You can use related items in your web store to cross-sell products that complement each other.
For example, an electronics web store created a related items group containing cables, extension cords and surge protectors. When a customer views a monitor on the site, the list of related items displays, and she can navigate to the additional products she needs.
There are two ways you can use related items in NetSuite:
Related Item Groups – You first create groups of related items. Then, you add these groups to items you sell in your website.
Related Items – You can also associate individual items to items you sell on your website.
