Can AI Predict What a Customer Will Buy Next? A New Era for Inside Sales

By Glazix | June 10, 2025

Inside sales teams in the raw materials space—whether dealing in PVC conduit, float glass, engineered ceramics, or hot-rolled steel—are under constant pressure to grow wallet share. But cross-selling in these sectors isn’t easy. Reps must navigate complex BOMs, product specs, irregular buying cycles, and fragmented customer histories across multiple SKUs and sites.

Now, artificial intelligence is giving sales teams a powerful edge: the ability to predict what each customer is likely to buy next—and when.

Why Traditional Selling Falls Short

In most distribution environments, reps rely on gut instinct and limited CRM filters to guess at cross-sell opportunities:

“They bought X—maybe they’ll need Y.”

“This customer ordered last month, time to follow up.”

“Let me check what they bought last year.”

These tactics are manual, inconsistent, and often miss high-value opportunities hiding in plain sight.

How AI Predicts Buying Behavior

AI systems ingest and analyze vast quantities of data to generate customer-specific product recommendations and timing signals. These inputs include:

Transactional history (SKUs, volume, frequency, seasonality)

Quote and inquiry data

Industry and segment trends

Buying behavior from similar customers

Material substitution logic and project lifecycles

CRM activity, delivery cadence, and stock levels (if integrated)

From this, the AI engine builds a predictive profile for each account—suggesting not just what they might buy, but when they’re most likely to need it.

Use Case: A Building Materials Distributor Cross-Selling OSB and Fasteners

A national distributor supplying OSB, sheathing, and connectors used AI to analyze its pro contractor accounts. The model identified a pattern: customers who bought OSB panels in volume often needed structural fasteners and sill seal within 5–7 days.

Inside sales reps began proactively offering bundled quotes at the right moment—boosting order size and reducing pricing-only RFQs.

Results:

19% lift in average order value

13% improvement in quote-to-order ratio

2x increase in attach rate for secondary SKUs

What This Means for Inside Sales Teams

Smarter outreach: Call the customer with a timely, relevant offer—not just a check-in.

Higher close rates: Suggest the product they’re already thinking about, before the competition does.

Reduced churn risk: Stay in front of the buyer with tailored recommendations that show you know their business.

Stronger margins: Proactively sell value-added items—don’t wait for a request.

AI as a Sales Co-Pilot, Not a Replacement

This isn’t about automating human interaction—it’s about amplifying human insight. AI points to the best opportunity; the rep closes the deal by bringing context, relationship, and service.

For example, an AI tool might suggest that a glass shop customer who regularly buys IGU spacers is likely due for low-E coated stock based on seasonal install patterns. The rep can follow up with a tailored quote, availability details, and even suggest a volume incentive.

The Bottom Line

In raw materials sales, success isn’t just about speed. It’s about anticipation. AI lets inside sales teams stop reacting to RFQs and start shaping demand—quote by quote, call by call.

Yes, AI can predict what a customer will buy next. But more importantly, it helps your team be ready with the right offer, at the right time, with the right margin. That’s the new playbook for proactive growth in industrial sales.
