SAP Business One ROI – Inventory Optimisation
Inventory optimisation is typically one of the highest-value ROI drivers for SAP Business One because it reduces the capital tied up in stock while improving stock availability and reducing losses.
How SAP Business One Improves Inventory Performance
SAP Business One helps organisations:
- Improve demand forecasting
- Optimise reorder points and safety stock levels
- Increase inventory visibility across locations
- Reduce excess and obsolete inventory
- Lower stock carrying costs
- Reduce stock-outs and emergency purchases
- Improve inventory turnover
Key Inventory ROI Components
1. Inventory Holding Reduction
Many businesses carry more inventory than necessary due to poor visibility and planning.
Formula:
Inventory Reduction × Cost of Capital %
Example:
Current inventory value:
- R20 million
Inventory reduction:
- 15%
Inventory released:
- R3 million
Cost of capital:
- 12%
Annual benefit:
R3,000,000 × 12% = R360,000 per year
2. Reduced Carrying Costs
Inventory incurs costs for:
- Warehousing
- Insurance
- Handling
- Security
- Shrinkage
- Financing
Typical carrying costs range between 15% and 30% of inventory value annually.
Example:
Inventory reduction:
- R3 million
Carrying cost:
- 20%
Savings:
R3,000,000 × 20% = R600,000 annually
3. Reduced Obsolescence and Write-Offs
SAP Business One provides:
- Aging reports
- Slow-moving inventory analysis
- Better purchasing decisions
Example:
Current annual stock write-offs:
- R800,000
Reduction:
- 25%
Savings:
R800,000 × 25% = R200,000 annually
4. Fewer Stock-Outs
Improved planning reduces:
- Lost sales
- Expedited freight costs
- Emergency purchases
Example:
Lost sales due to stock shortages:
- R2 million annually
Gross margin:
- 30%
Stock-out reduction:
- 20%
Profit improvement:
R2,000,000 × 30% × 20% = R120,000 annually
