Overstocking Creep: The Silent Margin Killer Operations Managers Must Tackle in H2

As the second half of the financial year gets underway, Operations Managers across South Africa are under pressure to meet targets, optimise performance, and prepare for year-end reporting. But lurking quietly behind many supply chains is a profitability threat few talk about until it's too late: overstocking creep.

At Sengers LCA, we work with operations and logistics teams to proactively manage inventory and logistics performance. One of the most common—and costly—issues we see in H2 is the gradual buildup of stock beyond what the business actually needs. It’s easy to overlook, but its impact is serious.

In this post, we’ll unpack what overstocking creep is, why it happens, and how Operations Managers can take back control with smart logistics support and strategic inventory management.

What is Overstocking Creep?

Overstocking creep is the slow, often unnoticed accumulation of excess inventory—usually due to inflated forecasts, seasonal overcorrections, supplier minimums, or “just in case” ordering.

Unlike a single over-purchase, overstocking creep builds up over time. One extra pallet this month, a safety stock buffer the next—and before long, your warehouse is full, your cash flow is tight, and your operational KPIs are trending in the wrong direction.

Why It Peaks in the Second Half of the Year

The second half of the financial year (Q3 and Q4) brings unique pressures:

• Sales teams push for year-end targets, often driving aggressive order volumes.
• Operations overcorrect for H1 stockouts by increasing safety stock.
• Forecasts become harder to predict, especially in uncertain economic climates.
• Cash flow becomes a bigger concern, yet capital is tied up in slow-moving stock.

For Operations Managers, this creates a perfect storm: an overloaded supply chain at exactly the time the business needs agility and financial control.

5 Ways Sengers LCA Helps You Prevent Overstocking Creep

If you're an Operations Manager concerned about overstocking—or suspect it's already creeping in—here’s how Sengers LCA can help you regain control before year-end.

1. Mid-Year Inventory Health Check

We offer a comprehensive inventory audit to help you identify:

• Slow-moving or aged stock
• Overstocked SKUs vs demand trends
• High-cost inventory that isn’t earning its keep

Outcome: You’ll know exactly where excess is hiding—and how to fix it.

2. Forecast and Ordering Adjustments

We help you refine your forecasts for Q3 and Q4 using historical data and real-time trends. Together, we’ll update:

• Reorder points
• Safety stock levels
• Lead times

Bonus: We'll also help you prepare for seasonal spikes without overcommitting on stock.

3. Visualise the Cost of Excess Stock

Overstocking doesn’t just hurt cash flow—it quietly inflates warehousing, insurance, and logistics costs. Our reporting tools show:

• Logistics cost per unit
• Storage cost per item
• Aged inventory breakdowns

Result: Clear visibility to support better decision-making and internal conversations.

4. Lean Inventory Strategy for H2

We’ll work with your team to implement a “Lean, Not Low” inventory strategy—right-sized stockholding that meets service levels while freeing up working capital.

We also offer a free downloadable Lean Inventory Checklist to help your team spot overstocking signs early.

5. Supplier & 3PL Negotiation Support

In some cases, overstocking results from inflexible supplier agreements or high MOQs. We can support your procurement team with:

• Supplier term reviews
• Alternative 3PL or consolidation options
• Shared warehousing strategies to reduce overhead

KPIs to Watch Closely in Q3 and Q4

We help Operations Managers track and optimise key inventory metrics:

• Inventory Turnover Ratio
• Aged Inventory Percentage
• Days Inventory Outstanding (DIO)
• Logistics Cost as % of Revenue

With the right visibility, overstocking can be corrected before it impacts your margins.
