Import combos using a spreadsheet to add multiple combos to your Back Office at once.
Before you start importing combos, it is important to export your existing items. This export is your back-up.
Since combos are considered items themselves, follow the Importing and exporting items article. There you will find information on how to export items and use the item and menus import template.
In the template, use the tabs labeled Step b-Create item groups and Step 2c - Create Combos to create combo. Keep in mind that the items used for the combo must already exist in the Back Office or you can use the template to create items, combos, and menus all at once.
