Inventory problems rarely start as a crisis. They build silently — excess stock filling warehouses, frequent stockouts frustrating customers, blocked working capital, and declining service levels.
At Faber Infinite Consulting, we’ve seen this pattern across manufacturing, FMCG, and industrial sectors. What begins as “just a planning gap” quickly turns into a profitability issue.
In this blog, we share real case studies on how professional inventory consulting services helped companies fix inventory problems — using structured methods, data-backed insights, and globally recognized standards.
Why Inventory Problems Hurt Business Performance
According to the Supply Chain Management Professionals (CSCMP) (Council of Supply Chain Management Professionals), inventory carrying costs typically range between 18%–30% of total inventory value annually.
Similarly, research insights published in the Harvard Business Review (Harvard Business Review) highlight that poor working capital management directly reduces competitiveness and return on invested capital (ROIC).
Inventory issues impact:
- Working capital
- Service levels
- Production continuity
- Warehouse space utilization
- Cash flow stability
This is where an inventory optimization consultant brings structure and measurable improvement.
Case Studies: How Consultants Fixed Inventory Problems
Below are real-world structured case examples from our consulting interventions.
Case Study 1: Excess Inventory Blocking ₹18 Crore Working Capital
| Category | Details |
| Industry | Automotive Components |
| Problem | 42% excess inventory, slow-moving SKUs, blocked capital |
| Consultant Approach | ABC-XYZ analysis, safety stock redesign, demand variability study |
| Tools Used | Inventory control techniques, ERP data analytics |
| Results | 28% inventory reduction in 6 months, ₹5.2 Cr working capital released |
What Was Happening?
The company believed higher inventory meant better service levels. However:
- 38% SKUs had zero movement in 90 days
- Forecast accuracy was below 60%
- Safety stock was based on assumptions, not statistical models
Consultant Intervention
As an inventory management consultant, we applied:
- ABC classification (value-based segmentation)
- XYZ analysis (demand variability mapping)
- Statistical safety stock calculation
- MOQ rationalization
- Supplier lead-time validation
Outcome
- 28% reduction in total inventory
- Warehouse congestion reduced by 35%
- Service levels improved from 89% to 96%
This is a practical example of how inventory consultants reduce excess stock costs.
Case Study 2: Stockouts Despite High Inventory
| Category | Details |
| Industry | FMCG Manufacturing |
| Problem | Frequent stockouts with high overall inventory |
| Consultant Approach | Demand planning redesign, replenishment cycle optimization |
| Tools Used | Supply chain & inventory consulting framework |
| Results | 22% service level improvement, 18% reduction in urgent dispatch costs |
Root Cause Identified
- No SKU prioritization
- Warehouse management gaps
- Unstructured reorder point system
Inventory was high — but wrongly distributed.
Expert Strategy Applied
We implemented:
- Service-level-based inventory models
- Multi-echelon inventory planning
- Reorder point optimization
- Daily Work Management dashboards
This aligns with global supply chain principles recommended by APICS, now part of ASCM (Association for Supply Chain Management).
Results
- 22% increase in fill rate
- 18% reduction in emergency freight
- 15% reduction in dead stock
This demonstrates effective inventory optimization solutions for manufacturing companies.
Case Study 3: Warehouse Chaos & Poor Inventory Visibility
| Category | Details |
| Industry | Engineering Manufacturing |
| Problem | 11% inventory mismatch, audit failures |
| Consultant Approach | Warehouse layout redesign, cycle counting system |
| Tools Used | Lean inventory strategies, barcode tracking |
| Results | Inventory accuracy improved to 98.5% |
Key Gaps Found
- No bin-level mapping
- Manual tracking errors
- Irregular cycle counting
Consulting Intervention
We implemented:
- 5S-based warehouse zoning
- Barcode-based inventory tracking
- Structured cycle count calendar
- Root cause analysis of variances
These are industry-standard inventory control techniques aligned with ISO quality system requirements.
Measurable Impact
- 98.5% inventory accuracy
- 30% faster picking time
- 25% improvement in warehouse space utilization
This is how consultants improve supply chain and inventory visibility.
