This case study explores how SummitPro Distribution, a regional building supply distributor, transformed its operations to not only survive but thrive during a period of high volatility. The result?

A 37% improvement in on-time delivery

A 22% reduction in emergency procurement costs

Improved contractor loyalty during supply chain chaos

🏢 Company Snapshot: SummitPro Distribution

Headquarters: Charlotte, NC

Industry: Building materials distribution (roofing, framing lumber, insulation, siding)

Markets: Mid-Atlantic and Southeastern U.S.

Challenge: Frequent supply disruptions causing stockouts, delivery delays, and rising freight costs

🎯 The Goal: Proactively Prepare for Disruption Without Inflating Costs

SummitPro wasn’t looking to stockpile or overspend—they wanted a scalable, cost-smart strategy that would allow them to respond faster, serve customers better, and protect their margins.

🧠 Strategy 1: Smarter Inventory Planning Using Tiered Risk Models

Challenge: Blanket safety stock was tying up capital—and still leaving them vulnerable.

What They Did:

Conducted a SKU-level risk analysis (based on supplier reliability, lead time, and demand volatility)

Classified inventory into three tiers:

Tier 1 (Critical): Maintained higher safety stock

Tier 2 (Moderate): Set dynamic reorder points based on forecast

Tier 3 (Low Risk): Used just-in-time replenishment

Result:

📦 Reduced inventory carrying costs by 15% while improving service levels on key items.

🤝 Strategy 2: Supplier Diversification and Partnership Building

Challenge: Overdependence on single-source suppliers was causing bottlenecks.

What They Did:

Developed a multi-vendor sourcing plan for top 20% of high-risk products

Built relationships with regional backup suppliers

Held quarterly performance reviews and shared demand forecasts with key partners

Result:

🔁 Gained supply flexibility and avoided stockouts during a major port delay in Q3.

📡 Strategy 3: Real-Time Visibility and Alerts

Challenge: Delays were going undetected until customers complained.

What They Did:

Integrated ERP, WMS, and logistics platforms for real-time tracking of orders and inventory

Set up automated alerts for stockouts, late deliveries, and PO delays

Equipped customer service teams with live ETA and order status tools

Result:

📊 Customer escalations dropped by 42%, and branch teams could make proactive calls before issues arose.

🚛 Strategy 4: Logistics Flexibility With Local Carrier Network

Challenge: Freight delays and driver shortages were hitting hard in rural markets.

What They Did:

Partnered with local and regional LTL carriers as backup

Added a local courier network for last-mile flexibility

Introduced multi-drop routing to optimize fuel and labor use

Result:

🚚 Maintained 95%+ on-time delivery even during a regional fuel shortage.

🧾 Strategy 5: Scenario Planning and Rapid Response Protocols

Challenge: Leaders and teams felt unprepared for major disruptions.

What They Did:

Conducted quarterly tabletop exercises (e.g., supplier shutdown, major storm, cyberattack)

Created playbooks with escalation paths and decision matrices

Defined “disruption response teams” at HQ and branch levels

Result:

🔧 During a severe storm in the Southeast, SummitPro re-routed deliveries, adjusted stock transfers, and maintained full operations within 48 hours.

💡 Bonus Move: Proactive Customer Communication

Challenge: Contractors were frustrated by lack of transparency.

What They Did:

Set up automated text/email alerts for key customer orders

Trained sales reps to deliver early disruption warnings and offer alternatives

Built jobsite pickup options as a backup when delivery was delayed

Result:

👷 Contractor NPS rose by 18 points in just six months.
