SKU generator for a catalogue your team can read

Choose a stable attribute order, generate variant codes and check them against an existing list before export. A SKU is an internal reference; it is not a UPC, EAN, GTIN, or automatically scannable barcode.

Convention
Duplicates are checked after case and separator normalization.

Internal code design

Encode what identifies the variant

A useful code tells a stockroom worker which catalogue variant they are holding without hiding the meaning in a random string. Select only attributes that remain stable enough to help a person and a system distinguish the item.

  • Keep price and warehouse location outside the SKU when they can change.
  • Give colour, size, pack, or revision a consistent position.
  • Treat a discontinued or replacement variant as a deliberate catalogue decision.
Before import

Find collisions before stock moves

The generator compares new codes with the list you provide, normalizes case and separators, and reports a collision instead of silently overwriting an item. Export the input-to-output mapping so the catalogue owner can review it before import.

  • A different retailer can use a different SKU for the same manufacturer product.
  • A generated SKU does not create a global identifier.
  • Barcode encoding is a separate tested step after the internal code is approved.

Continue from calculation to workflow

Use the result as an input to planning—not as a standalone system decision.
