Bundles are essentially 'combo' items created in the POS.
Bundles come to Doshii with included options. For example, a 'hamburger combo' provides a choice of burger (hamburger, cheeseburger, etc.), extras, drinks, size of fries, etc for a set price - often discounted because they are purchased together.
Bundles are not common in Square POS menus because they can currently only be created via API.
Due to this, the Doshii-Square integration does not support bundles.
