Why you need SKUs

Having consistent SKUs across sales channels is essential when using Listing Mirror.

What is a SKU?

A SKU, or Stock Keeping Unit, is a unique identifier assigned to each product in your inventory. 

Ecommerce sellers frequently embed key information into their SKUs like vendor, buy cost, purchase location, and more. For example, a seller who sourced red-rimmed reading glasses in September 2024, from a vendor in Hoboken, NJ might create the following SKU: Red_glasses_hobo0924


Why are SKUs important? 

SKUs are the identifiers that it make it possible for you to distinguish between different products, track inventory levels, and manage orders.  


How does Listing Mirror use SKUs?

Listing Mirror uses a SKU-based system that allows for seamless synchronization of your listings, inventory levels, and sales data across all platforms.


Will my SKUs work with Listing Mirror?

SKUs that match across marketplaces will ensure that your inventory and order management processes run smoothly and efficiently.

If SKUs do not match, you'll need to manually link them later in Listing Mirror. While linking SKUs manually can be a time-consuming process, once it's completed, you should not have to do it again.


What if some of my products don't have SKUs?

Certain marketplaces, such as eBay, do not require the use of SKUs. When Listing Mirror completes the initial process of importing listings, any product without a SKU will have one assigned automatically. You can spot these SKUs easily because they begin with "LM-".
