Psychological Pricing Edge: End prices at .97 instead of .99 for a subtle 2% conversion uplift without triggering algorithm penalties. This micro-optimization compounds across high-volume SKUs.

Metrics Optimization for Sustained Wins

ODR Prevention Protocol: Implement a daily 10-minute order review focusing on potential problem orders. Create a pre-shipment QA checklist with 3-point inspection: product condition, packaging integrity, and label accuracy. This prevents most A-to-Z claims before they occur.

Shipping Performance SOP: Maintain late shipment rates below 2% by batching orders in 2-hour processing windows. Process 50 units maximum per batch to ensure quality control. Use ShipStation’s automation rules to flag potential delays 24 hours in advance.

Inventory Velocity Management: Stock out = instant Buy Box loss. Set restock alerts at 14-day supply levels using this formula: (Average daily sales × 30 days) + 20% safety buffer.
