You can add an upsell at the end of every transaction taken on the kiosk. When offering an upsell, one item will appear that is not already in your customer's cart from the upsell group you have already created.
To create an upsell group:
- Log in to the GRUBBRR backend
- Select 'Menu' from the left sidebar menu
- Select 'Upsells' from the dropdown
- Select '+Create Upsell'
- Select the items you wish to offer as upsells from the 'Available Items' column
- Select 'Add New Upsell'
