Track every SKU in one system

Great SKUs are the foundation of a well-run inventory system. Once you have them, VNDLY helps you track every SKU's stock levels, sales velocity, purchase orders and supplier prices — across every warehouse and sales channel.

How to use this generator

  1. 1. Add a brand or category prefix

    Example: ACME for brand, or SHIRT for category.

  2. 2. Add a variant (optional)

    Size, colour or material — e.g. RED-L.

  3. 3. Choose separator and quantity

    Dash, underscore or none; generate 1–20 sequential SKUs.

  4. 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.
