Products catalogue visibility
“Can a customer browse/ buy items that are not listed on their group product catalogue price list?”
Customers sees all products that are listed with a price in their Group product catalogue page.
You can give them as big (or small) a product catalogue as you want e.g could be 20 products, 800 products or 5000+ products.
Each product listed on the product catalogue needs to have a price to be displayed to the customer on your store.
If you would like them to browse all your products you will need to enter a price to all products on the product catalogue page of your customer store group.
