Need item ID or SKU on site items page

[autoglass99]

Hi, need help. I am trying to set up my online site.  The item ID or SKU is very important for me to see on the "site items" page.  The item ID is very important to see what's listed online.

I don't see an option to add a new column to this page.  Anybody have any suggestions.  Thank you.

Hello! It's easy to add your items sku number! If you go to your menu on square and click on manage items, you can click on individual items and will see right underneath the description will be the SKU or item number section. Super easy!
