Set up all items as add-on items
When you set up your items, BackerKit recommends creating all items as add-on items. Even if you don’t plan on selling items individually, setting up your items this way gives you the flexibility to offer these items separately at a later date.
When you create an item in BackerKit with the Item Generator, it’s automatically created as an add-on item. As long as you don’t change this setting, your items will be set up correctly.
