Understanding Individual Unit Fulfillment vs. Bulk Operations
What is Eaches Picking?
Eaches picking refers to the fulfillment process of selecting individual units of products that are picked, packed, and shipped one at a time, rather than in bulk quantities like cases, cartons, or pallets.
Quick Example:
When a customer orders:
- 1 toothbrush
- 1 bottle of shampoo
- 1 phone case
Each item is an “each” that must be individually retrieved from storage, creating unique operational challenges compared to bulk picking operations.
Eaches vs. Other Picking Types
| Picking Type | Quantity | Typical Use | Complexity |
| Eaches | 1-5 units | E-commerce orders | High |
| Inner Pack | 6-24 units | Small retail restocks | Medium |
| Case | 25+ units | Wholesale orders | Low |
| Pallet | Full loads | Distribution centers | Very Low |
Why Eaches Matter in E-commerce
The E-commerce Revolution
67% of online orders contain only 1-2 items, making eaches picking the backbone of modern fulfillment operations. Here’s why it’s critical:
1. Customer Expectations Drive Demand
- Same-day delivery requires rapid individual item access
- Customization trends mean more single-item orders
- Gift purchases typically involve individual units
2. Market Growth Statistics
- E-commerce sales grew 14.2% in 2023, increasing eaches volume
- Mobile commerce accounts for 55% of orders (typically smaller quantities)
- Subscription boxes require precise individual item picking
3. Operational Impact
- 85% of warehouse labor in e-commerce facilities is dedicated to eaches picking
- Peak seasons can see 300% increases in individual item orders
- Returns processing primarily involves individual units
Storage Implications for Success
Effective eaches picking requires fundamentally different storage approaches:
Traditional Bulk Storage:
- Products stored in large quantities
- Optimized for case or pallet movement
- Limited individual item accessibility
Eaches-Optimized Storage:
- Individual item accessibility
- High-density organization
- Rapid retrieval capabilities
- Flexible reconfiguration options
The True Cost of Eaches Picking
Why Eaches Costs 5-7x More Than Case Picking
Understanding the cost implications helps justify investment in proper storage solutions and optimization strategies.
Cost Breakdown Analysis
| Cost Factor | Case Picking | Eaches Picking | Multiplier |
| Labor per Pick | $0.15 | $0.85 | 5.7x |
| Travel Time | 15% of cycle | 45% of cycle | 3x |
| Error Rates | 0.1% | 1.5% | 15x |
| Storage Density | High | Medium | 0.7x |
Hidden Costs of Inefficient Eaches Picking
1. Excessive Travel Time
- Pickers spend 40-50% of their time walking
- Poor storage organization increases travel distance by up to 200%
- Solution: Strategic placement of high-velocity items in accessible locations
2. High Error Rates
- Manual eaches picking averages 1-3% error rates
- Each error costs $15-25 to correct
- Annual impact: $50,000-150,000 for medium-sized operations
3. Labor Inefficiency
- Experienced pickers: 120-150 eaches per hour
- New workers: 60-80 eaches per hour
- Training costs: $2,000-3,500 per picker
4. Inventory Management Complexity
- SKU proliferation: 3-5x more storage locations needed
- Cycle counting: More frequent counts required
- Obsolescence risk: Higher with individual units
ROI Calculation for Storage Optimization
Example: 1,000 daily eaches orders
Current State (Poor Storage):
- Pick rate: 80 eaches/hour
- Labor cost: $18/hour
- Daily labor cost: $225
Optimized State (Proper Storage):
- Pick rate: 130 eaches/hour
- Labor cost: $18/hour
- Daily labor cost: $138
Annual Savings: $31,755 + reduced errors + improved customer satisfaction
Storage Requirements for Optimal Operations
Essential Design Principles
1. Accessibility
Every individual item must be reachable without moving other products.
Key Requirements:
- Eye-level placement for 80% of high-velocity SKUs
- No double-deep storage for eaches items
- Clear sight lines for easy identification
- Adequate aisle width (minimum 36 inches for manual picking)
2. Density vs. Accessibility Balance
The Storage Paradox: Higher density often reduces accessibility
Optimal Balance Strategies:
- ABC Analysis: Place A-items in most accessible locations
- Velocity-based slotting: Fast movers get premium real estate
- Seasonal adjustment: Reconfigure storage based on demand patterns
3. Ergonomic Considerations
Golden Zone Picking:
- Optimal height: 30-48 inches from floor
- Maximum reach: 24 inches from aisle
- Weight considerations: Items over 25 lbs need special handling
Impact on Productivity:
- Proper ergonomics increase pick rates by 15-25%
- Reduce worker fatigue and injury rates
- Improve accuracy through better item visibility
Technology Integration Requirements
Barcode Placement
- Multiple angles: Scannable from picking position
- Consistent positioning: Same location on similar items
- Size standards: Minimum 1-inch height for handheld scanners
