2. Add a variant (optional)
Size, colour or material — e.g. RED-L.

Dash, underscore or none; generate 1–20 sequential SKUs.
4. Copy or export
Use individual copy buttons or copy the entire list.
What makes a good SKU
A SKU is your internal product fingerprint. Done right, it makes picking, counting and reporting easier. Done wrong, it creates confusion across your warehouse and sales channels.
What makes a good SKU?
Short, consistent, readable, unique. No spaces or special chars. Prefix = brand/supplier; middle = category/type; suffix = variant.
Avoid manufacturer part numbers
They can change or be non-unique. Build your own convention instead.
SKUs vs barcodes
SKU is your internal identifier; barcode encodes it for scanning. One SKU = one barcode.
Keep it readable
Someone should be able to read a SKU on a picking list and know roughly what it is.

Frequently asked questions
What is a SKU?
A Stock Keeping Unit (SKU) is a unique internal code that identifies a specific product variant. Every distinct product—size, colour, material—gets its own SKU.
What is a good SKU format?
A good SKU has 3–4 meaningful segments: brand prefix + category + variant + sequence number. Example: NIKE-SHOE-BLK-10-001. Keep it under 20 characters and avoid spaces.
What's the difference between a SKU and a barcode?
A SKU is your internal name for a product. A barcode encodes that SKU (or another number) so it can be scanned. Your inventory system links the two.
Should SKUs be case-sensitive?
No. Use uppercase letters only to avoid confusion and ensure compatibility across systems.
Can I change SKUs later?
Technically yes, but it creates reconciliation problems. Set up a consistent SKU format before you start and stick to it.
