## What a SKU is

A SKU (stock-keeping unit) is your internal code for a product or variant. Unlike a manufacturer's barcode, you control it. A clean SKU scheme makes picking, counting, and reporting faster and less error-prone. The free [SKU Generator](https://www.pyalm.com/free-tools/sku-generator) builds consistent codes from your own segments.

## Anatomy of a good SKU

Build SKUs from meaningful segments — for example category, product, and variant — followed by a sequence number: SHIR-OXFD-BLUM-001. Keep them short, uppercase, free of spaces and special characters, and consistent in structure.

## Rules worth following

- **Don't start with zero** in a way that spreadsheets strip.
- **Don't embed prices** — they change.
- **Keep SKUs distinct from barcodes** (UPC/EAN). They serve different purposes.
- **Be consistent** — the same segment order every time.

## SKUs and barcodes work together

Your SKU is internal; the barcode is for scanning. Generate scannable labels with the [Barcode Generator](https://www.pyalm.com/free-tools/barcode-generator) once your SKUs are set.
