and operations
Dashboards that auto-flag margin variance by SKU, category, and customer
Actions assigned: margin recovery plans, SKU rationalization, or price review triggers
Audits should also be tied to incentive systems. If your inside sales team is compensated on revenue only, they may prioritize low-margin SKUs. Audit data should inform smarter comp plans.

Profit isn’t a given—it’s an outcome of consistent margin management. A quarterly margin health audit arms your team with data to act early, price smartly, and protect your bottom line. Especially in glass and ceramic distribution, where material costs and freight swing wildly, this kind of discipline isn’t just nice to have—it’s survival. Start building your audit muscle now, before your next quote eats into next quarter’s margin.
