ABC SKU Analysis: Identify Your Fast Movers, Money Makers, and Time Wasters

As warehouse consultants, we’ve seen this play out hundreds of times: A company with a solid team, a reliable ERP, and thousands of SKUs — yet inventory is bloated, pickers are walking miles, and leadership is asking why working capital is tied up in slow movers.

If you’re an inventory analyst, senior buyer, or CFO, you likely understand ABC inventory principles. But understanding isn’t enough. To drive real operational ROI, ABC SKU Analysis needs to be applied in context — with visibility, rigor, and alignment across departments.

In this post, we’ll walk through a results-driven approach to ABC analysis — using practical examples, real-world metrics, and visual tools — to help you separate your fast movers, money makers, and time wasters.

Why ABC SKU Analysis Still Delivers ROI in 2025

ABC Analysis — categorizing items into A (high value/velocity), B (moderate), and C (low) — is nothing new. But when applied with data and visual tools, it becomes a strategic decision-making engine.

📈 Companies that implement SKU stratification properly often see:

  • 20–35% reduction in average pick times

  • 10–15% lower inventory holding costs

  • Improved vendor negotiations and procurement cycles

  • Fewer stockouts of critical SKUs

As Gartner notes in their supply chain optimization reports, organizations that pair inventory classification with warehouse slotting outperform their peers in inventory turns and space utilization.

Real-World Example: ABC Analysis in a Florida Manufacturing Facility

A mid-sized HVAC distributor in Central Florida was struggling with long pick times and constant reordering of key SKUs — despite having over 3,000 active items.

We ran a free ABC SKU Analysis using their sales data, which revealed:

  • Only 9% of SKUs generated 78% of revenue (Category A)

  • Category C made up over 60% of SKUs but contributed <5% of revenue

  • Pickers were traveling 45% more than necessary due to poor slotting

✅ Changes Implemented:

  • A-items were moved to golden zones (waist-high, near packing)

  • B-items were slotted mid-range

  • C-items moved to upper shelving or offsite storage

Result: 27% faster picking, fewer replenishments, and a 15% reduction in overall inventory carrying cost within 6 months.

Classification % of SKUs % of Value Pick Frequency Suggested Action
A ~10% 70–80% Very High Slot in golden zone for speed; always in stock
B ~20% 10–20% Moderate Review quarterly; keep nearby but not prime
C ~70% <10% Low Move to upper/bulk storage; monitor for obsolescence

Checklist: How to Conduct Your ABC SKU Analysis

1. Extract Clean Historical Sales Data
Pull 12–18 months of order history — focus on revenue, units sold, and order frequency per SKU.

2. Rank SKUs by Value Contribution
Sort by total revenue or picks — cumulative percentage helps define A, B, and C.

3. Reevaluate Each Category Quarterly
Use rolling data to adjust for seasonality or market shifts.

4. Align Cross-Functionally
Share findings with procurement, operations, and finance. Set reorder points and MOQs based on category.

5. Take Action
Update slotting, purchasing logic, and reporting dashboards. Consider setting KPIs for each category.
