SKU generators give you the overview you need to stay in stock

What is a stock-keeping unit (SKU) and what are they used for?
SKUs or stock-keeping units are internal product codes you can use to identify and track product variants. They are typically alphanumeric and represent characteristics of each variant to make them easier to identify. With an SKU generator, you can easily keep track of item availability and get more control over your inventory.

Reasons to use an Excel SKU generator like this free tool
Using a single tool to generate SKUs reduces the risk of human error and ensures that all your teams use the correct references when referring to materials and products.
- Easily manage stock availability and track product SKUs
- Identify the products that have the highest profit margins
- Keep your team aligned by using the same product references

You can also track and assign SKUs with manufacturing software
Spreadsheets are static, but your inventory is not. With Katana, you can effortlessly manage up to 20,000 unique SKUs, making it possible to continuously add products and materials to your catalog without affecting your account’s performance. No risk of corrupted Excel spreadsheets or manual updates required.
