SKU Management
Stock Keeping Unit
The system of creating, organising, and tracking Stock Keeping Units -- unique identifiers assigned to each distinct product variant for inventory management and sales tracking.
In-Depth Explanation
SKU (Stock Keeping Unit) management is the practice of creating and maintaining unique identifiers for every distinct product variant a business sells. A well-structured SKU system enables accurate inventory tracking, sales analysis, and operational efficiency.
SKU system components:
- SKU format: Structured code encoding product attributes (e.g., SHT-BLU-M = Shirt-Blue-Medium)
- Naming convention: Consistent rules for how SKUs are created
- Variant tracking: Separate SKUs for each size, colour, and style combination
- Barcode mapping: Linking SKUs to scannable barcodes
- Cross-reference: Mapping internal SKUs to supplier SKUs and marketplace identifiers
SKU naming best practices:
- Start with a category or brand prefix
- Include key differentiating attributes (colour, size, material)
- Keep SKUs concise (8-12 characters)
- Avoid characters that cause confusion (0 vs O, 1 vs l)
- Use hyphens or consistent separators
- Document the convention for team reference
- Plan for future expansion (leave room for new attributes)
SKU management challenges:
- Proliferation: Too many SKUs creating operational complexity
- Cross-channel mapping: Different identifiers across marketplaces
- Bundle tracking: Managing component-level inventory for bundles
- Variant explosions: Colour x size x material combinations
- Discontinuation: Properly retiring old SKUs
- Data quality: Maintaining accurate SKU data across systems
SKU analysis for business decisions:
- Sales velocity by SKU (fast vs. slow movers)
- Margin analysis by SKU
- Inventory turnover rate per SKU
- Stock coverage (days of stock remaining per SKU)
- ABC analysis (categorising SKUs by revenue contribution)
- Dead stock identification (SKUs with no sales)
Business Context
Effective SKU management prevents the common problem of 80% of revenue coming from 20% of products while the remaining SKUs tie up capital in slow-moving inventory.
How Clever Ops Uses This
Clever Ops helps Australian e-commerce businesses implement structured SKU management systems that connect across all sales channels and inventory locations. We design SKU conventions, set up cross-channel SKU mapping, and build analytics dashboards that reveal which products drive profit and which drain resources.
Example Use Case
"A fashion retailer restructures their SKU system from random codes to a structured format (BRD-CAT-COL-SZ), enabling automated inventory reporting, faster pick-and-pack, and accurate cross-channel stock management."
