What is a SKU? (Understanding Stock Identifiers)
What is a SKU?
A SKU (Stock Keeping Unit) is a unique identifier assigned to each product or product variant. It is used to track and manage inventory. Each variation of a product (e.g. size, colour) should have its own SKU.
Why SKUs are Important
SKUs allow you to:
• Track inventory accurately
• Identify products quickly
• Sync products across systems (e.g. Shopify)
• Avoid confusion between similar items
Without SKUs, managing inventory becomes unreliable

Best Practices
Use clear and consistent naming.
• Include variation details (e.g. size, colour)
• Avoid duplicate SKUs
• Keep formatting consistent across your catalogue
Example:
• TSHIRT-WHITE-XS
• TSHIRT-BLACK-M
Important Notes
• Duplicate SKUs will cause conflicts in inventory and order matching
• SKUs are used to sync with external platforms — consistency is critical
• Changing a SKU after creation may break existing links to orders or systems
• SKUs should be simple, readable, and standardised
