Example calculation

Example: Brand ACME, category SHOES, product Runner, color Black, size 42 can become ACME-SHOES-RUNNER-BLACK-42.

Practical use and limits

This page is built for cleaning up product operations tasks such as SKU, catalog or marketplace preparation without storing catalog data. The calculation is intentionally visible and described above so you can sanity-check the result instead of treating it as a black box.

Limit: generated catalog values should be checked against your actual inventory, marketplace and ERP rules. For important decisions, use this result as a planning aid and verify it against the relevant source of truth.

SKU Generator: practical guide

A SKU should help operations, not decorate a catalog. Good SKUs are readable enough for humans and consistent enough for systems.

Use the generator to create drafts, then check them against your warehouse, marketplace and ERP rules before importing.

Real examples

Shoe catalog

Input: ACME, runner, black, 42

Result: ACME-RUNNER-BLACK-42

Variant family

Input: Brand + product + color + size

Result: stable pattern across variants

Practical notes

Keep the pattern short and predictable.
Avoid characters that break CSV imports or barcode systems.
Do not encode too much business logic into the SKU.

Common mistakes

Making SKUs too long to read.
Changing the pattern mid-catalog.
Assuming generated SKUs are automatically unique.

Are generated SKUs guaranteed unique?

No. Use the random suffix to reduce collisions, then check against your catalog.

Can I use underscores?

Yes. Choose dash, underscore or no separator.

Are inputs stored?

No. SKU generation runs locally in your browser.
