There are two ways to Batch Edit Prices:
Batch Edit
Matrix View:
[ Items > Items Prices > Batch Edit ]: A matrix view of multiple customers and multiple items.
If the amount of data on the screen is too large, it may cause the page to become unresponsive.
One Item, all customers:
[ Items > Items Prices > by Item ]: If a Visibility Template is attached, the eye icon shows whether the item is visible or not. You cannot edit the visibility setting of the template here, as it would impact all customers with that template attached. The same applies to Price List.
