Inventory & Replenishment Management: Practical Formulas
Key Formulas:
Daily Sales (DS) = Last 30 days’ sales ÷ 30
Lead Time = Production time + first-leg transit + customs clearance
Safety Stock (SS) = DS × Variability Days (7–15 days or more)
Reorder Point (ROP) = DS × Lead Time + SS
Practical Advice:
New SKUs: Increase SS (14–30 days), use small batch/frequent replenishment
Stable SKUs: Maintain 30–45 days FBA safety stock + China warehouse buffer
Peak season: Book shipping & production 45–90 days in advance

Supply Chain Digitization (Short- & Mid-term Implementation)
| Timeline | Key Steps |
|---|---|
| 0–3 months | Standardize SKUs, deploy basic WMS, create QC checklists |
| 3–9 months | Integrate logistics API, auto-replenishment alerts, dashboard KPIs |
| 9–18 months | Implement sales forecasting, cost simulation, exception alerts, AI-assisted decision-making |
Optimizing the supply chain and controlling costs are crucial.
Inventory Segmentation & Prioritization
Not all SKUs perform equally. Categorize inventory based on sales velocity and margin:
High-velocity / high-margin SKUs: Keep at least 45 days of FBA stock; consider multiple replenishments per month.
Medium-velocity / seasonal SKUs: Store in China warehouse as a buffer; use sea freight for cost-effective bulk replenishment.
Low-velocity / niche SKUs: Just-in-time air shipment is preferable to minimize storage fees.
Benefit: Reduces overstocking and storage costs while ensuring high-demand items are always available.
Packaging & Dimensional Weight Optimization
Shipping fees, especially for air freight and couriers, are volume-sensitive:
Use right-sized boxes or polybags.
Consolidate multiple SKUs in a single case when possible.
Avoid excess filler material that adds volume without protection.
Tip: A 10% reduction in package volume can reduce air freight cost by up to 15–20%.
Multi-Warehouse Strategy
Utilize both China and overseas warehouses:
China warehouse: Acts as a buffer for production delays and shipping fluctuations.
FBA warehouses: Ensures rapid fulfillment and improved delivery metrics.
Overseas warehouse for peak seasons: Avoids high shipping surcharges and lost sales.
Benefit: Balances cost efficiency and service reliability.
Data-Driven Replenishment & Forecasting
Monitor SKU-level sales trends using Helium10, Sellerboard, or WMS.
Forecast demand spikes based on seasonal trends, promotions, or market shifts.
Automate reorder alerts to avoid manual errors.
Benefit: Optimized stock levels, lower emergency shipping costs, improved cash flow.
Consolidated Multi-SKU Shipments
When sourcing from multiple factories:
Consolidate SKUs in a central warehouse before shipping to FBA.
Use pallets and master cartons to reduce handling and shipping fees.
Coordinate arrival timing to prevent partial shipments triggering additional FBA fees.
Benefit: Reduced per-unit costs, simplified customs documentation, fewer handling errors.
Dynamic Freight Cost Management
Regularly compare multiple freight forwarders to secure competitive rates.
Lock in rates via forward contracts or long-term agreements.
Ship off-peak to avoid seasonal surcharges.
Benefit: Predictable logistics costs and improved profit margin stability.
Risk Management & Contingency Planning
Even with optimization, risks exist:
Delayed shipments: Maintain China warehouse buffer, stagger replenishment.
Customs clearance issues: Use DDP or experienced brokers.
Label or packing errors: Implement pre-shipment QC checks and photo verification.
Tip: Document every exception and create standard operating procedures for recurring issues.
Performance Metrics & KPIs
Track KPIs to ensure your supply chain is operating efficiently:
Lead time adherence: % of shipments arriving on schedule.
Stockout rate: % of SKUs running out of stock in FBA.
First-leg cost per unit: Freight cost divided by units shipped.
Order accuracy: % of SKUs shipped without packing errors.
Benefit: Quantifies performance, identifies bottlenecks, and informs decision-making.
Continuous Improvement & Digitization
Supply chain optimization is ongoing:
Integrate ERP or WMS for automated inventory and shipment tracking.
Implement AI-assisted demand forecasting to anticipate market shifts.
