We usually use a separate field to track UPC of the product.

Product Description

Product description or explanation is used for the listings.


Dropshipping is becoming a crucial facilitator for online retailers. If your product has the dropshipping option, you should define this in your product SKU master data.

Product Dimensions

Product dimensions such as weight, height, length and width are very useful to calculate storage usage, carrier rate and the packing box for the order. The dimensions are also used by the directed putaway algorithm to suggest a suitable warehouse location for our receipts.

Inventory Attributes

Inventory attributes such as lot batch number, serial number and expiration date are also useful for some industries. For instance, if you are selling food products, you need to track loot number and expiration date for food safety regulations. If you are selling electronics product, you may activate serial number tracking.

Kitting and Bundling

If the product is a kit, product SKU master data should include this information as well. You should enter the components of the kit and the required quantities. Your inventory management system uses this information to track kit product inventory and component product inventory.

How do I make a product SKU?

There are some important points you need to consider when generating SKUs. First of all, the format should be easy enough for everyone to understand. It is best practice to avoid using zeros, special characters, and letters that resemble numbers to avoid any confusion. Most SKUs have 8-12 characters, you need to make sure to start with the most important identification depending on your item such as warehouse code, supplier information, and follow by the other required relevant information.

What is the difference between a SKU and UPC number?

The main difference between SKU and UPC codes is that UPCs are barcodes that should be purchased and licensed globally. UPCs are unique for a product and do not change depending on the seller, while SKUs are generated internally within the company and can change from one seller to another as they are mostly used for internal operations. The other difference is UPC barcodes must have 12 digits consisting of only numbers but SKUs don’t have a specific character limitation and can contain both numbers and letters.
