Best Practices for SKU Naming

1

Keep it Readable

Don't use random numbers. `TSHIRT-RED-L` is better than `1058392`. It should make sense to human readers.

2

Short and Sweet

Keep usage between 8-12 characters. Long SKUs get cut off in reports and labels.

3

Avoid Confusing Characters

Stay away from 'O' (letter) and '0' (zero), or 'I' (letter) and '1' (number). They look the same on labels.

4

Cascading Information

Start with the broadest category (Brand/Dept) and move to specific attributes (Color/Size). This helps in sorting.

Frequently Asked Questions

What is the difference between SKU and UPC/EAN?

UPC (Universal Product Code) and EAN are standardized global barcodes printed on products by manufacturers. SKUs are internal codes you create for your own business use. You can change your SKUs, but UPCs are fixed.

Can I use the same SKU for different products?

No! Every unique product variant (e.g., Small vs Medium) must have a unique SKU. Using duplicate SKUs will cause major inventory errors.

Frequently Asked Questions

What is a SKU and why do small businesses need one?

SKU stands for Stock Keeping Unit — a unique alphanumeric code assigned to each distinct product variant you sell. SKUs allow you to differentiate between products that might share a similar name but differ in size, colour, weight, or packaging. For example, a "Cotton T-Shirt" might have separate SKUs for each size and colour combination. Without SKUs, tracking inventory accurately — especially across hundreds of products — becomes extremely difficult and error-prone. Even small shops benefit from SKUs because they speed up billing and prevent stock count errors.

How should I structure my SKU codes?

A good SKU structure is short, meaningful, and consistent. A common format is: [Category Code]-[Brand/Supplier Code]-[Product Code]-[Variant]. For example, a medium blue cotton shirt from brand XY might be: APP-XY-CTSH-MBL. Keep SKUs under 12 characters where possible for readability, avoid special characters other than hyphens, and use a consistent naming convention across your entire product catalogue. The Wiseventory SKU generator above creates structured codes based on the attributes you provide, following best practices for retail inventory management.

Is a SKU the same as a barcode?

No. A SKU is your internal code for a product — it is defined by you and is unique to your business. A barcode (such as EAN-13 or Code 128) is a machine-readable representation of a number that can be scanned by a barcode reader. You can print a barcode that encodes your SKU so that scanning it fills in the product details during billing. In practice, many businesses use their SKU as the number encoded in the barcode, creating a single identifier that works both for human reading and barcode scanning.

How many SKUs can I manage in Wiseventory?

Wiseventory does not impose a limit on the number of SKUs (products) you can add to your account. Whether you manage 50 products or 50,000, the search, filtering, and billing performance remains fast. Large product catalogues can be imported in bulk via CSV/Excel upload, so you don't need to add each product manually. For businesses with large catalogues, Wiseventory also supports product categories, tags, and custom attributes to organise inventory efficiently.
